Forty-six patients after pancreatoduodenectomy or total pancreatectomy were measured for serial changes in postoperative plasma levels of ALP, γ-GTP, and LAP, in which preoperative existing of choledochal dilatation was assessed to be contributory to the changes or not. ALP, γGTP and LAP returned to the normal levels 3 months after the operation in patients in whom choledochal dilatation was noted preoperatively. In patients without preoperative choledochal dilatation, γ-GTP and LAP also returned to the normal levels 3 months after the operation, while ALP remained elevated. In this group of patients, biliary stasis was suspected. These results suggest that small stoma of the choledochojejunostomy may play a causative role in biliary stasis.
