Chapter IX: Front Matter (9)

Suppose a straight line coincident with the vesico-vaginal wall (Fig. 1) to be continued through the cervix to the sacrum. This line represents approximately the antero-posterior diameter of the pelvis. The length of the vesico-vaginal wall is two and a half inches, and, supposing the cervix to be just midway between the symphysis and the sacrum, the distance from its posterior wall to the sacrum must also be two and a half inches. Add to the sum of these two parts of this antero-posterior diameter one inch for the cervix, and the antero-posterior diameter of the pelvis becomes six inches instead of the normal four and one-third; which proves that the cervix must normally be much nearer to the hollow of {148} the sacrum than to the symphysis. Since the length of the vesico-vaginal wall plus the diameter of the cervix measures three and one-half inches, it follows that the distance from the posterior wall of the cervix to the hollow of the sacrum must be the difference between four and one-third and three and one-half inches, or five-sixths of an inch.

Again, suppose the uterus (Fig. 1) to be carried bodily upward and backward, its axis remaining the same, until the cervix reach its normal position near the hollow of the sacrum; then would the body of the uterus impinge upon the bony sacrum. It is therefore clear that the anteversion must be the normal position, because the uterus and sacrum would otherwise occupy the same space.

Fig. 2 represents, according to Schultze,[2] the location and position of the virgin uterus and its surroundings, the bladder, rectum, and vagina being empty and collapsed. The angle of about 90° which the cervix forms with the vagina measures the forward inclination of the cervix, but is subject to slight variations in consequence of the physiological {149} movements of the uterus. The body is furthermore bent forward upon the cervix, so that its anterior surface rests upon the empty bladder. The angle of the normal anteflexion, according to careful measurements by Schultze, is about 48°; Fritsch says that 90° is the physiological limit. This question will be further considered under the subject of pathological anteflexions.

Ely Van de Warker makes a full and critical study of the normal movements of the unimpregnated uterus in the _N. Y. Medical Journal_, xxi. p. 337, and of the normal position and movements of the unimpregnated uterus in the _American Journal of Obstetrics_, xi. p. 314. His conclusions substantially agree with those of Schultze.

Normal Movements of the Uterus.

Strictly, the uterus can have no absolutely normal position or location, because it has a certain normal range of movements which depend to some extent upon respiration, intra-abdominal forces, and locomotion, but more especially upon the varying quantity of material in the rectum and bladder. Its normal position, then, varies within the limits of its normal movements. If the body of the uterus rest upon the bladder, it must rise as the bladder becomes distended, and, conversely, if the urine be drawn through a catheter while the woman is lying on her back, the uterus, notwithstanding the opposing influence of its own weight, immediately follows the receding wall of the bladder and returns through an angle of 45°, or possibly even 90°, to its accustomed position. The dotted lines in Fig. 2 indicate the degree of version and flexion consequent upon the varying quantity of fluid in the bladder.

{150} The full rectum forces the uterus in the opposite direction, toward the symphysis, and thereby counteracts the influence of the bladder. This anterior movement is, however, somewhat limited, and is confined to the cervical portion, except when the body has been forced back into close proximity with the rectum by the over-distended bladder.

Normal Supports of the Uterus.

The uterus is maintained in its normal position and location by the following agents:

_a_. The uterine ligaments;

_b_. The pelvic floor.[3]

[Footnote 3: For a description of the female pelvic floor see Hart's _Atlas_.]

_a_. Physiologically, these ligaments are relaxed; the state of tension would be pathological; they do not fix the uterus; they only tend to limit its movements to their normal range. Backward displacement of the body is resisted by the round ligaments, backward displacement of the cervix by the utero-vesical ligaments and by the vesico-vaginal wall. Forward and downward displacements are resisted by the utero-sacral ligaments, and excessive lateral motion by the broad ligaments. This restraining power is doubtless greater in the utero-sacral than in any of the other ligaments.

_b_. The pelvic floor, which is the chief support of the uterus, is divided into two segments, the pubic and the sacral. The pubic segment[4] is composed of bladder, urethra, anterior vaginal wall, and bladder peritoneum. It is attached in front to the symphysis pubis and laterally to the anterior bony walls of the pelvis. The sacral segment[5] is composed of rectum, perineum, posterior vaginal wall, and strong tendinous and muscular tissue. It is attached to the coccyx, to the sacrum, and to the posterior wall of the bony pelvis.

[Footnote 4: Hart and Barbour's _Manual of Gynecology_.]

[Footnote 5: _Ibid._]

Permeating the pelvic floor in all directions, entering into the composition of its single parts, binding them together, and sending its processes to the bony pelvis, is the pelvic connective tissue, upon the integrity of which depends the integrity of the pelvic floor as a uterine support. Its pernicious influence as a pathological factor will be considered hereafter. The old idea that the uterus is supported by the vaginal walls or by the perineum or by the uterine ligaments is obsolete; they are important parts of the pubic and sacral segments, and as such contribute their share, but the pelvic floor as a whole supports the uterus. The various uterine supports are to a great extent the seat of motor influence. They consequently not only resist excessive movement, but also serve to return the organ from its physiological migrations.

DEFINITION AND NOMENCLATURE OF DISPLACEMENTS.--In the foregoing pages the normal location, position, movements, and supports of the uterus have been defined. Those conditions are pathological which induce changes to positions or locations beyond the defined limits, or which so fix the organ that its normal movements are prevented. The displacements are divided into mal-locations and malpositions.

The mal-locations in which the entire uterus occupies a place outside {151} its normal limits are as follows: ascent, retro-location, ante-location, lateral location, descent.

