Gallstone ileus is a rare form of small bowel obstruction caused by an impaction of a gallstone within the lumen of the small intestine. Such a gallstone is hypothesized to enter the gut lumen via cholecysto-enteric fistula. Large stones, >2.5 cm in diameter, are thought to predispose to fistula formation by gradual erosion through the gallbladder fundus. Most commonly, obstruction occurs at the distal ileum (i.e. ileocecal valve), but can occur at almost any other location in the GI tract.

The name "gallstone ileus" is a misnomer because an ileus is, by definition, a non-mechanical small bowel motility failure.

Diagnosis

Diagnosis of gallstone ileus requires radiographic studies. Classic findings of pneumobilia, small bowel obstruction, and radiolucent gallstone on abdominal plain films is known as Rigler's Triad.

Treatment

Since gallstone ileus constitutes a form of mechanical small bowel obstruction, it can be a surgical emergency and requires laparoscopic removal or propulsion of impacted stone.

Eponym

This condition is also known by the eponym Bouveret's Syndrome.
