Abstract
Eedoscopic pancreatocholangiography is extremely useful for the diagnosis of the diseases of the pancreas and bili-ary aduct, and it is one of the essential means for their examination. At present, however, diagnostics of pancre-atogram has not been well established, and necessity for endoscopic examination of this region is being emphasized. We have therefore attempted the examination of pancreatic duct and biliary duct by inserting a fiberscope instead of a cannula into the doudenal papilla. The instrument used was a retrograde panceratocholangioscope (RPCS ), with a front-view fiberscope of 2 mm in diameter and 200 cm in length, with a field angle of 25 and 35. The Pan-view Fiberscope (PFS-BL) was used for the outer fiber-scope. For the examination, PFS-BL is first inserted into the duodenum, with the visual field in front-view, and RPCS is inserted from the biopsy forceps inlet to about 3 cm outside the tip of PFS-BL. Then the visual field of PFS-BL is changed from front to lateral view, RPCS is bent gradually into the visual field of PFS-BL and inse-rted into the papilla. This retrograde pancreatocholangioscopy has been carr-ied out on 8 cases to date, and successful observations were made on the inside of main pancreatic duct in one case and of the biliary duct in two casis after papilloplasty.
