摘　　要：目的探讨产前超声观察肛管声像图对胎儿肛门闭锁的临床意义。方法选择2011年1月至2012年12月在日照市人民医院进行产前超声筛查并生产的孕妇13433例．年龄21～42岁．孕周20～40周：胎儿13600例。对其胎儿月肛门进行超声检查．观察胎儿肛管解剖结构多切面超声影像．评价胎儿肌管缺失的方法对筛查胎儿肛门闭锁的准确度。结果胎儿肛管声像图显示率99.2％（13493／13600）。其中孕20～27＋6周胎儿10600例。除2例肛门闭锁胎儿外．其余胎儿肛管声像图显示率为99．9％（10598／10600）．首次检查胎儿肛管声像图显示率为99．6％（10556／10600），且每例耗时〈2min，、孕28～40剧胎儿3000例．肛管声像图显示率96．5％（2895／3000）。2例胎儿肛门超声检查显示肛管声像图缺失者．引产后尸检证实为胎儿肛门闭锁．超声显示肛管声像图存在的13493例胎儿产后均排除肛门闭锁畸形。结论产前超声评价胎儿肛管有无缺失的方法简便可靠．可以提高胎儿肛门闭锁的检出率和准确度。Objective To investigate the clinical value of ultrasound observation of anal canal in the diagnosis of tetal anal atresia. Methods A total of 13 433 pregnant women performed prenatal ultrasound screening and gave birth to the chlhh＇eu from January 2011 to December 2012 were enrolled, which were aged 21 - 42 years old, gestational age 20 - 40 weeks, and fetuses were 13 600 cases. The anuses of fetal were performed by ultrasound, multi-section uhrasound imagings of fetal anal canal were observed, and the accuracy of screening fetal anal atresia of fetal loss anal was evaluated. Results The display rate of fetal anal canal sonogram in 13 600 cases was 99.2 %（13 493/13 600）, and display rate in 10 600 cases of 20 - 27＋6 weeks gestational age group was 99.9 %（10 598/10 600） except 2 cases of fetal anal atresia. The first time check was 99.6 %（10 556/10 600） with each case consuming less than 2 minutes. The display rate of fetal anal canal was 96.5 %（2 895/3 000） for 28 - 40 weeks gcstatinnal age group. Two fetuses showed fetal anal canal absence were confirmed anal atresia by autopsy after induction of labor. The 13 493 cases with presence of fetal anal canal were excluded anal atresia malformations by examination after delivery. Conclusion h is demonstrated that prenatal ultrasound can evaluate the existence of fetal anal canal, which is simple and reliable, and it can improve the detection rate and accuracy of fetal anal atresia.
