title: Pancreatic duct obstruction by a benign polypoid adenoma of the ampulla of Vater.
abstract: An unusual presentation of polyp of the ampulla of Vater is described. The patient initially had a chronic relapsing pancreatitis. Pancreatocholangiography revealed a tumor in the main pancreatic duct that proved to be a pedunculated polyp of the ampulla of Vater by operation. Transduodenal excision and sphincteroplasty may cure the lesion and relieve the symptoms of this disease.
