Background
Colorectal surgical procedures may benefit from a minimally invasive approach in children, although there are few studies.
Methods
A retrospective, single-centre observational study was conducted on paediatric patients who underwent colorectal robotic-assisted surgery between 2011 and 2022.
Results
A total of 50 patients (33 male; 17 female) were included, with a median age of 4.8 years (IQR:2.5–6.3 years). The main indication was robotic Soave pull-through for Hirschsprung's disease in 21 cases. No conversions or intraoperative complications were reported. Operative time varied depending on the procedure, with a median of 183 min (IQR:151–224 min). Median hospital stay was 4 days (IQR:3–5 days). Four postoperative complications were observed, two of them Clavien-Dindo IIIb (one colo-anal partial dehiscence and one anastomotic leak after megasigmoid resection). Regarding long-term follow-up (median 7.6 years; IQR:4.8–10.6 years), 4 patients (8%) required surgical reintervention.
Conclusion
Colorectal robotic-assisted surgery encompasses several procedures with low complication rates and satisfactory long-term outcomes.

The aim of this study is to assess the impact of obesity on the perioperative outcomes in robotic pancreaticoduodenectomy (RPD), rarely documented.
Methods
A total of 886 patients undergoing RPD or open pancreaticoduodenectomy (OPD) were enroled. These patients were categorised into the obese RPD, non-obese RPD and obese OPD groups.
Results
Operation time was longer in obese RPD compared with non-obese RPD and obese OPD (median: 9.5 vs. 7.5 and 8.0 h). Blood loss was lower in both RPD groups than in the obese OPD group (median: 200 and 120 vs. 500 c.c.). Surgical mortality and morbidity were comparable between these three groups. Delayed gastric emptying (DGE) occurred less frequently in both RPD groups than obese OPD (7.5% and 4.4% vs. 19.1%).
Conclusions
Obesity does not exert a negative impact on the perioperative outcomes in RPD, except for longer operation times. RPD has emerged as a safe and viable surgical approach for obese patients.

Background
Minimally invasive distal pancreatectomy offers recognised benefits over open surgery. Robotic surgery, with its shorter learning curve and technical advancements, presents a promising alternative to laparoscopy in managing pancreatic diseases.
Methods
This study enrolled consecutive patients undergoing distal pancreatectomy between January 2013 and May 2022. After propensity score matching, perioperative and medium-term outcomes were compared between robotic and open procedures.
Results
Among 79 patients analysed, 50 were eligible after matching. Both groups showed similar demographics, with 11% experiencing grade III-IV complications, and one patient died within 90 days after surgery. Robotic surgery exhibited longer operating times but allowed for earlier refeeding, drain removal, canalisation, and shorter hospital stays compared with open surgery. Spleen preservation rates, postoperative pancreatic fistula occurrences and survival were comparable between the groups.
Conclusions
Overall, robotic and open distal pancreatectomy demonstrated similar outcomes, with robotic surgery offering advantages in certain postoperative parameters despite longer operation times.

In recent years, laparoscopic surgical robots have rapidly developed. However, most focus on the overall robotic systems, with few summaries on the laparoscopic surgical robots and the master manipulators.
Methods
This paper provides a summary and analysis of typical laparoscopic surgical robots, including the strengths and limitations of existing laparoscopic surgical robots. Additionally, the master manipulators are analysed and summarised from four aspects: structural design and optimization, time-varying delays, tremor suppression and force feedback. Further classification and summary are made based on the different methods used in each study.
Results
Laparoscopic surgical robots and the master manipulators still have some limitations. Therefore, the development trends of the laparoscopic surgical robots and the master manipulators are discussed from four aspects: structural materials, remote surgery, intelligence and human–machine interaction.
Conclusion
With the continuous advancement of technology, laparoscopic surgical robots will play an increasingly important role in the field of surgery.

Background
Cable-driven continuum manipulators (CDCMs) enable scar-free procedures but face limitations in workspace and control accuracy due to hysteresis.
Methods
We introduce an extensible CDCM with a semi-active mechanism (SAM) and develop a real-time hysteresis compensation control algorithm using a temporal convolution network (TCN) based on data collected from fiducial markers and RGBD sensing.
Results
Performance validation shows the proposed controller significantly reduces hysteresis by up to 69.5% in random trajectory tracking test and approximately 26% in the box pointing task.
Conclusion
The SAM mechanism enables access to various lesions without damaging surrounding tissues. The proposed controller with TCN-based compensation effectively predicts hysteresis behaviour and minimises position and joint angle errors in real-time, which has the potential to enhance surgical task performance.

