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 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.
ObjectiveTo summarize the surgical learning curve and evaluate the effectiveness, safety and feasibility of the robotic-assisted thoracoscopic surgery (RATS) by comparing with the conventional vedio-assisted thoracoscopic surgery (VATS).MethodsThe clinical data of 40 patients receiving robotic assisted thoracoscopic anatomic lung resection from March to June 2016 in our department were reviewed. There were 29 males and 11 females with the age of 54-78 (60.2±12.7) years in the RATS group, and 27 males and 10 females with the age of 52-76 (58.7±11.5) years in the VATS group. Lung space-occupying lesions were comfirmed by preoperative diagnosis. The operative time, blood loss, chest tube retention time, postoperative hospital stay and perioperative morbidity and mortality were analyzed. The safety and feasibility were evaluated, and the learning curve was summed up.ResultsOperative time, postoperative ventilation time, intraoperative blood loss, chest tube retention time, postoperative pain, average hospital stay, postoperative complication rate between two groups were not statistically significant. In the RATS group preoperative preparation time was longer than that of the VATS group (24.5 min vs. 15.6 min, P=0.003), and the rate of conversion to thoracotomy of the RATS group was lower than that of the VATS group (0 vs. 10.8%). There was no perioperative death in two groups.ConclusionRobotic-assisted thoracic surgery is safe and effective in the early learning process, and the learning curve can be entered into the standard stage from the learning stage after initial 10 operations.
ObjectiveThrough the perioperative outcome analysis of da Vinci robot-assisted sleeve lobectomy, to clarify its efficacy and safety.MethodsA retrospective analysis was performed on 10 patients with centrally located lung cancer undergoing robot-assisted sleeve lobectomy from March to December 2019 in our center, including 9 males and 1 female, aged 45-67 (55.0±8.9) years. Preoperative imaging and bronchoscopy showed central non-small cell lung cancer, involving the right upper lung in 3 patients, right lower lung in 2 patients, the left upper lung in 4 patients, and left lower lung in 1 patient. The operation time, Docking time, intraoperative blood loss volume, bronchial anastomosis time, number of dissected lymph nodes, drainage volume and postoperative hospital stay were analyzed.ResultsThe da Vinci robot-assisted bronchial sleeve lobectomy was completed smoothly on 10 patients.

All patients had no bronchopleural fistula, pulmonary infection or atelectasis, and there was no perioperative death. Postoperative pathological findings were all squamous cell carcinoma.ConclusionDa Vinci robot-assisted sleeve lobectomy is safe and effective.
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 explore the application value of prognostic nutritional index (PNI) in the postoperative complications of McKeown surgery for da Vinci robotic esophageal cancer. MethodsThe clinical data of the patients who underwent da Vinci robotic McKeown surgery for esophageal cancer in the Department of Thoracic Surgery of the First Hospital of Lanzhou University from January 2019 to June 2022 were retrospectively collected. According to the receiver operating characteristic (ROC) curve, the optimal cut-off value of PNI for predicting postoperative complications was explored. The patients were divided into a high PNI group and a low PNI group according to the cut-off value, and the differences in basic characteristics, surgery-related indexes and postoperative complications between the two groups were analyzed. According to the occurrence of postoperative complications, the patients were divided into a non-complication group and a complication group. Univariate and multivariate analyses were used to explore the influence of relevant indicators on the occurrence of postoperative complications in da Vinci robotic McKeown surgery for esophageal cancer. ResultsFinally 120 patients were collected, including 95 males and 25 females, with an average age of 62.82 years. The preoperative hemoglobin content, preoperative blood lymphocyte count, preoperative serum albumin and preoperative blood total cholesterol in the high PNI group were higher than those in the low PNI group (P<0.05). There were statistical differences between the two groups in the incidences of postoperative overall complications, pulmonary infection, pleural effusion and poor incision healing (P<0.05). The relevant indicators that may cause postoperative complications were included in univariate analysis, and the results showed that age, operation time, intraoperative blood loss, preoperative blood lymphocyte count, preoperative hemoglobin content, preoperative blood mononuclear cell count, preoperative blood monocyte count, serum albumin level and PNI were possible influencing factors of postoperative complications after da Vinci robotic McKeown surgery for esophageal cancer. Incorporating these influencing factors into multivariate analysis, the results showed that age, PNI, operation time and intraoperative blood loss were independent influencing factors of postoperative complications. ConclusionPNI has certain predictive value in the postoperative complications of da Vinci robotic McKeown surgery for esophageal cancer. PNI is an independent factor affecting postoperative complications. Improving the level of PNI in esophageal cancer patient before surgery may help reduce the occurrence of postoperative complications.
