Abstract
OBJECTIVES: The diagnosis of small lung nodules has increased in recent years; limited resection and minimally invasive surgery are highly desirable in patients with these lesions. While wedge resection may be curative for small lung nodules, the technique is sometimes difficult to perform when the tumour nodule is near the pulmonary hilum. In such situations, either anatomical segmentectomy or subsegmentectomy can obtain an adequate surgical margin; port-access thoracoscopic surgery is the preferred type of minimally invasive surgery. Three-dimensional (3D) computed tomography (CT) simulations are reportedly useful in planning and performing thoracoscopic surgery. We use 3D CT simulation to aid thoracoscopic segmentectomy for small lung nodules and subsegmentectomy for even smaller nodules and conduct here a retrospective evaluation of the clinical results of subsegmentectomy. We present our technique for 3D CT simulation-assisted port-access thoracoscopic subsegmentectomy in the superior segment of the left lower lobe.
