支架内套支架技术移除难取性食管自膨式金属支架的安全性和有效性分析

Safety and efficacy analysis of the removal of refractory esophageal self‑expandable metal stents by stent‑in‑stent technique

探讨食管支架内套支架(SIS)技术应用于移除难取性食管自膨式金属支架(SEMS)的安全性和有效性。病例系列研究。回顾性分析2015年6月至2021年6月在东南大学附属中大医院应用SIS技术诊治的难取性食管SEMS患者,分析支架取出成功率及不良事件发生情况。共纳入12例患者,男7例,女5例,年龄50~73(62.7±8.5)岁。内侧支架置入术临床成功率为12/12,中位留置时间为[M(Q_(1),Q_(3)),64.5(52.0,90.8)d],术后移位率及重度狭窄发生率分别为1/12和3/12。所有患者的食管双支架均一次性成功取出。所有患者SIS术后均出现黏膜少量渗血,随访90 d,无患者发生手术操作相关性死亡。

To evaluate the safety and efficacy of esophageal stent‑in‑stent(SIS)in patients with refractory esophageal self‑expandable metal stents(SEMS).Case series study.Retrospective analysis was made on the patients with refractory esophageal SEMS treated with SIS technology in Zhongda Hospital Affiliated to Southeast University from June 2015 to June 2021.The success rate of stent removal and the incidence of adverse events were analyzed.A total of 12 patients were included,including 7 males and 5 females,aged 50‑73(62.7±8.5)years.The clinical success rate of the internal stents was 12/12,with the median retention time of[M(Q_(1),Q_(3)),64.5(52.0,90.8)]days.The postoperative displacement rate and severe stenosis incidence were 1/12 and 3/12,respectively.The esophageal stents were successfully removed in one endoscopic session in all patients.A small amount of mucous membrane extravasation occurred in all patients after SIS,and no patients died after 90 days of follow‑up.
