Diagnosis of congenital duodenal obstruction in children with high frequency ultrasound combined with gastrointestinal filling

Objective To investigate the diagnostic value of high frequency color Doppler ultrasound combined with gastrointestinal filling in infants with duodenal obstruction. Methods One hundred infants who were suspected with duodenal obstruction underwent both gastrointestinal ultrasound and upper gastrointestinal tract, put the surgical results as the"gold standard", the values of ultrasonic and upper gastrointestinal tract in the diagnosis of pediatric congenital duodenal obstruction were compared. Results The diagnostic accuracy of ultrasound and upper gastrointestinal tract in duodenal obstruction was 100% and 94% respectively, the difference was statistically significant (P=0.041). The accuracy rate of obstruction location was 98.04% and 84.31% respectively, also was considered to denote statistical significance (P=0.023). The total diagnostic accuracy of congenital disorders caused by duodenal obstruction was 89% and 49% respectively, and P=0.001 implies statistically significant difference. Conclusions There is a high diagnostic accuracy in high frequency ultrasound combined with gastrointestinal filling in children with congenital duodenal obstruction, and the diagnosis of some diseases is better than that of the upper gastroenterography.
