Uniportal S⁶ Segmentectomy for Newly Developed Lung Cancer in the Residual Left Lower Lobe Following Left...

Uniportal video-assisted thoracic surgery (VATS) has gained global popularity as a minimally invasive surgical approach and has been increasingly adopted for various procedures in Japan. The current case report focuses on the uniportal VATS treatment of a 71-year-old female diagnosed with a lesion in the left S⁶ 2 years after undergoing left lingulectomy. The surgery was challenging due to the presence of strong adhesions, particularly in the pulmonary hilum region, thereby increasing the risk of bleeding. Uniportal VATS treatment was conducted to reduce invasiveness and facilitate early ambulation. The patient's postoperative recovery was smooth, and she remained recurrence-free up to approximately 2 years after surgery. This case highlights the challenges of reoperation after anatomical lung resection and emphasizes the importance of surgical adaptability in uniportal VATS treatment for complex cases.
