“…Although ASEMR in the present study shows a slightly higher complete resection rate (94.1%) than UEMR in the previous study, a head-to-head comparison based on two different studies is not appropriate. Theoretically, given that most rectal NETs invade the submucosa, the lack of submucosal fat tissue beneath the NETs may restrict the tissue buoyancy for UEMR 27 . However, this theoretical limitation may not affect the completeness of resection in UEMR because UEMR can facilitate en bloc snaring of NETs by avoiding distension of rectal lumen.…”

“…By removing intraluminal air, colonic wall tension is decreased, and water insufflation naturally separates the mucosal layer from the muscularis propria thereby eliminating the need for a submucosal injection. This can also potentially allow the capture of a larger mucosal surface area in the opened snare 45 . e. Colon spasms can make the process of polypectomy difficult and painful.…”

“…In combination, layer separation and thermal dissipation are thought to decrease the risk of early and delayed perforation. 13 Although data from large-scale studies are not available, the usefulness of underwater EMR for complete resection and safety for adenomas 20 mm or smaller 14 or for lesions with biopsy scars 15 have been reported.…”
