BACKGROUND/AIMS: To examine the utility of placement of pancreatic duct spontaneous dislodgement stents for prevention of post-ERCP pancreatitis in patients with difficulty in selective biliary cannulation.
METHODOLOGY: The incidence of pancreatitis was compared between the group with P(+) pancreatic duct spontaneous dislodgement stent placed for prevention of post-ERCP pancreatitis and the group without P(-) in patients with difficulty in selective biliary cannulation.
RESULTS: The final success rate of selective biliary cannulation was 94.45%. Post-ERCP pancreatitis was observed at 7.07%. The success rate of placement of pancreatic duct stent in the P(+) group was 99.0%. The incidence of pancreatitis in 99 patients in the P(+) group was 3.0%, that of abdominal pain was 3.0%, that of hyperamylasemia was 16.2%, and the mean post-ERCP amylase level was 353.031 +/- 520.792 IU/L. The incidence of pancreatitis in the P(-) group was 11.1%, that of abdominal pain was 20.2%, that of hyperamylasemia was 33.3%, and the mean post-ERCP amylase level was 541.204 +/- 771.843 IU/L. Comparing between the P(+) group and P(-) group, the incidence of pancreatitis, that of abdominal pain, that of hyperamylasemia and the mean post-ERCP amylase level were significantly decreased in the P(+) group (p<0.05).
CONCLUSION: Placement of pancreatic duct spontaneous dislodgement stent in patients with difficulty in selective biliary cannulation could be useful for prevention of post-ERCP pancreatitis.
