En bloc resection of the left upper lobe and the anterior basal segment of the lower lobe via a uniportal thoracoscopic approach for a dense fissure.

Unidirectional dissection including a fissureless technique is a reasonable procedure for performing uniportal thoracoscopic major pulmonary resections because the angulation of the inserted surgical instruments or a thoracoscope via a single small incision is extremely limited. This type of procedure is considered useful for many types of anatomical pulmonary resections via a uniportal approach. In this video tutorial, which illustrates a more complicated case, we show en bloc resection of a left upper lobe and anterior basal segment (S8) using unidirectional dissection via a uniportal thoracoscopic approach for a patient with a dense fissure.
