Endoscopic retrograde cholangiopancreatography (ERCP) is commonly employed and highly accurate in the diagnosis of pancreatic neoplasms, chronic pancreatitis, and other pancreatic disorders. Standard catheters permit cannulation of both the bile and pancreatic ducts via the major papilla in 80% (67 to 100%) of cases in experienced hands1-s and visualization of the pancreatic ductal system in approximately 88% (68 to 95%).6-9 Failure to visualize the pancreatic ductal system might be a result oftechnical difficulties which arise due to a prior sphincterotomy (surgical or endoscopic), duodenal diverticulum, severe ampullar stenosis, obstructing neoplasm at the papilla or proximal pancreatic duct, or anatomical configuration of the pancreatic ductal orifice. In addition, in about 3 to 6% of cases, pancreas divisum is noted,1O-13 and only the small ventral pancreatic ductal system can be filled via the major papilla. A dorsal pancreatogram, which would be highly desirable, usually cannot be obtained. Cannulation of the minor papilla would obviously be of considerable benefit in these clinical situations. Unfortunately, some authors report a success rate of only 10 to 35% using standard catheters. lO, 11, 13 Dunham et al. 14 have reported a successful series of minor papilla cannulations, using a needle tip catheter or catheter with an hourglass shape in their series from Belgium. They reported success in 20 of 26 cases with pancreas divisum and in all of five cases with failure of pancreatography at the major papilla. We recently developed a blunt tipped needle catheter that allows easy cannulation of the minor papilla, giving a success rate of over 80%.
