CHAPTER VI
ON THE RELATIVE VALUE OF TOTAL AND SUBTOTAL HYSTERECTOMY
The great success which followed the use of the short ligature in ovariotomy induced several surgeons to apply the same principle to the cervical pedicle when removing the uterus for fibroids. The result was dismal failure. Matters improved somewhat after Koeberlé introduced the serre-nœud, and this continued the safest method until 1892. In the meantime antisepsis had begun to take effect in pelvic surgery, and attempts were made by Bardenheuer (1881), Polk, and other surgeons to avoid the dangerous difficulties connected with the treatment of the stump by removing the cervix as well as the uterus (total hysterectomy), and they attained an encouraging measure of success. Nevertheless, other surgeons (Goffe, Milton, Heywood Smith, and Stimson) felt that the enucleation of the cervix was not always necessary, and sought to find a way of avoiding it. The credit of solving this difficulty fell to Baer of Philadelphia (1892), for he showed that it is dangerous to constrict the neck of the uterus with ligatures, it is only necessary to secure the arteries.
Baer’s method of supravaginal hysterectomy, or, as it is now commonly termed, the subtotal operation, soon supplanted the total method of Bardenheuer. The publication of Baer’s paper had great consequences; it came at a time when the attention of gynæcologists was centred on improvements in hysterectomy. The method was promptly tested and adopted in London. The effects of this improvement in technique in a few years revolutionized the surgical treatment of uterine fibroids, as the statistical results set forth on p. 44 amply prove.
The great advantage of Baer’s method is its simplicity and safety; but there is a disposition on the part of a few surgeons to prefer the total operation, mainly on the ground that the cervical stump left after subtotal hysterectomy is liable to become attacked by cancer.
As far as I can ascertain, Dr. M. Mann, of Buffalo, was the first to draw attention to the occurrence of cancer in the neck of the uterus after the body of the organ had been removed. He stated in 1893 that he ‘removed an ovarian tumour and the body of the uterus, by accident, along with it; the cervix was left’. The patient recovered. ‘Six months afterwards cancer developed in the cervix, from which she died.’
When cases of cancer supposed to arise in the stump left after subtotal hysterectomy come to be critically analysed, they fall into four groups:--
1. The disease existed in the neck of the uterus at the time of the primary operation, but was overlooked. 2. Cancer attacked the cervical stump subsequent to subtotal hysterectomy. 3. The fibroid which necessitated the hysterectomy was really a sarcomatous tumour of the uterus. 4. The suspected growth on the cervix is not malignant, but a granuloma.
Each of these postulates requires separate consideration.
Many observations have been published which show beyond dispute that surgeons have performed subtotal hysterectomy in ignorance that the cervix was already cancerous, and the hæmorrhages of which the patients complained before the operation were due as much to the cancer in the neck of the uterus as to the fibroids. This should serve as a warning that, in cases where the surgeon contemplates performing a subtotal hysterectomy, he should carefully examine the cervix beforehand; at the time of the operation he should also critically examine the cut surface of the cervix, and if it be in the least suspicious he should remove the neck of the uterus. It is necessary to remember that cancer attacks any part of the cervical endometrium, therefore an early cancerous ulcer in the middle of the cervix will run a great chance of being missed by a surgeon who is content with a subtotal hysterectomy.
It is certain that cancer does occasionally attack a cervical stump left after subtotal hysterectomy at such an interval after the operation as to make it certain that the cancer did not exist at the time of the operation. Such a case occurred in my practice. I performed subtotal hysterectomy in 1901 on a woman forty-two years of age, mother of one child; eighteen months later there was a cancerous ulcer on the cervix; the whole of the cervical stump was promptly removed and the nature of the disease established microscopically. In 1908 the patient was in excellent health.
In another case under my care I performed total hysterectomy for fibroids in ignorance that the patient had cancer of the cervix. Some months after the operation cancer recurred in the vaginal vault and scar of the hysterectomy; the neck of the uterus had been preserved by the doctor, and on examination the cancer was found. In this instance, although total hysterectomy was performed, it had no effect in staying the course of the disease.
