Difficult cannulation during endoscopic retrograde cholangiopancreatography-needle-knife precut versus transpancreatic sphincterotomy on the basis of successful cannulation and adverse events.

ABSTRACT:

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 (TPS) and precut sphincterotomy (PCS).

Methods

Data from the Swedish Registry for Gallstone Surgery and ERCP (GallRiks), collected from 2011 to 2022, were analyzed. A total of 105,303 ERCP procedures were recorded in GallRiks during the study period. After exclusions, the study population consisted of 47,486 ERCP procedures. Of these, 4547 received PCS and 3273 received TPS. The remaini
