Congenital Hypertrophic Pyloric Stenosis | Ultrasound Diagnosis, Symptoms & Management in Neonates

Congenital Hypertrophic Pyloric Stenosis (CHPS) is a common cause of gastric outlet obstruction in neonates. It results from progressive thickening of the pyloric muscle, producing a narrowed and elongated pyloric canal. Clinically, affected infants present with non-bilious projectile vomiting, visible gastric peristalsis, dehydration, and failure to thrive. On palpation, an “olive-shaped” mass may be felt in the epigastrium. Ultrasound is the investigation of choice, revealing diagnostic features such as pyloric muscle thickness greater than 3–4 mm, channel length exceeding 15–18 mm, and the classical “target” or “donut” sign in transverse view. Color Doppler may show poor passage of gastric contents and vascularity within the hypertrophied muscle. Prognosis is excellent with early recognition and treatment. After correction of fluid and electrolyte imbalance, surgical Ramstedt pyloromyotomy provides definitive cure with rapid recovery.
