| [ Summary ] | An aorto-duodenal fistula is a rare complication, but it frequently causes massive and fetal gastrointestinal bleeding. The most common case of a primary aorto-duodenal fistula is rupture of an abdominal aortic aneurythma. A secondary aorto-duodenal fistula can occur as a complication of vascular reconstructive surgery, typically as a consequence of dehiscence of a vascular suture line or, more often, as a result of infection. In many cases, what appears to be slight or moderate bleeding is a herald of massive hemorrhage to come. Duodenocolic fistula is also an uncommon condition characterized by diarrhea, feculent vomiting, and weight loss. Most malignant duodenocolic fistulas arise from colonic carcinoma of the hepatic flexure or transverse colon. In benign duodenocolic fistula however, many causal factors have been suggested, such as Crohn's disease, ulcerative colitis, peptic ulcer perforation, tuberculosis, colonic or duodenal diverticulitis, and gallstone ileus. |
