全覆膜金属支架在内镜全层切除食管及贲门近食管段巨大黏膜下肿瘤中的临床应用

目的 评价内镜下全层切除（EFTR）食管及贲门近食管段巨大黏膜下肿瘤（SMTs）后应用全覆膜可回收金属支架处理巨大创面的疗效及安全性。方法 20例于2017年7月至2021年7月于复旦大学附属中山医院接受EFTR术并于术后放置全覆膜可回收支架的食管及贲门近食管段巨大SMTs患者，对其治疗效果、术后并发症等结果进行回顾性分析。结果 20例食管及贲门近食管段巨大SMTs患者接受EFTR术后出现应用常规内镜缝合技术无法完全修补及封闭的创面，均予置入全覆膜可回收金属支架，2-3周后取出，创面修复良好，未出现严重并发症。结论 全覆膜可回收金属支架在修补及封闭食管及贲门近食管段巨大SMTs行EFTR术后巨大创面安全有效。

Application of covered metal stents in endoscopic full-thickness resection of large submucosal tumor of the esophagus and proximal esophageal segment of cardia

Objective To evaluate the efficacy and safety of endoscopic full-thickness resection (EFTR) of large submucosal tumors (SMTs) in the esophagus and proximal esophageal segment of cardia. Methods From July 2017 to July 2021, 20 patients with large SMTs in the esophagus and proximal esophageal segment of cardia who underwent EFTR and placed covered metal stents in Zhongshan Hospital of Fudan University were analyzed retrospectively. Results 20 patients with large SMTs in the esophagus and proximal esophageal segment of cardia had wounds that could not be completely repaired and closed by conventional endoscopic suture after EFTR. They were treated with fully covered metal recyclable stents and removed after 2-3 weeks. The wounds were repaired well without serious complications. Conclusion The covered metal stents are safe and effective in repairing and sealing huge wounds after EFTR.
