对比了塑料内支架和记忆合金内支架治疗食管狭窄的疗效和不良反应。采用资料分析、门诊和家庭随访、钡餐、内镜及病理复查,结果两种内支架对食管狭窄均有良好的减症作用,置管后吞咽困难程度分别由平均3.2 度(塑胶组) 和3 .4 度( 记忆合金组) 改善为1.5 度和1 .1 度。5 例食管瘘4 例得到关闭。记忆合金支架容易放置、不易移位,但其近期疼痛较多,远期肉芽增生较多应予以重视 The efficacy and adverse reactions of plastic stent and memory alloy stent in treating esophageal stenosis were compared. Data analysis, outpatient and family follow-up, barium meal, endoscopy and pathological examination showed that both stents had a good reduction effect on esophageal stenosis. The degree of dysphagia after catheterization was increased by an average of 3.2 degrees (plastic group) and 3 .4 degrees (memory alloy group) improved to 1.5 degrees and 1.1 degrees. Four cases of esophageal fistula were closed. Memory alloy stent easy to place, not easy to shift, but the recent pain more, more long-term granulation should be emphasized
