The time for getting up should be determined by the results of treatment; usually a period of from four to six weeks is sufficient to determine whether or not the treatment at absolute rest is going to be of benefit. Of course it is not to be understood that cure will follow in severe and long-standing cases within this period, because if this hope is entertained disappointment will follow nearly always. What we hope and expect to attain is rest, both physical and physiological, during which time local treatment can be carried out with greater facility and thoroughness and the general condition improved. As a rule, the ligaments soften, the false membranes become attenuated, and during the time stated the patient is very much benefited, and sometimes cured. She should now begin to sit up and to exercise moderately; the amount of exercise should be regulated by its effect. If pain follows walking or riding, it should not be persisted in until such time as exercise can be taken without the production of these symptoms.

There are no specific remedies for internal administration. The general medication of the patient should consist in the use of such remedies as we have learned to depend upon as capable of building up the blood and nervous system, embracing especially that class of tonics which are said to have the power of inducing such changes in plastic material as favors its absorption. To this class belong the chlorides, as the chloride of arsenic, the chloride of iron, the chloride of ammonium, and the bichloride of mercury. These remedies should be placed at the head of the class. The next are the iodides, as the iodide of iron, the iodide of potassium, and the bromide of potassium. Whether or not these remedies have the powers ascribed to them is questionable, and their administration for this purpose must always be, to a certain extent, empirical. As tonic remedies the administration of iron and the bichloride of mercury is of course always indicated. Cod-liver oil is also a remedy of much value in some cases where it can be digested. The whole plan of treatment should rather be of a local than of a general character, while at the same time very great importance should be given to the building up of the general system, without which nothing can be gained by local treatment. The patient should have a change of scene and air as soon as practicable. A sojourn at the seaside for a time, and then in the mountains, will be of great benefit always.

The fact should always be borne in mind by the physician and impressed upon the patient that a previous attack of perimetritis will serve as a predisposing and abiding cause for a recurrence of the disease, so that all exciting causes may be avoided as far as possible.

PELVIC HEMATOCELE.

BY T. GAILLARD THOMAS, M. D.

HISTORY.-Prior to the present century the pathological condition which we are about to investigate had no place in the category of diseases peculiar to the sexual organs of the female. Very slowly have its pathogenic features, its etiology, and its importance as a not uncommon factor in pelvic disorders, assumed a systematic basis, and even now considerable diversity of opinion exists upon these points. The reasons for this are not far to seek. In the first place, hæmatocele is a symptom of an accident occurring in the pelvis and resulting in hemorrhage; in the second, the source of the flow which creates the hæmatoma or tumor of blood cannot ordinarily be recognized by any diagnostic measures known to science; and in the third, death rarely occurring from the accident and as a direct consequence of it, autopsic evidence is wanting upon which to base accurate and scientific data.

Although these statements are undoubtedly true, it may nevertheless be asserted with confidence that we are to-day no longer in the dark as to the general pathology of this interesting disorder, and that we are in position to map out a plan of treatment which meets the indications which present themselves in an intelligent and reliable manner. There are, however, several sources of hemorrhage which result in pelvic hæmatocele, and it is highly probable that the day will never come when that one which has created the accident can be ascertained with certainty. But while such accuracy of diagnosis would be gratifying to the ambition of the modern. diagnostician, neither the prognosis nor treatment of the disorder would be influenced by it.

Long before our day practitioners had recognized by touch the occasional presence of tumors, more or less marked by fluctuation, which occupied the pouch of Douglas, and by their mechanical influence pushed the uterus out of its normal place; but it was not until the early part of our century that it was discovered that these tumors were sometimes, and that not rarely, composed entirely of coagulated blood; and, curious though it may appear, it was not until the year 1850 that pelvic hæmatocele became a well-recognized disorder.

