Ileosalpingeal fistula: an unusual complication of Crohn's disease.

Enterosalpingeal fistula is a rare complication of Crohn's disease that is rarely diagnosed pre-operatively. We describe two cases of enterosalpingeal fistula. Both cases were diagnosed during exploration and required en bloc resection of the small bowel and fallopian tube. Literature review yielded only one specific case report of ileosalpingeal fistula and two other cases described in a larger series. Management of ileosalpingeal fistula should include resection of the diseased bowel as well as removal of the affected fallopian tube. Crohn's disease has an extremely wide spectrum of clinical manifestations. The hallmark of Crohn's disease is bowel inflammation with fistula or stricture formation. Organs commonly involved in fistula formation include the skin, small bowel, colon, and bladder. Rare fistula sites include the duodenum, stomach and gynecological structures such as the ovaries, fallopian tubes and vagina. We present two cases of Crohn's disease of the terminal ileum fistulizing to the fallopian tube. There is only one specific report of an ileosalpingeal fistula, although another author has described two additional cases in a large series of Crohn's fistulas.
