Operation in a typical case, after the method of Sir Spencer Wells and Dr. Thomas Keith.—The patient having had her bowels gently opened on the previous day, and being as far as possible in her usual state of health, should be warmly clad in flannel, both in body and limb, and laid on an operating table of convenient height, in or near the room she is to occupy. No carrying from ward to operating theatre and back again is admissible. It will be found both cleanly and convenient to have a large india-rubber cloth over the whole abdomen, cut out in the centre so as to expose so much of the tumour as is necessary, but gummed on or otherwise secured to the sides of the abdomen, and thus protecting the clothes, and hanging down over the edge of the table; this will prevent all wetting of the clothes and unnecessary exposure of the patient's person, and can be easily removed after the operation. Chloroform being administered, the bladder is evacuated by means of a catheter, and the patient's head and shoulders are elevated on pillows. An incision is then made in the linea alba, between the umbilicus and pubes, for about four inches in length at first, so as to be large enough to admit the hand, through all the tissues down to and through the peritoneum. Care is necessary in dividing the peritoneum, on the one hand, not to divide too much, in which case the cyst-wall will be penetrated, and the contents effused into the peritoneal cavity; or, on the other hand, too little, in which case the peritoneum may be mistaken for the cyst, and separated from the transversalis fascia under the idea that adhesions exist. Once the peritoneal cavity is opened, the incision through the peritoneum must be extended to the full length of the external wound by a probe-pointed bistoury.
The operator's hand must now be passed into the abdomen, and the tumour isolated from its connections as far as possible. When no adhesions exist it is extremely easy to pass the hand quite round the tumour, ascertain its relations to the uterus and Fallopian tubes, and the length and thickness of its pedicle. The presence of adhesions adds very seriously to the danger and duration of the operation. We will suppose at present that none exist in this typical case, and that the pedicle is found of a satisfactory size and shape. The surgeon now protrudes the anterior portion of the cyst-wall through the wound, and pierces it with a large trocar,[141] to which is attached an india-rubber tube, by means of which the effused fluid can be easily got rid of in any direction. During the escape of the fluid from the cyst a special assistant keeps up the tension by careful pressure on the abdomen. In cases where the cyst is multilocular, and thus only a portion of the contents of the tumour is at first evaluated, the operator should, by partially withdrawing the trocar, without removing it entirely from the cyst, endeavour to pierce and evacuate the other cysts, still through the original opening in the first one.
While doing this, great care must be taken lest he pierce the external wall of the tumour, and let any of the contents escape into the abdominal cavity; to guard against this, the punctures should be made by the right hand, while the left, re-inserted into the abdomen, supports the cyst-wall.
The tumour having been as far as possible emptied of its fluid contents, must now be dragged out of the wound, care being still taken lest any of its fluid contents escape into the peritoneal cavity. In favourable cases the pedicle is now brought easily into view. This may vary very much in length and thickness. It is sometimes entirely absent, the tumour being sessile on the broad ligament of the uterus; sometimes it is thick and strong, sometimes long and slender. The manner in which it is to be managed depends on its length and thickness. Varieties in treatment will be noticed immediately. We will suppose that it is four inches in length and one or two fingers in breadth. This is quite a suitable case for the use of the clamp, the principle involved in the use of which is, that the pedicle should be brought quite out of the abdomen through the wound and secured on the surface. The best form seems to be one made like a carpenter's callipers, with long but removable handles, and a very powerful fixing-screw.
The blades of this clamp being protected by pads of lint should be made to embrace the pedicle close to the cyst, in a direction at right angles to the abdominal wound, and lying across it, the handles should then be removed, and pads of lint placed below the clamp to protect the skin. The cyst may now be cut away at some little distance above the clamp, enough being left to prevent all danger of its slipping. Further to avoid this danger, the pedicle may be transfixed by one or two needles above the clamp.
The wound is now to be sewed up by several points of interrupted suture, some inserted very deeply through all the tissues, including even the peritoneum, others in the intervals of the first, including little more than the skin. They may be either of iron, silver, platinum, telegraph-wire (Mr. Clover's copper, coated with gutta-percha), or silk. It seems of very little consequence which is used. Sir Spencer Wells, after many trials, uses silk, as being removed with least pain to the patient, and really causing no more suppuration than the metallic ones do, if only removed early enough, viz., about the second or third day, by which time the union of the wound should be firm.
The after-treatment should be very simple. Except under special circumstances, stimulants are rarely necessary, and indeed, to avoid vomiting, as little as possible should be given by the mouth during the first twenty-four hours. The patient should be allowed to suck a little ice to allay thirst, and opiate and nutritive enemata will be found quite sufficient to keep up the strength in ordinary cases. The urine should be drawn off by the catheter every six hours. The room should be kept quiet, and the temperature equable, so long as there is no interference with a plentiful supply of fresh air.
Some of the specialities and abnormalities involving special risks may now be briefly noticed:—
1. Adhesions.—These vary much in amount, in position, in organisation, and danger.
a. In amount.—In certain cases no adhesions exist, while in others, omentum, intestines, tumour, uterus, and abdominal wall may be all matted together in one common mass.
