Endoscopic retrograde cholangiopancreatography (ERCP) is a technically challenging procedure. It takes time to learn the basic skills and need at least 180 - 200 cases for trainees to achieve competency in ERCP. Hands-on practice in patients remains the gold standard for ERCP training. Traditional hands-on ERCP training requires the trainer to be on-site to assist the trainee with ERCP operations. We hypothesized that the trainee can be safely guided by trainer off-site with interactive audio and endoscopic and fluoroscopic view. Technology-enabled health care at a distance has profound scientific potential and accordingly has been met with growing interest. Teleguidance facilitated ERCP cannulation is a strategy to provide expert cannulation guidance to trainee in settings where such expertise is not on-site. Teleguidance not only reduces unnecessary radiation exposure of endoscopist, but also provides remote assistance for trainees to complete training or further improve skills. Given the advantages of the off-site teleguidance, it could be an attractive substitute for on-site hands-on ERCP training. The primary aim of this study was to evaluate whether off-site assistance (Off group) could achieve a comparable success rate to on-site assistance (On group) regarding the rates of successful selective biliary cannulation during ERCP training.
