Abstract/OtherAbstract:
BACKGROUND AND STUDY AIMS: Failed biliary cannulation occurs in up to 10% of patients undergoing ERCP. There is some controversy as to the safety and efficacy of using precut techniques to achieve biliary cannulation in difficult cases. To date, no randomized trial has compared the success and complication rates of precut with the rates for persistence when biliary cannulation is difficult. The aim of this study was to compare the success rates and complication rates of precut with the success rates and complication rates of persistence in cases of difficult biliary cannulation. PATIENTS AND METHODS: Patients without prior sphincterotomy who required biliary cannulation were screened. A "difficult biliary cannulation" was arbitrarily defined as failed cannulation after 12 minutes. These patients were then randomized to continue treatment by needle-knife cut over the roof of the papilla or by persistence with a non-wire-guided, single-lumen papillotome. "Primary" success was defined as deep cannulation within 15 minutes of randomization. Primary and final success rates and complication rates within 30 days after ERCP were compared. RESULTS: Over a 38-month period a total of 642 patients were screened. Patients in whom biliary cannulation was successful within a time period of 12 minutes or less formed the reference group (n = 580). The remainder of the patients were randomly assigned to the "precut" arm (n = 32) or to the "persistence" arm (n = 30). Primary success rates and complication rates were similar in the precut and persistence arms (75% and 4% respectively for the precut arm vs. 73% and 9% for the persistence arm). The final successful cannulation rate in the entire group of 642 patients was 99.5%. CONCLUSIONS: In experienced hands, precut papillotomy and persistence in cannulation are equally effective in cases of difficult cannulation, with a similar complication rate.
