Seven cases with shortening of the main pancreatic duct in ERCP were studied. Almost all of them complained of upper abdominal discomfort or pain, poor appetite and four of them had remarkable emaciation. Their signs and symptoms mimic chronic pancreatitis or carcinoma of the pancreas. Laboratory data and drip infusion cholangio-graphy showed on abnormalities in all. Pancreatic scanning showed subnormal in a half of them but celiac angiography revealed no abnormality in all casess studied. The functional impairment of the exocrine pancreas was observed in only a case but hyperamylasuria or abnormal response of the blood amylase after pancreozymin and secretin administration were odserved in all of them. Postmortem pancreatogram of a case (Case 1) coincided with ERCP in all cases that the main pancreatic duct was short and distributed only to the pancreatic head. By the instillation of methylene blue into the papilla major and cogo red into the papilla minor, the pancreas was divided into two regions. The blue and red stained pancreas coinsided respectively with the distribution of the main pancreatic duct and the accessory duct. No communication of both ducts was detected but the pancreas was almost normal macro-and micro-scopically. As the cases with the short main pancreatic duct in ERCP complain of many GI troubles without special changes in the pancreas, we would like to propose a new clinical entity such as "Short main pancreatic duct syndrome" or "Malf nsion syndrome of the pancreas" for these cases.
