Transpancreatic precut papillotomy (TPPP) or Double-guidewire (DG) cannulation is often indicated in failed standard biliary cannulation (BC). Both methods require experienced endoscopists, and contains risk in some degree. However, both methods might be useful after failed standard BC. We aimed to compare success rate, and complication rates between the two techniques in this randomized controlled study.
Safety,Efficacy
1)Success rate in biliary cannulation
2)The rate of post-ERCP pancreatitis, the severity of the pancreatitis
1)Cannulation time
2)Other complication rates such as bleeding, perforation, cholangitis
