Distal jejunal gallstone ileus-an unusual cause of bowel obstruction: a case report.

Gallstone ileus is a rare entity that causes bowel obstruction by gaining access through a cysto-enteric fistula. This is a case report of a 70-year-old man presenting with small bowel obstruction secondary to distal jejunal gallstone ileus impaction. He is not known to have any predisposing factors. He was managed effectively with an enterolithotomy. Early diagnosis is key to a good prognosis. Although other management options are available, enterolithotomy with or without cholecystectomy remains the gold standard of management.
