Uniportal video-assisted thoracic surgery (VATS) anatomical pulmonary resection, with only one small incision for surgery instruments and camera insertion, requires higher operative skills, especially in the cases of the enlarged pulmonary hilar lymph nodes. With improved technology and increased experiences in VATS lobectomy, uniportal VATS lobectomy has been applied in major medical centers recently. A 67-year-old male patient with left upper peripheral lung cancer and enlarged hilar lymph nodes underwent unipotal VATS lobectomy and systemic mediastinal lymph node dissection. The patient recovered uneventfully. (Figure 1). Preoperative pathological examination of the lung lesion obtained by CT-guided percutaneous transthoracic needle biopsy indicated a poorly differentiated squamous cell carcinoma. The patient had coronary heart disease and the coronary artery DSA indicated 50% stenosis in left anterior descending (LAD). Left upper pulmonary lobectomy was performed. The operation took 171 minutes. During the operation, the estimated blood loss was 100 mL.On postoperative day (POD) 1, the amount of fluid drainage was 350 mL, and chest X-ray showed satisfied left lung inflation (Figure 2). The chest tube was removed on POD 4. The patient was discharged on POD 6 without complications. The tumor size was 4 cm in diameter, and the postoperative pathology confirmed lymph metastasis in station 5 ,11 and 13. Four cycles of adjuvant chemotherapy and radiotherapy were followed.
Operative techniquesOperative position, insicion and instruments: the uniportal insicion were performed between the anterior axillary line and posterior axillary line over the fourth intercostal space about 4 cm in length ( Figure 3A). No rib spreader was used. A disposable, plastic wound retractor was used to stretch and protect the incision ( Figure 1B). A 30-degree, 10-mm high definition camera thoracoscope was placed at the posterior part of the incision during operation time for a panoramic view. To relieve the camera-man's hand tiredness, the thoracoscope bounded by a tape was fixed to the surgical drape ( Figure 3B). Both the surgeon and the camera-man stood in front of the patient and shared the same vision. VATS uses the same instruments as the conventional 3-port VATS dose (Figure 4). During dissection, we held a curving suction (Panther Healthcare, China) in left hand and an electrocautery hook or an ultra-sonic scalpel in the right hand.Operative key points and procedure ( Figure 5) (I) Mobilization of pulmonary vessels. The patient's interlobar fissure was complete. First we dissected the pulmonary artery in the interlobar fissure with ultrasonic scalpel or electrocautery hook and stapled the lingular atrey with a vascular (white cartridge, 45-mm-long) endostapler (EndoGIA, Covidien, USA). Then we dissected the interlobar lymph nodes (station 11). After the dissection of inter lobar fissure, the mediastinal pleura of the upper and anterior hilum was separated to isolate the anterior and apical segmental pulmonary arteries...
