Pseudodepressed NG LST have to be resected en bloc due to an elevated risk of deep submucosal invasion. We present the case of a 85 years old patient referred for endoscopic resection of a pseudodepressed NG LST of more than half of the circular wall of the ascending colon with previous biopsy showing high-grade dysplasia, and no endoscopic signs of deep submucosal invasion.

Herein (video) we show a modified technique with underwater EMR to allow en bloc resection, using a 25 mm rounded snare.

Patient was discharged the same day after 1 hour observation. Final histology showed high grade dysplasia.
