Tu1041 RANDOMIZED CONTROLLED TRIAL OF NEEDLE-KNIFE FISTULOTOMY VERSUS TRANSPAPILLARY CANNULATION FOR PRIMARY BILIARY ACCESS DURING ENDOSCOPIC RETROGRADE CHOLANGIO-PANCREATOGRAPHY PERFORMED BY ADVANCED ENDOSCOPY TRAINEES.

Needle-knife fistulotomy (NKF) is a technique traditionally used to achieve biliary access when transpapillary cannulation techniques are unsuccessful. The literature supports that NKF can be safely performed as a primary biliary access approach but due to technical aspects, this technique should be reserved for expert endoscopists. The aim of this study was to evaluate the efficacy and safety of NKF compared to standard transpapillary access when performed by trainee endoscopists.
