title: Measurement of the endoscopic retrograde cholangiogram.
abstract: The diameters of the common hepatic and bile ducts were measured in 100 endoscopic retrograde cholangiograms, and the effect of magnification was determined. Duct diameters were magnified by up to 48%. They were increased in some patients with chronic pancreatitis and after cholecystectomy, but were sometimes normal in patients with extrahepatic biliary obstruction.
