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 symptoms that lead to a contrast study, including diarrhea, constipation, anorexia, irritability, apnea, lethargy, faltering growth, blood in stool, and fever.[25][26] Patients with malrotation remain at risk for volvulus and should be identified whenever possible to allow for proper therapy; thus, infants with persistent and unexplained demonstration of any of the aforementioned symptoms warrant prompt referral or investigation in consideration of upper gastrointestinal contrast study.[11]