It is necessary to utter a caution in regard to the occurrence of cancer of the cervix after subtotal hysterectomy. I removed a uterus containing a large globular submucous fibroid from a barren married woman forty-five years of age. Six years later she came under my observation with a large granulating and bleeding growth on the cervix uteri. I had no doubt from the naked-eye characters that this was a primary carcinoma, although it surprised me to find it there, especially as the woman had never been pregnant. On my urgent representations she allowed me to remove the cervix. On microscopic examination the suspected cancer turned out to be a granuloma. Two years later the patient was in good health. Polk has recorded a similar experience. These facts show that caution is necessary in accepting reports of cancer of the uterine stump after subtotal hysterectomy.
=Cancer of the body of the uterus and fibroids.= In deciding between total and subtotal hysterectomy for fibroids the probable presence of cancer requires consideration in another aspect. Although uterine fibroids do not predispose to cancer of the neck of the uterus, many writers in recent years have expressed their suspicions that the presence of a submucous fibroid favours the development of cancer in the corporeal endometrium. Piquand, in 1905, drew attention to this matter and emphasized what other observers had pointed out, namely, that a submucous fibroid is often associated with changes in the mucous membrane of the uterus, which not only causes excessive bleeding, but sets up inflammatory conditions giving rise to leucorrhœa, salpingitis, pyosalpinx, and morbid changes in the endometrium, rendering it susceptible to cancer. His statistics support his conclusions, for they represent that in one thousand women with fibroids fifteen will probably have cancer of the body of the uterus. My own observations support this opinion. This complication is found most frequently between the fiftieth and the sixtieth year of life. If we narrow the ages of the patient and exhibit the liability in its most emphatic form it would run thus: that in patients submitted to hysterectomy for fibroids over the age of fifty years, about ten per cent of them will have cancer of the corporeal endometrium.
In 1906 I looked through the case-notes of five hundred patients who had been submitted to operation for uterine fibroids under my care. Of these sixty-three patients had attained the age of fifty years and upwards. Among these sixty-three women there were eight cases of cancer of the corporeal endometrium; the nature of the disease in each case was verified by careful microscopic examination.
Consequently, in performing subtotal hysterectomy for fibroids in women of fifty years and upwards, the surgeon should have the uterus opened immediately after its removal and assure himself that the endometrium is free from cancer. If there be any suspicion in this direction he should remove the cervix.
=Sarcoma.= The most insidious danger which besets the surgeon in dealing with fibroids of the uterus is the occurrence of an encapsuled sarcoma in the guise of an innocent fibroid. I have for some years dropped the name of myoma for these common uterine tumours, preferring to apply the term fibroid in a generic sense to all encapsuled tumours of the uterus. Every histological condition is found in them, from the hard calcified body looking like a block of coral to a soft diffluent collection of œdematous connective tissue, and tumours composed of tissue indistinguishable from spindle-celled sarcomata.
I have elsewhere recorded briefly a case in which I removed the uterus from a woman forty years of age, which contained a fibroid as big as an ostrich’s egg. On section it appeared to be a moderately firm fibroid, with its tissue whorled as is usual in hard fibroids and enclosed in a complete capsule. Some months later the patient complained of pain, and on examination a hard mass occupied the floor of the pelvis; a portion of this was excised and submitted to three competent histologists, who reported the growth to be an innocent fibroid. The patient died fourteen months after the primary operation with her pelvis filled with recurrent growth. The tumour was a spindle-celled sarcoma.
Much has been written regarding the sarcomatous degeneration of fibroids. In this matter I have maintained an attitude of active scepticism. My experience amounts to this: the case which I have briefly described is the only example in a thousand cases of hysterectomy in which an encapsuled sarcoma in the guise of an innocent fibroid has come under my observation, therefore I come to the conclusion that it is an uncommon event, and on turning to the literature of the subject it will be found that unequivocal examples are few.
From a careful study of the question, I have formed the opinion that if a woman with fibroids and concomitant cancer of the neck of the uterus seeks advice on account of hæmorrhage, and the cancer has attacked the vaginal portion of the cervix, the nature of the case will be appreciated. The cases likely to be overlooked are those where the cancer is situated somewhat higher in the cervical canal than usual, so that it is not easily detected by the examining finger, and so low in the cervix that the disease is not exposed when the body of the uterus is amputated in the course of a subtotal hysterectomy. A knowledge of this, as well as the fact that cancer of the cervix is almost exclusively a disease of women who had been pregnant, should make the surgeon particularly careful in performing subtotal hysterectomy for fibroids in women who have had children, in order to assure himself that it is not cancerous.
