Abstract
Using the new examination of endoscopic transduodenal pancreatocholangigraphy to diagnose of the diseases of pancreas and Biliary duct, we have made a new approach to the problem by direct endoscopic study of outer and inner fiberscope to observe the pancreatic duct and biliary duct. We used this method to insert the inner fiberscope from the ostium of papilloplastic surgery (2cases) to the common bile duct, and one case from the ostium of choledochoduo-denal fistula to the common bile duct. The other case was succeeded to insert to the pancreatic duct from the ostium of papilla Vateri. Because the instrument is still in improving, the observation of biliary duct and pancreatic duct is not sufficient, but if we continue to improve this kind of instrument, we can sure it will be the useful clinical examination.
