ObjectiveTo summarize the advantages and disadvantages of different surgical approaches in thyroidectomy using the da Vinci robotic surgical system. MethodThe relevant to articles about da Vinci robotic thyroidectomy via different surgical approaches at home and abroad were retrieved and reviewed. ResultsThe robot-assisted transaxillary thyroidectomy had a definite curative effect and was a mature technology. The bilateral axillary-breast approach thyroidectomy had a wide range of applications and was suitable for beginners. The robotic retroauricular approach thyroidectomy had great advantages in the dissection of lateral cervical lymph nodes. The transoral robotic thyroidectomy was a surgical approach that conformed to the minimally invasive concept. Conclusions Da Vinci robotic thyroidectomy via different surgical approaches has its corresponding application scope and advantages. Clinical surgeons should choose an optimal surgical approach according to the tumor location, size and number of patients and the advantages of the operator, so as to achieve the therapeutic effect of radical cure of tumors and reduction of injury.
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.
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.
ObjectiveThe aim of this study was to evaluate the safety and feasibility of robot-assisted surgery in pancreatic cancer.MethodRecent literatures related to robot-assisted surgery in treatment of pancreatic cancer compared with traditional open surgery or traditional laparoscopic surgery were collected to make an review.ResultsCompared with the traditional laparoscopic surgery, the robot-assisted surgery was expensive, with the obvious advantages in terms of anastomosis and reconstruction. Compared with the open operation, both robot-assisted pancreaticoduodenectomy and robot-assisted distal pancreatectomy had longer operation time, but the length of hospital stay and intraoperative blood loss were obviously shortened, robot-assisted distal pancreatectomy also had higher spleen preservation rate. Compared with the traditional laparoscopic distal pancreatectomy, the number of lymph node retrieved, R0 resection rate, and splenic preservation rate were also higher in the robot-assisted group. Simultaneously, robot-assisted total pancreatectomy and midsection pancreatectomy were deemed as safe in some high-volume centers.ConclusionsRobot-assisted pancreatic cancer surgery is safe and feasible, but many surgeries are restricted to a small number of high-volume medical centers, and most cases selected to undergo robot-assisted surgery are often early stage patients with small tumor size. A lot of efforts should be made and problems should be solved.
ObjectiveTo investigate the effects of robotic versus thoracoscopic lobectomy on body trauma and lymphocyte subsets in patients with non-small cell lung cancer (NSCLC).MethodsThe clinical data of 120 patients with NSCLC who underwent lobectomy in the same operation group at the same period were collected and divided into a robot group (n=60) and a thoracoscope group (n=60) according to different surgical methods. The operation time, intraoperative blood loss, postoperative drainage time, drainage volume, postoperative hospital stay, complication rate, pain visual analogue scale (VAS) and other perioperative indicators were recorded in the two groups. Inflammatory markers: C-reactive protein (CRP), interleukin-6 (IL-6) and lymphocyte subsets (CD3+, CD4+, CD8+, CD4+/CD8+) levels were measured before and 1 d, 3 d after surgery. The effects of the two surgical methods on the body trauma and lymphocyte subsets were compared.ResultsThe operation time, intraoperative blood loss, postoperative drainage time, drainage volume and VAS of the robot group were lower than those of the thoracoscope group, and the differences were statistically significant (P<0.05). On the 1st day after surgery, IL-6 of the thoracoscope group was higher than that of the robot group, while CD3+, CD4+ and CD8+ were lower than those of the robot group, with statistically significant differences (P<0.05).ConclusionCompared with thoracoscopic lobectomy, robotic lobectomy has less trauma, less inflammatory response, faster recovery, less inhibitory effect on lymphocyte subsets, and has clinical advantages.