The malpositions are determined by excessive change in the inclination of the uterine axis. They are further divided into flexions, in which the organ is bent upon itself in an abnormal degree, manner, or direction; and versions, in which the axis of the unflexed uterus inclines in an abnormal degree or direction. The malpositions are retroversion, retroflexion, lateral version, lateral flexion, anteversion, anteflexion.

SYMPTOMS AND DIAGNOSIS IN GENERAL.--Each variety of displacement may be indicated by its own group of symptoms and physical signs. These will be presented in the study of the special lesions. To avoid repetition, those symptoms and signs which pertain to no special displacement, but which belong to all alike, will be mentioned at once. They may arise either from the displacement itself or from its possible complications, of which the following are examples: Metritis, ovaritis, salpingitis, atresia and stenosis, cystitis, vesical catarrh, rectitis, rectal catarrh, peri-uterine cellulitis and peritonitis, uterine catarrh, tumors, cicatrices, etc.

Uterine displacement may be a cause or an effect of associated complications, or together with them it may be a concurrent result of some common cause, or it may have had primarily no pathological connection with them. The symptoms of displacement refer to the pelvic organs or to the nervous system. Among the symptoms which refer to the pelvic organs are--difficulty in walking and standing; pelvic pain, more or less constant; dysmenorrhoea, menorrhagia, sterility, frequent abortion, constipation, painful or difficult defecation, dysuria, polyuria, tenesmus, etc. Among the symptoms which refer to the nervous system are--neuralgia in various parts, paralysis, hysteria, nervous dyspepsia, anæmia, chlorosis, spinal irritation, etc.

The final diagnosis must always depend upon direct examination of the uterus itself. The first division of the above group of symptoms is not likely to escape notice as indicative of displacement, but the nervous symptoms are constantly disregarded or treated without reference to their possible pelvic origin. The frequent dependence of these nervous phenomena upon displacement is proved by their persistence in many cases after ordinary treatment, by their prompt disappearance upon permanent replacement and retention of the uterus by mechanical means, and by their equally prompt recurrence upon removal of the support. The presence, therefore, of the second division of the group or any part thereof, even though the first be absent, will justify, may even necessitate, a careful investigation into the state of the pelvic organs.

That examination which results only in giving the name to a special variety of displacement, and does not include the complicating lesions, would not furnish a sufficient guide to the therapeutic indications, and is therefore inadequate. The successful treatment, for instance, of an anteflexion dependent upon inflammation of the utero-sacral ligaments must include the removal of the inflammation.

An important prerequisite to examination is the absence of material in the rectum and bladder. The full rectum distorts the vaginal walls, deprives the examiner of the space necessary for the introduction of the speculum, and throws the uterus out of its accustomed position. Much more troublesome is the presence of even a small quantity of urine in {152} the bladder, because it causes the patient to render the abdominal muscles tense when the hand is placed over the lower portion of the abdomen for bimanual palpation, and makes it impossible to engage the uterus between the hand and the examining finger. The distended bladder by pushing the uterus upward and backward makes bimanual palpation almost useless. It is not surprising that conflicting opinions are common, when one day the patient is examined with rectum and bladder full, another day empty; one day in the dorsal, another in Sims's or the knee-chest position; one day with the cylindrical or bivalve speculum, another day with Sims's or Simon's.

For digital examination the dorsal position is preferred: the patient should be drawn close to the edge of a bed, or preferably a table, the thighs being flexed, the feet about fifteen inches apart, and the knees widely separated. The examiner should stand facing the patient, never at the side. The index finger of the left[6] hand, lubricated with vaseline or oil, then slowly advances over the perineum into the vagina, noting the condition of the perineum, the presence or absence of cicatrices or of sub-involution of the vagina or perineum, the capacity of the vagina, the condition, size, and direction of the cervix, its distance from the sacrum and vulva, its mobility or fixation. Now, for the first time, the right hand is pressed well down behind the pubes, and the uterus is engaged between it and the examining finger. (See Figs. 16 and 17.) In this way the examiner may determine more accurately the position, location, and size of the entire organ; may detect the possible presence of complicating tumors, both inflammatory and non-inflammatory; may also note, if possible, the location and condition of the ovaries, which, especially in the posterior displacements, are liable to be prolapsed and excessively sensitive, and to constitute, therefore, a most intractable complication. The index finger sweeps around the cervix in search of tender places which may be the result of former cellulitis or the expression of some neurosis. Above all, the digital examination requires a light, gentle, delicate touch.

[Footnote 6: The left-hand method of examination is incomparably superior to the right. The palmar surface of the index finger is more easily directed toward the left side of the pelvis, which is especially subject to disease. Its tactile sense is more acute and more easily educated. The stronger right hand should be free to palpate the surface of the abdomen in conjoined manipulation.]

In exploring the uterine cavity to learn its position the fine silver-wire probe of Emmet--not the sound--should be used. The uterus, if freely movable, is liable to be thrown out of its accustomed position by the heavier, unyielding sound. The sound also causes much more pain and exposes the patient to great danger of cellulitis. The frequent lighting and relighting of pelvic inflammation by injudicious slight manipulations of the uterus doubtless led Emmet to the utterance of a prophecy which ought to become classical: "A great advance in the treatment of the diseases of women will be made whenever practitioners become so impressed with the significance of cellulitis as to apprehend its existence in every case. The successful operator in this branch of surgery will always be on the lookout for the existence of cellulitis, and take measures to guard against its occurrence."

