Sa1340 COST-EFFECTIVENESS OF EUS-DIRECTED TRANSGASTRIC ERCP (EDGE) COMPARED TO DEVICE-ASSISTED ENTEROSCOPY ERCP AND TRANSGASTRIC ERCP IN PATIENTS WITH ROUX-EN-Y ANATOMY

Roux-en-Y gastric bypass (RYGB) surgery remains the most common weight loss surgery in the United States. RYGB anatomy makes it difficult to access patients' biliary system, a requirement for treating choledocholithiasis and other pancreaticobiliary diseases. Commonly used approaches for transpapillary biliary interventions are either device-assisted enteroscopy (DAE) endoscopic retrograde cholangiopancreatography (ERCP) or transgastric (TG) ERCP. DAE-ERCP is limited by forward-viewing optics and imperfect accessories resulting in relatively low technical success rates.
