The Nuss procedure for pectus excavatum initially depresses pulmonary function, but forced expiratory volume in 1s (FEV1) slightly improves at two years post-surgery. Further long-term studies are needed to confirm full recovery of lung function.
Area of Science:
- Pediatric Surgery
- Thoracic Surgery
- Pulmonary Medicine
Background:
- Pectus excavatum is a common congenital chest wall deformity in children.
- It often leads to impaired pulmonary function.
- The effectiveness of the Nuss procedure in restoring lung function remains debated.
Purpose of the Study:
- To evaluate changes in pulmonary function after the Nuss procedure.
- To analyze the impact of the Nuss procedure on lung function in pediatric patients.
Main Methods:
- Systematic literature search of MEDLINE, Embase, Cochrane, and PubMed.
- Included studies with pre- and post-operative pulmonary function tests (PFTs).
- Analyzed forced expiratory volume in 1s (FEV1) and forced vital capacity (FVC); subgroup analyses by time and age.
Main Results:
- 13 studies with 465 participants were analyzed.
- Post-surgery FEV1 showed a slight increase (SMD 0.17, p=0.04), while FVC showed a non-significant decrease (SMD -0.18, p=0.14).
- A temporal relationship was observed, with FEV1 higher more than 2 years post-surgery (SMD 0.26, p=0.012).
Conclusions:
- The Nuss procedure initially depresses pulmonary function.
- FEV1 shows a slight improvement at two years post-surgery compared to baseline.
- Longer follow-up studies are necessary to determine if pulmonary function normalizes.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
