Objective To investigate the perioperative outcome of robot-assisted pulmonary lobectomy in treating pathological stage Ⅰ non-small cell lung cancer (NSCLC). Methods We retrospectively analyzed the clinical data of 333 consecutive p-T1 NSCLC patients who underwent robotic-assisted pulmonary lobectomy in our hospital between May 2013 and April 2016. There were 231 females (69.4%) and 102 males (30.6%) aged from 20–76 (55.01±10.46) years. Cancer was located in the left upper lobectomy in 37 (11.1%) patients, left lower lobectomy in 71 (21.3%) patients, right upper lobectomy in 105 (31.5%) patients, right middle lobectomy in 32 (9.6%) patients, right lower lobectomy in 88 (26.4%) patients. Adenocarcinoma was confirmed in 330 (99.1%) patients and squamous cell cancer was confirmed in 3 (0.9%) patients. Results Total operative time was 46–300 (91.51±30.80) min. Estimated intraoperative blood loss was 0–100 ml in 319 patients (95.8%), 101–400 ml in 12 patients (3.6%), >400 ml in 2 patients (0.6%). Four patients were converted to thoracotomy, including 2 patients due to pulmonary artery branch bleeding and 2 due to pleural adhesion.No patient died within 30 days after surgery. And no perioperative blood transfusion occurred. Postoperative day 1 drain was 0–960 (231.39±141.87) ml. Chest drain time was 2–12 (3.96±1.52) d.And no patient was discharged with chest tube. Length of hospital stay after surgery was 2–12 (4.96±1.51) d. Persistent air leak was in 12 patients over 7 days. No readmission happened within 30 days. All patients underwent lymph node sampling or dissection with 2–9 (5.69±1.46) groups and 3–21 (9.80±3.43) lymph nodes harvested. Total intraoperative cost was 60 389.66–134 401.65 (93 809.23±13 371.26) yuan. Conclusion Robot-assisted pulmonary lobectomy is safe and effective in treating p-Stage Ⅰ NSCLC, and could be an important supplement to conventional VATS. Regarding to cost, it is relatively more expensive compared with conventional VATS. RATS will be widely used and make a great change in pulmonary surgery with the progressive development of surgical robot.
ObjectiveTo present the initial clinical experience of robot-assisted thoracoscopic esophagectomy for patients with esophageal cancer and to analyze the short-term outcomes of these patients.MethodsBetween February 2016 and December 2017, 148 patients with esophageal carcinoma underwent robotic esophagectomy and two-fields lymph node dissection. There were 126 males and 22 females at average age of 62.0±8.0 years. Demographic data, intraoperative characteristics and short-term surgical outcomes were collected and analyzed.Results106 patients underwent McKeown esophagectomy and 42 patients underwent Ivor-Lewis esophagectomy. The mean operation time was 336.0±76.0 min, the mean intraoperative blood loss was 130.0±89.0 ml, the mean number of lymph nodes removed was 21.0±8.0 and the mean length of postoperative hospital-stay was 12.0±7.2 days. Postoperative complications included anastomotic fistula (n=8, 5.4%), pulmonary infection (n=13, 8.7%), hoarseness (n=23, 15.5%), tracheoesophageal fistula (n=1, 0.7%), chylothorax (n=4, 2.7%) and incision infection (n=2, 1.4%). There was no intra-operational massive hemorrhage or in-hospital mortality.ConclusionBoth robot-assisted McKeown and Ivor-Lewis esophagectomy are safe and feasible with good early outcomes.
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.
