Uniportal video-assisted thoracoscopic resection of anterior segment of the left upper lobe.

Anatomical segment resections are often technically more demanding than lobectomies. Anterior segment of the left upper lobe (S3) is usually removed within the standard resection of the upper three segments.    Our patient in this case was a 56-year-old with a known oropharyngeal carcinoma, otherwise amenable to curative treatment, who was admitted to our clinic with  a 1-cm nodule in the anterior segment of the left upper lobe.  Distant metastases were excluded, and a decision was made to proceed with a uniportal video-assisted thoracoscopic segmentectomy and lymphadenectomy. The procedure was successfully conducted without any adverse effects and the patient's postoperative course was uneventful.  The tumor was diagnosed as a primary solid 1-cm adenocarcinoma and the final stage was pT1aN0M0.
