Pancreatic ascites. Intraoperative localization of the pancreatic fistula.

Pancreatic ascites can be diagnosed by demonstration of high amylase concentration in the ascites and ERCP may serve to identify the causal internal fistula. Intraoperatively a precise localization of the ductal leakage is helpful. In two patients we demonstrated the fistulas by stimulation of the pancreatic secretion with secretin.
