Meckel's diverticulum: an exceptional cause of vesicoenteric fistula: case report and literature review.

Unlabelled: Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract. It can cause complications in the form of ulceration, hemorrhage, intussusception, intestinal obstruction, perforation and, very rarely, vesicodiverticular fistulae as noted in six previously reported cases. 66-year-old woman was presented with an enterovesical fistula. Exploratory laparotomy revealed a vesico-diverticular fistula resulting from a perforated Meckel's diverticulum. Pathologic examination revealed that the diverticulum did not contain ectopic gastric or pancreatic tissue. The patient underwent a diverticulectomy and had an uneventful postoperative course. Unlike four of the six previously reported cases, our patient had no coexisting bowel or bladder disease occurring with her vesico-diverticular fistula.

Conclusion: This is only the third reported case of a vesico-diverticular fistula resulting from a perforated Meckel's diverticulum that did not contain ectopic tissue.
