Question

Ramstedts operation is the surgical procedure for

• A. Congenital atresia of duodenum
• B. Hallux valgus
• C. Congenital hypertrophic pyloric stenosis
• D. Atresia of bile duct

Hint:

Think of the operation that splits the thickened pyloric muscle in infants with projectile vomiting.

Answer 1

The Correct Option is C

This question asks which condition Ramstedt's operation is used to treat. Let's look at each option.

1. Congenital atresia of duodenum: This blockage needs the two blind ends of bowel joined together surgically, a duodenoduodenostomy, not a pyloromyotomy.
2. Hallux valgus: A bent big toe deformity, corrected with a bone realignment operation on the foot, unrelated to the stomach or pylorus.
3. Congenital hypertrophic pyloric stenosis: The muscle ring at the stomach outlet, the pylorus, grows too thick in some infants and blocks milk from passing through, causing projectile vomiting a few weeks after birth. Ramstedt's operation, known as pyloromyotomy, cuts through this thickened muscle layer lengthwise, without opening the inner lining, so milk can pass freely again.
4. Atresia of bile duct: This needs biliary surgery such as a Kasai procedure to restore bile drainage, not a pyloromyotomy.

Only the pyloric stenosis option matches what Ramstedt's operation actually does, splitting the thickened pyloric muscle.

Let's summarize:

• Ramstedt's operation is a pyloromyotomy that splits the thickened pyloric muscle.
• The other three conditions need entirely different operations.

So Ramstedt's operation is the surgical procedure for congenital hypertrophic pyloric stenosis.
