临时食管支架植入治疗小儿食管化学性损伤狭窄

目的探讨临时食管金属记忆支架植入术治疗小儿食管化学性损伤狭窄的临床疗效。方法选择10例小儿食管化学性损伤狭窄患者，在X线引导下置入食管金属记忆支架，4周后在内镜引导下取出支架。术后密切观察疗效及并发症。结果支架术后4周，所有患者吞咽困难均显著改善。术后平均随访时间为12个月，2例患者于术后6、8个月因肉芽瘢痕组织增生而导致狭窄再行食管扩张术，其余8例患者未再行食管扩张术。结论食管金属记忆支架植入术治疗小儿食管化学性损伤狭窄有较好的临床疗效，长期疗效有待进一步观察。

Temporary Esophageal Stent Placement in Children with Esophageal Stenosis of Chemical Damage

ObjectiveTo appraise the clinical efficacy of temporary esophageal stent in the treatment of esophageal stenosis from chemical (damage) in children.MethodsTen patients with esophageal stenosis of chemical damage were enrolled. The esophageal metallic stent was placed under the guidance of X-ray. After 4 weeks, the esophageal metallic stent was taken under the guidance of endoscopy. The clinical effectiveness and complications were closely observed after stenting during follow-up.ResultsWithin the postoperative 4 weeks, dysphagia was much improved in all patients. The average follow-up periods after stenting was 12 months. Two patients with esophageal stenosis had restenosis 6 months and 8 months after stenting because of hyperlastic granulation tissues by balloon expansion. The rest 8 patients had not been treated again by balloon expansion.ConclusionTemporary esophageal metallic remember stent in the treatment of esophageal stenosis of chemical damage in children has a satisfied clinical efficacy, and needs to be further evaluated.
