摘要
目的:探讨镍钛记忆合金(NTSMA)支架在治疗食管狭窄中的应用价值。方法:在X线下了解食管狭窄的部位,经食管镜插入金属导丝,先行食管扩张术,再将装有支架的置入器沿导丝滑入食管狭窄处,放出NTSMA支架,并让其自行复形,术后X线吞钡复查了解支架位置和通畅情况。结果:19例食管狭窄患者,安放支架均一次成功,恢复进食功能,近期有效率为100%。结论:NTSMA支架可使狭窄的食管迅速扩张,明显地改善进食困难,具有使用方便、见效快、疗效可靠及无严重并发症等优点,可以作为治疗食管狭窄的常规手段之一。
Objective:To discuss the use of Ni Ti shape memory alloy stand in treating the stricture of esophagus.Method:After finding the stricture part of esophagus under X ray, the metal guide string was put through the esophagoscope. Dilatation of esophagus was performed firstly. Then the inserting instrument,which has the Ni Ti shape memory alloy stand inside,was put through the stricture part along the metal guide string and the stand which can return to its original shape automatically was released. Barium meal examination of esophagus was performed after the opeartion to determine the site of the stand and to realize the smooth degree of esophagus.Result:All 19 patients got a successful operation at one time.They swallowed freely after the operation. The effective rate was 100%.Conclusion:Ni Ti shape memory alloy stand can dilate the stricture of esophagus quickly, improve swallowing function obviously. The operation can be easily performed. The therapeutic effectiveness is reliable,and there is no serious complication. This can be used as a routine method in treating the stricture of esophagus.
