Screening
Asymptomatic diagnosis
While the infant population is not screened for malrotation, which may be present in an asymptomatic manner, it is important to consider that malrotation without volvulus is diagnosed for a wide variety of complaints that lead to a contrast study, including diarrhoea, constipation, anorexia, irritability, apnoea, lethargy, failure to thrive, blood in stool, and fever.[11] Patients with malrotation remain at risk for volvulus and should be identified whenever possible to allow for proper therapy; thus, infants with persistent demonstration of any of the aforementioned symptoms should have a prompt upper gastrointestinal contrast study.
