Abstract

Previous reports show evidence that perforation of the sigmoid colon with diffuse peritonitis, when conventionally treated (i.e. by suture, drainage, and proximal defunctioning colostomy) is associated with a high mortality. Recent investigations, however, indicate that the mortality can be lowered considerably if acute resection or exteriorization of the affected segment of the bowel is performed. Fifteen patients with perforated lesions in the sigmoid colon associated with diffuse peritonitis were treated with drainage and right transverse colostomy during the 10-year period 1963-72 with five deaths. In comparison, during the last years, ten patients with perforation and diffuse peritonitis were treated with acute resection or exteriorization of the affected segment of the bowel without any mortality. Though the two patient series are not completely comparable, the results imply that removal or exteriorization of the affected bowel is to be preferred in the surgical treatment of most perforated lesions in the sigmoid colon, even if the perforation is associated with diffuse peritonitis.
