Heller’s operation done for –
## **Core Concept**
Heller's operation, also known as Heller myotomy, is a surgical procedure used to treat **achalasia**, a motility disorder of the esophagus characterized by the failure of the lower esophageal sphincter (LES) to relax, leading to difficulty in swallowing.
## **Why the Correct Answer is Right**
The correct answer, **achalasia**, is the primary indication for Heller's operation. This procedure involves making a longitudinal incision in the distal esophagus, extending to the LES, to reduce its pressure and improve esophageal emptying. The operation aims to alleviate symptoms such as dysphagia (difficulty swallowing) and regurgitation of food. The **lower esophageal sphincter (LES)** plays a crucial role in this condition, as its failure to relax prevents normal passage of food into the stomach.
## **Why Each Wrong Option is Incorrect**
- **Option A:** While **diffuse esophageal spasm** is another esophageal motility disorder, Heller's operation is not primarily indicated for this condition. Treatment for diffuse esophageal spasm often involves medications to relax the esophageal muscles.
- **Option B:** **Gastroesophageal reflux disease (GERD)** is a condition where stomach acid frequently flows back into the tube connecting the mouth and stomach (esophagus). Although surgical interventions are available for GERD, Heller's operation is not the primary treatment; instead, fundoplication is often considered.
- **Option C:** This option seems to be missing but based on the context, conditions like **esophageal stricture** or other esophageal disorders are not the primary indications for Heller's operation.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that Heller's myotomy can be performed **laparoscopically** or **open** and is often considered for patients with achalasia who do not respond to or cannot undergo pneumatic dilation. A notable complication of Heller's myotomy is **gastroesophageal reflux**, which can be mitigated by performing a partial fundoplication.
