@entity5 of the large bowel become often clinically evident as an obstruction in 8-29% cases, specially the @entity5 at the @entity4558 (50%) or descending colon (25%). Different factors (urgency, age, @entity694 and lack of adequate bowel preparation) influence therapeutic choice, specially about the bowel resection and one stage @entity254 . Twenty-six @entity1 with @entity5 of the large bowel (8 of ascending colon and proximal transverse, 5 of @entity4558 or descending colon, 12 of the sigma, 1 of the rectum) have been surgically treated. 4 @entity1 have been subjected to right emicolectomy and ileo-transverse @entity254 ; 2 to Hartman's operation; 1 to anterior resection of the rectum; 3 to left hemicolectomy and 2 to resection of the sigma with colic on table irrigation and one-stage @entity254 ; 13 to colostomy; 1 to palliative ileo-colic bypass. Two @entity1 (7.5%) died in post-operative period. In @entity1 subjected to one-stage procedures for left colic stenosis, the Authors haven't observed major complications, but one @entity1 developed an anastomic leakage (4%), conservative treated. In stenosis localized to ascending colon or hepatic flexure standard surgical operation is right emicolectomy. In @entity1 affected by @entity5 of descending colon, the Hartmann's operation is considered the more rational procedure, even if 50% of the @entity1 aren't reoperated on for reconstruction. The one-stage @entity254 is indicated only in selected cases, specially subjected to TPN before surgery or balancing of the metabolic parameters and to antibiotic prophylaxis. The subtotal or total colectomy is indicated when signs of colic perforation are found or when the colon is massively dilatated or there are signs of @entity39 or in case of other lesions of the large bowel preoperatively known.
