Colouterine fistula complicating diverticulitis: a case report and review of the literature

Abstract

Colouterine fistula, secondary to diverticulitis, is an extremely rare complication, and only few cases have been reported in the literature. We report the case of 76-year-old woman, who presented with vaginal discharge over a three-month period. Pelvic examination and laboratory investigations suggested a colouterine fistula, that was confirmed by non-invasive imaging. Surgical treatment was a one-stage, en bloc resection of the uterus and sigmoid colon. In the presence of severe inflammatory reaction or paracolic abscess, a two-stage procedure should be safer. Otherwise, a one-stage procedure, en bloc resection of the uterus and sigmoid colon is preferred, as we cannot rule out a malignancy prior to surgery.
