Diagnostic Evaluation of X-ray and US Manifestations of Upper Digestive Tract Obstruction in Infant(A Report of 20 Cases) / 实用放射学杂志

ABSTRACT

Objective To study the evaluation between the X-ray findings and ultrasound(US) manifestations of upper digestiveobstruction in infancy.Methods X-ray and US manifestations of 20 cases of infant with upper digestive obstruction proved by operationwere analysed respectively.Results In 20 cases,12 patients had pyloric stenosis,3 duodenal stresia,3 midgut malformation,2 hiatalhernia.Pyloric stenosis was diagnosed by X-ray in 11 cases,by US in 9,misdiagnosed by US in 1 case.Duodenal stresia was observed by X-ray and US in 2 cases separately,not observed by X-ray and US in 1 case separately.Midgut malformation was demonstrated by X-ray and US in 1 case separately,not demonstrated in 2 cases separately.Hiatal hernia was found by X-ray in 2 cases,misdiagnosed by US in 2 cases.Conclusion The two methods can't substitute with each other but complement.X-ray is better than US in the diagnosis of pyloric stenosis and hiatal hernia.US is better than X-ray in the diagnosis of midgut malformation.
