An evaluation of endoscopic pancreatocholangiography in surgical patients

Retrograde pancreatocholangiography was successful in 110 or 83 per cent of 133 patients suspected of having pancreatobiliary disease. Cannulation of the pancreatic duct was successful in 95 per cent of the patients suspected of having disorders of the pancreas. In 84 per cent, the biliary tree was successfully visualized among the group suspected of having disorders of the biliary tract. Dilatation of the main pancreatic duct in association with cholelithiasis and choledocholithiasis was observed in 33 and 72 percent, respectively.
