A classic physical finding in pediatric pyloric stenosis is

• A. Palpable olive-shaped mass in the epigastric region
• B. Projectile vomiting
• C. Bilious vomiting
• D. Diarrhea

Answer: (A)

A firm, olive-shaped mass in the epigastric region is the classic physical finding in pediatric pyloric stenosis. This represents the hypertrophied pylorus. It’s often best felt after feeding when the stomach is distended, and you may also notice visible peristaltic waves crossing the abdomen as the stomach tries to move contents past the narrowed outlet. While projectile vomiting is a hallmark symptom of the condition, it’s a clinical presentation rather than a physical sign. Bilious vomiting would point toward an obstruction distal to the pylorus, and diarrhea is not typical for pyloric stenosis. Ultrasound reliably confirms the diagnosis by showing thickened and elongated pyloric muscle, and treatment involves correcting dehydration and electrolytes followed by surgical pyloromyotomy.
