【摘要】 目的　探讨食管支架术对儿童腐蚀剂损伤性食管狭窄及溃疡的治疗方法 ,维持进食通道 ,此后再去除支架。方法　 12例病例采用改进的“Z”型不锈钢被膜支架或镍钛记忆合金网状支架 ,利用气管支架输送器经口放置支架。结果　 12例初次共放置18枚“Z”型不锈钢被膜支架 ,均缓解了进食困难的症状 ,术后随访观察 0 .5～ 6年 ,9例经 1次至多次调整或更换支架 ;5例支架去除后观察 0 .5～ 3年 ,进食正常 ;1例高位食管狭窄行外科手术 ;6例支架尚未取出 ,能进普食或软食。 1例放置镍钛记忆合金网状支架2枚 ,术后 1月出现再狭窄 ,6年后手术切除。结论　使用“Z”型被膜支架治疗食管腐蚀剂损伤后狭窄、溃疡等较为安全、并发症少、效果较好更多还原

【Abstract】 Objective To study the method of treatment of esophageal stricture and ulcer in children caused by corrosive injury using esophageal stent.Methods The stent made of stainlees steel Z type covered with thin membrane or Ni-Ti shape memory wire mesh-like stent was used and placed through mouth by the transport of tracheal stent in 12 cases.Results Symptoms of the dysphagia in all 12 cases treated with 18 sets of Z stents were alleviated remarkably.Following up study from 6 month to 6 years,the stents were regulated or replaced one or more times in 9 cases,the stents were removed in 5 cases,and food-taking was normal following up from 6 to 36 months.Surgical operation was done in one case.The stents were retained in 6 cases,but ordinary and soft food could be taken without problem.One case was treated with 2 stes of Ni-Ti shape memory wire mesh-like stent,the esophageal stricture reappeared one month later and operation was done 6 years later.Conclusion Stent of the Z type is safe and effective in treating esophageal stricture and ulcer in children caused by corrosive injury.更多还原