When the probe or the sound is used without the speculum, the patient {153} should be on the back and the index finger of the left hand should be used as a guide. The bivalve and cylindrical specula are almost useless in explorations of the interior of the uterus. The exploration is most effectually and gently made with Sims's speculum, the patient being in the left latero-prone position. In some cases the probe cannot be passed by any other method.

Ascent of the Uterus.

This mal-location may result from traction above or from pressure below. The organ may be drawn upward and backward by shortening of the utero-sacral ligaments, which results from inflammation and which usually induces a troublesome form of anteflexion. The enlarged pregnant uterus sometimes becomes attached by adhesive inflammation to a portion of the peritoneum in one of the higher zones of the pelvis or in the abdomen, and the organ may consequently remain fixed in its elevated position after involution. A tumor connected with the uterus or its appendages which has grown too large to be retained in the pelvis may, upon rising into the abdomen, drag the uterus with it. Pressure below may come from excessive distension of the rectum or bladder, or from a large accumulation of menstrual fluid in the vagina, or from a tumor originating in any portion of the pelvis below the level of the uterus. In diagnosis, prognosis, and treatment this displacement is wholly subordinate to the more significant lesions of which it is only the incidental result.

Retro-location of the Uterus.

The uterus may be forced back into a post-normal location by the presence of a tumor in front or by the distended bladder, or it may be drawn back and fixed by peritoneal adhesions. Retro-location is liable to induce vesical irritation by putting the vesico-vaginal wall on the stretch and thereby dragging on the neck of the bladder. This intractable symptom is sometimes relieved by Emmet's buttonhole operation of urethrotomy, for an account of which see section on Anteflexion. This operation would obviously be applicable also for the relief of the same symptom when caused by ascent of the uterus.

Ante-location of the Uterus.

The causes of this displacement are similar to those which produce retro-location; they are--distension of the rectum, post-uterine hæmatocele, post-uterine tumors, and peritoneal adhesions. Ante-location often causes vesical irritation, consequent upon the invasion by the uterus of that space which belongs to the bladder.

Lateral Locations of the Uterus.

The entire uterus is often displaced to the right or the left by a tumor or by an inflammatory exudate. The latter occurs as a product of {154} cellulitis, usually in the left broad ligament, and crowds the organ toward the opposite side of the pelvis. After resolution the ligament, shortened by inflammatory contraction, draws the uterus to the affected side and fixes it there. Lateral displacement from this cause often accompanies laceration of the cervix, the cellulitis having occurred on the side corresponding to the laceration.

Descent or Prolapse of the Uterus.

The nature of this displacement is clearly indicated by its name. It is convenient to distinguish three degrees of descent: In the first the organ is displaced downward and forward until sufficient space has been gained between the cervix and the sacrum to permit the body to turn back into extreme retroversion; in the second the cervix descends to the vulva; in the third the uterus protrudes partially or wholly through the vulva, constituting a condition sometimes called procidentia.

ETIOLOGY AND CLINICAL HISTORY.--Descent may be the result of any or all of the following causes: I. Pressure from above; II. Weakening of the supports; III. Increased weight of the uterus; IV. Traction from below. Either of the above conditions being the primary cause, the others singly or combined may result.

I. Pressure from above may depend upon the presence of a pelvic or abdominal tumor, ascites, fecal accumulations, tight or heavy clothing, etc.

II. The uterine supports may be weakened and relaxed in consequence of subinvolution, senile atrophy, abnormally large pelvis, increased weight of the uterus, pressure from above, traction from below, etc.

III. Increased weight of the uterus may be caused by congestion, subinvolution, hypertrophy, hyperplasia, pregnancy, fluid in the endometrium, uterine tumors, etc.

IV. Traction from below may be due to vaginal cicatrices, abnormally short vagina, falling of the pelvic floor, etc.

Obviously, descent of the vesico- and recto-vaginal walls, or, more comprehensively, the sacral and pubic segments of the pelvic floor, involves also concurrent descent of the uterus. Descent of the vagina, therefore, must be studied in connection with the descent of the uterus. Excessive descent of the vaginal walls usually originates with parturition.

In labor the anterior wall of the vagina is so depressed, stretched, and shortened by the advancing head that during and after the second stage the anterior lip of the cervix may be seen behind the urethra. If the puerperium progress favorably, with prompt involution of the uterus, vagina, perineum, and peritoneum, the relaxation of the vesico-vaginal wall and of the utero-sacral supports disappears and the uterus resumes its normal multiparous location and position.[7] But if the enlarged uterus remain in the long axis of the vagina, with its fundus incarcerated in the hollow of the sacrum between the utero-sacral ligaments, and with its sacral supports so stretched that they cannot recover their contractile power, and with involution of all the pelvic organs arrested, the descent {155} may not only persist, but may even progress with constantly increasing cystocele to the third degree of prolapse. The downward influence of the above conditions may be materially increased by rupture of the perineum, and consequent prolapse of the recto-vaginal wall into a pouch called rectocele.

[Footnote 7: The anteflexion of the multiparous uterus is less than that of the virgin.]

In the great majority of cases of complete prolapse the posterior vaginal wall in its descent is peeled off from the rectum, leaving the latter in its normal position. In rare instances the lower portion of the rectum is also found to have extruded in extreme rectocele, making a pouch below and in front of the anus, where fecal matter may accumulate and remain in hard scybalæ.

Obviously, complete prolapse of the uterus is only an incident to the prolapse of the pelvic floor. The whole mechanism is in all respects analogous to that of hernia. The extruded mass drags after it a peritoneal sac, which, hernia-like, contains small intestine. This sac forces its way to the pelvic outlet and extrudes through the vulva, having the inverted vagina for its covering.

