高频超声诊断新生儿环状胰腺的价值

摘要

Objective To evaluate the clinical significance of high frequency ultrasonography in the diagnosis of annular pancreas in neonates.Methods Ultrasound results,clinical data,operation results and complicating deformity of 19 neonates were reviewed retrospectively.The digestive tracts of 19 neonates,including stomach,duodenum,jejunoileum and colon,were examined with 8-12 MHz linear transducer before surgery.Results Of 19 neonates with annular pancreas,17 cases were diagnosed with ultrasound,the diagnostic rate was 89％.The pancreas tissue encircling the descending duodenum was directly displayed as a direct sign of ultrasonography and the expansion of the proximal end of the duodenum was presented as an indirect sign of ultrasonography in 17 neonates.There were 3 neonates with annular pancreas complicating intestine malrotation and 2 neonates with annular pancreas complicating duodenal membraneous stenosis.One neonate was misdiagnosised and the other was missed.Conclusions High frequency ultrasonography plays an important role in diagnosing annular pancreas and other digestive deformity in neonates.It can be used as the first choice for the neonatal annular pancreas.%目的 探讨高频超声在新生儿环状胰腺诊断中的价值.方法 回顾性分析19例新生儿环状胰腺的超声检查结果、临床资料、术后病理情况及并发畸形.19例患儿均在术前应用高频超声,自贲门开始,沿胃体、幽门、十二指肠球部、降部、水平部升部至十二指肠空肠交界、空回肠、大肠依次扫查.结果 19例经手术证实的环状胰腺病例中,高频超声诊断正确17例,诊断率为89％.17例超声直接征象为十二指肠降部周围环绕着胰腺组织,间接征象为被包绕十二指肠近端扩张.其中3例合并肠旋转不良,2例合并十二指肠膜状狭窄,1例超声误诊,1例漏诊.结论 高频超声在新生儿环状胰腺的诊断以及合并其他畸形的诊断中具有重要价值,可作为首选检查方法.
