ERCP performed through previously placed duodenal stents: a multicenter retrospective study of outcomes and adverse events

ERCP (endoscopic retrograde cholangiopancreatography) performed through previously placed enteral stents is an uncommon procedure without a significant amount of supporting literature, and with a wide reported range of technical success. The purpose of this study was to evaluate and better define the technical feasibility and safety of performing ERCP through enteral stents in patients with combined malignant biliary and gastric outlet obstruction (GOO).
