Heller's myotomy is done for which condition?
Show Hint
The operation cuts the lower oesophageal sphincter muscle.
Updated On: Jun 23, 2026
- Zenker's diverticulum
- Achalasia cardia
- Bunions
- Knee arthroscopy
Show Solution
The Correct Option is B
Solution and Explanation
Step 1: Decode the eponym. Heller's myotomy specifically targets the non-relaxing lower oesophageal sphincter, so it must belong to a disease of impaired oesophageal emptying.
Step 2: That disease is achalasia cardia, where the sphincter stays tight and the body of the oesophagus loses peristalsis. Cutting the muscle at the gastro-oesophageal junction relieves the obstruction and lets swallowed food drain into the stomach.
Step 3: The remaining options are unrelated - a pharyngeal pouch (Zenker), a great-toe deformity (bunion) and a knee scope procedure have nothing to do with this oesophageal operation. Achalasia is the correct match.\[\boxed{\text{Achalasia cardia}}\]
