Abstract
Background: Ampullary cancer is a malignant lesion in the pancreatobiliary system with a relatively good prognosis because of its slow growth, early appearance of symptoms and high resectability. Hndoscopic retrograde cholangiopancreaticography(ERCP) is an important and useful method in the diagnosis of ampullary cancer because it identifies the location of lesions endoseopically and by opacification of the bilio-pancreatic ducts and allows confirmation by biopsy, But the diagnostic accuracy of endoscopic forcep biopsy was variable according to the macroscopic appearance of ampullary cancer. In unexposed type ampullary cancer, biopsy after endoscopic sphincterotomy or intraluminal cannulatian biopsy has been recommended because the cancer tissue was either not visible at all or barely visible from the lumen of the duodenum. The purpose of this study was to evaluate the contribution of endoscopic sphincterotomy to the diagnosis of ampullary cancer and to compare the clinical eharasteristics of unexposed type ampullary cancer with those of exposed type ampullary cancer. Method: Thirty-one cases of the ampullary cancers over the past 5 years were reviewed. Macroscopically, thirty one ampullary cancers were classified into two types. The unexposed type ampullary cancer was defined normal ampullary mucosa with or without protruding. The exposed type ampullary cancer was defined abnormal ampullary mucosa including nodular, ulcerative, nodulo-ulcerative and polypoid appearance. Ampullary cancers were diagnosed preoperatively by forcep biopsy, biopsy after endoscopic sphincterotomy, or brushing cytology. (Korean J Gastrointest Endosc 17: 362-368, 1997) (continue)