As early as 1737, Ruysch of Amsterdam appears to have come to the verge of discovering it, but it was left for Récamier, to whom gynecology owes so much besides, to make it known when in 1831 he opened a postuterine tumor, gave vent to a large accumulation of coagulated blood, and described the case in the Lancette Française for that year. In 1850 the

subject attracted the attention of Nélaton, became a recognized pathological condition, and has since received a great deal of attention in all the civilized countries of the world.

DEFINITION AND SYNONYMS.-Pelvic hæmatocele-which has likewise received the names of retro-uterine hæmatocele and uterine hæmatoma-may be defined as an effusion of blood into the pelvic cavity of the female, either into or under the peritoneum. Some authors have limited this definition to blood escaping from utero-ovarian vessels and to blood enclosed either by anatomical structures or by previously-existing inflammatory products. I do not adopt these restrictions, because their assumption appears to me to be unwarranted and the validity of the reasons given for their adoption more than doubtful. The location of the blood-mass differs widely in different cases: sometimes, and usually, it is behind the uterus-high up when obliteration of Douglas's pouch has occurred, low down and near to the perineum where such obliteration has not occurred; at other times it exists both behind and in front of the uterus; and at others still, in front of the uterus alone, adhesions preventing its percolation to the posterior parts of the pelvis.

FREQUENCY.-It may be said, in general terms, that this affection is by no means rare, every one of large experience in gynecology meeting necessarily with a large number of cases of it. But no reliable statistics of its frequency have been collected up to the present time. Olshausen of Halle declares that in 1145 gynecological cases he saw 34 hæmatoceles; Beigel in 2000 cases found 38; Schroeder, 7 in 1000; and Seiffert of Prague reports 66 seen in 1272 cases of female pelvic diseases. Barnes says that in ten years' practice he met with 53 cases, and in twenty years Tilt has seen but 12.

Without doubt, the validity of the statistics of this disorder is vitiated by erroneous diagnosis, as is the case with all affections which generally end in recovery. Here cases of cellulitis, pelvic peritonitis, imprisoned cysts, etc. offer prolific sources of error, as I can aver from the results of my own experience.

PATHOLOGY.-It is a fact, thoroughly proved by physiological experiment, that blood injected into serous cavities very soon encysts itself by the enveloping influence of lymph which is poured over it, forming false membranes, or, as the French term them, néo-membranes. The clot, once formed, clings to the serous membrane in contact with it, and soon becomes roofed over by lymph, which, according to Vulpian, begins to show traces of organization as early as the end of twenty-four hours. Should the effused blood be poor in fibrin, the coagulation and encysting do not occur, a rapid absorption taking the place of these processes.

Pelvic hæmatocele consists, as has been already stated, in the collection of a mass of blood in the pelvis, either above or below its roof, without reference to the source of the flow. Such a flow ordinarily occurs from one of the three following sources: first, rupture of vessels in the pelvis; second, reflux of blood from the uterus or tubes; third, transudation of blood in consequence of dyscrasia or pelvic peritonitis.

From this it becomes evident that hæmatocele is not a disease, but a symptom which marks a number of different pathological conditions of quite various significance. As, however, we cannot discover the original accident or pathological condition, we are forced to compromise with

taking its most prominent sign as the exponent of a state which is beyond the powers of diagnosis.

Autopsic evidence has revealed the following as the special and most frequent sources of the hemorrhage:

1st. Rupture of blood-vessels in the pelvis:

Utero-ovarian;

It is then clear that the mere presence of a large clot of blood in the pelvis, apart from general symptoms, is a matter of very doubtful significance, since on the one hand it may be the result of a mere regurgitation of menstrual blood due to imperviousness of the cervical or tubal canal, or on the other of the rupture of a Fallopian tube which has become the nidus of an extra-uterine foetus.

Whatever be the source of the blood which escapes, it coagulates, unless very poor in fibrin, either in the most dependent part of the peritoneum or in the pelvic areolar tissue beneath it. Here the watery portions of the mass are gradually absorbed, leaving a hard, small tumor remaining; or, suppurative action being excited, the hard mass is softened down and discharged into the rectum, vagina, bladder, or peritoneum as a grumous material somewhat resembling currant-jelly in appearance.

