目的 探讨儿童厌食与胃排空的关系及促胃动力药对胃排空的影响。方法 对６０ 例厌食儿童及２０例正常儿童的胃蠕动排空进行 Ｂ 超动态观察并对比；对功能性厌食儿童予西沙必利治疗并进行疗效观察。结果 厌食儿童胃排空１／２ 时间，与正常儿童相比有显著性差异（ ｔ ＝ ４４８ ， Ｐ ＜ ００１） ；经西沙必利治疗的功能性厌食儿童胃排空时间缩短。结论 部分厌食儿童存在胃排空异常， Ｂ 超可为其诊断治疗提供可靠信息；西沙必利可缩短胃排空时间，改善厌食症状。
Objective To investigate the relationship between anorexia and gastric emptying in children and the effect of gastric motility agents on gastric emptying. Methods Sixty cases of anorexia children and 20 normal children underwent peristalsis of gastric motility were observed and compared by B-mode ultrasonography. Functional anorexia children were treated with cisapride and the curative effect was observed. Results In anaerobic children, the gastric emptying time was 1/2, which was significantly different from that in normal children (t = 448, P <001). The gastric emptying time in functional anorexic children treated with cisapride shortened. Conclusion Some anorexia children have abnormal gastric emptying, B-ultrasound can provide reliable information for its diagnosis and treatment. Cisapride can shorten the time of gastric emptying and improve the symptoms of anorexia.
