Uniportal thoracoscopic right anterior basal (S8) segmentectomy using unidirectional dissection.

Anterior basal (S8) segmentectomy is one of the most challenging procedures among the uncommon pulmonary segmentectomies because the surgeon has to identify dominant pulmonary vein branches located deep in the lung parenchyma. Moreover, with the uniportal thoracoscopic approach, the angulation of inserted surgical instruments via a single small incision is extremely limited, which causes technical difficulties. However, adoption of a suitable procedure such as unidirectional dissection enables us to perform this type of minimally invasive surgical procedure. We describe the successful results of a patient undergoing uniportal thoracoscopic S8 segmentectomy of the right lower lobe and explain the nuances of performing it.
