Today, video-assisted thoracic surgery (VATS) was very popular and more and more common, which could be carried out at all levels of medical centers, most of which used multiple-ports VATS techniques.However, uniportal VATS was more difficult technique compared with multiple-ports VATS, and was not yet completely universal. Uniportal port VATS with 2 cm incision was more difficult surgery, and asked the surgeon to master more surgical techniques and good collaborations with each other, however, which not only could reduce the postoperative pain and skin numbness but supply cosmetology and psychological comfort for patients. To reduce unnecessary damage to patients, we minimized the incision to 2 cm. Therefore, we called it precise uniportal port VATS technique in our surgical center and introduced it here. screening. Chest CT imaging showed a 15 mm × 13 mm solitary ground glass opacity (GGO) with air bronchogram in the right middle lobe, and mean CT value of the GGO was 618 Hu (Figure 1). He accepted standard antiinflammatory treatment for 2 weeks, then he was scanned with CT again, the lesion was same as before. Lung function was evaluated via formal spirometry with a FEV1 of 3.54 L (105.1% predicted), a FVC of 4.25 L (97.7% predicted), a FEV1/ FVC ratio of 83. 28% and MVV of 113.43 L (113.2% predicted). The bronchoscopy was examined and had no significant positive findings, but the patient refused steadfastly CT-guided biopsy. Therefore, he was examined with a positron emission tomography and computerized tomography scan (PET-CT) preoperatively to ensure that there was no evidence of metastatic disease.
Surgery proceduresAs there are no changes for the lesion in the patient after standard anti-inflammatory treatment for two weeks, the density and form of GGO look like malignant lesion, moreover, the lesion located in the region of the hilar, and cannot be had wedge resection for frozen pathological examination, so we decided to make right middle lobectomy directly, and we had a radical lymphadenectomy after frozen pathology revealed adenocarcinoma.
Anesthesia and positioningThe patient was placed in the left lateral decubitus position with the upper arms extended to 90° and the forearms and hands covered his head without universal screen and arm board (Figure 2). To gain more operative space and protect the intercostal neurovascular bundles, a soft pillow was put under the left side of chest. General anesthesia was completed and intubation was achieved via a double lumen endobronchial tube. The surgeon and the assistant stood on both sides of the patient respectively to maintain the same thoracoscopic vision during all steps of surgery and to experience more coordinated movements. Usually, the surgeon held the suction tool in the left hand and the coagulation hook in the right hand. One assistant held the thoracoscope in two hands intently, another assistant operated endoscopic grasper and so on (Figure 3).
