Abdominal pain – Gastric outlet stenosis

The hypertrophic pyloric muscle can be visualized by an ultrasound examination. In clinically unclear cases, an X-ray diagnosis is useful. A characteristic abnormal feature is the presence of a large gastric bubble in the abdominal overview image. If necessary, the use of computerized tomography or magnetic resonance imaging should also be considered in order to verify the diagnosis or for the purpose of differential diagnosis.
