目的 通过核素扫描及钡餐透视检查,观察小儿胃食管返流的影像学特点及诊断的客观指标。方法 对胃食管返流(GER)、食管裂孔疝、先天性肥厚性幽门狭窄患儿及同龄对照组进行影像学检查,并计算胃潴留率、返流指数等项指标。结果 钡餐透视检查:食管裂孔疝患儿一部分胃位于膈上;GER越重,则His角越大、腹腔食管长度越短;术后GER患儿症状消失、食管长度延长。核素扫描检查:食管旁疝胃呈亚铃型、病例组患儿的胃潴留率及返流指数明显增高,术后胃潴留率、返流指数恢复正常。结论 影像学检查可以观察到GER的影像特点及确定诊断的客观指标。
Objective To observe the imaging characteristics of children with gastroesophageal reflux and objective indicators of diagnosis by radionuclide scanning and barium meal fluoroscopy. Methods Gastroesophageal reflux (GER), hiatal hernia, congenital hypertrophic pyloric stenosis and control group of the same age were studied by imaging examination, and the indexes of gastric retention and reflux index were calculated. The results of barium meal fluoroscopy: hiatal hernia in children with a part of the stomach located in the diaphragm; GER heavier, the larger the His angle, the shorter the abdominal cavity esophagus; GER children after surgery symptoms disappear esophageal length. Radionuclide scan showed that the stomach of the parahippocampal hernia was in the shape of an arboreal. The gastric retention rate and reflux index of the children in the case group were significantly increased. The rate of gastric retention and regurgitation returned to normal after operation. Conclusion Imaging findings can be observed GER image features and to determine the objective indicators of diagnosis.
