Difficult cannulation during endoscopic retrograde cholangiopancreatography—needle-knife precut versus transpancreatic sphincterotomy on the basis of successful cannulation and adverse events
Background: When cannulation is challenging during endoscopic retrograde cholangiopancreatography (ERCP), and the standard guidewire technique with sphincterotomy is unsuccessful, alternative cannulation techniques can be used to access the biliary tree. The purpose of this study was to compare the incidence of adverse events and cannulation success rates between transpancreatic sphincterotomy (TP
