摘　　要：目的分析总结胎儿下消化道梗阻的超声诊断思路。方法回顾我院产前超声检查发现的胎儿下消化道肠管扩张45例,并认识观察肠管的变化,密切追踪梗阻的发生和发展。结果胎儿下消化道梗阻重要超声表现是肠管扩张,小肠管径一般增宽8 mm以上,或结肠襻最宽超过18 mm。其中证实下消化道畸形6例(13.3%),39例(86.7%)肠管扩张为一过性地梗阻,无不良围产期结果。结论客观分析胎儿下消化道梗阻的动态变化或持久异常对临床产科具有重要的指导意义。Objective To conclude the methods of ultrasonic diagnose on the lower digestive tract obstruction （LDTO） of fetus. Methods Retrospect anternatal ultrasonic examination of 45 fetuses whose lower enterons were found expanding, observe the changes on the intestine, closely track the incidence and development of the obstruction. Results The ultrasonic manifestation of lower enteron obstruction was intestinal canal dilatation. The diameter of the intestine widened more than 8 mm. And the widest part of the colon was over 18mm. Six cases （13.3%） were with malformated lower enteron, and 39 cases （86.7%） with intestinal canal expanding were transient obstruction without bad peripartum results. Conclusions It is meaningful for clinical obstetrics to analyse the changes or permanent malformation of fetus LDTO.