We compared the surgical outcomes of patients who underwent robot-assisted radical prostatectomy (RARP) using hinotori with those of patients who underwent RARP using da Vinci Xi through propensity score matching to evaluate the potential benefits and efficacy of hinotori.
Methods
Perioperative data of patients who underwent RARP between 2017 and 2023 were retrospectively evaluated.
Results
After adjusting for preoperative risk factors, each group comprised 118 propensity score-matched patients. Both median total operative time and median console time were significantly longer in the hinotori group (median differences, 26 and 23 min, respectively). Although the hinotori group had lower estimated blood loss, no significant differences were noted between the groups in postoperative complications, positive surgical margin rates, 12-month biochemical recurrence rates, and urinary continence recovery rates.
Conclusions
Although RARP requires more time with hinotori, our study demonstrated that RARP can be performed safely and effectively immediately after the installation of hinotori.

Robot-assisted systems have predominantly relied on teleoperation, where visual feedback is the primary source of information. However, advances in tactile sensing and displays offer new opportunities to enhance surgical transparency, efficiency, and safety.
Methods
A PRISMA-guided search was conducted across PubMed, IEEE Xplore, Scopus, and Web of Science databases to identify relevant studies.
Results
Out of 645 screened articles, 98 met the inclusion criteria, and 33 were included in the final review. The review discusses various tactile feedback stimulus types, applications, and challenges in the context of robot-assisted minimally invasive surgery.
Conclusion
While kinaesthetic feedback has been extensively explored to restore the natural interaction between the surgeon and the surgical environment, tactile feedback remains largely confined to research settings. This is due to significant challenges in integrating tactile feedback into robotic systems and current limitations of sensing technologies.

In-bore MRI prostate biopsy offers improved visualisation and detection of significant prostate cancer; however, it is not widely practiced in cancer diagnosis due to its associated costs.
Methods
This work introduces the first prototype towards a 7-degrees-of-freedom (DOF) MRI-conditional piezoelectrically actuated robotic system for transperineal prostate biopsy. The robot enables needle insertions in the desired trajectories. Kinematic and static models of the active needle as well as automated control of the robot are presented.
Results
It is shown that the controller can force the needle to realize the reference sine and triangular bending angles with an accuracy of 1.78 and 1.88°, respectively, in air. The trajectory tracking capability of the system in free space is shown with an RMS error of 0.86 mm and a standard deviation of 0.36 mm.
Conclusions
The robot's capability to steer the needle towards target inside a phantom and extract a sample was evaluated.

Background
Most patients present at high risk of perioperative pressure injury. Patients may experience severe agony from pressure injuries, which can also result in potentially fatal infections and increase hospital stays and medical expenses. This is a critical issue that requires immediate attention and resolution.
Methods
From December 2019 to August 2023, 335 patients receiving Da vinci surgery in a grade A tertiary hospital were chosen to serve as the participants, and univariate analysis and patients undergoing Da vinci surgery had their risk factors for pressure injuries screened using logistic regression analysis, and in patients having Da vinci surgery, a pressure injury risk prediction model was developed.
Results
Among 335 patients, 195 patients acquired pressure injuries, and the results of logistic regression analysis showed that age, length of surgery, BMI, and nasogastric tube (NGT) were independent risk factors for pressure injuries (p < 0.05).

Background
Minimally invasive internal fixation is the preferred treatment option for femoral shaft fractures. However, there are problems such as invisibility, inaccuracy and instability in the process of plate implantation.
Methods
In this paper, a dual-mode robot-assisted plate implantation method was proposed by combining a starting point determination algorithm, motion capture, deep learning and robotics.
Results
The neural network model planned the plate implantation trajectory according to patient's condition. Then, the advantages of high stability and high precision of the robotic arm were used for plate implantation.
Conclusion
The trend and fluctuation of the plate implantation trajectories obtained using this method met clinical requirements. Furthermore, the robotic arm implantation process was safe.
