Results

Success rates for bile duct cannulation by WGC without bow-up for the 15 degrees field of view and 5 degrees field of view were 87.5% and 57.5%, respectively (p<0.01). Success rates for bile duct cannulation by WGC with bow-up for the 15 degrees field of view and 5 degrees field of view groups were 90.9% and 80.5%, respectively. Total rates of bile duct cannulation for the 15 degrees and 5 degrees were 96.6% and 94.3%, respectively. As for accidents, incidences of acute pancreatitis for the 15 degrees and 5 degrees groups were 5.7% and 9.2%, respectively, with no significant difference seen.
