We investigated whether a fluid-filled duodenum is observed in normal fetuses. In part 1 of the study a view in the region of the duodenum was obtained during routine obstetric ultrasonography from 123 low-risk patients. All examinations demonstrated a collapsed duodenum. No gastrointestinal abnormalities were found in these infants. In part 2 of the study, 1163 fetuses (both high-risk and low-risk) were evaluated with real-time scanning, and duodenal fluid without a "double bubble" was seen in one fetus who had a duodenal web. We conclude that a nondistended fetal duodenum is the norm. If fetal duodenal dilation is visualized, this may allow for earlier detection of duodenal obstructions.
我们研究了正常胎儿是否会出现充满液体的十二指肠。在该研究的第1部分中，对123例低风险患者进行常规产科超声检查时，获取了十二指肠区域的图像。所有检查均显示十二指肠塌陷。这些婴儿未发现胃肠道异常。在该研究的第2部分中，对1163例胎儿（包括高风险和低风险）进行实时扫描评估，在1例患有十二指肠蹼的胎儿中发现了无“双泡征”的十二指肠液。我们得出结论，胎儿十二指肠未扩张是正常情况。如果观察到胎儿十二指肠扩张，则可能有助于更早地发现十二指肠梗阻。
