The aim of this case series study was to evaluate the feasibility, safety, and effectiveness of ETA for lesions at the appendiceal orifice.<\/jats:p><jats:p>\n            Methods\u2002This retrospective study included consecutive patients with appendiceal orifice lesions who underwent ETA between December 2018 and March 2021.\u200aThe primary outcome was technical success. The secondary outcomes included postoperative adverse events, postoperative hospital stay, and recurrence.<\/jats:p><jats:p>\n            Results\u200213 patients with appendiceal orifice lesions underwent ETA during the study period. The median lesion size was 20\u200amm (range 8\u201350). Lesions morphologies were polypoid lesions (n\u200a=\u200a5), laterally spreading tumors (n\u200a=\u200a4), and submucosal lesions (n\u200a=\u200a4). Technical success with complete resection was achieved in all 13 cases. There were no postoperative bleeding, perforation, or intra-abdominal abscess. The median length of hospital stay after ETA was 8 days (range 6\u201318). There was no tumor recurrence during a median follow-up of 17 months (range 1\u201328).<\/jats:p><jats:p>\n            Conclusions\u2002ETA is feasible, safe, and effective for complete resection of appendiceal orifice lesions.
