ObjectiveTo investigate the clinical effect of three-port Da Vinci robot-assisted radical resection of lung cancer. MethodsThe clinical data of patients who underwent Da Vinci robot-assisted radical resection of lung cancer in the Second Department of Thoracic Surgery, the First Affiliated Hospital of Xiamen University from April 2021 to March 2022 were retrospectively analyzed. According to the number of surgical ports, they were divided into two groups: a three-port group (three-port Da Vinci robot-assisted radical resection of lung cancer), and a four-port group (traditional Da Vinci robot-assisted radical resection of lung cancer). The operation time, intraoperative bleeding, lymphadenectomy, total thoracic drainage, extubation time, postoperative complications and postoperative pain of the two groups were compared and analyzed. ResultsA total of 58 patients were included, including 19 males and 39 females, aged 31-79 years. There were 21 patients in the three-port group, and 37 patients in the four-port group. The visual analogue scores on the first and third day after the operation were 4.33±1.20 points and 2.24±0.77 points in the three-port group, and 5.11±1.22 points and 2.78±1.06 points in the four-port group, and there were statistical differences between the two groups (P<0.05). There was no significant difference between the two groups in terms of operation time, intraoperative bleeding, lymph node dissection, postoperative thoracic drainage, time of thoracic tube insertion or postoperative complications (P>0.05). ConclusionThree-port Da Vinci robot-assisted radical resection of lung cancer can reduce the postoperative pain without increasing the operation difficulty and complications, and can be widely used in the clinical practice.
ObjectiveTo compare the surgical efficacy of Da Vinci robot-assisted minimally invasive esophagectomy (RAMIE) and video-assisted minimally invasive esophagectomy (VAMIE) on esophageal cancer.MethodsOnline databases including PubMed, the Cochrane Library, Medline, EMbase and CNKI from inception to 31, December 2019 were searched by two researchers independently to collect the literature comparing the clinical efficacy of RAMIE and VAMIE on esophageal cancer. Newcastle-Ottawa Scale was used to assess quality of the literature. The meta-analysis was performed by RevMan 5.3.ResultsA total of 14 studies with 1 160 patients were enrolled in the final study, and 12 studies were of high quality. RAMIE did not significantly prolong total operative time (P=0.20). No statistical difference was observed in the thoracic surgical time through the McKeown surgical approach (MD=3.35, 95%CI –3.93 to 10.62, P=0.37) or in surgical blood loss between RAMIE and VAMIE (MD=–9.48, 95%CI –27.91 to 8.95, P=0.31). While the RAMIE could dissect more lymph nodes in total and more lymph nodes along the left recurrent laryngeal recurrent nerve (MD=2.24, 95%CI 1.09 to 3.39, P=0.000 1; MD=0.89, 95%CI 0.13 to 1.65, P=0.02) and had a lower incidence of vocal cord paralysis (RR=0.70, 95%CI 0.53 to 0.92, P=0.009).ConclusionThere is no statistical difference observed between RAMIE and VAMIE in surgical time and blood loss. RAMIE can harvest more lymph nodes than VAMIE, especially left laryngeal nerve lymph nodes. RAMIE shows a better performance in reducing the left laryngeal nerve injury and a lower rate of vocal cord paralysis compared with VAMIE.
ObjectiveTo compare the perioperative outcomes between robot-assisted complex segmentectomy and simple segmentectomy for stage ⅠA non-small cell lung cancer (NSCLC). MethodsThe clinical data of 285 patients with NSCLC undergoing robot-assisted thoracic surgery (RATS) in our hospital from January 2015 to August 2021 were retrospectively analyzed. There were 105 males and 180 females aged 23-83 years. The patients were divided into a complex segmentectomy group (n=170) and a simple segmentectomy group (n=115) according to tumor location and surgical method. The clinical pathological baseline characteristics and perioperative outcomes between the two groups were compared, including operative time, blood loss volume, dissected lymph nodes, conversion rate, postoperative duration of drainage, postoperative hospital stay, the incidence of persistent air leakage and postoperative 30 d mortality. ResultsThere was no statistical difference in baseline data between the two groups (P>0.05). No postoperative 30 d death was observed. One patient in the complex segmentectomy group was transferred to thoracotomy. No statistical difference was observed between the two groups in the operative time (97.36±38.16 min vs. 94.65±31.67 min, P=0.515), postoperative duration of drainage (3.69±1.85 d vs. 3.60±1.90 d, P=0.679), postoperative hospital stay (4.07±1.85 d vs. 4.05±1.97 d, P=0.957), dissected lymph nodes (5.15±3.53 vs. 5.13±2.93, P=0.952), incidence of blood loss volume<100 mL (98.2% vs. 99.1%, P=0.650), and incidence of postoperative persistent air leakage (6.5% vs. 5.2%, P=0.661). ConclusionThe safety and effectiveness of robot-assisted complex segmentectomy and simple segmentectomy are satisfactory in the treatment of stage ⅠA NSCLC. The perioperative results of RATS complex segmentectomy and simple segmentectomy are similar.
