  Abstract: Abstract Median arcuate ligament syndrome (MALS) is rare syndrome and is diagnosis of exclusion. Though first robotic median arcuate ligament release (MALR) was described in 2007, there are only a few case reports (CR), case series (CS), and retrospective cohort studies (RCS) in the published literature. The purpose of this study was to assess the feasibility and safety of robotic-assisted MALR (r-MALR). PubMed, Embase, and Cochrane databases were searched (last search December 2023) for articles reporting r-MALR. All studies including CR, CS, RCS reporting technical feasibility (operating time and rate of conversions), safety (intra-operative complications, blood loss, post-operative complications), and outcome (length of stay [LoS]) were included (PROSPERO: CRD42024502792). A total of 23 studies (8-CR, 5-CS, 10-RCS) with total 290 patients were available in the literature. Except 1-RCS, all studies reported age and mean age for CR was 40.38 ± 17.7, 36.08 ± 15.12 for CS, 39.72 ± 7.35 years for RS; except 2-RCS, all studies reported gender distribution and there were 57 males and 214 females. Operating time: 3-CR, 4-CS, 9-RCS reported operating time, and mean time was 111 ± 54, 131.69 ± 7.51, 117.34 ± 35.03 min, respectively. Conversion rate: All studies reported data on conversion and only four (1.37%) cases were converted—one to laparoscopic approach, three to open approach (1—inadvertent celiac arteriotomy, 2—reasons not mentioned). Intraoperative complications: only 5-CR, 4-CS, and 9-RCS reported data on intra-operative complications, and there were only 6 complications (1.5%): 1—inadvertent celiac arteriotomy converted to open; 3—unnamed vascular injuries (2 managed robotically, 1 converted to open); 1—bleeding managed robotically; there were no other reported injuries. Estimated blood loss ranged from 5 to 30 ml. Post-operative complications: 5-CR, 4-CS, 8-RCS described post-operative complications in 21 (7%) patients. Twenty cases were grade I, one was grade IIIa, and all managed successfully. LoS stay: 2-CR, 4-CS, 10-RCS reported LoS and overall, it was 2 days. r-MALR is reasonable, technically feasible, safe, and has acceptable outcomes. In addition, robotic approach provided superior vision, improved dexterity, precise, and easy circumferential dissection. PROSPERO registration: The protocol was registered in the PROSPERO database (CRD42024502792).

  Abstract: Abstract Robotic surgery is a rapidly expanding field, given the wide variety of new robotic platforms emerging. Looking at the training of surgeons in robotic surgery is of extreme necessity and urgency, considering the ongoing technological advancements. In this research, the performance during the virtual reality simulation phase of training for robotic surgery was analyzed. It was observed that, in addition to the lack of consensus among societies regarding the required simulation hours, there is no guidance on the best curriculum to be adopted. From the data in this study, it can be inferred that the more advanced skills have fewer proficient individuals, meaning that fewer surgeons in training have reached proficiency in all skill exercises. Even with differences in the number of exercises performed proficiently between groups that underwent varying amounts of simulation time, there is no statistically significant difference in the proportion between them.

  Abstract: Abstract To test the impact of the prostate-gland asymmetry on continence rates, namely 3- and 12-month continence recovery, in prostate cancer (PCa) patients who underwent robot-assisted radical prostatectomy (RARP). Within our institutional database, RARP patients with complete preoperative MRI features and 12 months follow-up were enrolled (2021–2023). The population has been stratified according to the presence or absence of prostate-gland asymmetry (defined as the presence of median lobe or side lobe dominance). Multivariable logistic regression models (LRMs) predicting the continence rate at 3 and 12 months after RARP were fitted in the overall population. Subsequently, the LRMs were repeated in two subgroup analyses based on prostate size (≤ 40 vs > 40 ml). Overall, 248 consecutive RARP patients were included in the analyses. The rate of continence at 3 and 12 months was 69 and 72%, respectively. After multivariable LRM the bladder neck sparing approach (OR 3.15, 95% CI 1.68–6.09, p value < 0.001) and BMI (OR 0.90, 95% CI 0.82–0.97, p = 0.006) were independent predictors of recovery continence at 3 months. The prostate-gland asymmetry independently predicted lower continence rates at 3 (OR 0.33, 95% CI 0.13–0.83, p = 0.02) and 12 months (OR 0.31, 95% CI 0.10–0.90, p = 0.03) in patients with prostate size ≤ 40 ml. The presence of prostate lobe asymmetry negatively affected the recovery of 3- and 12-months continence in prostate glands ≤ 40 mL. These observations should be considered in the preoperative planning and counseling of RARP patients.

