Abstract
Background: Video-assisted thoracic surgery (VATS) is a minimally invasive procedure. This study aimed to evaluate whether the procedure is less traumatic to the ipsilateral non-diseased lobe(s) than open thoracotomy (OT) during pulmonary resection by a comparison of alveolar-capillary membrane (A/C) permeability. Methods: Wedge resections were performed in twenty-seven patients with various types of primary and secondary malignant, solitary, pulmonary nodules. Fifteen patients had OT, while 12 patients had VATS. 99 mTc-DTPA radioaerosol studies were performed on the day before surgery and on the third or fourth day postoperatively. The images of the ipsilateral non-diseased lobe(s) were compared. Results: Postoperatively, all patients had significantly increased A/C permeability at the ipsilateral non-diseased lobe(s). However, the degree of increase in the VATS group was the same as that of the OT group. Postoperative A/C permeability of the contralateral lung was not significantly different. Conclusions: Both procedures caused injury to the ipsilateral non-diseased lobe(s) in terms of A/C permeability at the same degree. Although VATS has been considered as a minimally invasive procedure, the trauma caused by VATS to the “disease-free lung” is the same as that caused by open thoracotomy.
