A continuing appraisal of pancreatic ascites.

Pancreatic ascites is a distinct clinical entity characterized by elevated amylase and protein levels in the ascitic fluid. This should be distinguished from the ascites of cirrhosis, tuberculosis or metastatic carcinoma. Precise delineation of the ductal anatomy by endoscopic retrograde pancreatography preoperatively will enhance the ability of the surgeon to plan a rational operation and will, thereby, provide the best results. Medical treatment may obviate surgical intervention in a small number of instances but contains intrinsic hazards and should not be prolonged beyond three weeks. In carefully selected patients, limited pancreatic resection, encompassing the site of leakage, produces excellent results.
