目的 镍钛合金支架置入术治疗食管狭窄 49例情况分析。方法 回顾性分析 49例、5 2根镍钛支架植入术前、术后病例的临床资料。术后疗效观察 3个月者 39例 ,6个月者 38例 ,12个月者 2 0例 ,8例观察 18个月。结果 49例病人支架全部顺利置放。病人吞咽困难均得到缓解 ,其中 3例食管支气管瘘病人瘘口均得到封闭可解除呛咳和进食困难 ,治疗效果明显。支架置入术后 6个月内易发生异物堵塞 ,6个月以上瘤体堵塞多见 ,均可经胃镜治疗缓解。结论 镍钛合金支架置入术治疗食管狭窄效果良好 ,以被覆镍钛合金支架为好。
Objective To investigate the treatment of 49 cases of esophageal stenosis with Ni - Ti alloy stent implantation. Methods The clinical data of 49 cases and 52 cases of nickel-titanium stent implantation before and after the operation were retrospectively analyzed. There were 39 cases in 3 months after operation, 38 cases in 6 months, 20 cases in 12 months and 8 months in 18 cases. Results 49 cases of patients with all the smooth stent placement. Patients with dysphagia were eased, of which 3 cases of esophageal fistula patients were closed closed to relieve cough and eating difficulties, the treatment effect is obvious. Stent 6 months after implantation prone to foreign body blockage, more than 6 months of tumor blockage more common, can be relieved by gastroscopy. Conclusion Nitinol stenting is effective in treating esophageal stenosis, and nickel-titanium alloy stents are better.
