Colo-uterine Fistula Caused by Sigmoid Diverticulitis

A colo-uterine fistula is a rare complication of diverticular disease, due to the resistance of the uterine tissue. Only 18 cases have been reported in the world literature. Here, a case of an 82-year-old woman, with a colo-uterine fistula secondary to diverticulitis, is described. She presented with a malodorous vaginal discharge. A barium enema revealed colonic diverticulosis with a fistula tract to the body of uterus. The clinical symptoms were not specific, with the exception of the purulent material and stools from the vagina. A Sigmoidectomy, with fistula tract removal, and simple closure of the uterus was performed curatively.
