ObjectiveTo systematically review the clinical utilization of robotic bronchoscopes in diagnosis of pulmonary nodules, including MonarchTM and IonTM platforms, and then evaluate the efficacy and safety of the procedure. MethodsPubMed, EMbase, Web of Science and Cochrane Central Register of Controlled Trials databases were searched by computer for literature about the biopsy of pulmonary nodules with robotic bronchoscope from January 2018 to February 14, 2022. The quality of research was evaluated with Newcastle-Ottawa Scale. RevMan 5.4 software was used to conduct the meta-analysis. ResultsFinally, 19 clinical studies with 1 542 patients and 1 697 targeted pulmonary nodules were included, of which 13 studies used the IonTM platform and 6 studies used the MonarchTM platform. The overall diagnostic rate of the two systems was 84.96% (95%CI 62.00%-95.00%), sensitivity for malignancy was 81.79% (95%CI 43.00%-96.00%), the mean maximum diameter of the nodules was 16.22 mm (95%CI 10.98-21.47), the mean procedure time was 61.86 min (95%CI 46.18-77.54) and the rate of complications occurred was 4.76% (95%CI 2.00%-15.00%). There was no statistical difference in the outcomes between the two systems. Conclusion Robotic bronchoscope provides a high efficacy and safety in biopsy of pulmonary nodules, and has a broad application prospect for pulmonary nodules diagnosis.
ObjectiveTo systematically review the efficacy and safety of robotic-assisted hepatectomy (RAH) versus traditional laparoscopic hepatectomy (TLH) for hepatic neoplasms.MethodsDatabases including PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, WanFang Data and CBM databases were electronically searched to collect cohort studies about the RAH vs. the TLH for liver neoplasms from inception to December 10th, 2016. Two reviewers independently screened the literatures, extracted data and assessed the risk of bias of the included studies. And finally, a meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 17 studies involving 1 389 patients were included. The meta-analysis results showed that: compared to TLH group, RAH group was associated with more estimated blood loss (WMD=39.56, 95%CI 4.65 to 74.47, P=0.013), longer operative time SMD=0.55, 95%CI 0.29 to 0.80, P<0.001), and later in the first nutritional intake time (SMD=1.06, 95%CI 0.66 to 1.45,P<0.001). However, there were no significant differences in the length of hospital stay, conversion to laparotomy, intraoperative blood transfusion, resection rate of tumor margin, complications and 90-day mortality between the two groups.ConclusionCurrent evidence indicates that TLH is superior to RAH in terms of operative time, intraoperative blood loss and the first nutritional intake time, but there are no statistically significant differences in the primary outcomes, suggesting that RAH and TLH have similar efficacy and safety for hepatic neoplasms. Due to the limitation of quality and quantity of the included studies, the above conclusions need to be verified by more high-quality research.
This study reports the first successful clinical application of a robotic-assisted system in transcatheter balloon-expandable aortic valve implantation using the Edwards SAPIEN 3 valve. Two male patients, aged 60 and 63 years, respectively, presented with severe aortic stenosis confirmed by echocardiography and computed tomography, showing significant valvular calcification and elevated transvalvular pressure gradients, meeting the indications for transcatheter aortic valve implantation (TAVI). Both procedures were performed via the right femoral artery using a robotic-assisted delivery and positioning system developed by Shanghai Surgerii Medical Technology Co., Ltd. The operator controlled the delivery system and valve positioning precisely through the console, while the assistant performed balloon expansion and valve deployment. Both procedures were completed successfully without intraoperative complications. The operative times were 75 minutes and 67 minutes, with fluoroscopy times of 16 minutes and 23 minutes, and radiation doses of 714 mGy and 971 mGy, respectively. Postoperative echocardiography demonstrated well-functioning prosthetic valves, with mean transvalvular pressure gradients of 3.9 mm Hg and 8.0 mm Hg, and none or trivial paravalvular leakage. No coronary obstruction, conduction disturbance, or vascular complications were observed. This report represents the world’s first clinical use of a robotic-assisted system for balloon-expandable TAVI. It confirms the feasibility and safety of robotic assistance in transcatheter valve delivery and positioning, offering a new approach to enhance procedural precision and stability, and providing valuable insights for the future development of intelligent, minimally invasive therapies for structural heart disease.
