[Role of emergency subtotal colectomy in neoplastic obstructions of the left colon]

From 1984 to 1990, 60 patients underwent emergent surgery for a neoplastic obstruction of the left colon. We performed 19 colostomies without initial exeresis and 41 immediate tumoral resections. In the latter group, five subtotal colectomies (S.T.C.) were performed, including four with immediate mechanical anastomosis. Two patients had synchronous cancers and three had pre-perforating cecal lesions. Three patients had an associated general peritonitis. Three of the patients treated with STC died. These were these patients with general peritonitis, two of whom also had hepatic metastases. The data found in the literature on neoplastic obstructions of the left colon treated with STC with immediate anastomosis (227 cases are published) show an overall mortality rate of 8.4% with 24% morbidity, a complication of the anastomosis occurring in 4.5% of all cases.
