[Cholecystoduodenal fistule as a consequence of calculouse cholecystitis in a female elderly patient].

Bilioenteric fistules are fairly rare, cholecystoduodenal fistules are the commonest type, accounting for 70-80% of cases. Cholecystoduodenal fistules usually occur as a consequence of cholecystolithiasis and cholecystitis. Their symptomatology is atypical and fistules are frequently detected during surgery. Preoperative diagnostic procedures include visualization methods, such as US, CT, MRI, resp.ERCP. Both conventional laparotomy, as well as laparoscopy may be used in the treatment of the disease. Each of the methods has its pros and cons. The authors present a case review of a 85-year old female patient with a cholecystoduodenal fistule, diagnosed prior to the surgical procedure. Conventional laparotomy was elected as a method of treatment and the outcome was successful.
