Achalasia in central Israel, 1973-83: clinical aspects

Area of Science:

• Gastroenterology
• Epidemiology
• Clinical Medicine

Background:

• Achalasia is a rare esophageal motility disorder characterized by impaired relaxation of the lower esophageal sphincter and loss of peristalsis.
• Long-term outcomes and clinical course of achalasia patients in a real-world setting are not well-documented.

Purpose of the Study:

• To evaluate the long-term clinical course and treatment outcomes in a cohort of achalasia patients.
• To assess the correlation between clinical improvement and objective diagnostic findings.

Main Methods:

• An epidemiologic study was conducted on 162 achalasia patients in central Israel with a mean follow-up of 9.9 years.
• Clinical data, including dysphagia, vomiting, aspiration, and chest pain, were compared at initial and last examinations.
• Objective assessments included X-ray, endoscopy, manometry, and esophageal retention tests.

Main Results:

• Significant clinical improvement was observed: dysphagia decreased from 100% to 62%, vomiting from 83% to 33%, aspiration from 68% to 8%, and chest pain from 36% to 33%.
• Objective measures like manometry and esophageal retention showed no significant changes over the follow-up period.
• Medical therapy, surgery, and pneumatic dilatations showed beneficial responses in 65%, 88.7%, and 82.7% of patients, respectively, with a 7.3% perforation rate for dilatations.

Conclusions:

• Achalasia patients experienced substantial long-term clinical improvement, despite minimal changes in objective diagnostic tests.
• Effective management strategies, including medical therapy, surgery, and pneumatic dilatation, contribute to improved patient outcomes.
• The study highlights the importance of symptom-based assessment in evaluating the long-term success of achalasia treatment.