  Abstract: Abstract Robotic pyelolithotomy continues to gain attention as an alternative to percutaneous nephrolithotomy (PCNL) for managing complex renal stones. We performed a single-arm meta-analysis and systematically searched the English-language literature published in PubMed, Web of Science, Scopus, and Google Scholar databases up to June 2024. The risk of non-randomized bias was assessed using ROBINS-I, and the quality of the literature was assessed using MINORS (Methodological Index for Non-Randomized Studies). Merger parameters were calculated using Stata16/SE under a random-effects model. Five non-comparative single-arm studies were included in the meta-analysis. Results showed that the operative time for robotic pyelolithotomy was 168.10 min (95% CI 133.63, 202.56). The hospital stay was 2.63 days (95% CI 0.96, 4.29), and blood loss was 44.13 ml (95% CI 19.76, 68.51). The stone clearance rate was 87% (95% CI 79–93%). The incidence of minor postoperative complications (Clavien grade I–II) was 23.7% (95% CI 13.4–35.8%), and the incidence of major complications (Clavien grade ≥ III) was 7% (95% CI 0.3–20.7%).The safety and efficacy of robotic pyelolithotomy in treating complex renal stones are acceptable, but future large prospective cohort studies are needed to validate the treatment.

  Abstract: Abstract Robotic assisted partial nephrectomy (RPN) has emerged in urologic practice for the management of appropriately sized renal masses. We provide a 20-year comparison of the outcomes of open partial nephrectomy (OPN) versus RPN for renal cell carcinoma (RCC) at our institution. An IRB-approved retrospective review was conducted of RCC patients at a single institution from 2000 to 2022 who underwent RPN or OPN. In addition to demographics, procedural details including ischemia and operative time were collected. Oncologic outcomes were evaluated through Kaplan–Meier statistical analysis to determine recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) analysis. 849 patients underwent RPN while 385 underwent OPN. 61% were male with average age of 58.8 ± 12.8 years. Operative time was shorter in the open group (184 vs 200 min, p = 0.002), as was ischemia time (16 vs 19 min, p = 0.047). However, after 2012, RPN became more common than OPN with improving ischemia time. RPN patients had significantly improved RFS (HR 0.45, p = 0.0004) and OS (HR 0.51, p = 0.0016) when controlled for T-stage and margin status. More > pT1 masses were managed with OPN than RPN (11.2 vs 5.4%, p < 0.0001). At our institution, RPN had an increasing incidence with reduced ischemia time compared to OPN over the last 10 years. While higher stage renal masses were more often managed with OPN, selective use of RPN does offer improved oncologic outcomes. Further investigation is needed to evaluate optimization of the selection of RPN versus OPN in the nephron-sparing management of renal masses.

  Abstract: Abstract Exploration of surgical precision in robotic procedures is extensive, yet lacks a unified framework for comparability. This study examines tissue handling precision by comparing the per-minute blood loss rate between robotic and open partial nephrectomy. A literature search from August 2022 to June 2024 identified 43 relevant studies providing data on estimated blood loss and procedure duration. The expected values and standard errors of these variables were used to compute the per-minute blood loss rate (Q). Meta-analytical methods estimated pooled and subgroup-level mean differences, favoring robotic surgery (MDQ = − 1.043 ml/min, CI95% = [− 1.338; − 0.747]). Subgroup analyses by publication year, patient matching, referral center count, and ROBINS-I status consistently supported this advantage. Sensitivity analyses confirmed the above benefit in studies with increased accuracy in reported results (MDQ = – 0.957 ml/min, CI95% = [– 1.269; – 0.646]), low risk of bias involving matched comparisons (MDQ = – 0.563 ml/min, CI95% = [– 0.716; – 0.410]), large sample sizes and increased statistical power (MDQ = – 0.780 ml/min, CI95% = [– 1.134; – 0.425]), and multicenter analyses with patient matching (MDQ = – 0.481 ml/min, CI95% = [– 0.698; – 0.263]). The subsequent analysis of correlation between the original variables suggested a slight reduction in the robotic advantage when the latter were proportionally related. Multilevel meta-regression at both temporal and qualitative scales consistently indicated a comparative benefit of the robotic approach. Potentially, lower per-minute blood loss compared to open surgery suggests that robotic partial nephrectomy demonstrates enhanced precision in tissue handling.

