Uniportal Thoracoscopic Bisegmentectomy of Medial and Posterior Basal Segment (S7+S10)

When a tumor is located in the medial (S7) or posterior (S10) basal segment, it is sometimes necessary to perform a bisegmentectomy of S7 and S10 (S7+S10) to achieve a sufficient surgical margin. In this report, we present surgical techniques for uniportal thoracoscopic S7+S10 bisegmentectomy. The surgical technique consists of anterior and posterior procedures to dissect the basal pulmonary vein. This approach allows en bloc resection of S7+S10 and en bloc preservation of the remaining lobe.
