Patients
A registry and management protocol were started in August 2003 for patients with NSCLC who underwent surgery at Seoul National University Bundang Hospital. Pulmonary function tests (PFTs) were performed at least three times: preoperatively, and at 3 and 12 months postoperatively. From August 2003 to December 2012, 1,799 patients were enrolled in the registry. Among them, 900 patients underwent VATS lobectomy or VATS sublobar resection, which included VATS segmentectomy and VATS wedge resection.
Overall Patient Characteristics
Table 1 shows the baseline characteristics of 300 patients. The two groups did not differ significantly with respect to age, sex, smoking status, operative duration, the duration of chest tube, or hospital stay duration. However, adenocarcinoma was significantly more common in the VATS sublobar resection group. Tumor size and NSCLC stage were significantly larger and more advanced in the VATS lobectomy group. Both groups had similar baseline PFT values with respect to FVC (L), FEV1 (L), FEV1
Comment
Video-assisted thoracoscopic surgery sublobar resection was superior to VATS lobectomy for the preservation of pulmonary function. Video-assisted thoracoscopic surgery has fewer destructive properties than open thoracotomy [14]. Video-assisted thoracoscopic surgery is associated with less pain, low morbidity and mortality, and earlier recovery compared with open thoracotomy 19, 20. The National Comprehensive Cancer Network guidelines also recommend VATS for resectable NSCLC [2]. However, there

Pulmonary Function Recovery and Displacement Patterns After Anatomic Segmentectomy vs Lobectomy
2024, Annals of Thoracic SurgeryComparison of three-dimensional and two-dimensional thoracoscopic segmentectomy in lung cancer
2023, Asian Journal of SurgeryCitation Excerpt :Segmentectomy has been considered an acceptable and valuable surgical method for cT1N0M0 lung cancers smaller than 2 cm in diameter and peripheral tumors. This surgical method could offer better pulmonary function preservation than lobectomy.7-9 Thoracoscopic segmentectomy has also been demonstrated to be safe and technically feasible.10,11
Pulmonary Segmentectomy: A New Standard of Care in Patients with Non-Small Cell Cancer
2022, Journal of Cardiothoracic and Vascular AnesthesiaMinimally Invasive and Sublobar Resections for Lung Cancer
2022, Surgical Clinics of North AmericaCitation Excerpt :Tane and colleagues7 demonstrated that video-assisted thoracoscopic segmentectomy resulted in significantly preserved forced expiratory volume in 1 second (FEV1) when compared with lobectomy (91.9% postoperative/preoperative FEV1 when compared with 81.7%) in a group of matched patients. Kim and colleagues8 found that patients with NSCLC undergoing video-assisted thoracoscopic surgery (VATS) sublobar resection demonstrated greater preserved pulmonary function at 3 and 12 months postoperatively when compared with those undergoing VATS lobectomy. As more minimally invasive lung cancer resections are being performed, the benefits of preserving lung function in segmentectomy have been clarified, making anatomic segmentectomy a more attractive option in appropriate clinical scenarios.
