Feasibility of Uniportal Thoracoscopic Right Medial-Basal (S7) Segmentectomy

Thoracoscopic right medial-basal (S7) segmentectomy is technically challenging due to its small size, depth, and anatomical complexity, especially through a uniportal thoracoscopic approach because of the limited angulation of the surgical instruments or staplers used. Herein, we report a successful case of right S7 segmentectomy through a uniportal approach with sufficient surgical margin. Key aspects are to mobilize the lung by dissecting the pulmonary ligament, dividing a fissure, and exposing the pulmonary vein branches to the periphery, which allowed us to perform smooth and safe stapling through the single skin incision.
