Orthodontic rubber band traction improves trainees’ learning curve of colorectal endoscopic submucosal dissection: a prospective randomized study

Colorectal endoscopic submucosal dissection (ESD) is a technically demanding operation with a long learning curve. The aim of this study was to determine whether orthodontic rubber band (ORB)-assisted colorectal ESD could improve the trainees' learning curve as it was shown to shorten colorectal ESD procedure time in trainees and experts.
