Question 2. Is Doppler ultrasound superior to upper gastrointestinal contrast study for the diagnosis of malrotation?

摘要

Three-day-old twins are reported to have persistent bilious vomiting on the postnatal ward. You suspect midgut mal-rotation and it is suggested by a colleague that a Doppler ultrasound might be a better investigation than an upper gastrointestinal (UGI) contrast study, as it does not involve radiation and is non-invasive. You are uncertain which test is best.In an infant with bilious vomiting [patient], is a Doppler ultrasound [intervention] superior to an UGI contrast study [comparison] for the diagnosis of malrotation [outcome]?