Objective To investigate the application of enhanced recovery after surgery (ERAS) in da Vinci robotic McKeown surgery for esophageal cancer. Methods Clinical data of patients admitted to the First Hospital of Lanzhou University and undergoing da Vinci robotic McKeown surgery for esophageal cancer from 2017 to 2021 were retrospectively analyzed. According to the treatment, they were divided into two groups, a conventional group and an ERAS group. Patients in the conventional group were treated with the conventional perioperative treatment mode of thoracic surgery, and patients in the ERAS group were treated with accelerated rehabilitation surgical treatment mode. Relevant hospitalization indicators and postoperative complication rates were compared between the two groups. Results Finally 128 patients were collected, including 106 males and 22 females, with an average age of 61.91 years. There were 71 patients in the conventional group and 57 patients in the ERAS group. The postoperative pain index in the ERAS group was significantly lower than that in the conventional group (P<0.05), and the duration of postoperative analgesic pump used in the ERAS group was shorter than that in the conventional group (2.39±0.49 d vs. 3.13±0.63 d, P<0.001). There was no statistical difference in the incidence of postoperative related complications (gastroesophageal reflux, anastomotic stenosis, anastomotic fistula, arrhythmia, recurrent laryngeal nerve injury, chylothorax, anastomosis stomatitis or incisional infection) between the two groups (P>0.05), but the incidence of postoperative lung infection in the ERAS group was statistically lower (12.28% vs. 26.76%, P=0.043), and the volume of postoperative pleural effusion was statistically less compared with the conventional group (P<0.05). In the ERAS group, the surgery time (294.35±15.19 min vs. 322.79±59.09 min, P<0.001), postoperative exhaust time (1.44±0.39 d vs. 1.94±0.43 d, P<0.001), postoperative removal time of nasolasal tube (6.79±0.73 d vs. 8.21±0.86 d, P<0.001), hospital stay (19.88±3.36 d vs. 21.34±3.59 d, P=0.020), hospitalization costs (105 575.28±8 960.75 yuan vs. 137 894.64±19 518.60 yuan, P<0.001) were all lower or shorter than those of the conventional group. Postoperative activity was longer in the ERAS group than that in the conventional group (P<0.05), but there was no statistical difference in preoperative anesthesia time between the two groups (P=0.841). Conclusion The application of ERAS in da Vinci robotic McKeown surgery for esophageal cancer can effectively alleviate the physiological and psychological burden of patients, reduce the occurrence of postoperative related complications, effectively shorten the total hospital stay, save hospitalization costs, and reduce the economic burden of patients and society. Therefore, it can be promoted and applied in the clinic.
Objective To analyze the feasibility of totally no tube (TNT) in da Vinci robotic mediastinal mass surgery and its significance for fast track surgery. Methods A total of 79 patients receiving robotic mediastinal TNT surgery in the General Hospital of Shenyang Military Command from January 2016 to December 2017 were enrolled as a TNT group; 35 patients receiving robotic mediastinal surgery in General Hospital of Shenyang Military Command from January 2014 to December 2017 and 54 patients receiving thoracoscopic mediastinal surgery during the same period were enrolled as a non-TNT group and a video-assisted thoracoscopic surgery (VATS) group. The muscle relaxation and tracheal intubation/laryngeal masking time, operation time, intraoperative blood loss, postoperative ICU stay, postoperative hospital stay, postoperative visual analogue scale (VAS), hospitalization costs and postoperative complications and other related indicators were retrospectively analyzed among the three groups. Results Surgeries were successfully completed in 168 patients with no transfer to thoracotomy, serious complications (postoperative complications in 9 patients) or death during the perioperative period. All patients were discharged. Compared with the non-TNT group, the TNT group had significantly less muscle relaxation-tracheal intubation/laryngeal masking time, operation time, intraoperative blood loss, VAS pain score, ICU stay, postoperative hospital stay (P<0.01); there was no significant difference in the total cost of hospitalization between the two groups (P>0.05). Between the non-TNT group and the VATS group, there was no significant difference in time of muscle relaxation and tracheal intubation, operation time and ICU stay (P>0.05). The non-TNT group was superior to the VATS group in terms of intraoperative blood loss, VAS pain scores on the following day after operation, chest drainage volume 1-3 days postoperatively, postoperative catheterization time and postoperative hospital stay (P<0.05); but the cost of hospitalization in the non-TNT group was significantly higher (P=0.000). Conclusion The da Vinci robot is safe and feasible for the treatment of mediastinal masses. At the same time, TNT is also safe and reliable on the basis of robotic surgery which has many advantages such as better comfort, less pain, ICU stay and hospital stay as well as faster recovery.

