Effectiveness of a multi-loop traction device for colorectal endoscopic submucosal dissection performed by trainees:...

Area of Science:

• Gastroenterology
• Surgical Innovation
• Medical Education

Background:

• Colorectal endoscopic submucosal dissection (ESD) is a complex procedure with a debated training pathway.
• Current training often requires prior animal or upper gastrointestinal ESD experience.

Purpose of the Study:

• To compare outcomes of colorectal ESD performed by trainees using the multi-loop traction device (MLTD) versus conventional ESD by experts.
• To assess the MLTD's safety and efficacy in introducing colorectal ESD to novice endoscopists.

Main Methods:

• A pilot study comparing 13 patients treated with MLTD-assisted trainee ESD to 13 patients treated with conventional expert ESD.
• Data collected included procedure time, dissection speed, and intraoperative perforation rates.

Main Results:

• No significant differences were observed in procedure time (50 min vs. 30 min) or dissection speed (19.9 mm²/min vs. 28.7 mm²/min).
• Intraoperative perforation rates were 0% in both groups. Trainees achieved 100% ESD self-completion using the MLTD.

Conclusions:

• The MLTD facilitates the safe introduction of colorectal ESD to trainees lacking prior colorectal ESD experience.
• The MLTD may serve as a viable alternative to animal or upper GI ESD training for colorectal ESD novices.
