目的评价记忆合金内支架治疗食管及贲门部良恶性狭窄的效果。方法按常规胃镜检查操作，经引导钢丝予软管扩张器对狭窄部位先施扩张术，再经胃镜及Ｘ线对狭窄段行双重定位。后置入金属内支架（Ｓｔｅｎｔ），１０例共置入支架１２枚。结果内支架置入全部成功，术后患者狭窄全部得到改善，但贲门失弛缓患者出现了严重反流性食管炎。结论记忆合金内支架是治疗食管及贲门部恶性狭窄的有效的非手术方法，可明显改善患者的生存质量。而良性狭窄患者，似应以暂时性内支架置入术为好。
Objective To evaluate the effect of memory alloy stents in the treatment of benign and malignant stenosis of the esophagus and cardia. Methods According to routine gastroscopy operation, the guide wire to the hose dilator was applied to the expansion of the stenosis site, followed by gastroscopy and X-ray double-line positioning of the stenosis. After the stent into the metal (Stent), 10 cases were placed in a total of 12 stent. Results All the stents were inserted successfully, and all the patients’ stenosis was improved after operation. However, severe reflux esophagitis occurred in patients with cardiac achalasia. Conclusion The memory alloy stent is an effective non-surgical treatment of malignant stenosis of the esophagus and cardia, which can significantly improve the quality of life of patients. In patients with benign stenosis, it seems to be temporary stent placement is better.
