- Barium swallow/upper GI series.
Can pyloric stenosis be seen on ultrasound?
In a study by Leaphart et al, ultrasonography confirmed hypertrophic pyloric stenosis when the pyloric muscle thickness (MT) was greater than 4 mm and the pyloric channel length (CL) was greater than 15 mm.
What is congenital pyloric stenosis?
Pyloric stenosis is an uncommon condition in infants that blocks food from entering the small intestine. Normally, a muscular valve (pylorus) between the stomach and small intestine holds food in the stomach until it is ready for the next stage in the digestive process.

and acts as an acoustic window. Begin by scanning transversely to locate the pylorus, which is found medial and posterior to the gallbladder . Procedure • Assess for the passage of fluids through the pyloric canal. An open canal with normal passage of gastric content excludes hypertrophic pyloric stenosis (HPS).
