The presence of dilated bowel loops antenatally suggests fetal bowel obstruction. Neonatal intestinal obstruction can have different variations in presentation depending on the level and extent of obstruction. Some of these conditions can be diagnosed antenatally. Antenatal detection of surgically correctable anomalies would ideally reduce perinatal morbidity and mortality by allowing a planned delivery with early resuscitation and prompt surgical intervention. Duodenal atresia is the most common intestinal atresia diagnosed in a fetus. Presently there are no significant abnormalities of the fetal gastrointestinal tract that benefit from fetal intervention. However a thorough understanding of the disease processes is necessary for diagnosis and treatment of intestinal obstruction. With advances in neonatal intensive care and management there has been a significant decrease in mortality rates of neonates with intestinal obstruction.
产前出现扩张的肠袢提示胎儿肠梗阻。新生儿肠梗阻根据梗阻的部位和范围不同，临床表现也有所差异。其中一些情况可在产前诊断。产前检测出可手术矫正的异常情况，理想情况下可通过计划分娩、早期复苏和及时的手术干预来降低围产期发病率和死亡率。十二指肠闭锁是胎儿中最常见的肠道闭锁类型。目前，胎儿胃肠道没有明显异常可通过胎儿干预得到改善。然而，对于肠梗阻的诊断和治疗，深入了解疾病过程是必要的。随着新生儿重症监护和管理的进步，肠梗阻新生儿的死亡率已显著下降。