ObjectiveTo compare the perioperative results of hybrid coronary revascularization (HCR), off-pump coronary artery bypass (OPCAB) and percutaneous coronary intervention (PCI) in elderly patients with three-vessel coronary artery disease involving left anterior descending (LAD) branch and explores the safety of surgery.MethodsWe prospectively enrolled patients with coronary heart disease over 65 years who were admitted to General Hospital of People’s Liberation Army from January 2018 to September 2019. Coronary angiography results were all three-vessel lesions involving the anterior descending artery. After preoperative examination and assessment by the cardiovascular team, all patients were suitable for OPCAB or PCI treatment. According to the patient’s preference, HCR, OPCAB or PCI were performed. The preoperative baseline data and perioperative results were collected, and SPSS 22.0 was used for statistical analysis.ResultsA total of 110 patients met the criteria and were included in the study, 28 in the HCR group, 45 in the OPCAB group, and 37 in the PCI group, with an average age of 71.4±5.6 years. There was no statistical difference in the preoperative baseline data of patients among the three groups. The intubation time (P=0.039), perioperative drainage volume (P<0.001), blood transfusion (P=0.021) in the HCR group were lower than those in the OPCAB group. There was no statistical difference in the main organ adverse events (MOAE, P=0.096) and in-hospital mortality (P=0.784) among the three groups of patients. The use of antibiotics in the PCI group was significantly lower than the other two groups (P<0.001).ConclusionHCR combines the advantage of CABG and PCI including proved long-term patency rate with left internal mammary artery-LAD grafting, less trauma and superior long-term patency with PCI in non-LAD territory. Compared with OPCAB and PCI, there is no increase in perioperative major organ adverse events and in-hospital mortality. It is a safe and reliable minimally invasive myocardial revascularization technique for elderly patients with three-vessel coronary artery disease involving the anterior descending artery.

No death occurred during the perioperative period. Postoperative complications occurred in 12 cases (6.7%, 12/180) and 2 cases died (1.1%, 2/180). Conclusionsda Vinci surgical system can carry out all kinds of general surgery, especially complicated and difficult hepatobiliary and pancreatic surgery, which improves the development of minimally invasive surgery.
ObjectiveTo review the current status of da Vinci surgical system in vascular surgery. MethodsRecent literatures published in Chinese or English about the application of da Vinci surgical system in vascular surgery were reviewed and analyzed. Resultsda Vinci surgical system was mainly applied in diseases such as aortoiliac occlusive disease, aneurysm, typeⅡ endoleak after endovascular aortic repair, celiac artery compression syndrome, and so on. It was used to expose arteries, or assist to ligate and dissect arteries. da Vinci surgical system showed apparent advantages in shorting the time of aortic clamping, however, the high cost, the loss of tactile feedback, and the long learning curve may be its shortcomings. Conclusionda Vinci surgical system is safe and effective in vascular surgery, while much more experience is required to evaluate its long-term effect and complication.
ObjectiveTo summarize our initial experience in robot-assisted left upper lobectomy for non-small cell lung cancer. MethodsFour patients with non-small cell lung cancer underwent robot-assisted left upper lobectomy with da Vinci S surgical system (Intuitive Surgical, California) in General Hospital of Shenyang Military Area Command between March and August 2013. There were 3 male and 1 female patients, and their age was 58.8 years (range:49-67 years). We used general anesthesia with double lumens trachea cannula. The patients set in right lateral decubitus position with jackknife. We used 3 arms of the robot system. A single direction lobectomy procedure or an anatomic lobectomy procedure was used according to the differentiation of fissure. Systemic lymph node dissection was performed for all patients. ResultsFour patients with left upper lobectomy were completed with total robotic procedure without conversion. Postoperative pathological examination showed all the patients were of all adenocarcinoma with 2 patients inⅠA stage and 2 patients inⅢA stage. The range of operating time was 100-150 min, intraoperative blood loss was 30-80 ml and no blood transfusion was needed for the patients. The drainage time was 6-20 days. All of the 4 patients were discharged smoothly. The patients were followed up for 10-15 months without recurrence or metastasis. ConclusionRobot-assisted left upper lobectomy is safe and feasible for non-small cell lung cancer.
