Brief Summary

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.

Study Arms (2)

Off-site assistance group

EXPERIMENTAL

The trainer supervised the trainee's cannulation operation outside the procedure room through a high-definition screen displaying the endoscopic and fluoroscopic view. The trainer was allowed to provide unlimited verbal instructions to the trainee by an intercom. The trainer was not allowed to enter the procedure room and touch the endoscope or accessories until the trainee ask for help or failed to achieve deep biliary cannulation. The trainer would halt and correct the trainee's inappropriate maneuvers immediately to avoid unnecessary papillary trauma and potential complications. Then the trainer would then take over and continue with the cannulation.

Procedure: Off-site assistance

On-site assistance group

NO INTERVENTION
