Stapler-Based Thoracoscopic Basilar Segmentectomy.

Thoracoscopic S9-10 segmentectomy is more difficult than other segmentectomies because of the complexity of the peripheral pulmonary anatomies and the difficulty of dividing the intersegmental plane. In S9-10 segmentectomy, the intersegmental plane between segments S6 and S8 near the major fissure impedes division of the plane between segments S6 and S9-10, or S8 and S9-10. Dividing the intersegmental plane between segments S6 and S8 with stapling is difficult, because peripheral pulmonary anatomies are not exposed clearly. Herein, we describe the technique of stapler-based thoracoscopic S9-10 segmentectomy under indocyanine green fluorescence navigation.