In descent of the first degree the location of the uterus is either changed to a lower level, the position remaining normal, or, as is more common, the cervix having moved nearer to the symphysis and the organ turns back into retroversion. In a given case suppose the vaginal walls from some cause to have become relaxed and to have settled {156} to a lower level in the pelvis. As an associated fact the uterus to which these walls are attached must then also occupy a place correspondingly nearer to the vulva--_i.e._ the location of the uterus has changed, so that space enough intervenes between it and the hollow of the sacrum for the former to turn back into the position of retroversion or retroflexion. If, on the contrary, the descending uterus still maintains its normal anteversion and anteflexion, it must occupy space which belongs to the bladder. The vesical irritation consequent upon this mal-location has generally been ascribed to the anteversion and anteflexion, which are therefore oftentimes wrongly pronounced pathological. The prompt relief which follows permanent replacement of the organ in the normal location, even though in so doing its anteposition be exaggerated, proves that the symptoms depend upon the mal-location, not upon the anteposition. The importance of a clear distinction, therefore, between location and position becomes apparent. Vesical irritation, moreover, is sometimes caused by the dragging of the uterus upon the neck of the bladder. This traction occurs not only in ascent, but also when the organ descends below a certain level.

In the foregoing paragraphs traction due to the falling pelvic floor has been discussed as a cause of descent. The impairment of the uterine supports may, however, be such that instead of falling and dragging the uterus after them, they simply permit it to descend along the vaginal canal by the force of its own weight, and to carry with it the reduplicated vaginal walls. This influence is generally enforced by the increased weight of the diseased organ. The vagina more readily becomes a track for the descending uterus when from any cause the normal forward direction of the vaginal canal changes toward the vertical: this change may occur either as the result of a forward displacement of its upper extremity, involving anteposition of the cervix, or of a retro-displacement of its {157} lower extremity in consequence of rupture or subinvolution of the perineum. (See Fig. 3.) Descent in the track of the vagina is obviously combined with some degree of retroversion, because the axes of the uterus and vagina then correspond.

The PATHOLOGICAL ANATOMY may involve all the displaced organs. The circulation throughout the pelvis is impeded by traction upon the vessels, and the entire pelvic contents therefore become the subject of venous congestion, with consequences disastrous to local innervation and nutrition.

The ovaries may suffer concurrent displacement, with resulting inflammatory and cystic enlargement. The peritoneum which enters into the formation of the uterine ligaments and of the pelvic floor is dragged along with the uterus.

The vagina is hypertrophied and swollen. Its mucous membrane becomes the seat of acute vaginitis and chronic catarrh. In the third degree of descent the exposed vagina, no longer lubricated by the normal secretions of the uterus, becomes dry, parchment-like, oedematous, eroded, and ulcerated. Sometimes the cul-de-sac of Douglas is distended by downward pressure of the intestines, by a small tumor, or by ascitic fluid, and a consequent hernial sac may protrude into the vagina through some portion of the posterior vaginal fornix. The anterior fornix is subject to a similar accident. These conditions are designated enterocele vaginalis, anterior and posterior.

The rectum and bladder are subject to inflammation and chronic catarrh, and the bladder especially to concurrent descent. The uterus may be enlarged from any one or all of a variety of causes--congestion, subinvolution, hypertrophy, and hyperplasia. Its cervix is often the seat of extreme erosion or so-called ulceration. The endometrium, in order to relieve the organ of its surplus blood, gives forth an excessive secretion of mucus, which upon being increased in quantity becomes vitiated in quality. This is termed uterine catarrh. The enlargement of the uterus often pertains more to the cervix than to the body, especially in prolapse of the second and third degrees. An explanation of this may be found in Figs. 5 and 6.

Apparent elongation and disproportionate circular enlargement of the cervix are conditions which almost every standard author wrongly calls hypertrophic elongation and circular hypertrophy. The question of elongation is easily settled by placing the patient in the knee-chest position. Then the uterus by its own weight falls toward the diaphragm, the vagina unfolds, and the apparent utero-vaginal attachment _X'_ _Z'_ (Figs. 5 and 6) disappears, disclosing the actual attachment, _X_ _Z_. Further, the point of the sound, passed into the bladder while the {158} cervix is exposed by Sims's speculum, may be placed against the anterior wall of the cervix at _Z_, which would be impossible if the attachment were at _Z'_.

The comparatively small amount of hypertrophy in disproportionate circular enlargement is proved by the operation of trachelorraphy or by bringing the points _a_ and _b_ (Fig. 6) together with uterine tenacula, the organ being exposed by Sims's speculum. Then the out-rolled intracervical mucous tissues are rolled back, the proper diameter of the cervix is restored, and a laceration on one or both sides, extending past the vaginal attachment, becomes apparent.

Hypertrophy or hyperplasia usually causes a nearly symmetrical enlargement of the entire organ. At any rate, those cases in which the reduplication of the vaginal walls does not almost entirely explain the great elongation so called, or in which great disproportionate circular enlargement has not been caused by laceration of the cervix, are the rare exceptions. The great merit of having secured general assent to the foregoing proposition, and of having given to the subject a new and right direction, must be accorded to Emmet. The cervix now is seldom amputated except for malignant disease.

Congestion of the uterus consequent upon obstruction in the stretched and displaced veins is often so extreme as to induce a state analogous to erection. Measurements by the probe just before and a few minutes after replacement generally show an appreciable decrease in the length of the uterine canal. If the prolapse has been of the third degree, the difference may amount to one or even two inches. It is important not to confound the enlargement of congestion with increase in the solid constituents of the organ.

