The combination of duodenal atresia and esophageal atresia without tracheoesophageal fistula leads to a closed loop of bowel involving the distal esophagus, stomach, and duodenum. Prenatally, this association of anomalies is visualized as a characteristic dilated C-shaped fluid collection in the fetal abdomen. We report three cases of the association of duodenal and esophageal atresia without tracheoesophageal fistula, identified sonographically in the second trimester of pregnancy.
十二指肠闭锁与食管闭锁且无气管食管瘘的组合会导致肠道形成一个闭合环，累及食管远端、胃和十二指肠。在产前，这种异常组合表现为胎儿腹部特征性的扩张C形液体积聚。我们报告了3例十二指肠和食管闭锁且无气管食管瘘的病例，这些病例在妊娠中期通过超声检查得以确诊。
