This case of aortoduodenal fistula, diagnosed by upper endoscopy, is rare but potentially fatal and difficult to diagnose

A man in his 60s, under follow-up by our cardiovascular surgery department, underwent abdominal aortic aneurysm graft replacement in April, year X. In December, he presented with abdominal pain and hematochezia. Labs showed anemia. Contrast CT was inconclusive, but ascending colon diverticula suggested possible diverticular bleeding. He was admitted for colonoscopy the next day.

Abstract

A man in his 60s, under follow-up by our cardiovascular surgery department, underwent abdominal aortic aneurysm graft replacement in April, year X. In December, he presented with abdominal pain and hematochezia. Labs showed anemia. Contrast CT was inconclusive, but ascending colon diverticula suggested possible diverticular bleeding. He was admitted for colonoscopy the next day.
