摘要
目的评价国产可回收食管覆膜金属内支架治疗贲门失弛缓症的临床疗效。方法对16例临床诊断为贲门失弛缓症的患者,在DSA监视下经口腔置入"Z"型双喇叭口覆膜金属内支架,28d左右进行食管造影并回收内支架。结果16例中1例于术后2周支架脱落入胃腔内,经取出重新放置成功;所有病例在28d左右顺利取出,未出现严重并发症;随访3个月～3年,2例分别于术后1、1.5年出现再狭窄,经球囊扩张好转。所有患者无吞咽困难等临床症状。结论可回收食管覆膜金属内支架治疗贲门失弛缓症,具有操作简便、安全、效果显著、并发症少、再狭窄率低等优点。
Objective To evaluate the clinical effect of retrievable esophageal covered metal internal stent in treating patients with achalasia.Methods Under DSA guidance,peroral＂Z-type＂double horn covered metal internal stent implantation was performed in 16 patients with achalasia.Esophagography was carried out about 28 days after the procedure and the stent was retrieved.Results Of 16 cases,the stent fell off into the stomach two weeks after the operation in one.And the stent was successfully replaced after it was taken out.The placed stent was successfully retrieved in all cases 28 days after the treatment.No serious complications occurred.All the patients were followed up for 3 months to 3 years.During the follow-up period restenosis of the esophagus developed in two cases（at one and 1.5 years respectively）,and the restenosis degree was relived after balloon dilation.Clinically,no esophageal symptoms,such as dysphagia,occurred in all patients.Conclusion As a simple and safe technique,the retrievable esophageal covered metal internal stent implantation is very effective with fewer complications for the treatment of achalasia.Moreover,the technique carries lower restenosis occurrence.
