Summary
Hiatus hernia can reduce lung function. This study found that larger hiatus hernias correlate with decreased regional ventilation, perfusion, and lung volume in affected individuals.
Area of Science:
- Pulmonary Medicine
- Gastroenterology
- Radiology
Background:
- Hiatus hernia is a common condition affecting the gastroesophageal junction.
- The impact of hiatus hernia size on lung function is not fully understood.
Purpose of the Study:
- To investigate the relationship between hiatus hernia size and lung function parameters.
- To assess regional ventilation, perfusion, and lung volume in patients with hiatus hernia.
Main Methods:
- Sixty-four subjects with hiatus hernia were categorized by thoracic loculus diameter.
- 133Xe-radio-spirometry was used to examine lung function in the supine position.
Main Results:
- 48 subjects demonstrated reduced regional ventilation, perfusion, or lung volume.
- A significant correlation was observed between thoracic loculus diameter and impaired lung function variables.
Conclusions:
- Hiatus hernia, particularly larger ones, can lead to significant reductions in lung function.
- Thoracic loculus diameter is a predictor of lung function impairment in hiatus hernia patients.
