Conic Cap-Suction Uemr for EN Bloc Resection of Non-Granular Pseudodepressed Colonic Lesion: A Novel Technique When Conventional Snaring is not Possible
Colorectal lesions with a depressed component are difficult to snare and have a high risk of submucosal invasion.
Underwater EMR (Binmoeller, 2012) allows endoscopic resection without previous submucosal injection as the colonic lesion “floats” in a lumen filled with water.
We present a case of a 16mm non-granular 0-IIa+IIc lesion located in the sigmoid colon. UEMR was tried but it was not possible to snare the lesion.
Thereafter, with the lumen filled with water, a conic cap was used to gently aspirate the 0-IIc component, facilitating the infolding of the lesion and it was easily snared and resected by UEMR.
