Parastomal hernia in relation to site of the abdominal stoma

Abstract

Parastomal hernia is a common late complication of enterostomy, especially colostomy, and sometimes requires surgical treatment. A possible contributory factor, location of the stoma in relation to the rectus abdominis muscle, was studied by examination of 130 patients with permanent intestinal stoma. The bowel had been brought out through the rectus abdominis muscle in 107 patients and lateral to it in 23 patients. The respective prevalence of parastomal hernia in these groups was 2.8 per cent and 21.6 per cent. The highly significant difference indicates that enterostomy should be constructed through the rectus abdominis muscle, not lateral to it.
