Peristaltic Contractions Help Snaring During Underwater EMR of Colonic Non-Granular Pseudodepressed LST
En bloc resection of LST-NG pseudodepressed type is mandatory due to a high-risk of submucosal invasion. Sometimes it might be difficult to snare these lesions. During Underwater EMR (UEMR) the colonic lesion “floats” in a lumen filled with fluid and muscularis propria retains a circular configuration and does not follow involutions of the mucosa and submucosa even during peristaltic contractions.
We present 2 cases of 0-IIa+IIc LST-NG resected by UEMR during peristaltic contraction, allowing en bloc resection due to infolding of the lesions.
UEMR during peristaltic contraction may be helpful for en bloc resection of 2cm non-granular LST.
