Abstract
IntroductionSublobar 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 reservation between segmentectomy and wedge resection.MethodThe three-dimensional rebuild of computed tomography (CT) images was performed, the segmentectomy and wedge resection of the GGO in the target segment were simulated, and the area of cut surface was measured, which was important data for successful postoperative pulmonary recruitment maneuvers.ResultWith equal volumes of tissue removed, segmentectomy and wedge resection showed similar surface area loss for RS4 and RS5, followed by LS7 + 8, LS6 and LS1 + 2 segments. Compared with other segments, wedge resection performed in RS10, LS3, LS10, RS9 and RS7 may lead to a loss of lot more surface area than segmentectomy.ConclusionWedge resection is suggested for segments RS4, RS5, LS1 + 2 and LS7 + 8, whereas segmentectomy is advised for segments RS1, LS4 + 5 and RS2. Meanwhile, deep wedge resection should be avoided for segments RS8, RS7, RS10, LS3, LS10. RS9 and LS9, in order to preserve a larger lung surface area.

Summary
Sublobar resection has been widely accepted for treating pure ground-glass opacities (GGOs). Surgical excision is optional for pure GGOs up to 5 mm if they are increasing in size and for pure GGOs larger than 10 mm that remain stable but are persistent [6]. Compared with traditional lung cancer, GGOs, especially pure GGOs show relatively benign biological behavior. It is not currently clear whether lobectomy is still necessary to achieve a “radical” resection of GGOs. It is not currently clear whether lobectomy is still necessary to achieve a “radical” resection of GGOs In this respect, a series of studies comparing sublobar resection and lobectomy were published. National Comprehensive Cancer Network (NCCN) guidelines have suggested that sublobar resection could be applied for peripheral nodule ≤ 2 cm with at least one of the
