目的 分析小儿腐蚀性食管炎X线表现特点 ,探讨其食管损伤程度与腐蚀剂关系。方法 16例小儿腐蚀性食管炎 ,其中男 14例 ,女 2例 ,年龄 1～ 11岁 ,平均 3 4岁。依据其吞服药物性质 ,剂量与X线表现 ,对其发病部位 ,损伤程度逐一进行对比研究。结果 16例食管狭窄范围平均为10 7cm ,占食管平均总长度的 6 3 4 %,狭窄部位直径 0 1～ 1 2cm。病变累及中段或中下段者 13例 ,占 81 3%。碱性腐蚀剂与酸性腐蚀剂所致食管平均狭窄长度占食管平均总长度的百分比分别为70 5 %和 42 0 %,两者间有显著性差异 (t=2 35 9,P <0 0 5 )。结论 小儿腐蚀性食管炎的狭窄程度与腐蚀剂的性质、浓度及吞服剂量呈正相关 ,发病部位以中段及中下段多见 ,强碱腐蚀剂所致食管损伤范围较酸性腐蚀剂更广泛。
Objective To analyze the characteristics of X-ray findings of corrosive esophagitis in children and explore the relationship between esophageal damage and etchant. Methods 16 cases of children with corrosive esophagitis, including 14 males and 2 females, aged 1 to 11 years old, with an average of 34 years old. According to its swallowed drug properties, dose and X-ray performance, the incidence of the site, the degree of injury one by one comparative study. Results The average esophageal stenosis range was 10 7 cm in 16 cases, accounting for 63.4% of the total esophageal total length and the diameter of the stenosis ranged from 0 1 to 1 2 cm. Lesions involving the middle or lower middle 13 cases, accounting for 81 3%. The percentages of average esophageal stenosis caused by alkaline etchant and acid etchant were 70 5% and 42 0%, respectively, with a significant difference (t = 2 359, P 0 05). Conclusions The degree of stenosis of corrosive esophagitis in children is positively correlated with the nature and concentration of etchant and dose of swallowing. The incidence is more common in the middle, middle and lower parts of the body. Esophageal injury caused by alkali caustic is more extensive than that of acid etchant.
