The standard operative approach to pulmonary lesions has been via postero-lateral thoracotomy
and direct vision. This technique has some advantages but its morbidity is significant. Some
surgeons advocate a resection by video-assisted thoracic surgery (VATS) to reduce the impact
on chest wall and the impairment on respiratory mechanic. However, an evidence for
superiority of the approach minimally invasive is lacking, particularly for the difficult
assessment of the change in pulmonary function. The aim of this study is to compare VATS-
over open lobectomy regarding the differences of chest wall kinematic, analyzed by
optoelectronic plethysmography (OEP).
