Continuous 389 cases of Da Vinci robot-assisted thoracoscopic lobectomy in treatment of non-small cell lung cancer: experience in Shanghai Chest Hospital.

Abstract

To analyze the perioperative indexes of 389 patients with non-small cell lung cancer in single center after robot-assisted thoracoscopic (RATS) lobectomy, and to summarize the surgical key points in robotic lobectomy. The clinical data of 389 stage I non-small cell lung cancer patients who underwent RATS lobectomy from May 2013 to December 2016 were retrospectively analyzed. Among them, there were 261 females (67.1%) and 128 males (32.9%); aged from 20-76 years old, with a mean age of 55.01 years; with ASA I in 106 cases, ASA II in 267 cases and ASA III in 16 cases; with BMI from 16.87-34.05, averaged at 23.09±2.79. The largest tumor in preoperative chest CT measurement was 0.3-3.0 cm, ranging from 1.29±0.59 cm; with stage Ia in 153 cases, stage Ib in 148 cases, stage Ic in 32 cases, stage IIb in 26 cases and stage IIIa in 30 cases; including 380 adenocarcinomas and 9 squamous carcinomas. The operating time was 46-300 min, averaged at 91.51±30.80 min; with a blood loss of 0-100 mL in 371 cases (95.80%), 101-400 mL in 12 cases (3.60%) and >400 mL in 2 cases (0.60%); there were 4 (1.2%) conversions to thoracotomy, in which 2 patients had massive hemorrhage and 2 patients had extensive dense adhesion; there was no mortality during operation and perioperatively. The drainage on the first day after operation was 0-960 mL, averaged at 231.39±141.87 mL; the postoperative chest tube was placed for 2-12 d, averaged at 3.96±1.52 d; the postoperative hospital stay was 2-12 d, averaged at 4.96±1.51 d, with postoperative hospital stay >7 d in 12 cases (3.60%). The postoperative air leakage was the main reason (35 cases, 9%) for prolonged hospital stay, and there was no re-admitted case within 30 days. All the patients underwent systemic lymph node dissection. The total cost of hospitalization was 60,389.66-134,401.65 CNY, averaged at 93,809.23±13,371.26 CNY. The application of Da Vinci robot surgery system in resectable non-small cell lung cancer is safe and effective, and could make up for the deficiencies of traditional thoracoscopic surgery. The number and level of robot surgery in our center have reached international advanced level, but the relatively expensive cost has become a major limitation in limiting its widespread use. With continuous improvements in robotic technology, its scope of application will be wider, which will inevitably bring new insights in lung surgical technology.