SYMPTOMS AND COURSE.--A dragging sensation and pelvic and abdominal pain are generally present. Rectocele and cystocele and rectal and vesical catarrh often cause painful and severe functional disturbances of the rectum and bladder. In descent of the third degree excoriations of the exposed vagina and cervix sometimes cause extreme suffering. The course is ordinarily chronic, but attacks of acute vaginitis and pelvic peritonitis are not uncommon. The peritonitis sometimes effects a spontaneous cure by peritoneal adhesions which fasten the uterus in an elevated position and hold it permanently. The symptoms of descent may be so severe as to necessitate absolute rest in bed. In other cases they are often attended with very little discomfort.

{159} DIAGNOSIS is by inspection, palpation, and exploration. The prolapsed uterus may be distinguished from cystocele, rectocele, inverted uterus, and fibroid tumor by the presence of the os externum. The sound may be passed through the urethra into the cystocele, and the finger through the anus into the rectocele. The length of the uterus may be determined by the sound, the size, shape, position, extent of descent, and difficulty of replacement by conjoined manipulation.

PROPHYLAXIS.--This requires such measures during labor as may be necessary to prevent long and powerful pressure upon the pelvic floor. After labor any injury to the perineum should be promptly repaired. The vagina should be kept clean by irrigations. The urine, if necessary, should be regularly drawn and the bowels moved daily without straining. If conditions be present likely to induce subinvolution--such, for example, as pelvic inflammation or laceration of the cervix--they should receive treatment at the proper time. Undue relaxation of the pelvic floor necessitates a more prolonged rest in bed, the use of astringent douches, and the application of a pessary when the patient resumes the upright position.

TREATMENT.--The first indication is replacement, which in the first and second degree of descent is not difficult unless the uterus be held down by cicatrices or by a tumor. Complicating pelvic cellulitis and peritonitis may render replacement dangerous or impossible, and may for a time contraindicate all direct treatment. Replacement of the organs from the third degree of prolapse is accomplished in the inverse order of their descent: first, the posterior vaginal wall, then the uterus, and last the anterior vaginal wall. Not infrequently the completely prolapsed uterus and pelvic floor, hernia-like, become strangulated. Then taxis will usually suffice if supplemented by hot applications, elastic pressure, anodynes, and the knee-chest position. Should these fail anæsthesia may be required.

Undue pressure from above should if possible be removed. The clothing should be loose, and the weight of the skirts supported from the shoulders either by straps or preferably by buttoning them upon a waist made for the purpose. This waist is a good substitute for the corset, which under all circumstances and in all its forms is injurious. Increased uterine weight from subinvolution or congestion is to be overcome by appropriate means. Enlargement of the uterus when due to hypertrophy or hyperplasia is generally incurable. Amputation of the cervix for what was formerly considered circular hypertrophy and hypertrophic elongation is now seldom or never required for the purpose of decreasing uterine weight. Amputation except for malignant disease has given place to the operation of trachelorraphy. Tumors exerting pressure above or traction below should if possible be removed. Regulation of the bowels and general tonics are usually necessary. The knee-chest position assumed several times a day causes the uterus to gravitate toward the diaphragm, and thereby gives temporary rest to the overburdened supports. While in this position the patient should separate the labia, so that the air may rush in and the vagina become expanded. The measures enumerated above, together with rigid care of the diet and of such other hygienic requirements as the individual case may demand, are essential as adjuvants to the more special treatment which almost every case requires.

{160} In exceptional cases of sudden descent, even to the third degree, replacement alone is sometimes followed by permanent relief; but if the descent has been gradual it always recurs immediately after replacement. Measures are therefore required for the maintenance of the uterus in its normal location and position. This indication is fulfilled by pessaries and by operations.

Pessaries.--The function of the pessary is not only to maintain the uterus on the health level in its normal location, but also, if possible, in its normal position, which requires the cervix to be about one inch from the sacrum. The cervix being thus placed, the organ cannot turn back into retroversion, because in so doing the fundus would encounter the sacrum. The direction of least resistance would then be forward into the normal anterior position. The application of the pessary is then based upon the general proposition that if the cervix be normally placed the body of the uterus will in the absence of complications take care of itself. Since the vagina at its upper extremity is attached to the cervix, displacement of the latter is clearly impossible if the upper extremity of the vagina be sustained in its normal location. The pessary restores and maintains the relations of the relaxed vaginal walls by crowding the posterior vaginal cul-de-sac backward into the hollow of the sacrum. It thereby also holds the attached cervix within a proper distance of the sacrum. The Hodge pessary or some modifications thereof fulfils this purpose in ordinary cases more satisfactorily than any other.

