Abstract
BACKGROUND AND AIMS: The EndoRotor, nonthermal, powered endoscopic debridement (PED) instrument (Interscope Inc, Whitinsville, Mass, USA), is a novel device used in the GI tract. It uses adjustable suction and a rotary cutting blade to precisely resect mucosal and submucosal tissue. Our aim was to assess the technical feasibility, safety, and efficacy of PED using the EndoRotor device. METHODS: This was an Institutional Review Board-approved, multicenter, retrospective review. Patients underwent PED with the EndoRotor device from August 2018 to September 2019 at 4 high-volume U.S. centers. Patient demographics, indication for PED, and procedural and histopathologic data were recorded. RESULTS: Thirty-four patients underwent PED (41 lesions). The most common indications for PED were colon polyps (18, 52.9%) and Barrett's esophagus (8, 23.5%). Most lesions (35, 85.4%) were resected previously for the same indication using standard techniques. Technical success was achieved in 97.6% of lesions (n = 40). Clinical success was achieved in most patients who underwent a follow-up examination (19, 79.2%). Intraprocedural bleeding (in 10 patients) was managed endoscopically; no EndoRotor-related perforations occurred. Three postprocedural adverse events occurred: self-limited chest pain in 1 patient and delayed bleeding in 2. CONCLUSIONS: The EndoRotor is a novel, effective, and safe PED device for endoscopic resection of flat and polypoid lesions in the colon and foregut. It may have a promising role in the endoscopic management of naïve and scarred mucosal lesions based on this initial experience. Further prospective studies are needed to clarify its role in endoluminal resection.
