目的 研究记忆合金自体膨胀支架,治疗高位食管狭窄的方法和措施。方法 采用内镜下同轴扩张并安放记忆合金支架,治疗高位食管狭窄25例,化学烧伤1例,食管病术后复发3例,吻合口狭窄1例,食管病狭窄20例。其中1例能进半流质,10例仅能进流质,14例吞咽唾液困难完全不能进食(包括4例在咽呛咳者),在25例中有5例伴有声音嘶哑,1例失声,4例肺炎,3例气管、支气管炎。结果 25例安放支架者中,24例一次性安放成功,1例第二次安放成功。安置后,4例可正常进食,19例能进半流质,1例进食无明显改观,1例第三天因呼吸困难取出支架,治疗前后分级与症状改善有非常显著的差异。结论 内镜下记忆合金支架安置术可以迅速解除高位食管狭窄,恢复进食通道,减少肺部感染机率,提高生存质量。
Objective To study the methods and measures of self-expandable stent of memory alloy for the treatment of high esophageal stenosis. Methods Twenty-five cases of upper esophageal stenosis, one case of chemical burn, three cases of esophageal disease recurrence, one case of anastomotic stenosis and 20 cases of esophageal stenosis were treated by coaxial expansion with endoscope and memory alloy stent. Among them, 1 patient was able to enter the semi-liquid, 10 patients only into the liquid, 14 patients with difficulty swallowing saliva can not eat (including 4 cases of pharyngeal choking), 5 of 25 cases accompanied by hoarseness, 4 cases of pneumonia, 3 cases of trachea and bronchitis. Results Twenty-five cases of stent placement were successfully placed in one operation, and the other one was placed in the second. After placement, 4 cases can eat normally, 19 cases can enter semi-liquid, 1 case did not change significantly. One case took stent on the third day because of dyspnea. There was a very significant difference between before and after treatment. Conclusion Endoscopic stent-grafting can quickly relieve esophageal stenosis, restore the feeding channel, reduce the risk of pulmonary infection and improve the quality of life.
