新生儿胃食管返流的影像诊断

Diagnosis of neonatal gastroesophageal reflux with radiography

目的评价新生儿胃食管返流造影的影像诊断价值。方法 82例新生儿,给予口服稀钡或水溶性碘剂在仰卧位检查,造影过程中均采取放射防护措施,并使患儿保持安静,不用腹部加压。结果造影剂吞服时食管往往有扩张,食管内造影剂排尽后发现造影剂由胃向食管返流(5 min内3次以上),并见食管胃角变钝,食管前庭部增宽。结论在良好的防护下行上消化道造影检查安全、有效,是诊断新生儿胃食管返流的重要方法。

Objective To evaluate the significance of radiography in diagnosis of neonatal gastroesophageal reflux.Methods Dilute barium or water-soluble iodine was given orally in 82 neonates with gastroesophageal reflux in the supine position.All newborns were protected well for radiation and kept quiet without abdomal compressioin during upper gastroenterography process.Results When the contrast medium was swallowed down,esophagus often dilatated.The contrast medium was found to reflux from the stomach to the esophagus （more than 3 times within 5 minutes） soon after the contrast medium entered the stomach.The oesophagogastric angle was found to be blunt and esophageal vestibular portion was widened.Conclusion Under a sufficient protection,upper gastrointestinal examination is a simple,safe and effective method in diagnosis of neonatal gastroesophageal reflux.
