Colouterine fistula relating to diverticulitis: a rare clinical entity

Colouterine fistula is a rare but recognizable complication of diverticulitis. This case illustrates the presence of a colouterine fistula in an elderly patient who had an atypical presentation for diverticulitis. She was initially treated with intravenous antibiotics for diverticulitis with a contained abscess. This gave her an opportunity to avoid surgery. However, her sepsis failed to respond to the initial treatment. Progress computerized tomography imaging demonstrated the presence of a colouterine fistula for which she required source control. Thus she underwent laparotomy, Hartmann's procedure, and total abdominal hysterectomy with bilateral salpingo-oophorectomy. The diagnosis of colouterine fistula was confirmed intraoperatively and on histopathology. Subsequently, the patient had an uneventful recovery following the operation. This case highlights the rarity but also the veracity of this clinical entity.
