Elements of Surgery

by Robert Liston

It has been said that lithotrity is applicable, when, from the advanced age of the patients and the rigidity of the parts to be cut, lithotomy is not. This statement is incorrect, at least the latter part of it. Old people, from 70 to 80, and even beyond that age, recover, when the operation is conducted quickly, without loss of blood, and so as to guard against infiltration, as certainly and rapidly as young persons. Within the last few years the apparatus for breaking up stones has been very much simplified and improved upon. The screw lithotrite can with great propriety and safety be employed in cases in which the concretion has not attained any very large size, and in which also the urinary apparatus is healthy, and tolerably free from irritability. The cases for this operation must be well chosen, and the proceedings conducted throughout with great caution, gentleness, and judgment. Very full directions are given in the “Practical Surgery” for the performance of this operation.

Perhaps no operative procedure has been more canvassed than that of lithotomy. The subject has been discussed, and the operation attempted, by many not very eminently qualified. All sorts of contrivances have been made and promulgated in connexion with this operation; the greater number intended to supply the want either of anatomical knowledge or of operative dexterity. A volume would scarcely contain a catalogue even of the instruments which are in my possession,—crooked staffs, knives, spoons, and forceps. I shall content myself with describing what appears to me the most simple, safe, and certain procedure.

The bladder may be opened, for the removal of stone, in various situations; at its forepart, by incisions above the pubes; in the posterior fundus, by division of the sphincter ani and a portion of the bowel; at its neck, by cutting upon it through the perineum. The first mode is termed the high operation, the second the recto-vesical, the last the lateral. The lateral shall be first considered: it is the safest, the most advisable, and the most frequently resorted to.

Keeping the patient in suspense for days after operation has been agreed on, with the view of preparing him as it is called, is prejudicial. Unless his digestive apparatus be in disorder, or he be labouring under some other affection incompatible with his safety should an operation be performed, the sooner he is cut the better. Delay often inflicts much mental suffering, is apt to induce despondency, and to weaken the defensive and reparative powers of the system. On the night before the operation, a dose of castor-oil, or other mild purgative, is to be administered, so as to obtain an empty state of the lower bowels; should this fail, an enema must be given.

The existence of a stone should be ascertained immediately before proceeding to the operation; it is not enough that the sounding was satisfactory the day before, or at any former period; and the operator will also, for his own sake, satisfy those who are met as his advisers and assistants of the fact that there is a stone in the bladder. All apparatus that may be required should be at hand. A grooved staff, a knife, forceps, a scoop, and an elastic-gum tube, are in general sufficient. A Read’s syringe should also be provided, lest the stone should prove brittle, and crumble under the forceps. When the operator has, by previous examination, ascertained that the stone is of an unusually large size, then he must be provided with a narrow, straight, and probe-pointed knife, with forceps of considerable length and grasp, and also with forceps so constructed as to effect crushing of the stone, should this prove necessary.

The staff should be curved, of a size sufficient to fill the urethra, or nearly so, and with the groove placed betwixt the convex surface and the side presented to the left of the patient. This form of instrument will prove the most convenient guide into the bladder. It is introduced fairly into the viscus, and made to touch the stone audibly. Its concave surface is raised towards the arch of the pubes, and retained thus, firmly hooked under the bones—as if with the intent of lifting the patient from the table—perpendicularly straight, without any inclination of the handle, or any bulging of the convexity towards the perineum. After being properly placed, the instrument is intrusted to an experienced assistant, who keeps it exactly in the same position from the beginning to the conclusion of the incisions. He at the same time elevates the scrotum, and standing behind the patient, leaves the surgeon with both his hands at liberty, and with the patient’s perineum all clear. The operator is thus enabled to guide the knife by the left hand; whereas, if he use a straight staff, his left hand must be solely devoted to the management of this instrument during the most delicate part of the incisions.

The staff is introduced either before or after the patient has been secured. The fixing of the patient is in this operation very necessary and important; on the proper management of that depends much the facility of completing the operation quickly and satisfactorily. Children are easily and conveniently held on the lap of an assistant, who, grasping the knees, places and secures the limbs so as to expose the perineum. In adults ligatures are indispensable; the hands and ankles are to be fixed together by means of strong and broad worsted tapes; and, in addition, the pelvis requires to be secured, and the limbs must be retained well separated, by two steady and powerful assistants, pressing obliquely down towards each other. A band may also with advantage be passed under the hams, and tied round the patient’s neck: the proper position is thus still further secured. The patient is placed on a firm table, of a height convenient to the operator, who is seated on a low stool. A table from two feet and a half to three feet in height, with a stool about a foot lower, will be found to suit very well. The instruments likely to be required are disposed in the folds of a towel placed on the floor, on the right side of the operator, and at a convenient distance.