The curves of the pessary demand careful attention in its application. When the uterus is below the normal level, the broad ligaments are necessarily rendered more tense than natural, and the blood-vessels, more especially the veins, which are looped one upon the other, and which traverse these ligaments to and from the uterus, are made to collapse. This causes venous congestion and consequent increase in weight of the uterus--a condition favorable to malposition, uterine catarrh, and pathological changes in structure. A pessary which will raise the uterus to the health level clearly fulfils an indication. A pessary which raises it above the health level renders the broad ligaments tense and reproduces a condition which it was designed to relieve. Maintenance of the uterus upon the health level depends largely upon the curves of the pessary. The accompanying cuts illustrate the shape and curve of the Hodge pessary as modified by Emmet and Albert Smith. Fig. 7 represents the curve of Emmet, and Fig. 8 that of Albert Smith. For convenience let us characterize that curve which rests in the posterior vaginal cul-de-sac as the uterine curve, and that which occupies that part of the vagina {161} adjacent to the pubis the pubic curve. The acuteness and length of the uterine curve determine the height to which the pessary will lift the uterus. The longer and more acute the curve, the higher the uterus will be lifted, and vice versâ. The smaller curve of the Emmet modification will answer the average indication more nearly than the sharper curve of the Albert Smith modification, which may lift the uterus too high. The pubic should generally be proportioned to the uterine curve; that is, the greater the uterine, the greater the pubic curve. A pessary properly adjusted in all other respects may, by pressure upon the urethra and neck of the bladder, create vesical tenesmus and urethral irritation. This calls for increase in the pubic curve. The pubic curve may, however, be so great that the lower part of the pessary occupies the centre of the vulva, where it may create irritation. For this condition lessening of the pubic curve is the remedy. The pessary should not be so wide as to distend the vagina. Its length should be measured by the distance from the lower extremity of the symphysis pubis to the posterior vaginal cul-de-sac, less the thickness of the finger. If properly adjusted it should sustain the pelvic floor in its normal relations and the uterus in stable equilibrium.

The uterus in the first and second degrees of descent is usually either retroverted or retroflexed. The reader is therefore referred to the remarks on the application of pessaries in the treatment of these displacements.

In advance prolapse dependent upon extensive injuries to the perineum and other parts of the pelvic floor, and usually associated with extreme subinvolution of all the pelvic organs, the axis of the vagina is often changed from its forward oblique to the vertical direction. (See Fig. 3.) The downward traction of the prolapsing cystocele and rectocele upon the fornix of the vagina may then be so great that the pessary is inadequate to maintain in place the upper extremity of the vagina. The cervix then moves forward, the corpus turns back, and the whole uterus easily descends in a vertical direction along the prolapsing walls of the vagina to the second or third degree of prolapse. In this condition pessaries which disappear within the vagina are liable to be forced out with the prolapsing pelvic floor, or if retained seldom maintain the uterus in position. In such cases the various cup pessaries which are supplied with external attachments and abdominal belts are often used, but they are inadequate, because they either so fix the uterus as to prevent its normal movements, or they hold it in such unstable equilibrium that it may assume any one of the various malpositions, anterior, posterior, or lateral; and they are open to the further serious objection of constantly reminding the patient of their presence. As an expedient the uterus may sometimes be held within the pelvis by means of a large Albert Smith pessary with extreme uterine and pubic curves. The rational treatment, however, requires first an operation on the anterior vaginal wall to restore the fornix of the vagina to its normal place in the hollow of the sacrum, and with it the attached cervix; and second, an operation at the vaginal outlet to bring the posterior wall in contact with the anterior, and thereby to restore the lower extremity of the vagina to its normal place under the pubis.

ANTERIOR ELYTRORRHAPHY.--Numerous operations on the vaginal {162} walls have been devised for the purpose of narrowing the vagina, and thus preventing descent along the vaginal canal, but they are temporary in their results, because, as long as the direction of the vagina remains vertical, its walls again become dilated by the prolapsing uterus and the former condition is re-established. The operation to be effective is performed as follows: A Sims's speculum of long blade, perforated at its extreme end, to which the cervix has been attached by a piece of silver wire, passing through the perforation and the posterior lip, is introduced, the patient being in Sims's position. The cervix is thereby drawn by the point of the speculum far back into the hollow of the sacrum. The author finds this preferable to the method described by Emmet, who has the cervix held back by a sponge probang in the hand of an assistant. The space in the anterior part of the pelvis is now so increased that the uterus readily falls forward into decided anteversion. While the uterus is thus held in position by its attachment to the blade of the speculum, the operator with two uterine tenacula finds in the loose vaginal tissue on either side of the cervix two points which can be brought together in front of the cervix. Then at each of the two lateral points a surface is denuded with the curved scissors about one-half inch square, and in front of the cervix a surface an inch long by half an inch wide across the anterior vaginal wall close to the uterine attachment. A No. 26 silver-wire suture is then passed, as shown in Fig. 9, and twisted as shown in Fig. 10, so as to secure the lateral denuded surfaces in contact with the larger surface in front of the cervix.

Inasmuch as the operation often fails at the point of the first suture, the author has usually introduced two or three of this kind instead of one. Two longitudinal folds are now formed on the anterior vaginal wall, which serve as guides for denuding and turning in the remaining redundant tissue by a line of sutures, which should extend forward along the centre of the vesico-vaginal wall until the folds are lost in the vaginal surface near the neck of the bladder. Sometimes the redundant tissue about the urethra cannot be disposed of by turning it in from side to side. Then it is desirable to make a crescentic denudation across the lower portion of the vagina, its concavity being on the uterine side, and {163} to unite the margins below to those above by means of a curved line of sutures. The completed operation is shown in Fig. 11.

The after-treatment requires the self-retaining Sims's sigmoid catheter in the urethra for a week or frequent catheterization, absolute rest in bed, hot-water vaginal douches, regulation of the bowels, and the removal of the sutures on the twelfth day. After the completion of the operation the cervix is maintained near the hollow of the sacrum, and the organ remains normally anteverted and anteflexed, making an acute angle with the vesico-vaginal wall, which has now been restored to its normal direction and length. Unfortunately, it is not unusual to abandon the patient after this operation, in the vain hope that the uterus and anterior vaginal wall will maintain their normal relations without the support of the perineum and posterior vaginal wall. This is a great mistake, because the cystocele and procidentia almost always completely reappear within a few months. Anterior elytrorrhaphy, therefore, is simply one of the steps in the treatment.

