A new technuque of ERC(P) using a straight-view fiberscope

A new technuque of ERC(P) using a forward-veiwing fiberscope is described in details. By this procedure the position of the maximal bended tip of the instrument provides a more selective cannulation of the common bile duct, preventing the risk of pancreatic duct filling. The method was performed in 15 cases and succeeded in 12. ERCP, using this technique, can be performed after normal esophago-gastro-duodenoscopy. However, at present time it is not a routine procedure. Technical improvements on the instrument are necessary to facilitate the method.
