Pulmonary Function Before Surgery for Pectus Excavatum and at Long-term Follow-up

Pulmonary Function Before Surgery for Pectus Excavatum and at Long-term Follow-upIndications for the surgical treatment of pectus excavatum mainly concerned cosmetic and psychological problems. However, cardiorespiratory symptoms were present in a considerable percentage of the patients preoperatively’ and were influenced positively by surgery. Whether subjective clinical improvement after surgery results from alterations in cardiopulmonary physiology has remained controversial.’ Preoperative and postoperative comparisons of lung volumes in patients yielded variable results. Some studies reported an increase in the inspiratory vital capacity (IVC) and total lung capacity (TLC), whereas more recent studies showed a significant worsening or no change after a cosmetically successful operation.
In our study, the preoperative and long-term fol low-up pulmonary function test results in a group of 152 consecutive patients who were operated on for pectus excavatum were compared retrospectively. Сanadian family pharmacy online in detail The aim was to assess whether and to what extent pulmonary function is impaired in patients with pectus excavatum, and to investigate the changes in pulmonary function caused by surgical correction. Preoperative pulmonary function in patients with pectus excavatum will be related to cardiorespiratory symptoms, physical examination findings, and chest radiographic measurements. The correlations between changes in the lung function parameters and chest diameter or subjective satisfaction are described. Between 1970 and 1987,192 patients underwent surgical repair for pectus excavatum. Only the patients who could be questioned and examined personally at the outpatients department were included in the study (N=152; 79 percent). Of these patients, 77 percent were male and 23 percent were female. The mean age at surgery was 15.3 ±5.5 years (range, 4.8 to 32.7 years). They were divided into age groups so that each group contained about the same number of patients to facilitate statistical analysis (group 1 [n=24]), 0 to 9 years; group 2 [n=24], 9 to 13 years; group 3 [n=25], 13 to 15 years; group 4 [n=19], 15 to 17 years; group 5 [n=36], 17 to 20 years; and group 6 [n=24], >20 years). The patients were followed up for a mean of 8.1 ±3.6 years (range, 2.8 to 17.7 years).
