Abstract 【Objective】 To summarize the clinical data of prenatal ultrasound diagnosis of small intestinal atresia (SBA) or small intestinal stenosis (SBS), so as to provide reference for prenatal diagnosis of fetal congenital SBA.【Methods】 A retrospective analysis of 208 cases of prenatal color Doppler ultrasound screening in our hospital from January 2013 to December 2017 was conducted. Fetal intestinal dilatation was found and autopsy was performed after operation or induction of labor. The clinical data of fetuses confirmed as SBA or SBS were analyzed statistically.【Results】 Among 208 fetuses with dilated bowel, 58 were confirmed as SBA or SBS by autopsy after operation or induction of labor. Among them, 18 cases (31.03%) were located in duodenum, 15 cases (25.9%) in jejunum and 25 cases (43.1%) in ileum. Among the 58 cases, 13 cases were complicated with other malformations and 4 cases (22.22%) were complicated with trisomy 21 syndrome. The induced labor rate of duodenal atresia or stenosis was 33.33%, the postpartum operation rate was 66.67%, and the cure rate was 91.67%; the induced labor rate of jejunal atresia was 46.67%, the postpartum operation rate was 53.33%, and the cure rate was 87.5%; the induced labor rate of ileal atresia was 48%, the postpartum operation rate was 52%, and the cure rate was 76.92%. There was no significant difference in the cure rate among the groups (P>0.05).【Conclusion】 Prenatal ultrasound plays an important role in screening congenital SBA or SBS. Because of its good surgical effect and high cure rate, prenatal diagnosis can reduce unnecessary induction of labor.
