ObjectiveTo explore the efficacy of da Vinci robotic surgical system-assisted radical resection of rectal cancer. MethodsThe clinical data of 456 patients who received radical resection of rectal cancer by the da Vinci robotic surgical system at the Southwest Hospital from March 2010 to March 2016 were retrospectively analyzed. Operative time, operative blood loss, number of harvested lymph nodes, hospital stay, and morbidity were evaluated. Resultsda Vinci robotic surgical system-assisted radical resection of rectal cancer were successfully carried out in 445 patients, and other 11 patients were converted to open surgery (2.4%). Of 456 patients, 322 patients underwent anterior resection of rectum procedure (70.6%), 126 patients underwent abdominoperineal excision procedure (27.6%), 8 patients underwent Hartmann procedure (1.8%). The mean operative time was (192±60) min, the mean operative blood loss was (110±93) mL, the mean number of harvested lymph nodes were 19±6, the mean length between distal resection margin and tumor were (3.5±1.8) cm, the mean time for patients taking normal activity was (2.9±1.5) d, the mean time of passage of the first flatus was (2.7±1.7) d, the mean hospital stay was (7.1±1.6) d. Surgical complications occurred in 40 patients (8.8%), and all the patients were recovery before leaving hospital. The mean follow-up time was 29.1-month (3-75 months). There were 70 patients suffered from occurrence or metastasis (16.2%), and 60 patients died (13.9%). Conclusionda Vinci robotic surgical system-assisted radical resection for rectal cancer is a feasible and safe surgical procedure with the minimal trauma, fast recovery, and satisfactory clinical efficacy.
Objective To investigate the learning curve for da Vinci robot-assisted mediastinal tumor resection (DRMTR). Methods A total of 50 consecutive patients received DRMTR between March 2011 and September 2012 in our hospital. Clinical data of the 50 patients were collected and analyzed. There were 23 males, 27 females aged 46.9(17–80) years. The learning curve was evaluated by using the cumulative sum (CUSUM) analysis. Results The mean operation time was 124.6 min. The CUSUM learning curve was best modeled as a third-order polynomial curve with the equation: CUSUM=0.046×case-number3–4.681×case-number2+127.508×case-number–237.940, which had a highR2 value of 0.868. The fitting curve reached the top after the 19th case, which suggested that the surgeons master the technique after they finished 19 cases. As a cut-off point, the 19th case divided the learning curve into two phases, in which there was statistical diffference in operation time (P<0.01), intraoperative blood loss (P<0.01), the postoperative duration of chest tube drainage (P<0.01 ) and the rate of postoperative complications (P<0.05 ). Conclusion The DRMTR identified by CUSUM analysis represents two characteristic stages of DRMTR: the learning stage and the mastery stage. It is suggested from our data that the surgeons need finish about 19 cases to master DRMTR.
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 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.
ObjectiveTo analyze the perioperative outcome of consecutive 1 000 patients undergoing robotic lung resection and summarize surgical experience.MethodsWe retrospectively reviewed the clinical data of 1 000 patients undergoing robotic lung resection between May 2009 and June 2018 in Shanghai Lung Tumor Clinical Medical Center. Robotic lobectomy was compared with traditional VATS over the same period using a propensity-matched analysis. There were 327 males and 673 females at average age of 56.21±11.33 years. Lobectomy was performed in 866 patients (11 bilobectomy included), sublobar resection was performed in 129 patients, sleeve lobectomy was performed in the remaining 5 patients. Pathology was as follows: adenocarcinoma in 875 patients, squamous carcinoma in 52 patients, benign tumors in 73 patients. 90.5% of the primary lung cancer were in stage Ⅰ.ResultsThe mean operative time was 90.31±19.70 min; 95.70% of patients’ estimated blood loss was less than 100 ml. Conversion rate to thoracotomy was 0.90% (9 patients) . The average lymph node station and count harvested was 5.59±1.36 and 9.60±3.21 respectively. The mean volume of chest tube drainage on the first postoperative day was 229.19±131.67 ml. Median chest tube time was 3.85±1.43 d. There was 1 in-hospital death due to pulmonary embolism. A total of 189 patients had postoperative complications (18.90%) whose majority was postoperative air leak more than 5 days. The mean overall hospital costs was 92 710.53±12 367.23 Yuan. Compared with VATS, RATS was associated with significant reduction in intraoperative blood loss, time to chest tube removal and postoperative hospital stay. The operative time, conversion rate, lymph nodes removed, morbidity and mortality were similar between the two groups.ConclusionRobotic-assisted lung resection is safe and effective with low conversion rate and less complications, and it can overcome many disadvantages of traditional VATS.
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. The operation time was 135-183 (157.8±14.3) min, Docking time 6-15 (10.0±2.9) min, intraoperative blood loss volume 55-250 (124.5±61.8) mL, bronchial anastomosis time 17-40 (27.7±7.3) min, the number of dissected lymph nodes 16-23 (19.7±2.8), the drainage volume 200-600 (348.0±148.4) mL and postoperative hospital stay 7-11 (8.7±1.6) d. 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 compare the effect on postoperative immune function between da Vinci robot-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) , and to provide clinical support for more effective surgical procedures.MethodsA total of 90 patients undergoing radical resection of pulmonary carcinoma in our hospital from June to November 2019 were included. There were 49 males and 41 females with an average age of 62.67 (37-84) years. Among them, 50 patients underwent da Vinci robot-assisted thoracoscopic surgery (a RATS group) and 40 patients underwent video-assisted thoracoscopic surgery (a VATS group). The perioperative indexes as well as postoperative inflammatory factors and immune level effects between the two groups were compared.ResultsCompared with the VATS, RATS could significantly shorten the operation time and decrease intraoperative blood loss (P<0.05). RATS also effectively reduced the increase of postoperative inflammatory factor level (P<0.05). But there was no significant difference in postoperative immune function between the RATS group and the VATS group (P>0.05).ConclusionRATS is superior to VATS in the treatment of non-small cell lung cancer in perioperative indicators and inflammatory factors.
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 evaluate the feasibility and safety of da Vinci robotic surgery for elderly patients with radical surgery of lung cancer.MethodsWe retrospectively analyzed the clinical data of 59 patients aged over 70 years who underwent radical surgery of lung cancer in our hospital between 2016 and 2019. These patients were divided into two groups including a da Vinci robot group and a single-utility port video-assisted thoracoscopic surgery (VATS) group according to the patients’ selection of the treatments. There were 32 patients with 20 males and 12 females aged 73.1±2.3 years in the da Vinci robot group and 27 patients with 16 males and 11 females aged 71.2±1.3 years in the VATS group. The clinical data of the two groups were compared.ResultsThere was no statistical difference in surgery time between the two groups (t=–0.341, P=0.484). Compared with the VATS group, the da Vinci robot group had more number of lymph nodes dissected (t=1.635, P=0.015), less intraoperative blood loss (t=–2.569, P <0.001), less postoperative drainage amount within 3 days after surgery (t=–6.325, P=0.045), lower visual analogue scale (VAS) scores at postoperative 3rd day (t=–7.214, P=0.021).ConclusionThe da Vinci robot system is safe and efficient in the treatment for elderly patients with radical surgery of lung cancer with less trauma.
