A previously healthy 52-year-old woman was referred for difficult choledocholithiasis, documented during open cholecystectomy with bile duct exploration and T-tube placement. At our hospital, she underwent endoscopic retrograde cholangiopancreatography (ERCP) with plastic stent placement (10 Fr x 12cm) and T-tube removal. The patient arrived at the emergency room with acute abdomen, 12h after the ERCP. During the approach, there were signs of systemic inflammatory response, and an abdominal computed tomography scan showed that the proximal end of the biliary stent was in the bile duct and the distal end was perforating the third part of the duodenum (Fig. 1). Upper gastrointestinal endoscopy corroborated the site of perforation by the endostent (Fig. 2). The patient underwent laparotomy with endostent extraction, primary closure of the duodenal perforation (Fig. 3), bile duct exploration with choledocholithiasis resolution, and verification through intraoperative cholangioscopy (Fig. 4). Duodenal perforations due to endostents are not considered in the Stapfer classification.1 Such perforations are rare (1%) and due to stent migration (which occurs in 8–10% of the cases).2 The majority of reported cases have involved stents larger than 10 Fr x 12cm.2,3 Treatment is endoscopic in the absence of peritonitis, or surgical in patients with retroperitoneal collections, sepsis, or peritonitis.1,2
