The purpose of this study was to determine the antenatal sonographic features of ileal atresia.
We identified neonates with surgically-confirmed ileal atresia who had antenatal sonography performed in our institution between 1 January 1999 and 30 June 2009. The antenatal sonography images and reports were reviewed.
Sixteen neonates had surgically-confirmed ileal atresia in our institution in 11 years. Seven fetuses (43.7%) did not have any intestinal abnormalities detected antenatally on ultrasonography. Nine fetuses (56.3%) had various sonographic features of ileal atresia, including multiple dilated bowel loops, ascites, cysts, and polyhydramnios with or without associated anomalies. Six of nine fetuses had multiple dilated bowel loops and two fetuses had ascites. One fetus had a large, cystic, mixed, echogenic dilatation of bowel. Polyhydramnios was present in three fetuses. Heart anomalies, kidney anomalies, or hydrops were present in four fetuses. Eight of 16 fetuses (50%) had other intestinal problems, including intussusceptions in one fetus, small bowel malrotation, meconium pseudocyst volvulus, meconium peritonitis, and a congenital band.
The prenatal sonographic features of ileal atresia are not simple. Various sonographic findings are shown and ileal atresia was detected in about 60% of cases.
本研究旨在确定回肠闭锁的产前超声特征。
我们确定了1999年1月1日至2009年6月30日期间在我院接受产前超声检查且手术确诊为回肠闭锁的新生儿。回顾产前超声图像和报告。
11年间我院有16例新生儿经手术确诊为回肠闭锁。7例胎儿（43.7%）产前超声检查未发现任何肠道异常。9例胎儿（56.3%）具有回肠闭锁的各种超声特征，包括多个扩张的肠袢、腹水、囊肿以及羊水过多，伴或不伴有相关畸形。9例胎儿中有6例有多个扩张的肠袢，2例胎儿有腹水。1例胎儿肠道有巨大的、囊性的、混合性回声增强的扩张。3例胎儿有羊水过多。4例胎儿有心脏畸形、肾脏畸形或水肿。16例胎儿中有8例（50%）有其他肠道问题，包括1例胎儿肠套叠、小肠旋转不良、胎粪假性囊肿扭转、胎粪性腹膜炎和一条先天性束带。
回肠闭锁的产前超声特征并不单一。出现了各种超声表现，约60%的病例可检测到回肠闭锁。