Objective To systematically review the efficacy of robotic, laparoscopic-assisted, and open total mesorectal excision (TME) for the treatment of rectal cancer. Methods The PubMed, EMbase, The Cochrane Library, and ClinicalTrials.gov databases were electronically searched to identify cohort studies on robotic, laparoscopic-assisted, and open TME for rectal cancer published from January 2016 to January 2022. Two reviewers independently screened the literature, extracted data, and evaluated the risk of bias of the included studies. Subsequently, network meta-analysis was performed using RevMan 5.4 software and R software. Results A total of 24 studies involving 12 348 patients were included. The results indicated that among the three types of surgical procedures, robotic TME showed the best outcomes by shortening the length of hospital stay, reducing the incidence of postoperative anastomotic fistula and intestinal obstruction, and lowering the overall postoperative complication rate. However, differences in the number of dissected peritumoural lymph nodes were not statistically significant. Conclusion Robotic TME shows better outcomes in terms of the radicality of excision and postoperative short-term outcomes in the treatment of rectal cancer. However, clinicians should consider the patients’ actual condition for the selection of surgical methods to achieve individualised treatment for patients with rectal cancer.
ObjectiveTo analyze the risk factors for complications after robotic segmentectomy.MethodsClinical data of 207 patients undergoing robot-assisted anatomical segmentectomy in our hospital from June 2015 to July 2019 were retrospectively analyzed, including 69 males and 138 females with a median age of 54.0 years. The relationship between clinicopathological factors and prolonged air leakage, pleural effusion, and pulmonary infection after surgery was analyzed.ResultsAfter robot-assisted segmentectomy, 20 (9.7%) patients developed prolonged air leakage (>5 d), 17 (8.2%) patients developed pleural effusion, and 4 (1.9%) patients developed pulmonary infection. Univariate logistic regression showed that body mass index (BMI, P=0.018), FEV1% (P=0.024), number of N1 lymph nodes resection (P=0.008) were related to prolonged air leakage after robot-assisted segmentectomy. Benign lesion was a risk factor for pleural effusion (P=0.013). The number of lymph node sampling stations was significantly related to the incidence of pulmonary infection (P=0.035). Multivariate logistic analysis showed that the BMI (OR=0.73, P=0.012) and N1 lymph node sampling (OR=1.38, P=0.001) had a negative and positive relationship with prolonged air leakage after robot-assisted segmentectomy, respectively.ConclusionThe incidence of pulmonary complications after robot-assisted segmentectomy is low. The lower BMI and more N1 lymph node sampling is, the greater probability of prolonged air leakage is. Benign lesions and more lymph node sampling stations are risk factors for pleural effusion and lung infection, respectively. Attention should be paid to the prevention and treatment of perioperative complications for patients with such risk factors.
ObjectiveTo explore the application effect of the individualized preoperative visit to the da Vinci Robotic lobectomy patients.
MethodSixty lobectomy patients with 34 males and 26 females at age of 29 to 78 (58.4±12.4) years were divided into two groups according to the order of their medical treatment in our hospital between June 2014 and December 2014. In the control group we used conventional reoperative visit method, while in the observation group we used individualized preoperative visit method. And the rehabilitation effects of the two groups were compared.
ResultsPostoperative drainage tube time (6.17±1.34 d vs. 7.13±1.17 d, P=0.004) and length of hospital stay (7.13±1.17 d vs. 8.37±1.92 d, P=0.004) were significantly shorter in the observation group than those in the control group. Postoperative pain score was significantly lower in the observation group than that in the control group (0.87±0.73 points vs. 2.60±0.81 points, P=0.000). Also in the observation group the patients had a higher degree of satisfaction with a statistical difference (P<0.05).
ConclusionIndividualized preoperative visit relieves patients' concern of the effect of the robotic operation, effectively reduces the psychological pressure of patients, strengthens the confidence of patients to overcome the disease, so that patients can actively cooperate with the operation, which promote postoperative rehabilitation.
