Ileo-rectal fistula complicating advanced ovarian carcinoma.

Fistula between the bowels and an ovarian carcinoma is recognized but rare complication. Internal malignant fistula of the gastrointestinal tract involving two or more loops of different segments of the bowel and genitourinary structure are rare. The colon is frequently one of the participating loops. In reviewing the literature, however, we were unable to find a previous report of ileo-rectal fistula as a complication of an ovarian carcinoma. A case report and review of the English medical literature are presented with emphasis on the cause, clinical presentation, and management of advanced ovarian cancer with ileo-rectal involvement.
