Endoscopic retrograde pancreatic parenchymography was performed in 152 cases, and good pancreatic parenchymogram was obtained in 70 cases, for whom, diagnostic possibility was pursued on chronic pancreatitis and pancreatic carcinoma by this method. In cases of severe chronic pancreatitis a partial or whole defects in pancreatic parenchymal picturers were showed by this method. While irregular pancreatic contour and non-uniform parenchymal picture were observed in moderate chronic pancreatitis.The pancreatic surface seen on X-ray in cm2 was divided by the greatest diameter of the main pancreatic duct in mm for obtaining the ratio of S/D, as a result, significantly lower value was obtained in the group of chronic pancreatitis as compared with normal group.By this method, pancreatic carcinoma was demonstrated as the filling defect of pancreatic field, and this method was useful for the diagnosis of carcinomatous invasion to the duodenal side of the pancreas and carcinoma which occurred at the peripheral part of the pancreas without affecting the main pancreatic duct.No particular and coincidental symptom was observed in 152 cases treated with this method.
