  • The learning curve for da Vinci robot-assisted mediastinal tumor resection by using cumulative sum analysis

    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.

  • Retrospective analysis of mediastinal mass resection with totally no tube during da Vinci robotic surgery for 79 patients

    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.

  • Robotic lung resection for malignant and benign lesions: experience with 1 000 patients

    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.

  • Influencing factors analysis of thoracic drainage time after da Vinci robot lung cancer surgery and preventive solution

    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.