In addition to the liability of the stump left after subtotal hysterectomy to become cancerous, it is stated by some surgeons that the patient is more liable to intestinal obstruction than after the total operation. This objection is easily met, because a perusal of their writings shows clearly that they do not perform the operation properly. In subtotal hysterectomy, performed according to Baer’s instructions, there should be no stump projecting from the pelvic floor, but merely a thin seam underlying the base of the bladder.
I have dealt in detail with these two methods of hysterectomy, because when it can be performed subtotal hysterectomy is, as a rule, a simpler operation than total hysterectomy. There are conditions in which it is imperative to remove the whole of the cervix, especially when the canal is very patulous and perhaps septic; when it is large and hard, or large and spongy; and especially if there is the least suspicion of malignancy in the cervix, or in the body of the uterus.
It must, however, be borne in mind that cancer has attacked the scar left in the vagina after a total hysterectomy (Quénu). At the present time the subtotal method enjoys the greatest favour in London, but it must be remembered that where the total operation is most indicated, it is often difficult of execution. Although I have a decided preference for the subtotal operation, especially in spinsters and barren wives, I have performed total hysterectomy in more than 200 patients, so that I am in no way blind to its merits.
=Cancer of the uterus after bilateral ovariotomy.= The uterus, after complete removal of both ovaries, is not only a useless organ, but it may become attacked by cancer. Blacker reported a case in which a woman, thirty-nine years of age, underwent bilateral oöphorectomy for a uterine fibroid: eight years later cancer attacked the neck of the uterus and destroyed the patient.
In 1902 I performed abdominal myomectomy on a woman forty-seven years of age, and removed both ovaries and Fallopian tubes; the latter contained pus. Four years later this patient came under observation with extensive cancer of the cervix.
In 1901 a patient had bilateral ovariotomy performed; five years later she complained of severe uterine hæmorrhage. I removed the uterus by the abdominal route (total hysterectomy). The corporeal endometrium was cancerous throughout. The patient survived the operation six months. Similar cases have been recorded by Martin, Butler-Smythe, and Playfair.
=Adenomyoma of the Uterus.= This disease has not received adequate recognition at the hands of British surgeons, yet it is a condition which occasionally causes much doubt in the surgeon’s mind in the course of hysterectomy. This adenomyomatous change affects the endometrium and is, in some cases, associated with interstitial and subserous fibroids: it causes often great enlargement of the uterus, and under these conditions the fundus can be felt high in the hypogastrium. The patients are often profoundly anæmic as the result of long-continued menorrhagia. The physical and clinical signs of the disease are those present in patients with a large degenerating submucous fibroid. Indeed the surgeon often removes the uterus under this impression, and, after the operation is completed, when he divides the uterus expecting to see the usual encapsuled tumour, to his surprise finds a uterus with greatly thickened walls (Fig. 16).
Microscopically the adventitious material is made of irregular tracts of endometrium containing glands and strands of unstriped muscle tissue.
It is important for the surgeon to recognize these cases because, contrary to the rule with simple uterine fibroids, these adenomyomatous uteri are often adherent to the adjacent bowel and to the bladder: in connexion with this fact several observers have pointed out that uteri affected with this disease are often associated with inflammatory affections of the Fallopian tubes, and there are good reasons for the belief that the adenomyomatous change has a microbic origin. In this connexion it is worth mention that adenomyomatous uteri are sometimes tuberculous (Fig. 17). Some examples of this disease have been mistaken for cancer of ‘the body of the uterus’.
In this disease subtotal hysterectomy gives admirable results, immediate and remote.
THE FATE AND VALUE OF BELATED OVARIES
The only improvement of any importance made in Baer’s operation of subtotal hysterectomy concerns the ovaries. These Baer removed with the Fallopian tubes, but in 1897 I advocated, at the Obstetrical Society, London, that they were of great value to the patient, and pointed out that their conservation, when healthy, spared the patient the annoyance of that curious vaso-motor phenomenon, known to women as ‘flushings’, which is the only obtrusive sign of the menopause.
