Two-stage S7 sleeve resection of the right lower lobe and S1+2 and S3 segmentectomy of the left upper lobe: a case report.

Synchronous multiple nodules in the lungs, such as peripheral ground-glass opacities (GGOs) and solid small nodules, are common, but only lesions suspected of being malignant should be surgically removed. The surgical strategy is anatomical sub-lobectomy in early stage of non-small cell lung cancer synchronously or asynchronously to decrease the impact of lung resection on the lung function. Here, we report a case of a 56-year-old man, who was a pack-a-day smoker, with endobronchial hamartomas the medial basal bronchus (B7). The patient underwent sleeve resection of the medial basal segment in the right lower lobe, followed by S1+2 and S3 segmentectomy because of early-stage lung adenocarcinoma (T1a), which presented as mixed GGOs located in the left upper lobe. The performance of S7 sleeve segmentectomy of the RLL is very rare. The main concern is stenosis of the anastomosis and the major technical striking point is the caliber discrepancy between proximal and distal bronchi. In our experiences, we used high-tech methods as three-dimensional reconstruction to provide a basis for our surgical planning and proper patient selection and a series of preventing measures taken for anastomotic stenosis, successfully avoided complications. This case provides a new strategy for the treatment of patient with multiple early-stage lung cancer and benign endobronchial tumors, simultaneously.
