摘 要：BACKGROUND Large appendiceal orifice polyps are traditionally treated ***,endoscopic mucosal resection(EMR)and endoscopic submucosal dissection(ESD)have been utilized as alternative resection *** To evaluate the efficacy and safety of endoscopic resection techniques for the management of large appendiceal orifice *** This was a retrospective observational study conducted to assess the feasibility and safety of EMR and ESD for large appendiceal orifice *** project was approved by the Baylor College of Medicine Institutional Review *** who underwent endoscopic resection of appendiceal orifice polyps≥1 cm from 2015 to 2022 at a tertiary referral endoscopy center in the United States were *** main outcomes of this study included en bloc resection,R0 resection,post resection adverse events,and polyp *** A total of 19 patients were *** patients were female(53%)and Caucasian(95%).The mean age was 63.3±10.8 years,and the average body mass index was 28.8±*** mean polyp size was 25.5±14.2 mm.74%of polyps were localized to the appendix(at or inside the appendiceal orifice)and the remaining extended into the cecum.68%of polyps occupied≥50%of the appendiceal orifice *** mean procedure duration was 61.6±37.9 *** were resected via endoscopic mucosal resection,endoscopic submucosal dissection,and hybrid procedures in 5,6,and 8 patients,*** pathology was remarkable for tubular adenoma(n=10)[one with high grade dysplasia],sessile serrated adenoma(n=7),and tubulovillous adenoma(n=2)[two with high grade dysplasia].En bloc resection was achieved in 84%with an 88%R0 resection *** the large polyp sizes and challenging procedures,89%(n=17)of patients were discharged on the same day as their *** patients were admitted for post-procedure observation for conservative pain *** patients underwent repeat colonoscopy without evide