Objective To investigate the clinical effect of digital drainage system (DDS) in patients after robot-assisted lobectomy. MethodsThe clinical data of the patients who underwent da Vinci robot-assisted lobectomy from August 2020 to December 2021 were retrospectively analyzed. The patients were divided into a DDS group and a conventional group (using traditional single thoracic drainage tube device) according to different drainage devices used after operation. The preoperative data, intraoperative blood loss, total drainage volume within 48 h after operation, postoperative extubation time and postoperative hospital stay were compared between the two groups. ResultsFinally, 170 patients were collected, including 76 males and 94 females with an average age of 61.8±8.7 years. Postoperative extubation time [5.53 (6.00, 7.00) days vs. 6.36 (6.00, 8.00) days, Z=–2.467, P=0.014] and postoperative hospital stay [7.80 (8.00, 10.00) days vs. 8.94 (9.00, 10.00) days, Z=–2.364, P=0.018] in the DDS group were shorter than those in the conventional group. For patients with postoperative persistent air leak, postoperative extubation time (Z=–2.786, P=0.005) and postoperative hospital stay (Z=–2.862, P=0.003) in the DDS group were also shorter than those in the conventional group. ConclusionDDS has a positive effect on enhanced recovery after robot-assisted lobectomy, which is safe and stable, and is beneficial to postoperative rehabilitation and shortening the average hospital stay.
ObjectiveTo discuss the feasibility, safety, and superiority of da Vinci surgery system (DVSS) in liver tumor resection. MethodThe clinical data of 21 patients who underwent DVSS in the liver tumor resection were analyzed retrospectively. ResultsThere were 12 patients with hepatocellular carcinoma (HCC), 1 patient with cholang-iocellular carcinoma, 1 patient with hepatic cirrhosis regenerative nodule, 2 patients with metastatic adenocarcinoma, 2 patients with leiomyosarcoma, and 3 patients with cavernous hemangioma.The operative time was (156.67±92.19) min (60-480 min), the intraoperative blood loss was (585.71±1 076.12) mL (50-5 000 mL), the time of diet recovery was (3.23±1.26) d (2-6 d), and the hospital stay was (10.10±9.02) d (5-47 d).The hospital mortality and morbidity rates were 0(0/21) and 9.52%(2/21) respectively including 1 patient with biliary leakage and 1 patient with abdominal infection. ConclusionThis study demonstrates the feasibility and safety of DVSS in the liver tumor resection and the system has a wide range of application for patients who are suffering from liver tumor.
ObjectiveTo explore the factors that affect the drainage time of da Vinci robot lung cancer surgery, to analyze the coping strategies, and to provide a basis for shortening the drainage time of patients after surgery and speeding up the patients' recovery.MethodsThe clinical data of 131 patients who underwent da Vinci robot lung cancer surgery at the Department of Thoracic Surgery, General Hospital of Northern Theater Command from January 2019 to October 2019 were retrospectively analyzed. Among them, 68 were males and 63 were females, with an average age of 59.84±9.66 years. According to the postoperative thoracic drainage time, the patients were divided into two groups including a group A (drainage time≤ 5 days) and a group B (drainage time >5 days). Univariate analysis and logistic multivariate regression analysis were used to analyze the factors that may affect postoperative drainage time, and the correlation between different influencing factors and thoracic drainage time after da Vinci robot lung cancer surgery.ResultsLogistic multivariate analysis showed that age≥60 years (P=0.014), diabetes mellitus (P=0.035), operation time≥130 min (P=0.018), number of lymph node dissections≥15 (P=0.002), and preoperative albumin<38.45 g/L (P=0.010) were independent factors affecting the drainage time of da Vinci robot lung cancer surgery.ConclusionFor elderly patients with diabetes mellitus during the perioperative period, blood glucose should be actively controlled, reasonable surgical strategies should be formulated to ensure the safety and effectiveness of the operation, while reducing intraoperative damage and shortening the operation time. After the operation, patients should be guided to strengthen active coughing, expectoration and lung expansion. Thereby it can shorten drainage time and speed up the recovery of patients after operation.
