Endoscopic Resection Effective for SSPs ≥10 mm in Meta-analysis; Cold EMR May Be Best
Douglas K. Rex, MD, FASGE reviewing Chandrasekar VT, et al. Clin Gastroenterol Hepatol 2019 Nov 28.
This systematic review and meta-analysis identified 911 patients with 1137 sessile serrated polyps (SSPs) ≥10 mm in 14 studies, in which resection was performed by hot EMR in 8 studies, hot EMR and a second technique in 2, cold EMR in 2, and standard snare resection in 1. Overall, technical success was 99.5%, with a rate of residual polyp at follow-up of 4.3%, which was related to lesion size: 5.9% for lesions ≥20 mm and 1.2% for 10- to 19-mm lesions. The perforation rate was 0.3%, and the overall delayed hemorrhage rate was 1.3%, but there were no delayed hemorrhages with cold EMR. Residual polyp rates were numerically lower with cold EMR.
COMMENT
Given the limitations of a systematic review and meta-analysis, these data suggest that cold EMR is as effective as hot EMR for resection of SSPs ≥10 mm, yet safer. A direct comparison of hot and cold EMRs for serrated lesions is warranted.
