Epidemiological study of achalasia in children

Area of Science:

• Pediatric Gastroenterology
• Epidemiology of Esophageal Diseases

Background:

• Achalasia is a rare esophageal motility disorder affecting children.
• Understanding the geographical distribution and incidence of pediatric achalasia is crucial for public health.
• Previous studies suggested regional variations, but data in children from Britain and Ireland were limited.

Purpose of the Study:

• To determine the incidence of achalasia in children under 15 years in Britain and Ireland.
• To investigate potential regional variations in achalasia incidence among pediatric populations.
• To explore the age at diagnosis and its relation to incidence patterns.

Main Methods:

• Retrospective analysis of 129 pediatric achalasia cases diagnosed between 1976 and 1985.
• Data collected from 175 surgeons specializing in pediatrics or esophageal diseases.
• Calculation of incidence rates per 10(5) population per year for different regions (Eire, England & Wales, Scotland, Northern Ireland).

Main Results:

• The overall incidence in Eire (0.31/10(5)/year) was significantly higher than in England and Wales (0.1/10(5)/year), Scotland (0.06/10(5)/year), and Northern Ireland (0.02/10(5)/year).
• Achalasia incidence appeared to increase with age, but diagnosis did not seem significantly delayed until early adulthood.
• Southern Irish children exhibited a greater risk of achalasia compared to other children in the British Isles.

Conclusions:

• Significant regional disparities in pediatric achalasia incidence exist within Britain and Ireland.
• Southern Ireland presents a higher risk for childhood achalasia, a pattern also observed in adult populations.
• The findings underscore the need for further research into the etiological factors contributing to these geographical variations.
