EARLY RESULTS OF ROBOTIC LOBECTOMY TREATMENT NON-SMALL CELL LUNG CANCER: EXPERIENCE AT CHO RAY HOSPITAL

Abstract

Objectives: Nowadays, there are numerous ways to configure trocar placements for lobectomy using the Da Vinci Xi system. Cho Ray Hospital conducted robotic video-assisted thoracic surgery (rVATS) lobectomy in July 2018 and obtained satisfactory results. Currently, there is no research on rVATS lobectomy in Vietnam, so we decided to report our initial experiences using rVATS lobectomy in non-small cell lung cancer at our institute. Subjects and methods: rVATS for lobectomy was performed on 79 patients with lung cancer who were treated at Cho Ray Hospital from July 2018 to June 2022. All patients were performed the rVATS lobectomy with triangular port placement. The cardiere, harmonic arms were used as robotic arms in the present study which was further coordinated with thoracic surgical instruments through working support. The early outcomes were: The rate of conversion to open procedure, post-operative complications, and day of post-operation. Results: Out of 79 enrolled patients, the majority of study participants were males and belonged to the 60 - 69 years age group. Most of them had tumor lesions in the left upper lobe, followed by the right upper lobe and right lower lobe, respectively. The mean tumor size was noted to be 3.8 cm. The mean time of operation was 262.2 minutes. The average blood loss was 200 mL. The rate of conversion to open procedure accounted for 8.9%. In intraoperative lymphadenectomy for the mediastinal lymph node, the resection rate was 74.7%. Amongst postoperative complications, prolonged air leak > 7 days was the most common. In the hospital, mortality was found to be 1.3%. Changes in clinical and pathological lymph node assessment via intraoperative lymph node dissection accounted for 32.9%.
