Asymptomatic cholecysto-enteric fistula and gallstone ileus: Two case reports

Abstract

Cholecysto-enteric fistula (CEF) is an uncommon complication that can be seen incidentally during elective surgery or as a cause of mechanical intestinal obstruction. It usually involves elder females having comorbid conditions. Stones that pass into the small intestine due to CEF present themselves with recurrent ileus attacks and the clinical picture becomes apparent in case of complete obstruction. Very small stones, however, can be eliminated from the digestive system without causing ileus. There is no predictor for the development of CEF either in patients unaware of their gallstone or in those aware of their gallstone but asymptomatic. Thus, the diagnosis is established based on tests performed in emergency conditions or accidentally during elective surgery. Herein, we present two cases; the one with gallstone ileus due to CEF and the other with CEF detected during elective surgery
