Esophageal strictures refractory to conservative treatment (balloon dilation, bouginage) are difficult to manage. Recently, some investigators reported great success using endoscopy-guided topical application of mitomycin-C to prevent scar formation and restenosis in children with benign esophageal strictures unresponsive to balloon dilation. Herein, the authors report a fluoroscopic approach for topical application of mitomycin-C in a case of refractory esophageal stricture after surgical repair in a child with congenital esophageal atresia. This technique is a feasible alternative to endoscopic techniques.
经保守治疗（球囊扩张、探条扩张）无效的食管狭窄较难处理。最近，一些研究者报道，在对球囊扩张无效的良性食管狭窄患儿，行内镜下丝裂霉素 C 局部应用，预防瘢痕形成和再狭窄，取得了很好的效果。在此，作者报道了一种在先天性食管闭锁患儿术后难治性食管狭窄中，经 X 线透视下应用丝裂霉素 C 的方法。该技术是内镜技术的一种可行替代方法。
