Sigmoido-cervical fistula due to diverticular disease

Abstract

Introduction: Diverticular disease is complicated by fistulas in 4% to 23% of patients.

Case Report: A woman 52 years-old previously operated on with parcial histerectomy was successfully treated with antibiotics due to diverticulitis complicated with an abscess. Three months later the patient presented with vaginal discharge of faeces. Computed tomography showed wall thickening of sigmoid colon and vesical wall. Colonoscopy exclude cancer and confirmed the exit of gas through vagina. En-bloc resection of the sigmoid colon with traquelectomy with primary anastomosis was performed. The postoperative course was good without recurrence after 12 months of follow up. Sigmoido-cervical fistula is a very rare benign fistula due to diverticular disease. Diagnosis is basically clinic, but tomography and colonoscopy are important to exclude other causes of fistulas. Radical surgery with primary anastomosis is the standard treatment.
