摘要： 目的通过分析食管支架置入失败的原因，探讨支架再置入的技术改良和置入效果。方法根据支架置入失败的不同病情
特点，选择更适当的食管支架类型，采用改良的置入技术，对32例次患者进行食管支架再次置入术，观察置入效果并随访。结
果本组支架再置入术成功率96.9%，有效解决了食管狭窄和食管瘘的问题；在半年随访期内，出现支架移位4例，占12.5%，出现
再置入支架上缘食管瘘2例，发生率为6.3%，未见支架脱落、大出血、狭窄等情况。结论改良的食管支架再置入技术可有效解
决支架置入失败后的再置入难题，同时解决相关的食管疾病，减少食管支架置入并发症的发生。

Abstract: ObjectiveTo analyze the causes of failure of esophageal stent implantation and explore technical improvement of
re-implantation of esophageal stent (RIES).MethodsAccording to the conditions of the failed stent implantation,32patients
who required RIES underwent placement of more appropriate esophageal stents with an improved implantation technique.
The patients were followed up for6months after the operation to evaluate the effects of RIES.ResultsThe success rate of the
operation was96.9% in these cases, and the esophageal conditions including stricture and fistula were effectively relieved.
During the6-month follow-up, stent migration occurred in 4cases (12.5% ), and esophageal fistula in the upper edge of the
re-implanted stent occurred in2cases. No stent loss, bleeding, or stricture was found in these cases.ConclusionThe improved
technique is effective for stent re-implantation after failed esophageal stent implantation with reduced complications
associated with esophageal stenting.
