Thirty four cases of pancreatolithiasis have been observed in a series of 3431 ERCP which was perfomed in our clinic during a period from December 1969 to September 1978. The clinical features and ERP findings were compared between alcoholic and non-alcoholic groups. Although age distribution in male demonstrated peak between 30-50 years of age, the stone were found in all age groups of female. Incidence in male was 7 times higher than that in female. The incidence of clinical symtoms, consisting of abdominal pain, low back pain and diarrhea, was slightly higher in alcoholic than in nonalcoholic group. Diabetes mellitus and hepatic dysfunction were more frequently assosiated with alcoholics than with non-alcoholics. As rare complications, two cases of idiopathic choledochus dilatation, which were not associated with alcoholabuse, and a case of annular pancreas showing alcoholic damage of pancreas, were observed. Pancreatic stone located mainly in the pancreatic ductal system and, in relatively localized cases, stones often presented in the distal portion of ductal stenosis. Although, the size of the stone in the alcoholic group was smaller than that of the non-alcoholics, there was no difference as to the relationship between ductal stenosis and stone size. Marked dysfunction of the exocrine pancreas was frequently detected in the cases having small and diffusely distributed pancreatic stone.
