Laparoscopically assisted enterolithotomy for a gallstone ileus in an atypical location.

Mechanical intestinal obstructions caused by gallstones occur in approximately 1% to 2% of cases. In most of the patients, the obstruction occurs at the ileocecal valve. However, gallstones may cause obstruction anywhere along the gastrointestinal tract from the stomach to the sigmoid colon. Laparoscopically assisted enterolithotomy can be used as a treatment method. This report describes a case in which a gallstone blockage caused a mechanical obstruction in an atypical location, which was successfully treated with a laparoscopically assisted approach.
