The chief risk is stricture of the orifice of the urethra. To prevent this, several modifications of the operation have been introduced.

1. Ricord's method.[163]—After the amputation the surgeon seizes with forceps the mucous membrane of the urethra, and with a pair of scissors makes four slits in it, so as to form four equal flaps, and with a silk ligature stitches each of these to the skin. Contraction of the cicatrix will thus tend to open rather than close the urethral orifice.

2. Teale's method.[164]—He slits up, by a bistoury on a director, the urethra and skin over it for about two-thirds of an inch, and then stitches the one to the other, thus making it a long oval dependent orifice (Fig. xxxviii.).

3. Miller's proposed method.[165]—"A narrow-bladed knife is first used to transfix the penis between the spongy and cavernous bodies close to the root; the knife having been carried forwards for an inch and a half, its edge is turned perpendicularly downwards, and the urethra and skin flap are divided, the cavernous bodies and dorsal integument being then cut perpendicularly upwards where the knife was originally entered for transfixion. A button-hole is afterwards made in the lower flap, though which the corpus spongiosum and urethra protrude, while the flap itself is turned upwards, and attached dorsally and laterally, so as to cover in the exposed cavernous structure."

Hydrocele.—The very simple operation necessary for hydrocele is thus performed:—The surgeon supports the tumour in his left hand so as to project it forwards, and make the scrotum as tense as possible in front. Having carefully ascertained the exact position of the testicle, which can generally be easily enough done by a finger accustomed to discriminate the difference between a soft solid, and a bag tensely filled with fluid, aided by the peculiar sensation of the testicle when squeezed, the surgeon enters a trocar and canula about an eighth of an inch in diameter into the distended cavity of the tunica vaginalis, near the fundus of the swelling. When it is evident the instrument is fairly entered, and not till then, the trocar is withdrawn, and the fluid allowed completely to drain off. When it ceases to flow the surgeon places his forefinger over the end of the canula to prevent the entrance of air, till he fits into its orifice a suitable syringe containing two drachms of the tincture of iodine, made according to the Edinburgh Pharmacopœia: the tincture of the British Pharmacopœia is not sufficiently strong. Having injected this cautiously into the cavity, the canula is withdrawn, and the surgeon, seizing the now flaccid scrotum in his right hand, gives it a thorough shake, so as to spread the iodine over as much as possible of the inner wall. When properly performed this very simple procedure very rarely fails to produce a radical cure; though less thorough operations, such as mere evacuation of the fluid, less stimulating injections, unguents introduced on probes, and the like, often fail of success, and thus give encouragement to absurdities, such as wire-setons, or to more severe operations, such as laying open the sac.

Hæmatocele.—When the contents of the sac of the tunica vaginalis are found to be grumous instead of simply serous, or when, as often happens, only pure blood escapes when the fluid is nearly evacuated, it is found that simple evacuation and injection are very rarely sufficient to effect a cure.

After they have been fairly tried, the sac of the hæmatocele should be laid open in its full extent; any large vessels which bleed should be tied, and the cavity then stuffed with lint. When the lint can be removed, which will be after two or three days, the edges of the wound should be brought closely together, and the cavity will then rapidly heal up from the bottom, and be obliterated by secondary union of granulations.

In cases where the walls of the cavity are enormously thickened, or even, as sometimes happens, almost bony in consistence, an elliptical portion may be removed with advantage.

Excision of Testicle.—This operation is rarely required except for tumours of the testicle. Hence the size of the incision necessary must vary much with the size of the tumour; and the amount of skin to be removed (if any) on the amount of adhesions it has formed to the tumour.

One or two points must be attended to in every case of extirpation of a testicle:—

1. The incision should commence over the cord just outside of the external ring, and be continued fairly over the tumour to its base.

2. As to removal of skin, some surgeons advise that none should be taken away, others that a considerable quantity can be spared. There is certainly less risk of secondary hæmorrhage if a portion be removed, than when a flaccid empty bag is left. The author invariably removes a very large quantity of skin if the tumour is large, as there is much more rapid healing, and the resulting scrotum is much more comfortable for the patient.

3. The cord should be exposed at the beginning of the operation, raised from its bed and given to an assistant, who should compress it gently, not from any fear of its escape into the abdomen, but to prevent hæmorrhage. If the tumour has been very large and heavy, the cord will have been much stretched, and if divided too high up, may really give trouble by its elasticity, unless the above precaution is taken. The cord then having been divided close to the tumour, the latter is removed, care being taken not to include the sound testicle in the removal. All the vessels are then to be tied or twisted, and the spermatic artery is to be secured alone, not, as used to be the case, included in a common ligature with the other constituents of the cord. Secondary hæmorrhage is very apt to occur from small scrotal branches which may have escaped notice during the operation.

Operations on the Anus and its Neighbourhood.—Fistula in Ano.—While much might be written on the pathology of fistula, and a good deal even on its diagnosis, a very few words will suffice to describe the simple and effectual operation for its relief.

Dismissing at once all so-called palliatives, drugs, unguents, pressure, and injections, as mere waste of time, and holding that the only method of cure consists in laying the fistula fairly open, the question narrows itself into this: What is the best method of laying it open? Prior to the discovery by Ribes of the great principle that the internal orifice of the sinus is always within an inch or an inch and a half of the orifice of the anus, the operations for fistula were most unnecessarily severe; the gut used to be divided as far up as the sinuses extended; and large portions of the anus used to be excised bodily along with the sinuses. It is now a much simpler and more satisfactory operation.

Operation.—A common silver probe bent to the required shape is passed into the external opening, or, if there are more than one, into the largest and oldest one. The forefinger of the left hand being introduced into the rectum, the probe is passed through the internal orifice, and its point brought out by the anus. The portion of tissue raised by the probe can then be easily divided with the certainty that the fistula is laid fully open. Anal fistulæ have been divided by the elastic ligature, but it seems slower in action and more painful, with no counterbalancing advantages.