PERINEORRHAPHY.--This is the name usually applied to the repair of the ruptured perineum, but the scope of the operation has been extended to include also the surgical treatment of rectocele and relaxation of the posterior vaginal wall. The most scientific operation yet devised is the one proposed by Emmet,[8] which is performed as follows: The patient being etherized and in the lithotomy position, the operator seizes with a tenaculum the crest of the rectocele or posterior vaginal wall at a point which can be drawn forward without undue traction--point _a_. With another tenaculum the lowest caruncle or vestige of the hymen (point _b_), {164} and with another the posterior commissure of the vulva (point _c_), are hooked up. The triangle included between these points defines one-half of the surface to be denuded. The three tenacula are now placed in the hands of assistants, the sides of the triangle are made tense by traction, and the included surface denuded. The tenaculum at _c_ is then removed, and the middle point of the line _a b_ is caught and drawn toward the interior of the vagina in the direction of the vaginal sulcus on that side, and the sutures are introduced, as in Fig. 13. The same thing is then repeated on the other side, and the sutures are all tightened, forming a line of union running back into each sulcus, as shown in Fig. 14.

[Footnote 8: _Trans. Am. Gynæcological Society_, 1883; _Principles and Practice of Gynecology_, 3d ed.]

The essential part of the operation inside the vagina almost always succeeds, but the external part of the rupture at the posterior commissure often fails to unite; furthermore, the operation as described by Emmet does not overcome the patulous condition of the introitus vaginæ in case of great relaxation of the vagina. The author has sought to obviate the first of these difficulties by the use of deep silver sutures instead of the superficial ones described by Emmet. They should be introduced before tightening the vaginal sutures, and should be passed far around in the posterior vaginal wall, their points of entrance and exit being the same as for the three lower unsecured superficial external sutures in Fig. 14. The second difficulty may be overcome by further denuding a triangular surface in the vaginal sulcus on each side, the base of the triangle corresponding {165} to the line _a b_, Fig. 12, and its apex being in the vaginal sulcus at a distance corresponding to the degree of relaxation. This increases the length of the lines of union running into the sulci represented by _d b_ and _e f_, Fig. 14. In the vaginal portion of the wound silk or catgut is preferable to silver, the latter being difficult to remove.

Emmet is entitled to great credit for having given to the profession an operation which brings the posterior vaginal walls up against the anterior more perfectly than any other, and which, being mostly inside of the vagina, is therefore followed by very little of the pain during convalescence which formerly rendered perineorrhaphy one of the most trying operations in gynecology. The operation furthermore has demonstrated the former teachings relative to the direction of perineal rupture[9] and the tissues involved to be incorrect, or at least inadequate.

[Footnote 9: At the meeting of the American Medical Association in June, 1883, the author presented a paper describing the transverse laceration of the perineum and its operative treatment, which was published with illustrations in the transactions by the journal of the Association, Dec. 22, 1883. This communication referred only to the recent rupture and the immediate operation.]

Retroversion.

Retroversion is that position of the uterus in which the fundus is posterior to the axis of the pelvic inlet. If the cervix be in its normal place near the sacrum, retroversion is scarcely possible, because it is prevented by the proximity of the over-arching sacrum. (See Fig. 2.) The first degree of prolapse must therefore precede any considerable backward turning of the uterus. When the cervix has been displaced downward {166} and forward so far that its distance from the sacrum is equal to or greater than the length of the uterus, retroversion to any extent becomes possible. (See Figs. 3 and 16.)

ETIOLOGY AND HISTORY.--From the above it follows that the causes of commencing retroversion must be identical with the causes of the first degree of prolapse. After the puerperium the relaxation of the supports and the weight of the organ may persist, and spontaneous replacement may be prevented by the pressure and weight of the intestines upon the anterior surface. Every act of defecation forces the cervix forward and downward, and the uterus, being in the axis of the vagina, and having therefore little support below, must depend upon the subinvoluted peritoneal suspensory ligaments and pelvic fascia, which are inadequate. This condition is very often induced by abortions, with resulting increased weight and relaxation of the vaginal walls. Local peritonitis and cellulitis may permanently fix the corpus in its retroverted position by cicatricial bands and adhesions.

SYMPTOMS AND COURSE.--The displacement and its complications usually cause bearing-down sensations, a feeling of heaviness in the pelvis, exhaustion upon walking and standing, especially the latter, and constipation. After the puerperium the extreme engorgement of the pelvic organs often produces uterine hemorrhage, which should not be confounded with the returning menstruation. Especially after abortion the hemorrhage often persists for a long time unless cured by treatment. Gradual or sudden replacement may occur spontaneously, or the causes may continue active, and even be enforced by cystocele and rectocele. The displacement may also be complicated by disease and displacement of the ovaries. Organic disease of the uterine walls may induce a superadded retroflexion. The heavy organ may descend along the relaxed subinvoluted vaginal walls even to complete procidentia.

DIAGNOSIS AND PROGNOSIS.--The symptoms outlined in the preceding paragraph indicate the probability of displacement, but the diagnosis depends upon direct examination of the uterus. Conjoined manipulation and the probe will usually show the retroverted organ with the cervix displaced toward the pubes and with the corpus in the hollow of the sacrum. The introduction of the probe is contraindicated by cellulitis and peritonitis. In certain cases of anteflexion, as represented in Fig. 23, the cervix is bent forward in the vaginal axis as in retroversion. The condition is in reality one of retroversion of the cervix with high anteflexion of the corpus, which may usually be detected by careful conjoined examination. The prognosis with treatment is generally favorable both for speedy relief and ultimate recovery.

