The use of an omental graft to prevent leakage from the site of an intestinal anastomosis was first advocated by Nicholas Senn.1 He found that such grafts became firmly adherent to the intestine within 12 to 18 hours and were freely supplied with blood vessels within 18 to 48 hours. Since then others have reported the use of free or pedicled omental grafts in intestinal anastomoses,* perforations of the gastrointestinal tract,† and esophageal anastomoses,‡ and as a means of covering denuded peritoneal surfaces.§ Our interest in the use of free grafts of omentum stemmed from these reported studies. In particular, we wished to learn whether free grafts of omentum survived when they were placed about anastomoses of rectum and colon. If such grafts survived, it was thought they might help the surgeon to make a more secure anastomosis after the performance of a "low anterior resection" of the rectosigmoid,
