Isokinetic muscle strength after thoracotomy: standard vs. muscle-sparing posterolateral thoracotomy
1Department of Thoracic Surgery, Istanbul Universty Istanbul Medical School, Istanbul, Turkey.
Background:
The aim of the study was to compare the effects of conventional posterolateral thoracotomy and muscle-sparing posterolateral thoracotomy on pulmonary and muscle strength.
Methods:
From January 2003 to December 2004, 50 randomized patients with a diagnosis of primary lung cancer underwent pulmonary resection. The patients were divided into two groups: Group I (n=25) underwent conventional posterolateral thoracotomy, while Group II (n=25) had muscle-sparing thoracotomy. The groups were compared in terms of shoulder abduction/adduction isokinetic muscle strength and respiratory muscle strength.
Results:
A comparison of maximal expiratory pressure and maximal inspiratory pressure preoperatively and postoperatively and of maximal expiratory pressure and maximal inspiratory pressure preoperatively and at 3 months postoperatively showed statistically significant differences (P<0.05).
Conclusion:
For the preservation of muscle strength, especially in patients whose jobs involved manual work, muscle-sparing posterolateral thoracotomy should be the first choice rather than conventional thoracotomy. Moreover, if necessary, the latissimus dorsi muscle can be used more extensively as a flap after muscle-sparing posterolateral thoracotomy procedures.
