Previous studies have indicated that cold snare polypectomy effectively removes colorectal lesions up to 15 mm in size but cuts more superficially than hot snare polypectomy. Understanding the relative depth of resection is important, particularly when encountering lesions with the potential for cancer, where a deeper depth of resection is preferred. <\/p>\n\n\n\n
In a study of consecutive 6- to 9-mm lesions without endoscopic features of cancer, 53 lesions were removed, including 13 excluded from the study because of challenges in measuring resection depth. Of 14 lesions removed by cold snare polypectomy, muscularis mucosa (MM) was present in 57% and submucosa (SM) in 29%. Of 12 lesions removed by hot snare polypectomy, MM was present in 92% and SM in 83%. Of 14 removed by underwater EMR (UEMR), MM and SM were present in 100% and 100%. The mean thickness of resected SM tissue was 52 microns with cold snare, 623 microns with hot snare, and 1119 microns with UEMR.<\/p>\n","protected":false},"excerpt":{"rendered":"
