Abstract
After surgical resection, cancer of the papilla of Vater slows better prognosis than that of pancreatic head and extrahepatic bile duct. Recently, papillectomy has been accepted as an endoscopic treatment for an adenoma of the papilla of Vater. However, some problems to be solved still remain such as differential diagnosis of the papillary tumors, cancer staging, indication for endoscopic papillectomy and prevention of complications. In this paper, the author discussed these problems with special references to endoscopic procedures.
