Sténose hypertrophique du pylore

Hypertrophic pyloric stenosis is a frequently encountered disease in neonates. Its aetiology remains unknown, but is probably multifactorial: genetic and environmental. Diagnosis is usually based on clinical presentation, with typical (non-bilious) vomiting. Confirmation of the diagnosis relies on ultrasonography. Surgical treatment takes place after correcting the fluid deficiency and electrolyte imbalance. Recovery without sequelae is usual.
