Segmentectomy (the S6 + S* segment) for lung cancer with incomplete lobulation. (a) High-resolution CT and (b) three-dimensional CT images showing a pulmonary nodule in the right S6 + S* segment. The yellow box indicates the area to be resected. (c) The interlobar lung parenchyma with incomplete lobulation between the right upper and lower lobes (white dotted line) is dissected using the microwave surgical instrument toward the second carina. (d) The S6 + S* segment including the tumor emerges sufficiently from the pulmonary hilum and is subsequently sectioned off between the intersegmental plane (white dotted line) by an ASI. S6, superior segment; S*, subsuperior segment; CT, computed tomography
