Study of using coated metallic stent in treating malignant esophageal stricture

目的 评价国产被膜网状支架治疗食管癌性狭窄的价值 ,探讨支架置入的相关技术。方法 本组 30例 ,置入支架前 ,行食管造影 ,并用X线显影尺精确定位 ,然后用超滑导丝、导引导管引入超硬导丝 ,对狭窄部扩张后 ,将支架置入预定部位。结果 30例共置入支架 31枚 ,所有病例均一次成功 ,患者吞咽功能明显改善 ,未出现食管穿孔、大出血或死亡等严重并发症。结论 国产被膜网状支架治疗食管癌性狭窄安全、有效 ;相关技术的改进 ,可减少患者不适及并发症 ,提高支架放置的成功率及准确性。

Objective To evaluate the value of using coated metallic stent in treatment for malignant esophageal stricture and to investigate the techniques of placing the stent. Methods This series included 30 cases. The esophagography was made for localizing the position of stricture before stenting. The stents were placed after the stricture had been dilated. Results 31 stents were placed in 30 cases. All stents were successfully placed only for one without serious complications including the rupture of esophagus、massive hemorrhage、death and so on. The symptoms of dysphasia were relieved after the placement procedure. Conclusion Esophageal stent placement is an safe and effective therapy for the treatment of malignant esophageal stricture. The technique would be improved as time goes by with more scientific outcomes.
