Brief Summary

Video-assisted thoracic surgery (VATS) has been recommended by clinical guidelines as one of the preferred surgeries for early-stage non-small cell lung cancer (NSCLC) for many years. However, VATS has inherent drawbacks, so at the beginning of this century, robotic-assisted thoracoscopic surgery (RATS) was first applied for lung resection. In recent years, RATS has developed rapidly, but there are still many unsolved scientific problems in the field of RATS. Thus, a multicenter prospective randomized controlled trial was conducted with stage I-II NSCLC patients as the study subject and 5-year DFS as the primary endpoint to compare the short-term and long-term outcomes of RATS and VATS in the treatment of early-stage NSCLC.

Blood lossDuring the surgery

Blood loss during the surgery

Conversion rateDuring the surgery

The number of patients converted to thoracotomy divided by the total number of included patients in a group

Perioperative complicationThe day of surgery, 2/4/8/12/26/52 weeks after surgery

Intraoperative and postoperative complications

Operative death rate30/90 days after surgery

The number of patients died within 30/90 days after surgery divided by the total number of included patients in a group

Hospital stays after surgeryBetween the date of surgery and the date of discharge, assessed up to 30 days

The length of stay in hospital after surgery

R0 ratePostoperative in-hospital stay up to 30 days

The number of patients received R0 surgery divided by the total number of included patients in a group

Pain score after surgeryScores were given daily after surgery and at weeks 2/4/8/12/26/52 after discharge

The degree of pain after surgery was measured using Numerical Rating Scale (NRS). The patient is asked to make three pain ratings, corresponding to current, best and worst pain experienced over the past 24 hours on a scale of 0 (no pain) to 10 (worst pain imaginable). The average of the 3 ratings was used to represent the patient's level of pain over the previous 24 hours.

Operative timeDuring the surgery

The total time from skin to skin and the time of each step were recorded

Acesodyne (Grade III) dosePostoperative in-hospital stay up to 30 days

The total amount of morphine used by the patient during the postoperative hospital stay, including morphine, pethidine, and fentanyl etc.

Total cost of hospitalizationFrom the date of admission to the date of discharge, assessed up to 30 days

The total cost of the patient from admission to discharge

The number of resected lymph nodesPostoperative in-hospital stay up to 30 days

The number of resected lymph nodes were calculated according to the official pathological report after surgery

Chest tube durationPostoperative in-hospital stay up to 30 days

The number of days between the date of surgery and the date of chest tube removal
