Upper gastrointestinal bleeding and Rigler triad.

Gallstone ileus is a rare complication of cholelithiasis, characterized by mechanical bowel obstruction due to a biliary calculus originating from a bilioenteric fistula.

We report the case of a 67-year-old male with a history of arterial hypertension and atrial fibrillation, who was admitted for acute renal failure (creatinine: 4.41 mg/dl) and hypotension. He also presented hyponatremia (129 mmol/L) and hypokalemia (2.
