Uniportal thoracoscopic apical (S1) segmentectomy of the right upper lobe via an anterior approach.

An apical (S1) segmentectomy of the right upper lobe is considered one of the most challenging procedures among the uncommon pulmonary segmentectomies. However, we consider that the uniportal thoracoscopic approach, for which the single port access is located at the 4th intercostal space of the anterior axillary line, makes this challenging operation easier because we can recognize any intrathoracic vessels and bronchi that should be divided just under the incision. Moreover, it is easy to insert a stapler to divide an intersegmental plane between S1 and the other segments because of the good surgical view provided by this approach. In this video tutorial, we describe the successful results of a patient undergoing uniportal thoracoscopic S1 segmentectomy of the right lower lobe and explain the nuances of performing it.
