目的:探讨国产自膨式镍钛记忆合金食管支架在食管、贲门良恶性狭窄及食管瘘中的临床应用并观察疗效。方法:收集我院2005年11月~2008年8月采用胃镜辅助置入镍钛记忆合金食管支架的患者108例,其中男90例,女18例,年龄37~88岁;包括食管癌性狭窄41例,贲门癌性狭窄5例,放疗后狭窄1例,肺癌压迫致食管狭窄1例,食管、贲门癌术后吻合口顽固性狭窄21例,食管癌术后复发致狭窄6例,食管瘘33例。结果:108例患者共置入食管支架116枚,一次性置入成功率100%,置入后患者吞咽梗阻的症状有不同程度的改善,呛咳的症状基本消失。结论:食管支架置入操作简单、安全,成功率高,是治疗食管良恶性狭窄及封堵瘘口的有效方法。
OBJECTIVE: To investigate the clinical application of homemade self-expanding NiTi memory alloy esophageal stent in esophageal and cardial benign and malignant stenosis and esophageal fistula and to observe the curative effect. Methods: A total of 108 patients (n = 90) and 18 females (aged 37-88 years) were enrolled in our hospital from November 2005 to August 2008 with gastroscope assisted placement of NiTi memory alloy esophageal stents. Esophageal cancer stenosis 41 cases, 5 cases of gastric cancer stenosis, 1 case of stenosis after radiotherapy, 1 case of esophageal stenosis caused by compression of lung cancer, 21 cases of intractable stenosis of esophagus and cardiac cancer, 6 cases of stenosis after esophageal cancer recurrence, esophageal fistula 33 cases. Results: A total of 116 esophageal stents were placed in 108 patients. The success rate of one-time implantation was 100%. The symptom of swallowing obstruction improved to some extent after implantation, and the symptoms of cough disappeared. Conclusion: Esophageal stent placement is simple, safe and successful. It is an effective method for the treatment of benign and malignant esophageal stenosis and closure of the fistula.
