SCOPE-INDEPENDENT TRANSANAL FLEXIBLE RETRACTION METHOD FOR RECTAL ESD

Video Transcription

Video Summary

This presentation describes a transanal retraction method for rectal ESD using the GelPOINT Path platform with a flexible overtube and grasper. The approach aims to improve exposure of the submucosal plane, allowing safer en bloc resection of sessile rectal adenomas while preserving rectal function. In ex vivo bovine testing, retractor-assisted ESD reduced procedure time by 33%, with fewer lift injections and less lift fluid needed. The authors conclude this independent transanal retraction strategy may make rectal ESD faster, easier, and more widely adopted, reducing reliance on full-thickness excision techniques.
