The performance of ultrasound and upper gastrointestinal study in diagnosing malrotation in children, with or without volvulus.

Background: Rapid diagnosis is crucial for pediatric patients with midgut volvulus and malrotation to prevent serious complications. While the upper gastrointestinal study (UGIS) is the traditional method, the use of ultrasound (US) is gaining prominence.

Objectives: To assess the diagnostic sensitivity and specificity of US compared to UGIS for malrotation and midgut volvulus.
