ObjectiveTo explore the application of 5G remote robotic surgery in distal gastrectomy for gastric cancer and evaluate the feasibility and advantages of the “3+2” model “seven-step method”. MethodsThe situations at preoperative, intraoperative and postoperative follow-up of a patient who underwent 5G remote robotic distal gastrectomy for gastric cancer with “3+2” model “seven-step method” in Gansu Provincial People’s Hospital were summarized, and based on our experience of robotic surgery, the application advantages of “3+2” model “seven-step method” in 5G remote robotic distal gastrectomy for gastric cancer was explored. ResultsThe operative time of this case was 190 min, the intraoperative blood loss was 50 mL, the network delay was 43.554 ms, and no intraoperative adverse events occurred. After a one-year follow-up, the patient recovered well, with no complications, good diet and good quality of life. ConclusionsThe “3+2” model “seven-step method” is feasible for 5G remote robotic distal gastrectomy. Further research requires an increased sample size and extended follow-up period.
Objective To investigate the clinical application of da Vinci surgical system in nipple sparing mastectomy (NSM) and immediate one-stage implant-based breast reconstruction. Methods Five cases of breast cancer who underwent NSM and immediate implant-based breast reconstruction were analyzed from March 2022 to April 2022. Evaluation endpoints included the key points of operation, duration of surgery, postoperative complications, and patient-reported outcomes. Results Two patients underwent implant-based postpectoral breast reconstruction without mesh. Three patients received prepectoral reconstruction with biological mesh, 2 of which underwent bilateral breast reconstruction. Operating duration of 5 patients was 240–320 min, with an average of 291 min. The blood loss was 10–30 mL, with an average of 18 mL. No patient switched to open surgery due to the uncontrolled bleeding. The average drainage volume was 78 mL/d (60–100 mL/d) in the first 3 days and 38 mL/d (30–50 mL/d) in the 3 to 7 days after operation. The drainage tube was removed 10–18 days after operation, with an average of 13.2 days. No postoperative infections or nipple-areolar complex necrosis were observed. The inpatient stay was 1–3 days, with an average of 1.8 days. One month after operation, the BREAST-Q satisfaction score was 64–82, with an average of 76.20. The average cost for operation was 45 072 RMB (43 420–47 524 RMB). Conclusions The robotic NSM and immediate one-stage implant-based breast reconstruction is a safe procedure with better clinical outcomes and favorable patients’ satisfaction. However, the robotic system has longer operation time and higher cost. It still needs to be personalized in the clinical practice.
Thymectomy is an important treatment for thymoma and myasthenia gravis. The application of minimally invasive surgery to complete thymectomy and rapid recovery of patients after surgery is a developmental goal in thoracic surgery technology. Surgical robots have many technical advantages and are applied for many years in mediastinal tumor resections, a process that has led to its recognition. We published this consensus with the aim of examining how to ensure surgical safety based on the premise that better use of surgical robots achieving rapid recovery after surgery. We invited multiple experts in thoracic surgery to discuss the safety and technical issues of thymectomy under nonintubated anesthesia, and the consensus was made after several explorations and modifications.

Robotic gastric cancer surgery had developed rapidly in recent years, and its clinical application had come a long way. More and more studies had demonstrated that the robotic gastric cancer surgery was a safe and feasible procedure, and showed the technical advantages in the lymph node dissection, bleeding control, precise surgery, and postoperative recovery over laparoscopic surgery. However, some limitations such as the high surgical costs, lack of high-quality evidence, insufficient intelligence limited the development of robotic gastric cancer surgery. In the future, with more high-quality evidence-based medicine research and the development of intelligent surgical robots, the robotic gastric cancer surgery will be further standardized and promoted. We believe that robotic gastric cancer surgery will become the mainstream of minimally invasive surgery for the treatment of gastric cancer.
ObjectiveTo evaluate the efficacy of robotic intersphincteric resection (ISR) for rectal cancer.MethodsA literature search was performed using the China biomedical literature database, Chinese CNKI, Wanfang, PubMed, Embase, and the Cochrane library. The retrieval time was from the establishment of databases to April 1, 2019. Related interest indicators were brought into meta-analysis by Review Manager 5.2 software.ResultsA total of 510 patients were included in 5 studies, including 273 patients in the robot group and 237 patients in the laparoscopic group. As compared to the laparoscopic group, the robot group had significantly longer operative time [MD=43.27, 95%CI (16.48, 70.07), P=0.002], less blood loss [MD=–19.98.27, 95%CI (–33.14, –6.81), P=0.003], lower conversion rate [MD=0.20, 95%CI (0.04, –0.95), P=0.04], less lymph node harvest [MD=–1.71, 95%CI (–3.21, –0.21), P=0.03] and shorter hospital stay [MD=–1.61, 95%CI (–2.26, –0.97), P<0.000 01]. However, there were no statistically significant differences in the first flatus [MD=–0.01, 95%CI (–0.48, 0.46), P=0.96], time to diet [MD=–0.20, 95%CI (–0.67, 0.27), P=0.41], incidence of complications [OR=0.76, 95%CI (0.50, 1.14), P=0.18], distal resection margin [MD=0.00, 95%CI (–0.17, 0.17), P=0.98] and positive rate of circumferential resection margin [OR=0.61, 95%CI (0.27, 1.37), P=0.23].ConclusionsRobotic and laparoscopic ISR for rectal cancer shows comparable perioperative outcomes. Compared with laparoscopic ISR, robotic ISR has the advantages of less blood loss, lower conversion rate, and longer operation times. These findings suggest that robotic ISR is a safe and effective technique for treating low rectal cancer.
