The surgical treatment of intestinal obstruction due to left sided carcinoma of the colon.

Forty two consecutive patients who underwent surgery for an obstructing carcinoma of the left colon over a 5 year period were studied retrospectively. Twelve patients underwent an initial defunctioning procedure with no hospital deaths but with four deaths after a mean follow-up of 25 months. Of the 30 patients who had a primary tumour resection, 7 died during the first hospital admission and a further 4 during a mean follow-up period of 23.7 months. The hospital mortality following primary resection was related to the site and timing of the anastomosis. During the first hospital admission 3 of 5 patients died after colocolic anastomosis, 3 of 10 died following ileocolic anastomosis, but only 1 of 15 died in those who did not have a primary anastomosis performed. The mean hospital stay of patients undergoing a delayed resection was 41 (s.e. (mean) 2.8) days compared to 24 (s.e. (mean) 2.8) days in those undergoing a primary resection. Primary tumour resection with a delayed anastomosis is recommended on the basis of these findings.