Objective To investigate the feasibility and effectiveness of robot-assisted posterior minimally invasive access in treatment of thoracolumbar tuberculosis via transforaminal expansion approach. Methods A clinical data of 40 patients with thoracolumbar tuberculosis admitted between January 2017 and May 2022 and met the selection criteria was retrospectively analyzed. Among them, 15 cases were treated with robot-assisted and minimally invasive access via transforaminal expansion approach for lesion removal, bone graft, and internal fixation (robotic group), and 25 cases were treated with traditional transforaminal posterior approach for lesion removal and intervertebral bone grafting (traditional group). There was no significant difference in the baseline data between the two groups (P>0.05) in terms of gender, age, lesion segment, and preoperative American Spinal Injury Association (ASIA) grading, Cobb angle, visual analogue scale (VAS) score, erythrocyte sedimentation rate (ESR), and C reactive protein (CRP). The outcome indicators were recorded and compared between the two groups, including operation time, intraoperative bleeding volume, hospital stay, postoperative bedtime, complications, ESR and CRP before operation and at 1 week after operation, the level of serum albumin at 3 days after operation, VAS score and ASIA grading of neurological function before operation and at 6 months after operation, the implant fusion, fusion time, Cobb angle of the lesion, and the loss of Cobb angle observed by X-ray films and CT. The differences of ESR, CRP, and VAS score (change values) between pre- and post-operation were calculated and compared. Results Compared with the traditional group, the operation time and intraoperative bleeding volume in the robotic group were significantly lower and the serum albumin level at 3 days after operation was significantly higher (P<0.05); the postoperative bedtime and the length of hospital stay were also shorter, but the difference was not significant (P>0.05). There were 2 cases of poor incision healing in the traditional group, but no complication occurred in the robotic group, and the difference in the incidence of complication between the two groups was not significant (P>0.05). There were significant differences in the change values of ESR and CRP between the two groups (P<0.05). All Patients were followed up, and the follow-up time was 12-18 months (mean, 13.0 months) in the traditional group and 12-16 months (mean, 13.0 months) in the robotic group. Imaging review showed that all bone grafts fused, and the difference in fusion time between the two groups was not significant (P>0.05). The difference in Cobb angle between the pre- and post-operation in the two groups was significant (P<0.05); and the Cobb angle loss was significant more in the traditional group than in the robotic group (P<0.05). The VAS scores of the two groups significantly decreased at 6 months after operation when compared with those before operation (P<0.05); the difference in the change values of VAS scores between the two groups was not significant (P>0.05). There was no occurrence or aggravation of spinal cord neurological impairment in the two groups after operation. There was a significant difference in ASIA grading between the two groups at 6 months after operation compared to that before operation (P<0.05), while there was no significant difference between the two groups (P>0.05). Conclusion Compared with traditional posterior open operation, the use of robot-assisted minimally invasive access via transforaminal approach for lesion removal and bone grafting internal fixation in the treatment of thoracolumbar tuberculosis can reduce the operation time and intraoperative bleeding, minimizes surgical trauma, and obtain definite effectiveness.

Objective To explore the effectiveness of reduction robot combined with navigation robot-assisted minimally invasive treatment for Tile type B pelvic fractures. Methods Between January 2022 and February 2023, 10 patients with Tile type B pelvic fractures were admitted. There were 6 males and 4 females with an average age of 45.5 years (range, 30-71 years). The fractures were caused by traffic accident in 5 cases, bruising by heavy object in 3 cases, and falling from height in 2 cases. The interval between injury and operation ranged from 4-13 days (mean, 6.8 days). There were 2 cases of Tile type B1 fractures, 1 case of Tile type B2 fracture, and 7 cases of Tile type B3 fractures. After closed reduction under assistance of reduction robot, the anterior ring was fixed with percutaneous screws with or without internal fixator, and the posterior ring was fixed with sacroiliac joint screws under assistance of navigation robot. The time of fracture reduction assisted by the reduction robot was recorded and the quality of fracture reduction was evaluated according to the Matta scoring criteria. The operation time, intraoperative fluoroscopy frequency and time, intraoperative bleeding volume, and incidence of complications were also recorded. During follow-up, the X-ray film of pelvis was taken to review the fracture healing, and the Majeed score was used to evaluate hip joint function. Results The time of fracture reduction was 42-62 minutes (mean, 52.3 minutes). The quality of fracture reduction according to the Matta scoring criteria was rated as excellent in 4 cases, good in 5 cases, and poor in 1 case, with excellent and good rate of 90%. The operation time was 180-235 minutes (mean, 215.5 minutes). Intraoperative fluoroscopy was performed 18-66 times (mean, 31.8 times). Intraoperative fluoroscopy time was 16-59 seconds (mean, 28.6 seconds). The intraoperative bleeding volume was 50-200 mL (range, 110.0 mL). No significant vascular or nerve injury occurred during operation. All patients were followed up 13-18 months (mean, 16 months). X-ray films showed that all fractures healed with the healing time of 11-14 weeks (mean, 12.3 weeks). One case of ectopic ossification occurred during follow-up. At last follow-up, the Majeed score was 70-92 (mean, 72.7), and the hip joint function was rated as excellent in 2 cases and good in 8 cases, with the excellent and good rate of 100%. Conclusion The reduction robot combined with navigation robot-assisted minimally invasive treatment for Tile type B pelvic fractures has the characteristics of intelligence, high safety, convenient operation, and minimally invasive treatment, which can achieve reliable effectiveness.
Robotic gastric cancer surgery had developed rapidly in recent years, and its clinical application had come a long way. More and more studies had demonstrated that the robotic gastric cancer surgery was a safe and feasible procedure, and showed the technical advantages in the lymph node dissection, bleeding control, precise surgery, and postoperative recovery over laparoscopic surgery. However, some limitations such as the high surgical costs, lack of high-quality evidence, insufficient intelligence limited the development of robotic gastric cancer surgery. In the future, with more high-quality evidence-based medicine research and the development of intelligent surgical robots, the robotic gastric cancer surgery will be further standardized and promoted. We believe that robotic gastric cancer surgery will become the mainstream of minimally invasive surgery for the treatment of gastric cancer.
