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 [(, ), 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.
评估食管支架套叠术（SIS）在难治性食管自膨式金属支架（SEMS）患者中的安全性和有效性。病例系列研究。对2015年6月至2021年6月在东南大学附属中大医院接受SIS技术治疗的难治性食管SEMS患者进行回顾性分析。分析支架取出成功率和不良事件发生率。共纳入12例患者，其中男性7例，女性5例，年龄50 - 73（62.7±8.5）岁。内支架临床成功率为12/12，中位留置时间为[(, ), 64.5（52.0, 90.8）]天。术后移位率和严重狭窄发生率分别为1/12和3/12。所有患者均在内镜检查一次时成功取出食管支架。SIS术后所有患者均出现少量黏膜外渗，随访90天无患者死亡。
