this report describes a patient with a cholecystocolic fistula whose presentation was unusual because it lacked the signs and symptoms that suggest biliary disease ( abdominal pain , food intolerance , and belching ) and because the fistula was not visualized on barium enema but was apparent on endoscopic retrograde cholangiopancreatography after incidental pneumobilia discovered on ultrasound directed our attention to the biliary tree .
