Retrograde pancreatocholangiography was first reported in 1968 by McCune based mainly on surgical cases; which in Japan, Takagi, Oi et al. developed and brought into practice a peroral method (endoscopic retrograde cholangiopancreatography or ERCP), which currently constitutes one of the most effective diagnostic procedures for the lesions in the pancreas and biliary duct. In this paper we would like to report on the clinical evaluation of ERCP carried out on 208 cases.Objects ERCP was carried out from July of 1972 to September of 1975 on 208 cases admitted in the 1st Department of Internal Medicine, Gunma University and affiliated hospitals suffering from and suspected of hepatic, biliary duct and pancreaic diseases. The ages ranged from 15 to 82 years.Results1. Successful cannulation into the papilla of Vater accounted for 182 of 208 cases or 87.5 %. The rate of successf of radiography indicated 92.5 % with selective bile duct radiography and 86.3% with selective pancreatic duct radiography.2. This method makes one of the effective examinations in differential diagnosis of obstructive jaundice.3. Significant correlation was recognized between the maximum diameter of the pancreatic duct and the patient's age.4. Significant corelation was recognized between the maximum diameter of the pancreatic duct and that of common bile duct.5. As characteristic radiographic appearances of the pancreatic duct with chronic pancreatitis, dilatation suggestive of a string of beads, snaking, cyst formation, etc. were demonstrated. For the definitive diagnosis of chronic pancreatitis through ERCP, however, further studies are required.6. By cytology of pancreatic juice following ERCP, discovery of early-stage pancreatic cancer can be expected.
