Endoscopic submucosal dissection and radiofrequency ablation for patients with flat‐type esophageal squamous cell neoplasia

摘要

Abstract Several studies have demonstrated that endoscopic submucosal dissection (ESD) and radiofrequency ablation (RFA) are effective for patients with flat‐type esophageal squamous cell neoplasia (ESCN). In the present study, we aimed to report the outcomes achieved using these two endoscopic treatments. Patients who underwent ESD or RFA for flat‐type ESCN at Kaohsiung Chang Gung Memorial Hospital between January 2011 and December 2016 were included in this retrospective chart review. Treatment outcome, procedure time, and complication and recurrence rates were compared. Among 35 patients with flat‐type ESCN enrolled, 31 were treated with ESD and 4 with RFA. Overall mean age was 58.34?±?11.5?years; 32 patients were men and 3 were women. The mean procedure times were 138.13?±?101.47?minutes for ESD and 26.75?±?11.1?minutes for RFA (P?
