Colorectal Endoscopic Submucosal Dissection (Cr-Esd), Knife-Assisted Snare Resection (Kar) And Recurrence Rate: A Prospective Cohort Study In Spain

Performing CR-ESD is gradually increasing in Western countries. However, the procedure remains challenging in this setting and surveillance studies outside the Asian countries are not fully described. Additionally, a novel technique of knife-assisted snare resection (KAR) for CR tumors has been recently reported. However, some of the latter eventually require a piecemeal resection (p-KAR). A comparison between these two techniques is lacking.