It is now admitted by those surgeons in London who have had much experience of hysterectomy for fibroids, that the immediate results of preserving at least one healthy ovary in this operation are admirable, especially in women under forty years of age, for the retention of an ovary is of striking value ‘in warding off the severity of an artificial menopause’ (Crewdson Thomas).
Although I have left one or both ovaries in the performance of abdominal hysterectomy for fibroids in more than 300 patients, in only two instances have I found anything detrimental in the practice. In these two patients it was necessary to remove one of the ovaries. Since 1906 I have modified the method by leaving only one ovary, even when both were healthy, and find that the immediate good consequences of the operation are in no way impaired. There is reason to believe that whatever good effects follow the practice of leaving a belated ovary (that is, an ovary divorced from the uterus and left in the pelvis), they are temporary, for in the course of a few years the ovarian tissue disappears and the patients experience the usual symptoms of the menopause. It is possible that the rate of atrophy of the secreting tissue of a belated ovary depends on the age at which a patient is submitted to hysterectomy.
In 1898 I performed subtotal hysterectomy on a woman, thirty-one years of age, for fibroids, conserving the right ovary. Nine years later (1907) I operated again for intestinal obstruction, and found this ovary healthy and functional, for a ripe corpus luteum was visible on its surface. Even a portion of an ovary, if it contain follicles, will maintain menstruation.
In performing abdominal hysterectomy for fibroids, there are three points which require consideration in relation to the subsequent comfort of the patient, and they depend mainly on the conservation of a healthy ovary. These three points relate to: (_a_) the patient’s comfort in securing freedom from flushings; (_b_) if she be married, her marital relations; and (_c_) if single, her nubility.
In regard to marital relations in women with a belated ovary, nothing trustworthy is forthcoming, but I believe the retention of an ovary is an additional factor in promoting domestic bliss. The question of nubility is interesting; I am able to state that women who have had subtotal hysterectomy performed, with conservation of one ovary, have married and lived happily with their husbands; and I am of opinion that the preservation of the vaginal segment of the neck of the uterus is an important factor, as it leaves the vagina intact, and though such women are sterile, they are certainly nubile.
Without overstating the case it may be said that a belated ovary is a very precious possession to a woman under forty years of age, whether she be married or single.
In regard to the fate of such ovaries, in the present condition of our knowledge it may be stated that:--
In a woman under the fortieth year of life, a belated ovary remains active and discharges ova.
An ovary belated after the fortieth year of life atrophies, and menopause symptoms will often ensue in the course of a few months after the operation. The retention of an ovary minimizes the menopause disturbances, and they are never so acute and prominent under these conditions as they are when an acute menopause is induced by the sudden and complete removal of all ovarian tissue. Some experienced observers maintain that an ovary is a valuable possession to any woman who menstruates, even at the age of fifty years, the persistence of menstruation being obtrusive evidence that this gland is functional. Experimental evidence, obtained from rabbits, proves that the removal of the whole uterus has no deterrent effect on ovulation, and it does not prevent the occurrence of œstrus and ovulation at periodically recurring intervals. There is no necessity to appeal to experiments on animals in this matter, as clinical observations on women are most eloquent in proclaiming the great value of a conserved ovary when the uterus is removed on account of troublesome and dangerous fibroids.
In reference to the value of ovarian tissue after hysterectomy for fibroids, attention should be drawn to a modification of this operation known as the Abel-Zweifel method, by which a small segment of the menstrual area of the uterus is left as well as one or both ovaries: this permits menstruation to continue in a subdued form.
Doran has particularly studied this method and practised it, but I cannot express any opinion as to its value, never having had the courage to perform it.
My aim in performing hysterectomy for fibroids is to abolish as completely as possible the menstrual area of the uterus (Fig. 18), and up to the present my efforts have been successful, and I have no complaint from any patient that this disagreeable phenomenon has manifested itself, although I have been at great pains by my own exertions, as well as by the kind efforts of those who have been associated with me in my hospital work, to keep in touch with women who have been so unlucky as to require such a serious operation as the removal of the uterus.
