Abstract

Gallstone ileus is a rare complication of secondary gallstone formation, most often due to a cholecysto-duodenal fistula with the passage of a stone into the small intestine. Obstruction occurs when the stone obstructs a narrowed segment of the digestive tract. Gallstone ileus is a surgical emergency, and its management is focused on relieving the obstruction. Treatment of the biliary-digestive fistula is considered based on the local and general condition. The best approach remains prevention through the diagnosis and treatment of acute cholecystitis.
