Letter to editor: piecemeal cold snare polypectomy versus conventional endoscopic mucosal resection for large sessile serrated lesions

With great interest, we read the recent study by van Hattem et al , which compared the utility in large sessile serrated lesions (L-SSL) management between piecemeal cold snare polypectomy (p-CSP) and endoscopic mucosal resection (EMR).1 We congratulate the authors for this innovative study that demonstrated the security and effection of p-CSP in the management of L-SSL and opened the door to determine the best treatment for endoscopically resecting L-SSL. Although the data and methodology of the study are impressive, there are several questions, which should be highlighted. First, this study divided patients with L-SSL at two different times into p-CSP and EMR group. Compared with the early stage, with …
