The Role of Endoscopy in Ampullary and Duodenal Adenomas

This is a clinical practice guideline for the use of endoscopic approaches in the evaluation and treatment of ampullary adenomas. The guideline discusses evaluation of ampullary lesions before endoscopic therapy, the role of endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) in assessment, and endoscopic resection. The role of EUS in management of duodenal adenomas is also examined. Adverse events and post-procedural care and surveillance are also addressed.
