ObjectiveTo systematically review the efficacy and safety of robotic-assisted thoracic surgery (RATS) and video assisted thoracic surgery (VATS) for patients with non-small cell lung cancer (NSCLC). MethodsWe searched PubMed, EMbase, The Cochrane Library (Issue 9, 2016), Web of Science, CNKI, VIP, WanFang Data and CBM databases to collect clinical studies about RATS vs. VATS for patients with NSCLC from inception to October 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 14 cohort studies involving 19 921 patients were included; among them, 4 322 cases were in the RATS group, and 15 599 were in the VATS group. The results of meta-analysis showed that the operation time (MD=22.90, 95%CI 9.97 to 35.84, P<0.000 5) was longer in the RATS group than the VATS group. However, the conversion rate (OR=0.72, 95%CI 0.44 to 1.18, P=0.20), the incidence of postoperative complications (OR=1.06, 95%CI 0.96 to 1.17, P=0.28), intraoperative blood loss (MD=2.75, 95%CI –8.39 to 13.89, P=0.63), postoperative hospitalization time (MD=–0.00, 95%CI –0.02 to 0.02, P=0.99) and in-hospital mortality rate (OR=0.60, 95%CI 0.35 to 1.05, P=0.07) were not significant differences between both groups.ConclusionThe current meta-analysis indicates that the efficacy and safety of RATS and VATS for NSCLC is equivalence, however the operation time for RATS is longer. Due to the limited quantity and quality of inclued studies, the above conclusions still need to be verified by more high quality studies.
At present, the application of the robot assisted surgery system in the surgical treatment of esophageal cancer is gradually emerging, and it is more and more widely used and recognized in the field of surgery. According to the domestic and foreign literatures, the robot has many advantages, and robotic assisted esophageal cancer surgery has been proved to be safe and effective, and its short-term efficacy is significantly better than thoracotomy. Other studies have shown that in long-term follow-up, the effect is comparable to video-assisted thoracoscopic surgery. In this paper, the author are systematically reviewed the development history of the robot assisted surgery system, the effect of robotic assisted esophagectomy on safety, surgical method, short-term efficacy and long-term prognosis. The traditional open surgery and thoracoscopic laparoscopic esophagectomy has been carried on the detailed comparison to provide some advice and theoretical basis for esophageal cancer surgery robot system.
Objective To explore the advantages and effectiveness of the independently developed intelligent orthopedic robot-assisted distal locking of femoral intramedullary nails. Methods Thirty-two adult cadaveric femur specimens were randomly divided into two groups, with 16 specimens in each group. The experimental group used the intelligent orthopedic robot to assist in the distal locking of femoral intramedullary nail holes, while the control group used the traditional method of manual locking under X-ray fluoroscopy. The locking time, fluoroscopy times, and the success rate of first locking were recorded and compared between the two groups. Results The locking time of the experimental group was (273.94±38.67) seconds, which was shorter than that of the control group [(378.38±152.72) seconds], and number of fluoroscopies was (4.56±0.81) times, which was less than that of the control group [(8.00±3.98) times]. The differences were significant [MD=73.054 (−37.187, 85.813), P=0.049; MD=1.969 (−1.437, 2.563), P=0.002]. The first locking success rate of the experimental group was 100% (16/16), which was significantly higher than that of the control group (68.75%, 11/16) (P=0.043). ConclusionThe efficiency of distal locking of femoral intramedullary nails assisted by the intelligent orthopedic robot is significantly higher than that of the traditional manual locking method under fluoroscopy, as it can markedly reduce the time required for distal locking of femoral intramedullary nails, decrease intraoperative radiation exposure, and increase the success rate of locking.
