In brief
This diagnostic study evaluates saline-aided ultrasound for detecting congenital duodenal obstruction in 95 neonates, demonstrating high accuracy in identifying duodenal web and malrotation (100%), and good performance for annular pancreas (86.3% accuracy). The technique shows promise as a non-invasive diagnostic tool for CDO.

Abstract
Purpose
The aim of the study is to assess the value of saline-aided ultrasound (US) in diagnosing congenital duodenal obstruction (CDO).
Methods
The neonates with CDO were enrolled in this study, including the neonates confirmed with annular pancreas (AP) by operation, the neonates confirmed with duodenal atresia, the neonates confirmed with duodenum web, and the neonates confirmed with malrotation. Pertinent data were recorded, including the US features, intraoperative findings, and surgical procedures. The methodology of this study is a diagnostic test study which means the US feature is the test and the intraoperative finding is the gold standard.
Results
A total of 95 neonates were enrolled, including 33 neonates with AP, 6 neonates with duodenal atresia, 29 neonates with duodenum web, and 27 neonates with malrotation. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of the hyperechogenic band for the detection of AP were 78.8% (26/33), 90.3% (56/62), 81.2% (26/32), 88.8% (56/63), and 86.3% (82/95), respectively. The sensitivity, specificity, NPV, and accuracy for the detection of duodenal atresia were 0% (0/6), 100% (89/89), 93.6% (89/95), and 93.6% (89/95), respectively. The sensitivity, specificity, PPV, NPV, and accuracy for the detection of duodenum web were 100% (29/29), 100% (66/66), 100% (29/29), 100% (66/66), and 100% (95/95), respectively. The sensitivity, specificity, PPV, NPV, and accuracy for the detection of malrotation were 100% (27/27), 100% (68/68), 100% (27/27), 100% (68/68), and 100% (95/95), respectively.
Conclusion
Saline-aided US is a feasible tool to diagnose CDO.
