INTRODUCTION: Patients with pectus excavatum are currently treated with Nuss surgery, but until now the influence of this procedure on long term pulmonary function and psychological status is unknown. AIM: The aim of the study was to asses9 ventilatory and physical capacity,patients satisfaction and predisposition to develop depression after Nuss surgery. MATERIAL AND METHODS: 58 patients at least two years post bar explanation and 40 controls were enrolled into the study. The age and sex distribution of control group did not differ significantly from the study group (p=0.2). Both groups were assessed with the use of: spirometry, bodyplethysmography, six minute walking test (6MWT), Beck Depression Inventory (BDI). Operated patients filled a satisfaction questionnaire. RESULTS: The lung function measurements of operated patients were significantly lower compared to controls: FVC 93.5±13.7; 102.8±11.9 [%] (p=0.001); TLC 100±12.1; 107±9.7 [%] (p=0.005), RV/TLC 29.7±5; 24.6±5.5 [%] (p 1 /FVC: 89.3±7.3; 85.6±7 (p=0.02), FEV 1 : 97.2±17.5; 103.1±12.6 [%] (p=0.02). There were no differences in 6MWT distances: 699±76; 719±73 [m] p=0.89, exercise induced hypoxemia SpO2 min: 96.1±2.2; 98.1±9.9 [%] (p=0.29), depression BDI: 4.5±4.4; 5.5±5.7 (p=0.54) between studied groups. According to the questionnaire correction of sunken chest by Nuss procedure was found painful (72.7%), but the long term effect was found good (77.2%) and therefore 80.3% of patients would recommend this procedure. CONCLUSIONS: Patients operated in the past by Nuss procedure have significantly decreased lung function measurements, however their ability to perform effort is not decreased and they do not tend to develop depression. |
