A robotic fissureless left upper lobectomy for a dense fissure.

Many articles document the efficacy of the fissureless technique, most of which focus on a right upper lobectomy. However, there are a few reports on a fissureless left upper lobectomy, especially using a robotic approach. This report presents a successful case of a robotic fissureless left upper lobectomy in a patient with a dense fissure. The total console time was 111 minutes. The postoperative course was uneventful, with the chest tube being removed on postoperative day 1. The patient was successfully discharged on postoperative day 2. The final pathology report confirmed adenocarcinoma, staged as pT1cN1M0, stage IIB. Precise preoperative evaluation using three-dimensional computed tomography broncho-angiography is essential to understand the anatomy accurately and to avoid complications in this challenging procedure.
