def: An abnormal connection between the gallbladder and the duodenum.
comment: Following an attack of acute cholecystitis, the resulting inflammation and adhesion of the gallbladder to GI, together with mechanical pressure applied by gallstones on the gallbladder itself and bowel wall, may result in an ischemic tear of the apposed gallbladder and enteric wall; this mechanism potentiates a fistula between the gallbladder and bowel where the gallstone could pass. Bouveret syndrome is the most infrequent variant of gallstone ileus. It results from a gallstone migrating through a bilioenteric fistula and causing obstruction at the gastric outlet and occasionally in also other portions of the intestine.
