Abstract
Gallstone ileus is a rare but potentially serious complication of gallstone disease, which presents as a mechanical intestinal obstruction due to impaction and fistulization of a gallstone, most commonly in the small intestine. Since it usually occurs in elderly patients, the symptoms can be very diverse and with a late presentation. We present the case of a 90-year-old patient with intestinal obstruction and acute abdominal pain who experienced gallstone ileus and underwent surgery, and a few days after being discharged returned with a recurrence of the symptoms, was re-operated, and a second stone was found.
