镍钛记忆合金网状内支架治疗食管狭窄

Nitinol Stent for the Relief of Esophageal Stenosis

目的食管腔内放置镍钛记忆合金网状内支架，持续扩张食管、贲门部狭窄，改善患者饮食通道。方法利用内支架置放器等器械在Ｘ线下行食管狭窄扩张后放入适当长度的内支架。术后及２天、１月摄Ｘ线片对照。结果２８例均放置成功。术后定期复查，内支架膨胀、固定良好，内径最窄处平均直径１．３ｃｍ。２６例术后吞咽困难即消失。术后死亡９例，平均存活７个月。结论该术式简便、痛苦小、并发症少，解除梗阻快，有效地提高了患者生存质量。

Objective To restore the esophageal lumen by inserting nitinol stent into the narrow site of the esophagus. Methods Nitinol stents were inserted under fluoroscopic guidance into the stenotic site after balloon dilation of the esophageal stenosis.X ray films were taken two days and one month later. Results The procedures were technically successful in all 28 patients.The stent expanded and fixed satisfactorily.The average diameter of the narrowest sites was 1 3cm.Dysphagia disappeared in 26 patients immediately after placing the stent.The average survival time was 7 months in follow up. Conclusion This process in simple,less painful to the patient with fewer complications and quick relief of dysphagia,so that the life quality can be improved and the life time of the patient can be prolonged.
