Value of endoscopic retrograde pancreatography in pancreatic ascites

Endoscopic retrograde pancreatography was easily performed preoperatively in six patients with pancreatic ascites, and no complications resulted from this procedure. The abnormalities observed during the procedure were unpredictable and varied. Endoscopic pancreatograms provided delineation of the pancreatic ductal system, showing one or more sites of ductal leaks into pseudocysts or segmental narrowing of the main pancreatic duct. This preoperative information was invaluable in selecting appropriate surgical procedures.
