Achalasia in Geriatric Patients: A Comprehensive Overview

Achalasia is an uncommon primary esophageal motility disorder characterized by impaired relaxation of the lower esophageal sphincter and esophageal body peristalsis, with a rising prevalence among the elderly due to global population aging. This review summarizes the current evidence on the clinical presentation, diagnostic algorithm, and management of achalasia in geriatric patients.

A literature search was conducted focusing on age-related differences in symptoms, endoscopic and functional testing, and outcomes of available therapeutic modalities.

Clinical presentation of achalasia differs among younger and geriatric patients, with the latter presenting less pronounced symptoms. Geriatric patients experience a higher risk of malnutrition and aspiration and exhibit more often advanced disease stages, including sigmoid esophagus. High-resolution manometry represents the gold standard for diagnosis, and upper gastrointestinal endoscopy should precede it in order to exclude causes of mechanical obstruction. The treatment remains non-causative and encompasses botulinum toxin injection, pneumatic dilation, peroral endoscopic myotomy, and laparoscopic Heller's myotomy with fundoplication.

Considering the evolving potential of minimally invasive techniques, advanced age should not be regarded as a contraindication for the definitive treatment of achalasia, and evidence-based, age-specific recommendations should be developed for optimizing clinical outcomes.