TREATMENT.--As in descent, the treatment consists in removing cellulitis, peritonitis, and other complications, in the use of pessaries, and in operations on the anterior and posterior vaginal walls if needed. Inasmuch as the treatment corresponds to that of retroflexion, it will be presented under that subject.

Retroflexion.

ETIOLOGY AND PATHOLOGY.--Retroflexion is that displacement in which the organ is bent backward upon itself. It usually results from, {167} and is associated with, retroversion, but for convenience the double displacement will be termed retroflexion. It may be caused by the great weight of the corpus, the soft flexible state of the uterine walls during and after involution, intra-abdominal forces, downward pressure during defecation, tight clothing, and not commonly by the obstetric bandage.

The ovaries, unless fixed elsewhere by adhesions, are displaced with, and held down on either side of, the corpus, sometimes enlarged from inflammation, often adherent, and always extremely sensitive. Chronic metritis, cellulitis, and peritonitis, with adhesions more or less firm, are usually present, and not infrequently as the result of gonorrhoea, abortion, or injudicious treatment. Peritoneal adhesions between the corpus and the cul-de-sac of Douglas sometimes make replacement impossible. In rare cases the displacement is congenital.

SYMPTOMS AND COURSE.--Among the most pronounced symptoms are profuse uterine catarrh, menstrual disorders, sterility, abortion, weakness, pain in the back, painful defecation, rectal tenesmus, the symptoms of pelvic inflammation, neurasthenia, and other nervous symptoms. The uterine catarrh is due to an effort on the part of the engorged pelvic organs to relieve themselves by an exaggerated secretion of mucus from the uterus, which upon being increased in quantity becomes vitiated in quality, and therefore pathological. Menorrhagia and abortion may also result from congestion. Dysmenorrhoea and sterility result from the {168} general anæmic condition and from the inflammatory complications, and from the obstruction in the uterine canal or in the blood-vessels at the angle of flexure. (See Pathology of Anteflexion.) The rectal symptoms are caused by the pressure of the corpus uteri upon the rectum, which gives the sensation to the patient of an overloaded bowel.

Should pregnancy occur, the rapid growth of the uterus may induce spontaneous reposition at about the fourth month, when the fundus rises out of the pelvis, but if the corpus be incarcerated under the sacral promontory from adhesions or from any other cause, the uterus will, unless manually replaced, relieve itself by abortion.

Abdominal pains, nervous dyspepsia, and neuralgia in distant parts of the body are often present; indeed, the nervous symptoms may be of the most exaggerated character, and may comprise all that is implied by the word hysteria in its most comprehensive signification.

DIAGNOSIS.--Digital touch discloses the cervix low in the pelvis, and the fundus uteri is felt through the posterior vaginal wall in the cul-de-sac of Douglas. Conjoined manipulation with the index finger of the left hand, first in the vagina and then in the rectum, and the right hand over the hypogastric region, will show the size, form, consistency, and location of the uterus, the degree of the flexure, and the difficulty of replacement. An inflammatory exudate or hæmatocele, posterior to the uterus, or a fibroid in the posterior uterine wall, may be mistaken for the retroflexed corpus. The probe will always verify the diagnosis, but if there be great tenderness with fixation in the cul-de-sac of Douglas, treatment should be directed against the inflamed condition, and the final diagnosis made by repeated examinations or after the disappearance of the inflammation. Great and lasting injury is often done in the attempt to complete the diagnosis at the first examination. The presence of a fibroid in the posterior uterine wall with post-uterine inflammation is a serious complication both in diagnosis and treatment. If the rectum be overloaded with fecal matter, the diagnosis should be deferred. The displacement is distinguished from the presence of an ovary or small ovarian tumor in the pouch of Douglas by careful bimanual examination and by the probe.

TREATMENT OF RETROVERSION AND RETROFLEXION.--The objects of treatment are replacement and retention of the uterus. The obstacles to replacement are cellulitis, peritonitis, and fixation of the uterus, and these complications often require weeks, and in severe cases months, of treatment preparatory to replacement. Some of the general therapeutic suggestions under the subject of descent are also applicable to the retro-positions. Rest, massage, careful regulation of the bowels, feeding, and general tonics are essential. For the inflammation small blisters over the inguinal regions frequently repeated, and the daily application of the cotton and glycerin plug to the cervix, and dry cupping over the sacrum, are most efficacious. The glycerin may be combined with alum, tannin, chloral hydrate, or iodoform. Thymoline in small quantities partially destroys the disagreeable iodoform odor. The most useful and essential topical application is the hot-water vaginal douche, but its use will be followed by failure and disappointment if it be applied in the ordinary way. The following is quoted from a paper by the author which was published in the _Chicago Medical Gazette_, Jan. 1, 1880: {169}

"A satisfactory substitute for the bed-pan may be made as follows: Place two chairs at the side of an ordinary bed with space enough between them to admit a bucket; place a large pillow at the extreme side of the bed nearest the chairs; spread an ordinary rubber sheet over the pillow, so that one end of the sheet may fall into the bucket below in the form of a trough. The douche may then be given with the patient's hips drawn well out over the edge of the bed and resting on the pillow, and with one foot on each chair; the water will then find its way along the rubber trough into the bucket below." The Davidson syringe, which has an interrupted current, is preferable to any of the fountain syringes.
