Intraductal Radiofrequency Ablation for Residual Adenoma after Endoscopic Papillectomy: An Additional Treatment Modality Expected to Be Safe and Effective

摘要

Ampullary adenoma is rare, but it is increasingly being recognized due to the widespread use of endoscopy and cross-sectional imaging. It is a premalignant neoplasm that is managed by resection. Traditionally, it is managed by surgical resection by either pancreaticoduodenectomy or transduodenal ampullectomy, both of which are associated with significant morbidity and mortality. For these reasons, endoscopic papillectomy (EP) has been explored as an alternative to surgical resection because it avoids surgical morbidity and is relatively safe (complication rate of 18.2%, mortality rate <0.5%);1 however, the blind spot of EP is the intraductal extension of the adenoma into either the bile duct or the pancreatic duct.
