Gut . 2024 Jul; 73(11):1823-1830. PMID: 38964854
Background And Aims: Conventional hot snare endoscopic mucosal resection (H-EMR) is effective for the management of large (≥20 mm) non-pedunculated colon polyps (LNPCPs) however, electrocautery-related complications may incur significant morbidity....

Clin Gastroenterol Hepatol . 2022 May; 21(1):72-80.e2. PMID: 35526795
Background And Aims: Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are complementary techniques for large (≥20 mm) nonpedunculated rectal polyps (LNPRPs). A mechanism for appropriate technique selection has...

Gastrointest Endosc . 2021 Dec; 95(3):527-534.e2. PMID: 34875258
Background And Aims: Detailed lesion assessment of large nonpedunculated colorectal polyps (LNPCPs; ≥20 mm) can help predict the risk of submucosal invasive cancer (SMIC). Traditionally this has required the use...

Clin Gastroenterol Hepatol . 2021 May; 19(11):2425-2434.e4. PMID: 33992780
Background And Aims: The ability of optical evaluation to diagnose submucosal invasive cancer (SMIC) prior to endoscopic resection of large (≥20 mm) nonpedunculated colorectal polyps (LNPCPs) is critical to inform...

Vosko S, Gupta S, Shahidi N, van Hattem W, Zahid S, McKay O, et al.
Gastrointest Endosc . 2021 May; 94(5):959-968.e2. PMID: 33989645
Background And Aims: The endoscopic management of large nonpedunculated colorectal polyps involving the ileocecal valve (ICV-LNPCPs) remains challenging because of its unique anatomic features, with long-term outcomes inferior to LNPCPs...

Gastroenterology . 2021 Apr; 161(1):163-170.e3. PMID: 33798525
Background & Aims: Thermal ablation of the defect margin after endoscopic mucosal resection (EMR-T) for treating large (≥20 mm) nonpedunculated colorectal polyps (LNPCPs) has shown efficacy in a randomized trial,...

Am J Gastroenterol . 2021 Feb; 116(5):958-966. PMID: 33625125
Introduction: Endoscopic mucosal resection (EMR) is an effective therapy for naive large nonpedunculated colorectal polyps (N-LNPCPs). The best approach for the treatment of previously attempted LNPCPs (PA-LNPCPs) is undetermined. Methods:...
