Current clinical approach to achalasia

Area of Science:

• Gastroenterology
• Esophageal Motility Disorders
• Autoimmune Diseases

Background:

• Idiopathic achalasia is a rare primary esophageal motility disorder.
• Characterized by impaired lower esophageal sphincter (LES) relaxation and absent esophageal peristalsis.
• Pathogenesis involves autoimmune destruction of inhibitory neurons in susceptible individuals, with an unidentified trigger.

Discussion:

• Diagnosis relies on clinical suspicion confirmed by esophagogastroduodenoscopy (EGD), manometry, or barium swallow.
• Diagnostic tools aid in excluding pseudoachalasia and classifying disease severity or subtype.
• High-resolution manometry (HRM) shows promise in predicting treatment response.

Key Insights:

• Achalasia leads to dysphagia, regurgitation, weight loss, and potential respiratory issues.
• Laparoscopic Heller myotomy with partial fundoplication appears more effective for long-term symptom relief than endoscopic methods.
• Treatment decisions should consider patient characteristics, disease subtype, local expertise, and patient preference.

Outlook:

• Further research into the autoimmune pathogenesis and specific triggers of achalasia is warranted.
• Advancements in diagnostic techniques like HRM may refine treatment selection and prognostication.
• Optimizing treatment strategies requires a personalized approach balancing efficacy and patient factors.
