Esophageal Achalasia: Symptoms, Causes, Diagnosis & Treatment

Written by Medicover Team and Medically Reviewed by Dr Raosaheb Rathod , Gastroenterologists Medical

Esophageal achalasia is a rare swallowing disorder in which the lower esophageal sphincter fails to relax properly, making it difficult for food and liquids to pass into the stomach. It is caused by damage to the nerves that control the muscles of the esophagus, leading to symptoms such as difficulty swallowing, chest pain, regurgitation of food, and weight loss. Early diagnosis and appropriate treatment can improve swallowing, relieve symptoms, and help prevent complications such as aspiration and esophageal dilation.

What are the Symptoms of Esophageal Achalasia?

The symptoms of esophageal achalasia can be varied and may develop gradually over time. Key symptoms include:

Difficulty Swallowing (Dysphagia)

Dysphagia is the most common symptom of oesophagal achalasia. Patients often report a sensation of food being stuck in the chest or throat, which can be particularly pronounced when consuming solid foods.

Regurgitation

Due to the impaired function of the oesophagus, undigested food may be regurgitated back into the mouth, leading to discomfort and potential aspiration risks.

Chest Pain

Some individuals with oesophagal achalasia experience chest pain, often described as pressure or burning in the chest. This symptom can be confused with cardiac-related conditions, necessitating a comprehensive evaluation.

Weight Loss

As eating becomes increasingly complex, individuals may experience weight loss and malnutrition, mainly if the condition is left untreated.

What are the Causes of Esophageal Achalasia?

Esophageal achalasia occurs when the nerves controlling the esophageal muscles become damaged, preventing normal relaxation of the lower esophageal sphincter. In many cases, the exact cause remains unknown.

When to See a Doctor for Esophageal Achalasia?

If you experience persistent difficulty swallowing, regurgitation of food, chest discomfort, or unexplained weight loss, consult a gastroenterologist medical or general surgeon. Early diagnosis and treatment help prevent malnutrition, aspiration, and long-term complications affecting the esophagus.

How Is Esophageal Achalasia Diagnosed?

Accurate diagnosis of esophageal achalasia is critical for effective management and treatment. The diagnostic process typically involves a combination of tests:

Esophageal Manometry

Esophageal manometry is the most definitive test for diagnosing achalasia. It measures the pressure and pattern of muscle contractions in the oesophagus, confirming the absence of peristalsis and the failure of the LES to relax.

Barium Swallow Study

A barium swallow study involves ingesting a barium solution followed by X-rays to visualize the esophagus. This test can highlight a dilated oesophagus and a narrowed LES, which are characteristics of achalasia.

Endoscopy

Endoscopy allows direct visualization of the oesophagus and LES, helping to rule out other potential causes of symptoms, such as tumours or strictures. It can also identify secondary signs of achalasia, such as esophageal dilation.

What are the Treatment Options for Esophageal Achalasia?

The treatment of esophageal achalasia focuses on alleviating symptoms and improving esophageal function. While there is no cure, several effective management strategies exist.

Pneumatic Dilation

Pneumatic dilation involves the use of a balloon to forcibly dilate the LES, allowing it to relax. This is often the first-line treatment and can be effective in reducing symptoms for a significant period, although repeat procedures may be necessary.

Surgical Myotomy

Heller myotomy is a surgical procedure in which the muscles of the LES are cut to reduce pressure and allow for better food passage. This procedure is typically performed laparoscopically and can offer long-term symptom relief.

Peroral Endoscopic Myotomy (POEM)

POEM is a newer, less invasive endoscopic procedure that achieves similar results to Heller myotomy. It involves cutting the LES muscle through the mouth, offering a promising alternative for patients who are candidates for less invasive options.

Pharmacological Management

Medications such as nitrates or calcium channel blockers can help relax the LES. However, they are generally considered less effective than procedural interventions and are often reserved for patients who cannot undergo surgery or dilation.

Botulinum Toxin Injection

Botulinum toxin can be injected into the LES to temporarily relax the muscle. This is a less invasive option often used for patients who are not candidates for surgery or dilation, although its effects are typically short-lived.

What is the Management of Esophageal Achalasia?

Effective management of oesophagal achalasia involves regular follow-up care and monitoring. Patients should work closely with their healthcare providers to adjust treatment plans as needed and address any emerging symptoms or complications. Lifestyle modifications, such as dietary changes and eating smaller, more frequent meals, can also aid in symptom management.

In conclusion, understanding esophageal achalasia, its symptoms, and available treatments is vital for those affected by this condition. Early diagnosis and intervention can significantly enhance patient outcomes and quality of life. By staying informed and proactive, patients can effectively manage their condition and lead fulfilling lives.

What is the Recovery Process for Esophageal Achalasia?

Recovery depends on treatment type and ongoing management to prevent symptom recurrence.
