Medications for Gallstone Ileus

Obstruction of the small intestine produced by passage of a gallstone from the biliary tract (usually the gallbladder as a result of cholecystitis) into the intestinal tract (usually by means of a fistulous connection between the gallbladder and the small intestine); occurrence and site of obstruction depend upon size of the stone, but the usual location is at or near the ileocaecal junction.
