Current therapies for achalasia: comparison and efficacy

Area of Science:

• Gastroenterology
• Esophageal Motility Disorders

Background:

• Achalasia is a primary esophageal motor disorder causing dysphagia, regurgitation, and chest pain.
• Current treatments aim to reduce lower esophageal sphincter (LES) pressure for improved esophageal emptying.

Purpose of the Study:

• To review current treatment strategies for achalasia.
• To compare the efficacy and outcomes of pneumatic dilation and surgical myotomy.

Main Methods:

• Review of current literature on achalasia treatments.
• Comparison of pneumatic dilation (Rigiflex balloons) and laparoscopic myotomy outcomes.
• Evaluation of the role of calcium channel blockers, nitrates, and botulinum toxin injections.

Main Results:

• Graded pneumatic dilation with Rigiflex balloons achieves up to 90% symptom improvement.
• Laparoscopic myotomy demonstrates high efficacy (94%) with reduced morbidity and hospitalization.
• Both pneumatic dilation and laparoscopic myotomy are equally efficacious treatment options for most achalasia patients.

Conclusions:

• Pneumatic dilation and laparoscopic myotomy are the primary effective treatments for achalasia.
• Botulinum toxin injection is reserved for patients unsuitable for dilation or surgery.
• Advances provide patients with effective, less invasive treatment choices for achalasia.
