RESECTION OF TRANSVERSE COLON

By • Дек 18th, 2010 • Category: Colon

The transverse colon is in most cases resected for a cancer localized in its second and third quarters. With the tumour located in marginal regions of the transverse colon, i. e. in the neighbourhood of the hepatic or sple­nic flexure, a more extensive resection is indicated, i. e. right hemicolectomy or concurrent removal of the […]



VARIANT OF RESECTION OF TRANSVERSE COLON WITH ANASTOMOSIS OF ITS END TO THE SIDE OF SIGMOID COLON

By • Дек 18th, 2010 • Category: Colon

In those cases of transverse colonic resection when the entire left half of the bowel has to be removed, the end-to-end anastomosis in the region of splenic flexure may prove unreliable because of the tension and inade­quate blood supply of the intestine. Instead, an anasto­mosis between the end of transverse colon and the la­teral surface […]



RESECTION OF EXTERIORIZED TRANSVERSE COLON WITH FORMATION OF A LOOP COLOSTOMY

This operation is similar to that for cancer of the sig-moid colon in emaciated patients (see p. 274 and Fig. 173.2 and 3). It is indicated for patients in a state of severe cancerous intoxication, patients with disturbed regenera­tive processes, and in very obese individuals. All these cases involve so great a risk of anastomotic […]

The patient is placed on his back, the table being til­ted to the left in the course of […]
