Colouterine fistula complicating diverticulitis diagnosed at hysteroscopy: case report.

Since Noecker first reported a colouterine fistula secondary to diverticulitis in 1929, about 20 cases have been reported in the literature. Methods for diagnosis have yet to be established. Herein we report the first case of a colouterine fistula at the level of the isthmus diagnosed at hysteroscopy. Diagnostic hysteroscopy enabled rapid diagnosis of the colouterine fistula. Diagnostic hysteroscopy is the first-choice diagnostic tool for investigation of any abnormal vaginal discharge such as blood or stool because it enables direct vision and biopsy of the lesions of the lower genital tract quickly and at low cost.
