Different extents of resection in anatomical segmentectomy for the same pulmonary lesion. An example of (A) conventional anatomical segmentectomy (the arrow indicates the tumor to be targeted); (B) extended segmentectomy; and (C) combined subsegmentectomy, for the same lesion located in left segment 8 (S8). Compared with conventional anatomical segmentectomy in which the resection may be “unbalanced,” extended segmentectomy and combined subsegmentectomy may provide better resection margins.
