Effect of minimally invasive thoracic surgical approaches on acute and chronic postoperative pain.

Acute postthoracotomy pain and chronic postthoracotomy pain are significant problems leading to increased length of hospital stay and medical costs, reduction in patient quality of life and patient productivity, and potential immunologic derangement that may compromise oncologic surgical results. Minimally invasive surgical approaches can potentially benefit the patient by reducing postoperative pain-related morbidity. Objective data supporting our inclination that these VATS approaches are superior to open thoracic surgical techniques is accumulating. Further study of the relative costs, risks, and benefits of standard postoperative analgesic management (e.g., epidural analgesia) combined with limited thoracotomy compared to VATS techniques is warranted as we try to define the most effective perioperative management of the patient requiring pulmonary resection.