MethodsFrom January 2009 to October 2010, 180 patients with hepatopancreaticobiliary and gastrointestinal disease underwent robotic surgeries by using da Vinci surgical system, including 58 patients with biliary malignant tumor. The case distribution, intra and postoperative data were analyzed. ResultsOf 58 patients, 3 patients with intrahepatic bile duct cystadenocarcinoma received wedge resections of liver. In 36 patients with hilar cholangiocarcinoma, anatomical left hemihepatectomies were performed in 3 cases, resection of extrahepatic duct and gallbladder bridge type biliary revascularization in 3 cases, resection of extrahepatic duct and biliary-enteric Roux-en-Y anastomosis in 14 cases, tumor resection and revascularization of hepatic portal bile duct in 1 case, palliative external drainage of intrahepatic bile duct in 5 cases, and Y-internal drainage of hepatic portal in 10 cases. In 10 patients with gallbladder carcinoma, resection of extrahepatic duct and gallbladder and biliaryenteric Roux-en-Y anastomosis in 2 cases, cholecystectmy in 3 cases, cholecystectmy and external drainage of intrahepatic bile duct in 1 case, cholecystectmy and Y-internal drainage by suspension of hepatic portal in 4 cases. A patient with middle bile duct cancer received radical resection of cholangiocarcinoma and biliary-enteric Roux-en-Y anastomosis. Of 8 patients with distal bile duct cancer, Whipple procedure were performed. Of 58 patients, 2 cases converted to hand-assistant procedure (3.4%). For all patients, operation time was (6.18±1.71) h, blood loss was (116.66±56.06) ml, blood transfusion was (85.55±38.28) ml, ambulation time was (9.10±2.91) h, feeding time was (14.95±4.35) h, and hospital stay was (12.81±4.29) d. Postoperative complications occurred in 8 cases (13.8%), including bile leakage (3 cases), wound bleeding (1 case), pancreatoenteric anastomotic leakage (2 cases), pulmonary infection (1 case), and renal failure (1 case). Of these 8 cases, 6 cases recovered smoothly and 2 cases die of severe pulmonary infection and renal failure after conservative treatment (3 or 4 weeks), therefore, the mortality of patients was 3.4%. In 36 patients with hilar cholangiocarcinoma, 19 cases died (on 2 monthes 4 cases, on 6 monthes 5 cases, on 10 monthes 8 cases, and on 12 monthes 2 cases after operation), 11 cases survival well (gt;26 monthes 4 cases, gt;22 monthes 3 cases, and gt;19 monthes 4 cases), and 6 cases required hospitalization. Of 10 patients with gallbladder carcinoma, 7 cases died (on 3 monthes 1 case, on 5 monthes 1 case, on 8 monthes 1 case, on 11 monthes 3 cases, and on 12 monthes 1 case after operation) and 3 cases survival (gt;17 monthes 2 cases, gt;13 monthes 1 case). In 8 cases undergoing pancreatoduodenectomy, 5 cases died (on 4 monthes 2 cases, on 6 monthes 2 cases, and 10 monthes 1 case after operation) and 3 cases survived well over 2 years. Three patients with intrahepatic bile duct cystadenocarcinoma survived over 1 year. Conclusionsda Vinci surgical system can carry out all kinds of surgery for biliary malignant tumor, especially prominent in the complicated surgeries for hepatic portal, which breaks through the restricted area of laparoscope in hepatobiliary malignant tumor.
ObjectiveTo understand the present situation and effect of da Vinci robot in the treatment of obesity.MethodThe literatures about the application of da Vinci surgical robot in metabolic surgery for weight loss were reviewed.Resultsda Vinci surgical robot was a minimally invasive surgical system in recent years. Because of its unique structure, it broke through the limitations of traditional laparoscopic surgery, such as lack of field of vision, two-dimensional imaging, unstable lens, limited range of movement, and so on.
