  • Effectiveness analysis of 5G remote robotic surgery in pelvic fracture treatment

    Objective To investigate the effectiveness of 5G remote robotic surgery in the treatment of pelvic fractures. Methods A retrospective analysis was conducted on the clinical data of 160 patients with pelvic fractures admitted between July 2023 and June 2024 who met the selection criteria. Among these patients, 80 underwent internal fixation surgery with the assistance of 5G remote robotic surgery (5G group), while 80 received local robotic surgical assistance (control group). Baseline characteristics, including gender, age, body mass index, disease duration, cause of injury, and fracture classification, were compared between the two groups, and no significant difference was found (P>0.05). The incision length, operation time, intraoperative blood loss, hospital stay, accuracy of screw placement, maximum residual displacement postoperatively, quality of fracture reduction, incidence of complications, Majeed pelvic function score and classification at last follow-up were recorded and compared between the two groups. Results In the 5G group, 180 screws were implanted during surgery, while 213 screws were implanted in the control group. The 5G group demonstrated significantly reduced intraoperative blood loss and shorter incision length compared to the control group (P<0.05). No significant difference was observed between the two groups in terms of operation time or hospital stay (P>0.05). Radiographic evaluation revealed excellent and good reduction rates of 98.8% (79/80) in the 5G group and 97.5% (78/80) in the control group, while excellent and good screw placement accuracy rates were 98.3% (177/180) in the 5G group and 95.8% (204/213) in the control group. No significant difference was found between the two groups in maximum residual displacement, reduction quality, or screw placement accuracy (P>0.05). All patients were followed up 7-16 months (mean, 11.3 months), with no significant difference in follow-up duration between the groups (P>0.05). No perioperative or follow-up complication, such as wound infection, iatrogenic fractures, iatrogenic neurovascular injury, screw loosening or breakage, or nonunion, were observed in either group. The control group exhibited a worse degree of gait alteration compared to the 5G group (P<0.05), while no significant difference was found in incidences of squatting limitation or persistent pain (P>0.05). At last follow-up, no significant difference was observed between the groups in Majeed pelvic function scores or grading (P>0.05). Conclusion Compared with the local surgery group, 5G remote robotic surgery supported by remote expert technical guidance demonstrated smaller incision lengths, less intraoperative blood loss, and fewer postoperative complications, and was shown to be a precise, minimally invasive, safe, and reliable surgical method.

  • Application of robotic surgery in pancreatic cancer

    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.

  • Meta-analysis of leg length discrepancy after robot-assisted and traditional total hip arthroplasty

    Objective To systematically evaluate the difference in leg length discrepancy (LLD) between robot-assisted total hip arthroplasty (THA) and traditional THA. Methods The Cochrane Library, PubMed, Web of Science, EMbase, CNKI, Wanfang, VIP, and CBM databases were searched by computer to collect cohort studies of robot-assisted and traditional THAs from inception to August 11th, 2021. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias of the included studies. Meta-analysis was performed using RevMan 5.3 software. ResultsA total of 10 high-quality cohort studies were included. The results of Meta-analysis showed that compared with traditional THA, LLD after robot-assisted THA was smaller [MD=−1.64, 95%CI (−2.25, −1.04), P<0.001], Harris scores at 3 and 12 months after operation were higher [MD=1.50, 95%CI (0.44, 2.57), P=0.006; MD=7.60, 95%CI (2.51, 12.68), P=0.003]. However, the operative time was longer [MD=8.36, 95%CI (4.56, 12.17), P<0.000 1], and the postoperative acetabular anteversion angle was larger [MD=1.91, 95%CI (1.43, 2.40), P<0.001]. There was no significant difference in Harris score at 6 months, amnesia index (Forgotten joint score, FJS), postoperative acetabular abduction angle, and incidence of complication between the two groups (P>0.05). Conclusion Robot-assisted THA is superior to traditional THA in postoperative LLD.

  • The learning curve and operator's perception of pulmonary lobectomy with the da Vinci robot versus the domestic robot: A retrospective cohort study

    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.

  • Early effectiveness of robot-assisted total hip arthroplasty via direct superior approach

    ObjectiveTo evaluate the early effectiveness of the robot-assisted total hip arthroplasty (THA) via direct superior approach (DSA).MethodsBetween March 2021 and April 2021, 11 patients (11 hips) were treated with a robot-assisted THA via DSA. There were 7 males and 4 females, with an average age of 55 years (range, 26-73 years). There were 5 patients of osteoarthritis secondary to hip dysplasia and 6 patients of osteonecrosis of femoral head. Preoperative hip Harris score was 55.8±6.3. The operation time, volume of blood loss, length of incision, postoperative blood transfusion and hospital stay, and the incidence of surgical complications were recorded. The visual analogue scale (VAS) score and Harris score were used to evaluate hip joint pain and function. The leg length discrepancy (LLD) was measured on the X-ray films. The inclination angle and anteversion angle of the acetabular component were also measured, and the difference between the planned and actual values were compared.ResultsOne THA was performed via conventional posterolateral approach finally because of poor exposure. The rest of 10 THAs were performed with assistance of robotic arm via DSA. The average operation time was 89 minutes (range, 65-120 minutes); the average length of incision was 10.5 cm (range, 9-13 cm); and the average blood loss was 400 mL (range, 110-740 mL). One patient was given a blood transfusion for 2 unit. All incisions healed by first intention and no neurovascular injury, deep vein thrombosis, or fracture occurred. The length of hospital stay after operation was 2-6 days (mean, 4.4 days). The duration of follow-up was 1-3 months (mean, 2.1 months). The VAS score was 0 in 9 patients and 2 in 1 patient at the day of discharge. At last follow-up, the hip Harris score was 84.9±6.7, showing significant difference when compared with that before operation (t=−8.717, P=0.000). The inclination and anteversion angles were (37.4±2.0)° and (17.1±4.5)°, respectively, and there was no significant difference when compared with the planned values [(38.2±1.6)°, (16.6±3.7)°] (t=1.809, P=0.104; t=–1.103, P=0.299). The LLD ranged from –2 to 4 mm. No complication such as dislocation, aseptic loosening, or periprosthetic joint infection occurred. ConclusionThe robot-assisted THA via DSA has encouraged early effectiveness.

    Objective To investigate the effects of children’s crawling-promotion-training-robot on gross motor function and cognitive function in children with global developmental delay (GDD). Methods A total of 40 children with GDD admitted to the Department of Rehabilitation Medicine, Children’s Hospital of Nanjing Medical University were selected as the research subjects. By envelope method, the children were randomly and equally divided into experimental group and control group, with 20 cases in each group. The experimental group received children’s crawling-promotion-training-robot combined with conventional rehabilitation therapy, while the control group received manual crawling training combined with conventional rehabilitation therapy. Before and after treatment, the scores of Gross Motor Function Measure Scale-88 (GMFM-88) and Gesell Developmental Scale (GDS) were respectively used to evaluate gross motor function and cognitive function. Results There was no significant difference in gender (χ2=0.100, P=0.752) and age (t=0.053, P=0.962) between the two groups. Before treatment, there was no significant difference in GMFM-88 and GDS scores between the two groups (P>0.05). After treatment, there were statistically significant differences in GMFM-88 and GDS scores between the two groups (P<0.05). The comparison within the group showed that there were statistically significant differences in GMFM-88 and GDS scores between the two groups before and after treatment. Conclusion Children’s crawling-promotion-training-robot is more effective than manual crawling training in improving gross motor function and cognitive function in children with GDD.

    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.
