Fifteen patients underwent jejunal resection for a serious complication of jejunal diverticulosis. Five of these were explored because of intestinal hemorrhage. Five patients developed acute jejunal diverticulitis, and three others required operation to relieve acute intestinal obstruction related to the jejunal diverticula. Two patients were explored for intractable abdominal pain, and in both instances resection of jejunal diverticula relieved the problem. In many of these patients the diagnosis of jejunal diverticulosis had been overlooked or ignored for years. The triad of obscure abdominal pain, anemia, and dilated loops of jejunum should alert the clinician and radiologist to a careful search for jejunal diverticulosis.
