title: Endoscopic approach to the patient with benign or malignant ampullary lesions.
abstract: Adenoma and adenocarcinoma are the most common ampullary lesions. Advances in diagnostic modalities including endoscopic ultrasonography and intraductal ultrasonography have provided useful information that aids in diagnosing and managing ampullary lesions. Endoscopic papillectomy can be a curative therapy for localized ampullary adenoma and have a role in the diagnosis of indeterminate ampullary lesions that may contain a hidden malignancy. However, the consensus on how and when to use endoscopic papillectomy has not been fully established. This article reviews the approach to the patient with benign or malignant ampullary lesion.
