Jejunal Diverticulosis

During routine exploration of the abdominal viscera before rectal carcinoma resection, diverticula were found in the jejunum of a 75-year-old woman. These outpouchings were located on the mesenteric side of the bowel. Because the patient was asymptomatic, no treatment was given. The rectal cancer was resected; her postoperative course was uneventful.Rarely, jejunal diverticula may be a significant source of GI bleeding. Perforation of these diverticula is highly uncommon. A massive diverticulosis of the small bowel may interfere with the absorptive function of the bowel and may cause malabsorption and steatorrhea.
