目的　总结食管重建术治疗小儿化学性烧伤后瘢痕狭窄的经验 ,探讨此疗法常见并发症的预防。　方法　本组 2 8例均应用保留横结肠左动脉升支和经胸骨后隧道顺蠕动间置结肠 ,行结肠食管颈部吻合 2 0例 ,结肠咽腔吻合 8例。手术时间为伤后 3周～ 1年 ,其中 10例在伤后3～ 4周内手术。　结果　无手术死亡。术后颈部吻合口瘘 1例、吻合口狭窄 1例 ,术后气管切开 1例。经治疗后进普食均顺利。随访 1～ 2 2年 ,患儿发育正常。　结论　小儿食管化学性烧伤后瘢痕狭窄应积极采取胸骨后横结肠代食管 ,行食管结肠颈部吻合或结肠咽腔吻合 Objective To summarize the experience of esophageal reconstructive surgery in the treatment of scar in children with chemical burn and to discuss the prevention of common complications in this therapy. Methods The group of 28 cases were used to retain the ascending branch of the transverse artery and posterior transosternal stenosis intercostal colon intercostal line colon esophageal anastomosis 20 cases of colonic pharyngeal anastomosis in 8 cases. The operation time was 3 weeks to 1 year after injury, of which 10 cases were operated within 3 to 4 weeks after injury. The result was no operative death. One case had anastomotic fistula after neck anastomosis, one case had anastomotic stenosis and one case had tracheotomy. After treatment into the general food are smooth. Follow-up 1-22 years, children with normal development. Conclusions The stenosis of pediatric esophageal scald after burn should be taken actively on the trans-sternum transverse colon on behalf of the esophagus, esophageal colon anastomosis or colonic pharyngeal anastomosis