CAUSES.-These must be divided into predisposing and exciting, for it is rare to meet with the disease in a woman who has previously been in perfect health. The predisposing causes which can be cited with confidence are the period of ovarian activity (fifteen to forty-five years); disordered blood-state, plethora or anæmia; the menstrual epoch; chronic ovarian or tubal disease; pelvic peritonitis; and the hemorrhagic diathesis. The exciting causes have been found to be sudden checking of the menstrual flow; blows or falls; excessive or intemperate coition; obstruction of cervical canal; obstruction of Fallopian tubes; violent efforts; and ectopic gestation.

VARIETIES.-The two great classes of the affection are the peritoneal and the subperitoneal. In the former the blood collects in the peritoneal cavity and becomes encysted there; in the latter it collects in the cellular tissue beneath the peritoneum, and there forms a solid mass.

Some authors have opposed the consideration of these two varieties under the same head; among them, Aran, Bernutz, and Voisin. But from a clinical standpoint such a consideration appears to me to be valid. Not only have distinct instances of subperitoneal hæmatocele been recorded by such observers as Barnes, Simpson, Olshausen, and Tuck well, but

VOL. IV.-16

cases have been met with in which the subperitoneal variety has ruptured the peritoneal roof of the pelvis, and thus broken down the theoretical barrier which pathologists have been inclined to establish between the two varieties.

Of the two varieties, there can be no doubt that the peritoneal is that which presents itself the more frequently. In 41 autopsies Tuckwell found the tumor to be peritoneal in 38.

SYMPTOMS. As a rule, long before the occurrence of pelvic hemorrhage the patient will have complained of more or less decided symptoms of disease, or at least of disorder, of the genital system. The symptoms which mark blood-dyscrasia or pelvic peritonitis or menstrual irregularity will probably have attracted attention.

When the accident occurs the gravity of the symptoms will depend in great degree upon the character of the lesion which has taken place. Sometimes the blood-accumulation takes place so insidiously that the existence of the tumor created by coagulation takes the practitioner by surprise. At other times what Barnes has called a cataclysm occurs, and in a few hours puts the unfortunate patient beyond the sphere of hope or the resources of art.

In portraying the symptoms of this affection a writer can therefore merely approximate the truth, satisfying himself with the description of a case of ordinary severity, avoiding the description of cases in either extreme, and guarding the reader against supposing that all attacks give the same intensity of symptoms.

Most prominent among the immediate symptoms are severe and sudden pelvic pain; pallor, faintness, and coldness of the extremities; a sense of exhaustion; nausea and vomiting; metrorrhagia; uterine tenesmus; enlargement of the abdomen; interference with the bladder and rectum; small and rapid pulse; subnormal temperature.

These are the symptoms of invasion, those which may be termed immediate, and which depend upon loss of blood and a sudden traumatic influence exerted upon living tissues. Very soon, generally within forty-eight hours, a reaction occurs which is sometimes slight, and at other times decided. The secondary symptoms are usually the following tendency to chilliness; constipation; suppression of urine; tympanites; high temperature; rapid pulse; and tenderness over abdo

men.

These symptoms are due to a combination of two causes-loss of vital fluid and the invasion of the peritoneum or pelvic areolar tissue by a mass of blood which becomes coagulated and irritant, on the one hand, and inflammatory processes resulting from such invasion on the other. Half of them might be produced by metrorrhagia, and half by sudden and complete retroversion; but a union of the whole will point toward hæmatocele and prompt a physical examination.

PHYSICAL SIGNS.-A tumor will be felt by vaginal touch, usually, though not always, posterior to the uterus and vagina, and partially occluding the latter. This will, if the examination be made very early, be found to be soft and obscurely fluctuating, but it soon becomes a smooth, dense, and solid body. The uterus is very generally found pressed upward and forward, so that the body lies against the abdominal wall and the cervix is on a level with or a little above the symphysis
