What should initial treatment consist of?
Initial medical management is essential with re-hydration and correction of electrolyte imbalances. This should be completed prior to surgical intervention.
What is the definitive treatment once the infant has been stabilised medically?
Treatment is surgical with a pyloromyotomy in which the pyloric muscle is divided down to the submucosa.
In a normal situation, the pyloric muscle thickness (diameter of a single muscular wall on a transverse image) should normally be less than 3 mm (most accurate) and the length (longitudinal measurement) should not exceed 15 mm.
