Abstract
With the recent increase in small-sized lung cancers, sublobar resection and minimally invasive surgeries are
becoming preferred. In particular, the detection of ground-glass nodules (GGNs) on high-resolution computed
tomography has increased. Although lobectomy has been considered a standard procedure for treating lung
cancer, sublobar resections have been indicated for treating GGN-dominant small-sized lung cancers. Wedge
resection and segmentectomy have generally been performed as sublobar resection; however, each procedure
has some technical advantages and disadvantages. Although anatomical resection as a segmentectomy is a
complicated procedure, it has recently been increasingly performed with the accurate anatomical grasp using
three-dimensional computed tomography and the identification of the intersegmental plane. Other procedures
involving the use of newer technologies can also be performed. Individualized sublobar resection might be a
suitable procedure for small-sized lung cancer with the appropriate selection of procedures based on each tumor’s
characteristics and improving the methods to overcome some technical difficulties.
