Rare Case of Sigmoid-Perianal Fistula due to Sigmoid Diverticular Disease: Report of a Case and Review of Literature

Abstract

Diverticular disease of colon is a common problem of western countries and its incidence usually increases with age. The natural history of diverticular disease is usually benign with only few patients developing episode of acute diverticulitis. Some patients may develop more complicated courses like hemorrhage, obstruction, stricture or fistulas. While colovesical and colovaginal fistulas are the common types of fistula, perianal fistula due to diverticular disease is an extremely rare complication of diverticular disease. We report a case of sigmoid-perianal fistula due to diverticular disease in a 53-year-old female patient without any signs or symptoms of sigmoid diverticulitis. Diagnosis was established in early course of disease by computed tomogram (CT) scan and a one-stage anterior resection was performed without any complication. We also performed literature review for similar cases and how they were managed.
