Abstract:
PURPOSE:We attempted to identify the factors related to an early restoration of the exercise capacity after lung resection. METHODS:Major lung resection was performed in 164 patients. Exercise testing and spirometry were performed before surgery, and 2 weeks and 1 month afterward. During exercise, the maximum oxygen uptake per minute per m(2) of body surface area (VO(2)max/m(2)) was measured. The percent change of VO(2)max/m(2) at 2 weeks and 1 month after surgery was calculated by setting the preoperative VO(2)max/m(2) value as 100%. Patients were then assigned to the early restoration group or late restoration group according to their VO(2)max/m(2) measured 2 weeks after surgery. Preoperative cardiopulmonary function, as well as various preoperative and intraoperative factors were compared between the two groups. RESULTS:At 2 weeks after surgery, the mean VO(2)max/m(2) was 80.9% compared with that before surgery, and was 88.1% at 1 month. A multivariate analysis showed that the surgical method used (thoracotomy and mediastinal lymph node dissection) had a significant effect on the postoperative restoration of the VO(2)max/m(2). CONCLUSION:An early restoration of exercise capacity after lung resection is possible in patients without mediastinal lymph node dissection and in those who have a small thoracotomy wound.
