Peripheral pure ground-glass opacity: segmentectomy versus wedge resection
Abstract Introduction Sublobar resection has been widely accepted for treating pure ground-glass opacities (GGOs). As GGOs have good prognosis, preserving postoperative pulmonary function is the major concern in surgery. No studies have yet compared the success rates of pulmonary function reservatio...
