Three-port thoracoscopic middle lobectomy in a patient after left pneumonectomy.

Lung lobectomy after contralateral pneumonectomy is a challenging procedure associated with high morbidity and mortality. To date, only limited evidence has been available, and adequate indication or surgical approach remain unclear. We herein report a successful case of thoracoscopic lobectomy in a single-lung patient. A 63-year-old man, who had a history of left pneumonectomy for lung cancer, was found to have an abnormal opacity in the right middle zone at a health checkup 13 years after the previous operation. This nodule was later diagnosed as squamous cell cancer (cT2N0M0, stage IB) and surgical resection was considered. Thoracoscopic middle lobectomy with D1 lymph node dissection was performed for this patient under selective ventilation of the right upper and lower lobes. Postoperative course was uneventful and he was discharged on postoperative day 7, requiring no oxygen. The patient is doing well with no evidence of recurrence for 5 years. Given the lower invasiveness, thoracoscopic lobectomy under the selective ventilation of residual lobes could be an option after contralateral pneumonectomy in selected patients.
