Introduction:
Small bowel diverticular disease is uncommon, representing 1-2% of general population. The ileum diverticulum is very rare, especially if it is complicated by enterocutaneous fistula with abdominal wall abscess.
Presentation of the case:
Here, we report a case of small bowel diverticulum, ileum diverticulum with enterocutaneous fistula in a 65-year man presented with lower abdominal pain and an irreducible swelling for 5 days.
Dissection:
Diverticulosis has no exact cause, but theoretically the diverticula result from peristalsis abnormalities, intestinal dyskinesia, or high segmental intraluminal pressures. Complications of small intestinal diverticulum include bleeding, diverticulitis and its complication (e.g. fistula formation, and intra-abdominal abscess) [5].
Conclusion:
This is considered rare and serious complication of small bowel diverticulum could occur if diagnosis is delayed.