Objective To investigate application values and techniques of robot-assisted extended thymectomy for the treatment of typeⅠmyasthenia gravis （MG） using Da Vinci S system. Methods We retrospectively analyzed clinical data of 3 patients with MG who underwent robot-assisted extended thymectomy in General Hospital of Shenyang Military Command from March 2012 to September 2012. All the patients were ocular MG （typeⅠ） including 2 men （33 years and 66 years old respectively） and 1 woman （21 years old）. Surgical outcomes were analyzed. Results All the 3 patients successfully received robot-assisted extended thymectomy without accessorial incisions. None of the patients required converting to open sternotomy or postoperative reexploration for bleeding. Intraoperative blood loss was 5-10 ml．Overall operation time was95-138 minutes, and thymoma dissection time was 26-80 minutes. No myasthenic crisis or other major postoperative complic-ation occurred. Postoperative chest drainage duration was 3-9 days and postoperative hospital stay was 10-15 days. Two patientswere followed up for 6-12 months after discharge without MG recurrence. Conclusion Robot-assisted extended thymectomy is safe and feasible for the treatment of typeⅠMG with satisfactory results．
Objective To summarize the clinical data about mediastinal lesions, then to analyze the treatment effect of da Vinci robot system in the surgical treatment of mediastinal lesions. Methods We retrospectively analyzed the clinical data of 49 patients with mediastinal lesions in our hospital between January 2016 and October 2017. These patients were divided into two groups including a da Vinci robot group and a video-assisted thoracoscopic surgery (VATS) group according to the selection of the treatments. There were 25 patients with 14 males and 11 females at age of 56.5±17.9 years in the da Vinci group and 24 patient with 15 males and 11 females at age of 53.0±17.8 years in the VATS group. Results There was no statistical difference in surgery time between the two groups (t=–0.365, P=0.681). Less intraoperative blood loss (t=–2.569, P<0.001), less postoperative drainage amount within three days after surgery (t=–6.325, P=0.045), shorter period of bearing drainage tubes after surgery (t=–1.687, P=0.024), shorter hospital stays (t=–3.689, P=0.021), lower visual analogue scale (VAS) scores of postoperative 48 hours (t=–7.214, P=0.014) with a statistical difference in the da Vinci robot group compared with the VATS group. Conclusion The da Vinci robot system is safe and efficient in the treatment of mediastinal lesions compared with video-assisted thoracoscopic approach.
Objective To compare three surgical treatments for mediastinal mass with myasthenia gravis. Methods Retrospective analysis was performed on the clinical data of 53 patients who underwent extended thymectomy between January 2010 and December 2017 in our hospital. There were 29 males and 24 females, aged 17-73 years. Patients were divided into three groups according to the surgical methods: a group A (video-assisted thoracoscopic surgery with the da Vinci robotic system, n=22), a group B (video-assisted thoracoscopic surgery, n=12) and a group C (median sternotomy, n=19). The gender distribution, age, intraoperative blood loss, operation time, postoperative extubation time, postoperative hospital stay, Osserman classification of myasthenia gravis, postoperative myasthenic remission rate, etc were compared in three groups. Results No perioperative death was observed in 53 patients. One patient in the group C suffered from postoperative myasthenic crisis and improved after active treatment. One patient with video-assisted thoracoscopic surgery was converted to median sternotomy due to the intraoperative injury of the left brachiocephalic vein. Compared with the group B and group C, the group A had shorter operation time, less intraoperative blood loss and drainage on the first postoperative day and fewer days of extubation. Postoperative hospital stay was less in the group A than that in the group C (P<0.05). The postoperative myasthenic remission rate was higher in the group A than that in the other two groups, but there was no statistical difference. Conclusion Because of the robot’s unique minimally invasive advantage, in this study, the outcome of patients with myasthenia gravis treated with Da Vinci robots and thymectomy is better than that of the remaining two groups in terms of perioperative outcomes and myasthenic remission rate. But long-term results and a large of number matching experiments are needed to confirm. However, it is undeniable that robotic surgery must be the future of the minimally invasive surgery.
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.
