Summary
Surgical correction for pectus excavatum did not improve pulmonary function and worsened restriction. Lung function declined post-surgery, particularly in patients with milder preoperative impairment.
Area of Science:
- Thoracic Surgery
- Pulmonary Medicine
- Medical Engineering
Background:
- Pectus excavatum, a chest wall deformity, can impact respiratory function.
- Surgical correction aims to improve both aesthetics and physiological function.
- Long-term effects of surgical correction on pulmonary function require further investigation.
Purpose of the Study:
- To assess pulmonary function impairment before and after surgical correction of pectus excavatum.
- To investigate changes in lung function over time following surgical intervention.
- To identify factors influencing pulmonary function changes and surgical outcomes.
Main Methods:
- Pulmonary function tests (PFTs) were conducted on 152 patients pre- and post-surgery.
- Long-term follow-up data were analyzed to track changes in lung function.
- Multivariate analysis was used to correlate PFTs with clinical and surgical parameters.
Main Results:
- Preoperative PFTs revealed restricted pulmonary function in most patients.
- Despite symptom improvement, lung function (Total Lung Capacity and Inspiratory Vital Capacity) significantly decreased post-surgery.
- The decline in lung function was more pronounced in patients with less preoperative impairment.
Conclusions:
- Surgical correction for pectus excavatum does not restore, and may worsen, pulmonary function.
- The observed decline in lung function post-surgery warrants further research into underlying mechanisms.
- Current surgical approaches may not adequately address or could negatively impact long-term respiratory health.
