OBJECTIVES: This study aimed to evaluate whether synthetic secretin is effective in reducing post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis.
METHODS: This is a single academic medical center, prospective, randomized, double-blind, placebo-controlled trial using secretin (dose of 16μg) administered intravenously immediately before ERCP. Patients were evaluated for the primary outcome of post-ERCP pancreatitis as diagnosed by a single investigator.
RESULTS: A total of 1100 patients were screened, of whom 869 were randomly assigned to receive secretin (n = 426) or placebo (n = 443) before ERCP and were evaluated after the procedure for efficacy of secretin. The incidence of pancreatitis in the secretin group compared with the placebo group was 36 (8.7%) of 413 patients versus 65 (15.1%) of 431 patients, respectively, P = 0.004. In the subgroup analysis, secretin was highly protective against post-ERCP pancreatitis for patients undergoing biliary sphincterotomy (6/129 vs 32/142, P<0.001), patients undergoing cannulation of the common bile duct (26/339 vs 56/342, P<0.001), and patients not undergoing pancreatic sphincterotomy (26/388 vs 57/403, P = 0.001). Analysis of the interaction between these groups reveals that the primary effect of secretin prophylaxis was prevention of post-ERCP pancreatitis in patients undergoing biliary sphincterotomy.
CONCLUSIONS: Synthetic secretin reduces the risk of post-ERCP pancreatitis, particularly in patients in undergoing biliary sphincterotomy.