Objective To investigate the risk factors for arrhythmia after robotic cardiac surgery. Methods The data of the patients who underwent robotic cardiac surgery under cardiopulmonary bypass (CPB) from July 2016 to June 2022 in Daping Hospital of Army Medical University were retrospectively analyzed. According to whether arrhythmia occurred after operation, the patients were divided into an arrhythmia group and a non-arrhythmia group. Univariate analysis and multivariate logistic analysis were used to screen the risk factors for arrhythmia after robotic cardiac surgery. ResultsA total of 146 patients were enrolled, including 55 males and 91 females, with an average age of 43.03±13.11 years. There were 23 patients in the arrhythmia group and 123 patients in the non-arrhythmia group. One (0.49%) patient died in the hospital. Univariate analysis suggested that age, body weight, body mass index (BMI), diabetes, New York Heart Association (NYHA) classification, left atrial anteroposterior diameter, left ventricular anteroposterior diameter, right ventricular anteroposterior diameter, total bilirubin, direct bilirubin, uric acid, red blood cell width, operation time, CPB time, aortic cross-clamping time, and operation type were associated with postoperative arrhythmia (P<0.05). Multivariate binary logistic regression analysis suggested that direct bilirubin (OR=1.334, 95%CI 1.003-1.774, P=0.048) and aortic cross-clamping time (OR=1.018, 95%CI 1.005-1.031, P=0.008) were independent risk factors for arrhythmia after robotic cardiac surgery. In the arrhythmia group, postoperative tracheal intubation time (P<0.001), intensive care unit stay (P<0.001) and postoperative hospital stay (P<0.001) were significantly prolonged, and postoperative high-dose blood transfusion events were significantly increased (P=0.002). Conclusion Preoperative direct bilirubin level and aortic cross-clamping time are independent risk factors for arrhythmia after robotic cardiac surgery. Postoperative tracheal intubation time, intensive care unit stay, and postoperative hospital stay are significantly prolonged in patients with postoperative arrhythmia, and postoperative high-dose blood transfusion events are significantly increased.
Recently, anatomical segmentectomy emerges as a hot spot in clinical research for surgical treatment of early-stage lung cancer. The techniques of segmentectomy are more elaborate and complicated than lobectomy, because of the considerable anatomic variations of segment blood vessels and bronchus. In a long term, video-assisted thoracic surgery is the mainly minimally invasive approach. As a new approach of minimally invasive surgery, da Vinci robot system possesses three-dimensional and high definition view, better dexterity mechanical wrist and tremor filtering system, which are the main advantages over video-assisted thoracic surgery. All the superiorities of robot system provide good supports for performing segmentectomy. Robot-assisted segmentectomy has been carried out in many medical centers in China and abroad until now. However, most surgery cases often lack adequate controls on quality.
Objective?To approach feasibility, safety, and the application range of pure laparoscopic resection （PLR）, hand-assisted laparoscopic resection （HALR）, and robotic liver resection （RLR） in the minimally invasive liver resection （MILR）. Methods?The clinical data of 128 patients underwent MILR in the Surgical Department of the Shanghai Ruijin Hospital from September 2004 to January 2012 were analyzed retrospectively. According to the different methods, the patients were divided into PLR group, HALR group, and RLR group. The intraoperative findings and postoperative recovery of patients in three groups were compared.?Results?There were 82 cases in PLR group, 3 cases of which were transferred to open surgery；the mean operating time was （145.4±54.4） minutes （range：40-290 minutes）；the mean blood loss was （249.3±255.7） ml （range：30-1 500 ml）；abdominal infection was found in 3 cases and biliary fistula in 5 cases after operation, but all recovered after conservative treatment；the mean length of hospital stay was （7.1±3.8） days （range：2-34 days）. There were 35 cases in HALR group, 3 cases of which were transferred to open surgery；the mean operating time was （182.7±59.2） minutes （range：60-300 minutes）；the mean blood loss was （754.3±785.2） ml （range：50-3 000 ml）；abdominal infection was found in 1 case, biliary fistula in 2 cases, and operative incision infection in 2 cases after operation, but all recovered after conservative treatment；the mean length of hospital stay was （15.4±3.7） days （range：12-30 days）. There were 11 cases in RLR group, 2 cases of which were transferred to open surgery； the mean operating time was （129.5±33.5） minutes （range：120-200 minutes）； the mean blood loss was （424.5±657.5） ml （range：50-5 000 ml）； abdominal infection was found in 1 case and biliary fistula in 1 case after operation, but all recovered after conservative treatment； the mean length of hospital stay was （6.4±1.6） days （range：5-9 days）. The operating time （P=0.001） and length of hospital stay （P=0.000） of the RLR group were shortest and the blood loss （P=0.000） of the PLR group was least among three groups. Conclusions?Minimally invasive resection is a safe and feasible. Different surgical procedures should be chosen according to different cases. The robotic liver resection provides new development for treatment of liver tumor.
