摘　　要：目的分析胎儿环状胰腺(AP)产前超声表现,探讨鸟嘴征对胎儿AP的诊断价值。资料与方法回顾性分析2019年9月—2021年12月山东省妇幼保健院经产前超声诊断结合出生后手术确诊的13例胎儿AP的超声图像及临床资料,观察梗阻处十二指肠的狭窄程度,特别是肠管内壁所成夹角能否识别胎儿AP,总结并分析其超声特征。结果13例胎儿AP的产前超声图像均出现双泡征,胰腺形态失常呈钳夹征3例,十二指肠扩张末端呈鸟嘴征7例。13例患儿出生后均行手术治疗,其中2例合并十二指肠闭锁,1例合并不典型肠旋转不良,术后患儿均预后良好。结论通过观察十二指肠扩张末端及其与胰头的关系,产前超声联合鸟嘴征及双泡征可提高胎儿AP的诊断率,对产前诊断胎儿AP具有重要价值。Purpose To explore the diagnostic value of beak sign in fetal annular pancreas by analyzing the ultrasonographic features of fetal annular pancreas.Materials and Methods The ultrasound images and clinical data of 13 cases of fetal annular pancreas diagnosed by prenatal ultrasound in Shandong Provincial Maternal and Child Health Hospital from September 2019 to December 2021 and confirmed by surgery after birth were retrospectively analyzed.The degree of duodenal stenosis at the obstruction site was observed,especially whether the angle formed by the intestinal wall could identify the fetal annular pancreas,and the ultrasonic characteristics were summarized and analyzed.Results A total of 13 fetuses with annular pancreas showed double bubble sign,3 cases showed clamp sign,and 7 cases showed beak sign at the end of duodenal dilatation.All the 13 cases underwent surgical treatment after birth,including 2 cases with duodenal atresia and 1 case with atypical intestinal malrotation.All the children had good prognosis after operation.Conclusion By observing the dilated end of duodenum and the relationship with pancreatic head,prenatal ultrasound combined with beak sign and double bubble sign could improve the diagnostic accuracy of fetal annular pancreas,which has significant value in prenatal diagnosis of fetal annular pancreas.
