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

Step 1: Understanding the Question:
We need to identify the condition that Ramstedt's operation is designed to treat.

Step 2: Key Formula or Approach:
Ramstedt's operation, also called pyloromyotomy, is named after the surgeon who devised it to relieve an obstruction at the outlet of the stomach in infants.

Step 3: Detailed Explanation:
Congenital atresia of the duodenum needs a completely different operation, usually a duodenoduodenostomy, to join the two blind ends of bowel together, not a pyloromyotomy.
Hallux valgus is a foot deformity, treated with a bone realigning operation of the big toe, it has nothing to do with the stomach.
Atresia of the bile duct needs biliary surgery, such as a Kasai procedure, to restore bile flow, again unrelated to the pylorus.
Congenital hypertrophic pyloric stenosis happens when the circular muscle at the pylorus, the outlet of the stomach, becomes too thick and blocks the passage of milk, causing projectile vomiting in infants a few weeks old. Ramstedt's operation splits this thickened muscle lengthwise, called a pyloromyotomy, without cutting through the inner lining, so the passage opens up while the stomach stays intact.

Step 4: Final Answer:
So Ramstedt's operation is the surgical procedure for congenital hypertrophic pyloric stenosis.
