[Amplifying right colectomy: place in the treatment of obstructive proximal left colon cancer].

The results obtained about nineteen (19) patients operated by left colon cancer with variable grade obstruction have been analysed. Seventeen (17) patients operated due to obstructive left colon cancer situated: five (5) in distal transverse colon, other five (5) at splenic flexure and seven (7) in proximal descending colon but three of them with right synchronic neoplasias. The remaining two (2) that showed a cancer located at splenic flexure and the other one in proximal descending colon were reoperated three weeks later than a transverse colostomy had been performed owing to an obstructive condition. One patient had to be reoperated because a generalised peritonitis from a fistula with partial disruption on end to end ileo-colic anastomosis. Exteriorization of both ends was carried out with favourable evolution and subsequent reanastomosis. An exteriorized patient by splenic flexure cancer also had to be drained ten days later for a retroperitoneal abscess through a percutaneous puncture and a lesion grade 1 in lower pole of spleen was resolved with electrofulguration. No patient has showed invalidating diarrhea and all themselves have been stabilised with two or three stools daily about two month after surgery. Amplifying right colectomy is a safe procedure with low surgical morbimortality and take privileged place in the treatment of the patients undergoing synchronical neoplasias and/or carcinomas associated with polyps, specially in all those cases when a variable grade of obstruction have occurred.