Before proceeding to incise, the finger is introduced into the rectum to ascertain that it is in an empty state, and also to promote its contraction. A knife is used, with blade and handle somewhat longer than those of a common dissecting knife, and without any edge till within an inch and a half from the point,—held lightly in the fingers, the end of the handle resting on the palm. It is introduced close to the raphe, on the left side, and nearly opposite to where the erector penis and accelerator urinæ approach each other. Its point is made to penetrate through the skin, fat, and superficial fascia of the perineum, and is carried downwards with a slight sawing motion, by the side of the anus—about midway betwixt the anus and the point of the tuberosity of the ischium—and is continued till nearly past the lower part of the orifice of the bowel. The forefinger of the left hand is then introduced into the wound, and the resisting fibres of the transverse muscle of the perineum, and of the levator ani, are touched with the edge of the knife directed downwards. Wound of the rectum is avoided by pressing it downwards and to the opposite side by the finger; indeed the finger should be constantly in the wound as a guide to the knife. In this stage of the proceedings, incision upwards would be likely to interfere with the artery of the bulb, whatever its distribution may be,—whether the vessel come from the pudic, or from the posterior iliac. It occupies nearly the same relative situation in either case, and by care can always be avoided during the second incision. Division of it occasions most profuse, alarming, and dangerous hemorrhage. I have seen the patient lose much blood in consequence during the incisions; and after the occurrence of reaction, have seen the blood soaking through the mattrass, dropping from the foot of the bed, and collecting in pools on the floor. The bleeding is difficult to arrest; the application of ligature is very troublesome, if not impracticable, and efficient pressure cannot be made with safety.

In my own practice I have had little or no trouble from hemorrhage—chiefly, I believe, from never cutting upwards after the first incision. One instance of secondary bleeding occurred. The patient was sixty-one years of age, and had laboured under symptoms of stone for eight years. He had been dyspeptic for some weeks before the operation, but otherwise appeared a favourable subject. Very little blood was lost during the operation, but on the fifth day hemorrhage occurred to the extent of seven ounces; on the eighth day, the same amount was lost; on the twelfth, a pound; on the sixteenth, five ounces; on the seventeenth, about a pound. The bleeding was uniformly preceded by a feverish attack; and the blood had a florid, arterial appearance, and flowed rapidly. It proceeded from the interior of the wound, and a suppurating cavity in the neighbourhood of the prostate was felt by the finger. From the prostatic side of this abscess the blood appeared to spring; probably a considerable branch of the pudie ramifying in this situation had been opened by unhealthy ulceration. Pressure proved always effectual at the time, the hemorrhage recurring on the loosening and separation of the lint. After the last bleeding the dressing was retained for some days, and on its removal no recurrence took place. The patient had been much exhausted by this severe loss of blood, but, notwithstanding, made a good, and by no means tedious, recovery. In one case, also, troublesome hemorrhage occurred within twelve hours from the operation on a patient advanced in life. The bleeding was arrested with some difficulty by ligature and pressure. The patient died on the third day. The cause of the bleeding was found to be ossification, as it is called, or earthy degeneration of the coats of the vessels. The bleeding was from the external hemorrhoidals. The artery of the bulb was untouched.

Many patients have perished within the first day or two from bleeding, owing to the using of the knife too freely, and in an improper direction. By very slight application of the edge to the resisting fibres, and by gentle dilatation with the finger, the membranous portion of the urethra is reached. The knife is passed over the back of the forefinger in the wound, and lodged in the groove of the staff; it is then carried forwards through the prostate, with the edge directed downwards and outwards, cutting the gland obliquely. In this incision the knife is raised very little from the groove, the object being to divide the gland to the extent of no more than barely three-quarters of an inch. By so doing, the reflection of the pelvic fascia remains uninjured, and the boundary is left entire betwixt the external cellular tissue, and that loose and very fine texture immediately exterior to the bladder—betwixt it and the fascia lining the pelvis; thus the risk of urinary infiltration is done away with, at least much diminished. There is great danger in dividing the base of the prostate completely, and much more in cutting any part of the coats of the bladder. When the knife enters the groove of the staff, this latter instrument must be held very steady; if it be at all withdrawn, its point may escape through the wound, and mislead the knife.
