DIVISION OF SPHINCTER FOR THERAPEUTIC PURPOSES

By • Дек 26th, 2010 • Category: Anus

In some diseases of the rectum we have to resort to partial division of the anal sphincter in the course of operation, so that its function could be temporarily ar­rested or decreased. It is our practice to perform such sphincterotomy in operations for anorectal abscesses, anal fistulas and anal fissures by incising the sphincter from […]



OPERATIONS FOR ACUTE ANORECTAL ABSCESSES

By • Дек 26th, 2010 • Category: Anus

A patient with an acute anorectal abscess must be operated on within a few hours after the establishement of diagnosis. Anorectal abscesses are usually located in the perirectal or perianal fatty tissues and may be clas­sified, according to their site of origin, into the following four types (Fig. 57, 1, 2 and 3, and Fig. […]



The operation for acute anorectal abscess with sphincterotomy through the internal abscess opening (Rygick’s method)

By • Дек 26th, 2010 • Category: Anus

This method is used in ischiorcctal and pclvirectal abs­cesses. A scmilunal incision is made to lay the abscess cavity wide open. The surgeon then introduces his index finger into the abscess cavity, while inserting his other index finger into the rectum (Fig. 62.1), This enables him to readily ascertain which rectal wall the abscess cavity […]



The operation for deep pelvirectal abscess

By • Дек 26th, 2010 • Category: Anus

Operation is performed under general anesthesia as in the preceding operation. A linear incision of the skin and subcutaneous and is-chiorectal fat is made on the lesion side, the deep wound is drawn widely apart with retractors (Fig. 63.1). and fibers of the levator ani muscles visualized on the wound bottom are carefully dissected with […]



OPERATIONS FOR HORSESHOE (BILATERAL) ANORECTAL ABSCESS

By • Дек 26th, 2010 • Category: Anus

In this form of anorectal abscess, which is encounte­red in 10—11 per cent of cases, the pus passes over from the right (or left) ischiorectal fossa to the opposite side, by skirting the anal canal either posteriorly, or, less fre­quently, anteriorly (Fig. 65 and 66). A primary abscess is in most cases an ischiorectal one […]



OPERATIONS FOR ANAEROBIC ANORECTAL ABSCESSES

By • Дек 26th, 2010 • Category: Anus

Anaerobic anorectal abscesses are uncommon, and may develop from an acute anorectal abscess which has not been operated on it time. Three forms of anaerobic abscess are distinguished: (1) suppurative; (2) progres­sive gangrenous; and (3) abscess with anaerobic lym­phangitis. In suppurative anaerobic abscess no tissue crepitation is elicited on palpation and the pathologic process does […]



OPERATION FOR SUBCUTANEOUS FISTULA (after Gabriel)

By • Дек 26th, 2010 • Category: Anus

This operation essentially consists in laying open the fistula into the rectal lumen with removal of a flap of surrounding skin and mucosa. Under local anesthesia or general nitrous oxide anesthesia, a 1 per cent methylene blue solution is injected into the fistula followed by the passing of a fine grooved director, he surgeon then […]



ATTENTION! A FREQUENT OPERATION LAYING OPEN THE FISTULA INTO RECTAL LUMEN WITH SUTURE OF THE WOUND BOTTOM First main operation. Rygick’s modification

By • Дек 26th, 2010 • Category: Anus

In those cases of the Gabriel operation for laying open the fistula when the surgeon has any doubt as to the subsequent function of the anal sphincter, we have sutured, beginning with 1953, the bottom and walls of the wound with catgut, leaving the skin margins unsu-tured. Figure 75.1 shows the surgeon inserting the needle […]



OPERATIONS FOR HIGH-LEVEL FISTULA

By • Дек 26th, 2010 • Category: Anus

Fistulectomy with dissection of the sphincter through the internal fistulous opening (Rygick’s method). Second main operation. Under local anesthesia (see Fig. 30,1 and 2) or gene­ral anesthesia with azeotropic mixture, a 1 per cent methylene blue solution is injected into the fistulous tract and a vertical incision of perineal skin is made so that its […]



AUTHOR’S VARIANT OF OPERATIONS FOR VERY LONG FISTULOUS TRACTS

By • Дек 26th, 2010 • Category: Anus

When an anal fistula is very long and its external opening lies on the buttock or near the trochanter we, rather than making large incisions, make use of our own procedure as shown in Fig. 80,1, 2 and 3. In this opera­tion, the fistulous tract is cut across 3—4 cm from the anus, and its […]
