To assess the diagnostic value of ultrasonography (US) for congenital small bowel atresia (SBA) in neonates and their sonographic characteristics.
A retrospective analysis was performed of 20 neonates who were confirmed with SBA by operation from March 2014 to January 2019. All the neonates have been scanned by US before surgery, and no one underwent barium enema or upper gastrointestinal imaging prior to US. Preoperation ultrasound characteristics about intestinal morphology and intestinal contents were collected, further to summarize the typical ultrasonic features of SBA.
Five cases were duodenal atresia, and 15 cases were jejuno-ileal atresia. Distended proximal intestines, liquid with tiny points in it, can be found in 20 neonates. The small intestine without any gas can be found in 20 neonates. Microcolon, no gas and other contents in it, can be found in 16 cases.
The typical ultrasonic features of SBA include dilation in proximal intestines, small intestines, and microcolon. US is a promising modality in the clinical diagnosis of SBA.
评估超声（US）在新生儿先天性小肠闭锁（SBA）中的诊断价值及其声像图特征。
对 2014 年 3 月至 2019 年 1 月间经手术证实为 SBA 的 20 例新生儿进行回顾性分析。所有新生儿均在手术前接受 US 检查，且在 US 检查前均未进行钡灌肠或上消化道影像学检查。收集术前关于肠形态和肠内容物的超声特征，进一步总结 SBA 的典型超声特征。
5 例为十二指肠闭锁，15 例为空肠回肠闭锁。20 例新生儿均可见近端肠管扩张，内有细小点状液体。20 例新生儿均未见含气的小肠。16 例可见微小结肠，无气及其他内容物。
SBA 的典型超声特征包括近端肠管、小肠和微小结肠扩张。US 是 SBA 临床诊断中一种很有前途的方法。
