Comparison of Postoperative Pain and Pulmonary Function Between Uniportal and Multiportal Video- Assisted Thoracoscopic Surgery: A Review

Video-assisted thoracoscopic surgery (VATS) offers a minimally invasive technique for lung resection. Single- and multiple-port approaches are both widely used, with advantages and disadvantages. This study compares them regarding postoperative pain and pulmonary function. For each surgery group, visual analogue scale pain scores and forced expiratory volume in one second, forced vital capacity, total lung capacity, residual volume, and diffusion capacity of the lung for carbon monoxide values are obtained before surgery, on postoperative day 1, and 2 months after surgery.The uniportal approach is an alternative and less invasive modality for resection of pulmonary disease through the thoracic cavity. However, five- portal access was performed for multiportal VATS rather than the usual two- port or three-port VATS. Postoperative pain and pulmonary function are not significantly different between uniportal and five-portal VATS. In the uniportal-VATS group, 214 patients underwent successful resection of pulmonary disease via the single-utility port technique. The preoperative forced expiratory volume in 1 second, forced vital capacity, total lung capacity, residual volume, and diffusion capacity of the lung for carbon monoxide values are not significantly different from those of the 213 patients in the multiportal-VATS group.