ObjectiveTo summarize the efficacy of robot-assisted thoracic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) in the treatment of left upper lobectomy for non-small cell lung cancer. MethodsThe clinical data of patients with non-small cell lung cancer who underwent left upper lobectomy with RATS or VATS in our center from January 2019 to October 2021 were retrospectively analyzed. The patients were divided into two groups according to surgical methods: a RATS group and a VATS group. The baseline clinical data and results were compared between the two groups. ResultsA total of 145 patients were included. There were 78 males and 67 females with a mean age of 59.9 years. There were 63 patients in the RATS group and 82 patients in the VATS group. There was no death within 30 days after operation in both groups. In the RATS group, the drainage volume on the second postoperative day (233.49±83.94 mL vs. 284.88±120.21 mL, P=0.003), total operative time (126.94±29.50 min vs. 181.59±61.51 min, P=0.000), intraoperative resection time of the left upper lobe (76.48±27.52 min vs. 107.23±47.84 min, P=0.000), intraoperative blood loss (P=0.000), and conversion rate to thoracotomy (P=0.018) were significantly better than those in the VATS group. The group (5.41±0.94 groups vs. 4.83±1.31 groups, P=0.002) and number (18.27±7.39 vs. 12.76±6.54, P=0.000) of dissected lymph nodes in the RATS group were significantly more than those in the VATS group. The differences in the drainage volume on the first day after operation, postoperative intubation time, postoperative hospital stay or postoperative complications between the two groups were not statistically significant (P>0.05). ConclusionThe application of RATS in the left upper lobectomy for non-small cell lung cancer is safe and feasible, and has obvious advantages over VATS.
ObjectiveTo compare short- and medium-term effects of Leonardo da Vinci robot-assisted and traditional mitral valvuloplasty.MethodsWe conducted a retrospective analysis of 74 patients who underwent mitral valvuloplasty in our hospital from January 2015 to March 2017. The patients were divided into two groups according to the mode of operation: a da Vinci group (n=29, 13 males, 16 females at an average age of 52 years) and a routine group (n=45, 18 males, 27 females at an average age of 53 years). The perioperative data of patients in the two groups were compared and analyzed.ResultsThere was no significant difference in sex, age, weight, height, body mass index (BMI), cardiac function (NYHA), hypertension, diabetes, postoperative blood transfusion and postoperative complications between the two groups (P>0.05). The tracheal intubation time, ICU retention time, hospital stay time, blood loss and postoperative drainage in the da Vinci group were shorter or less than those in the routine group (P<0.05). The operation time, cardiopulmonary bypass time and aortic clamping time in the da Vinci group were longer than those in the routine group (P<0.05). Different surgical procedures had no significant effect on left atrial diameter (LAD), left ventricular end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF) and mitral regurgitation (MR) 3 years after operation. There was no interaction between the mode of operation and the time of follow-up. There was no significant difference in echocardiographic evaluation in the same period (P>0.05).ConclusionDa Vinci operation shortens the rehabilitation process of patients compared with traditional surgery. For short- and medium-term follow-up results, there is no difference between Leonardo da Vinci and traditional mitral valve surgeries, and the clinical effect of da Vinci robot-assisted mitral valvuloplasty is satisfactory, which is worthy of further clinical promotion.
ObjectiveTo explore the clinical efficacy of robot-assisted coronary artery bypass grafting through a small incision in the left intercostal space in the treatment of multivessel coronary disease. MethodsA retrospective analysis was conducted on the clinical data of patients who underwent coronary artery bypass grafting through a small incision in the left intercostal space at Central China Fuwai Hospital of Zhengzhou University from January 1, 2023 to October 15, 2024. Patients were divided into a robotic group and a minimally invasive group based on whether the surgery was assisted by the Da Vinci robot. ResultsA total of 81 patients were included, with 57 in the minimally invasive group, including 41 males and 16 females, with a median age of 65.0 (57.5, 69.5) years; and 24 in the robotic group, including 17 males and 7 females, with a median age of 61.0 (56.0, 69.0) years. There was no statistically significant difference in baseline data between the two groups (P>0.05). The robotic group had less intraoperative bleeding [300 (200, 438) mL vs. 500 (375, 600) mL, P=0.006], shorter postoperative mechanical ventilation time [15.0 (13.3, 23.5) h vs. 22.0 (15.5, 39.5) h, P=0.037], and lower incidence of postoperative pain [8 (33.3%) vs. 33 (57.9%), P=0.043]. The hospitalization cost in the robotic group was higher than that in the minimally invasive group [130491 (123298, 135691) yuan vs. 123892 (115543, 133449) yuan, P=0.023]. There was no statistical difference in postoperative laboratory indicators between the two groups (P>0.05). There was also no statistical difference in the duration of surgery, postoperative 24 h drainage volume, ICU stay time, postoperative hospital stay or incidences of perioperative compications including pleural effusion, transfusion, new-onset atrial fibrillation, acute kidney injury, non-union of incision, major cardiovascular and cerebrovascular adverse events, and reoperation between the two groups (P>0.05). ConclusionCompared with the minimally invasive group, the robotic group shows satisfactory efficacy and can effectively reduce postoperative pain and intraoperative bleeding, and shorten postoperative mechanical ventilation time.
