Chest
Clinical Investigations: SurgeryRecovery and Limitation of Exercise Capacity After Lung Resection for Lung Cancer
Section snippets
MATERIALS AND METHODS
From Januay 1991 to July 1995, 115 consecutive patients with lung cancer who were considered to be candidates for lobectomy or pneumonectomy were included in the preoperative evaluation, which consisted of pulmonary function and exercise tests. After discharge from the hospital, all 115 patients who had undergone pulmonary resection were enrolled in the repeat studies. No specific postoperative rehabilitation program was provided and informed consent was obtained from all patients. Thirty-three
RESULTS
Eighty-two patients were re-evaluated at 3 months and after more than 6 months postoperatively. All 82 patients were Japanese. Two patients were receiving medications for chronic bronchitis and six for hypertension prior to surgery. Twenty patients underwent pneumonectomies and 62 underwent lobectomies. Table 1 shows preoperative comparative data on patients in both groups. The average age, sex distributions, height, weight, and spirometric pulmonary function (VC and FEV1) were comparable in
DISCUSSION
Preoperative predictability of the reductions in pulmonary function and exercise capacity after lung resection is important. However, the changes in exercise capacity do not necessarily correlate with changes in pulmonary function.4 Previous studies have reported the loss of lung function after resection.7, 8, 9, 10, 11 The postoperative pulmonary function data (FEV1 and VC) in our series are in accordance with those of Ali et al,10 who showed that after lobectomy, there was a disproportionate
