A rare case of large jejunal diverticulum presenting as intestinal obstruction due to small bowel volvulus.

Jejunal diverticula are quite rare. Furthermore, small bowel diverticular disease resulting in volvulus can lead to complications necessitating surgical intervention. In this manuscript, we report a case of large sacculated jejunal diverticulum causing small bowel volvulus in a 40-year male. The jejunal mesentery at the base of the diverticulum was adhered to the terminal ileal mesentery forming a narrow base and complete small bowel going into volvulus by rotating around the narrow base. This case highlights a large jejunal diverticulum causing small bowel volvulus as an uncommon mechanism of complete small bowel volvulus. Although a rare entity, familiarity with jejunal diverticular disease, its complications and its management should be part of every surgeon's base of knowledge when considering abdominal pathology.
