Peroral cannulation of the ampulla of Vater with retrograde cholangiography and pancreatography (ERCP) was successfully accomplished in 65 of 85 patients. Cholangiography was normal in six patients thought to have obstructive jaundice and demonstrated choledocholithiasis in eight, cancer of the common bile duct in three, cancer of the head of the pancreas in eight, narrowing of the common bile duct in three, and ampullary cancer in two. Pancreatography was normal in 12 patients, ruling out surgical lesions; pseudocysts were demonstrated in three, pancreatitis in 12, and carcinoma of the body and tail of the pancreas in two. No serious complications resulted.
Retrograde cholangiography and pancreatography provided a safe, quick, and accurate diagnostic technique that reduced the duration of preoperative investigation of the jaundiced patient and influenced the choice of operation in patients with pancreatic disease.
