Abstract
Postoperative acalculous gangrenous cholecystitis is a serious and severe complication, especially in patients hospitalized in the Department of Reanimation. It occurs most often during vascular surgery or major digestive surgery, a polytrauma, in a context septic or in a context of shock. We report the case of a 74 year man who underwent surgery for femoral neck fracture. On the sixth postoperative day, he developed acute cholecystitis. Radiological examinations confirmed acalculous cholecystitis. After emergency cholecystectomy, anatomo-pathologic study confirmed the diagnosis of acalculous gangrenous cholecystitis.