ObjectiveTo compare the differences in the learning curve and surgeon's perception for pulmonary lobectomy performed by a single surgeon using the da Vinci surgical robot versus a domestically-made robotic system. Methods A retrospective analysis was conducted on the clinical data of the first 70 consecutive patients who underwent lobectomy with the da Vinci robot and the first 70 with a domestic robot. All procedures were performed by a single thoracic surgeon at Gansu Provincial Hospital who initiated the use of both systems concurrently between 2021 and 2024. Data were analyzed using SPSS 26.0, and learning curves for both groups were plotted and analyzed using the cumulative sum (CUSUM) method. Results The da Vinci group included 41 males and 29 females with a mean age of (66.0±6.83) years and the domestic robot group included 42 males and 28 females;with a mean age of (65.09±6.14) years. For the da Vinci group, the mean operative time was (196.14±29.63) min. The CUSUM learning curve was best fitted by a cubic equation (R2=0.986; CUSUM=0.012X3−1.799X2+69.149X−59.239, where X was the surgical volume), which peaked at the 26th case, delineating the learning and mastery phases. Statistically significant differences were observed between these phases in operation time, setup time, console time, intraoperative blood loss, postoperative day 1 drainage, and number of lymph nodes dissected (all P<0.01). For the domestic robot group, the mean operative time was (187.57±24.62) min. Its CUSUM learning curve also followed a cubic fit (R2=0.910; CUSUM=0.008X3−1.152X2+40.465X+91.940), peaking at the 18th case. Significant improvements between the learning and mastery phases were also found for the same surgical metrics (all P<0.05). The surgeon's perception score was significantly higher for the da Vinci system compared to the domestic system (4.21±0.88 vs. 3.29±1.02, P<0.05). ConclusionCUSUM analysis effectively distinguishes the learning and mastery phases for both systems. The learning curve for da Vinci robotic lobectomy is overcome after 26 cases, whereas the domestic robot required 18 cases. In the mastery phase, operative time, setup time, intraoperative blood loss, and postoperative day 1 drainage are significantly lower, while the number of lymph nodes dissected is significantly higher compared to the learning phase for both systems. There are no significant differences in short-term efficacy or safety between the two groups. However, the da Vinci system provids a superior surgeon experience.

Objective To analyze the risk factors for postoperative length of stay (PLOS) after mediastinal tumor resection by robot-assisted non-endotracheal intubation and to optimize the perioperative process. MethodsThe clinical data of patients who underwent Da Vinci robot-assisted mediastinal tumor resection with non-endotracheal intubation at the Department of Thoracic Surgery, General Hospital of Northern Theater Command from 2016 to 2019 were retrospectively analyzed. According to the median PLOS, the patients were divided into two groups. The univariate analysis and multivariate logistic regression were used to analyze risk factors for prolonged PLOS (longer than median PLOS). ResultsA total of 190 patients were enrolled, including 92 males and 98 females with a median age of 51.5 (41.0, 59.0) years. The median PLOS of all patients was 3.0 (2.0, 4.0) d. There were 71 patients in the PLOS>3 d group and 119 patients in the PLOS≤3 d group. Multivariate logistic regression showed that indwelled thoracic catheter [OR=11.852, 95%CI (2.384, 58.912), P=0.003], preoperative symptoms of muscle weakness [OR=4.814, 95%CI (1.337, 17.337), P=0.016] and postoperative visual analogue scale>5 points [OR=6.696, 95%CI (3.033, 14.783), P<0.001] were independent factors for prolonged PLOS. Totally no tube (TNT) allowed patients to be discharged on the first day after surgery. ConclusionRobot-assisted mediastinal tumor resection with non-endotracheal intubation can promote rapid recovery. The methods of optimizing perioperative process are TNT, controlling muscle weakness symptoms and postoperative pain relief.
ObjectiveTo estimate postoperative pain and use of analgesic of patients who underwent video-assisted thoracoscopic surgery(VATS) or robotic assisted thoracoscopic surgery(RATS). MethodsFrom October 2014 through August 2015, 339 patients were treated by surgery in Shanghai Chest Hospital. Among them, 116 patients with intrathoracic lesions who underwent RATS with the da Vinci? Surgical System were as a RATS group with 51 males and 65 females at age of 52.59±11.49 years. Another 223 patients by VATS were as a VATS group with 93 males and 130 females at age of 58.00±10.56 years. We recorded the data of the VAS score and use analgesic of the patients after surgery. ResultsThere was a significant difference in VAS score between the RATS group and the VATS group(3.01±0.18 vs. 5.19±0.14, P<0.05). Astatistical difference of analgesic use between RATS and VATS was also found(1.09±0.12 vs. 1.77±0.10, P<0.05). ConclusionCompared with VATS, the postoperative pain of the patients who underwent RATS is lighter. And the use of analgesic is less.
