ID: 3524149 A MULTICENTRER STUDY COMPARING OUTCOMES BETWEEN 15MM AND 20MM LUMEN APPOSING METAL STENTS IN ENDOSCOPIC ULTRASOUND-DIRECTED TRANSGASTRIC ERCP (EDGE)

EUS-directed transgastric endoscopic retrograde cholangiopancreatography (EDGE) is an established technique for performing ERCP in patients with Roux-en-Y gastric bypass. The 15mm lumen apposing metal stent (LAMS) has been utilized in the majority of published studies to date. The newly available 20mm LAMS theoretically renders the procedure easier by providing a wider lumen to enable same-session ERCP (or “single stage EDGE, SS-EDGE”). However,...
