内支架治疗食管癌性狭窄及瘘的临床应用

目的探讨国产自膨式覆膜金属内支架治疗食管癌并发食管狭窄及瘘的临床应用价值。方法对29例食管癌并发食管狭窄及食管瘘患者在X线透视监视下经口置入国产自膨式覆膜金属内支架。其中晚期食管贲门癌性狭窄3例,食管癌放疗后狭窄9例,食管癌或贲门癌术后吻合口狭窄12例,食管癌并发食管气管瘘或食管纵膈瘘5例。结果29例患者共置入内支架31枚,所有病例均一次成功,技术成功率100%。未发生与操作有直接关系的并发症。所有患者支架留置后,吞咽困难立即改善,生存质量提高;6例并发食管气管瘘或食管纵膈瘘者瘘口立即封闭。随访1～12个月,1例内支架移位30mm以上,另1例内支架滑入胃内,这两例患者分别再次叠放支架;3例死亡,其中2例死于晚期食管贲门癌,1例死于食管大出血;4例支架置入后再狭窄;1例因支架端口磨损引起食管-气管瘘。结论虽然金属内支架是一种开通食管、闭塞瘘口的简便、安全、有效的方法,但是应用食管内支架治疗食管癌性狭窄及瘘之前,充分了解可能发生的并发症及处理方法极为重要。

Clinical application of metallic stents in treatment of esophageal strictures and fistulae secondary to carcinoma

Objective To explore the clinical value of the self-expanding metal covered stents that made in China for the treatment of esophageal strictures and fistulae secondary to carcinoma.Methods Of 29 patients collected in our study,the strictures were caused by advanced esophageal carcinoma(n=3),post-radiotherapy strictures(n=9),post operative anastomotic strictures(n=12),as well as 5 patients with esophageal-tracheal fistula or esophgomediastinum fistula.The stents were implanted through mouth under X-ray fluor...
