Abstract:
In pulmonary segmentectomy, the dominant pulmonary arteries are traditionally divided at the fissure. However, this approach sometimes leads to inadvertent injury to the pulmonary artery and prolonged air leak when the fissure is fused. To overcome these problems, by taking advantage of the good visualization provided by robotic surgery, we have adopted the lung-inverted approach without fissure dissection for segmentectomy. We have successfully performed a robotic left S6 and S1+2c segmentectomy using the lung-inverted approach. In addition to a good postoperative course, the console time was 57 minutes, which was considered relatively short. This approach may have contributed to the short operating time because it did not require repeated rotation of the lung. A clear understanding of the anatomy was required to perform this approach properly, because each branch of the pulmonary vessels and bronchi was treated inverted at the hilum. A preoperative 3-dimensional computed tomography broncho-angiographic scan was considered useful because it allowed us to recognize the relative positions of the dominant pulmonary vessels, the bronchi and other structures that were preserved.
