Total colectomy is indicated in multiple (familial) polyposis, total ulcerati­ve colitis, and multiple cancer of the colon.



RESECTION OF SIGMOID COLON (S1GMOIDECTOMY)

By • Дек 19th, 2010 • Category: Colon

In most cases sigmoidectomy is a single-stage opera­tion making possible full restoration of intestinal pa­tency by means of an end-to-end anastomosis. And it is only in cases of acute or chronic obstruction of the sig-moid that this has to be externalized and cut off toget­her with the tumour, with establishment of a loop sig-moidostomy. If […]



TECHNIQUE OF OPEN END-TO-END ANASTOMOSIS

By • Дек 19th, 2010 • Category: Colon

After exposing the posterior walls of the sigmoid stumps by means of Blllroth forceps (Fig. 171.5), the sur­geon unites them by No. 00 interrupted silk sutures (6— 8 sutures are applied). After tying the sutures, their ends are cut off except for the first and last which are left as stays.

Procedure for establishing closed anastomosis Because of the danger of infecting the peritoneum while opening the intestinal lumen, a number of Soviet and foreign surgeons employ the so-called closed techni­que of intestinal anastomosis. Two corrugating clamps are applied on either side of the sigmoid segment to be resected (preliminarily freed from mesosigmoid), with two ordinary […]



RESECTION OF EXTERIORIZED SIGMOID COLON WITH ESTABLISHMENT OF TEMPORARY LOOP SIGMOIDOSTOMY (Mikulicz-Grekov operation)

By • Дек 19th, 2010 • Category: Colon

This operation is employed in those cases when the surgeon fears to perform a primary resection with im­mediate anastomosis, i. e. in cases with partial obstruc­tion when there is discrepancy in the caliber of the two parts of segments of bowel to be united. The Mikulicz-Grekov operation is also indicated in emaciated patients, in very […]

By • Дек 19th, 2010 • Category: Colon

This operations is occasionally resorted to in order to provide a passage for faeces during the operative treatment of some benign lesions of the rec­tum and perineum, such as perineal deformity, inconti­nence or trauma of the sphincter, extensive rectovaginal fistula, etc.



RESECTION OF DESCENDING COLON AND SPLENIC FLEXURE

By • Дек 18th, 2010 • Category: Colon

Combined resection of the entire descending colon, splenic flexure, and distal transverse colon is performed in those cases when the growth is localized in one of these portions of the colon (see the Korte chart, Fig. 170). After such a resection intestinal continuty is restored by creating an anastomosis between the transverse and sigmoid colon. […]
