    Abstract:
    BACKGROUND/AIMS: Transpancreatic precut papillotomy (TPPP) is considered as an effective method in patients with difficulty in selective biliary cannulation. However, the use of placing a pancreatic duct stent as a measure against post-ERCP pancreatitis has not been clarified. Here we examine the methods of implementing TPPP safely. METHODOLOGY: TPPP was conducted on patients with difficulty in selective biliary cannulation. The incidence of pancreatitis was compared between group P(+) in which a spontaneous dislodgement type pancreatic duct stent was placed and group P(-) without a duct stent. RESULTS: The success rate of biliary cannulation was 83.3% at the first ERCP and finally 93.9%. Post-ERCP pancreatitis was observed in 9.09% of patients. The success rate of placement of pancreatic duct stent in the P(+) group was 100%. The incidence of pancreatitis in the P(+) group was 4.1% and the mean post-ERCP amylase level was 340.071 ±420.035IU/L. The incidence of pancreatitis in the P(-) group was 23.5% and the mean post-ERCP amylase level was 661.250±772.285IU/L. The incidence of pancreatitis and the mean post-ERCP amylase level were significantly lower in the P(+) group (p<0.05). CONCLUSIONS: In the patients with difficulty in selective biliary cannulation, TPPP is a useful technique for biliary cannulation. The placement of a spontaneous dislodgement type pancreatic duct stent after TPPP may be useful for prevention of post-ERCP pancreatitis.
