超声检测胎儿胃泡发育及其临床意义

Two-dimensional ultrasound examination for fetus stomach bubble

目的 探讨二维超声检测胎儿胃泡发育在早期筛选胎儿消化系统畸形的应用。方法 经阴道超声检测 70 例、腹部超声检测946例胎儿胃泡,随访观察其临床意义。结果 经阴道超声胎儿胃泡最早显示时间为 13 周,经腹部超声最早显示时间为15周。3例胃泡出现在胸腔内,为先天性膈疝畸形;1例小胃泡,为先天性食管闭锁;2例“双泡征”,为十二指肠闭锁。7例无胃泡,4例随访中可见胃泡正常显示;1例无胃泡并羊水过少,出生后消化系统未见异常;2 例合并羊水过多为食管闭锁;1例大胃泡,随访未见异常。结论 超声观测胎儿胃泡可以早期筛选一些胎儿消化系统畸形。

Objective To evaluate the diagnostic value of two-dimensional ultrasound examination for fetus stomach bubble and provide reference for the early diagnosis of fetus digestive system deformity. Methods Among the 1016 cases of pregnancy, 70 cases of fetus stomach bubble were diagnosed by transvaginal sonography, and 946 cases were diagnosed by routine examination; followed-up and analysed its clinical implication. Results Fetus stomach bubbles were first detected by transvaginal sonography in 13 weeks of pregnancy, and they were first detected by routine examination in 15 weeks. Three cases with thoracic stomach bubble were diagnosed congenital diaphragmatic hernias, 3 cases with small stomach bubble were esophageal atresia. Two cases with 'double bubble' were duodenal atresia. Among 7 cases shown no stomach bubble 4 cases were recurred in the following-up and 1 case with low amniotic fluid levels proved normal on postnatal growth and 2 cases with high amniotic fluid levels were esophageal atresia and 1 case with large stomach bubble proved normal in the following-up. Conclusion Two-dimensional ultrasound examination for fetus stomach bubble can be used as a method in the early diagnosis of fetus digestive system.