  Abstract: Abstract High-performance miniature surgical instruments play an important role in complicated minimally invasive surgery (MIS). Based on in-depth analysis of the requirements of MIS and the characteristics of the existing minimally invasive surgical instruments, a multiple degrees of freedom (DOF) robotic surgical instrument with decoupled pose was proposed. Firstly, the design concept of the pose decoupling instrument was described in detail, and its physical structure, transmission structure, and mechanical properties were designed and analyzed. A surgical instrument control algorithm based on the master–slave mode was established. Finally, a physical prototype was developed, and its motion ranges of joints, load capacity, and suture operation performance were comprehensively evaluated, which confirmed the effectiveness of the proposed minimally invasive robotic surgical instrument.

  Abstract: Abstract Our objective was to investigate the long-term functional outcomes of robot-assisted partial nephrectomy (RAPN) combined with three-dimensional (3D) imaging. The 3D images, reconstructed using computed tomography, were introduced in RAPN procedures. The demographic, oncological, functional, and volumetric outcomes of 296 patients who underwent RAPN with and without 3D imaging between 2013 and 2021 were analyzed retrospectively. Propensity score matching (1:1) was performed to adjust for potential baseline confounders. After matching, 71 patients were allocated to each group. In the 3D RAPN (3DRPN) group, functional outcomes significantly improved: the number of patients with over 90% estimated glomerular filtration rate (eGFR) preservation rate (40 vs. 43, P = 0.044), eGFR preservation rate (88.0% vs. 91.6%, P = 0.006), the number of patients with chronic kidney disease (CKD) upstaging (26 vs. 13, P = 0.023), and split renal function preservation rate (operated kidney: 84.9% vs. 88.5%, P = 0.015). The 3DRPN group showed superiority in terms of >90% eGFR preservation (P = 0.010), CKD upstaging-free survival rates (P < 0.001), and volumetric outcomes (excess parenchymal volume: 27.9 vs. 17.7 mL, P = 0.030; parenchyma volume preservation rate: 81.6% vs. 88.8%, P = 0.006). Three-dimensional imaging was positively associated with eGFR preservation (P = 0.023, odds ratio: 2.34) and prevention of CKD upstaging (P = 0.013, odds ratio: 2.90). In this study, RAPN combined with 3D imaging underscored the preservation of eGFR > 90% and the prevention of CKD upstaging by improving the preservation rate of renal parenchyma and split renal function.

  Abstract: Abstract This study aimed to analyze perioperative results in robot-assisted laparoscopic urological surgeries, comparing the AirSeal system with traditional pneumoperitoneum systems. This study adhered to the PRISMA guidelines for conducting systematic reviews and meta-analyses. Extensive searches were conducted in PubMed, EMBASE, and Google Scholar, including randomized controlled trials (RCTs) and cohort studies up to June 15, 2024. A combined examination of the studies found that the AirSeal system had superior results in terms of surgery duration, end-tidal carbon dioxide levels, and tidal volume compared to the traditional pneumoperitoneum system. During robotic-assisted partial nephrectomy, the AirSeal team experienced a notable decrease in surgical time, ETCO2, and VT. In addition, the occurrence of SCE was lower in the AirSeal group. However, there were no significant differences observed between the groups regarding EBL, LOHS, overall complications, and major complications. Compared to conventional pneumoperitoneum systems, the AirSeal system offers several advantages in robot-assisted laparoscopic urological surgery: reduced operative time, lower end-tidal CO2 pressure, and decreased tidal volume. Furthermore, implementing the AirSeal system does not lead to higher rates of complications, estimated blood loss, or lengthier hospital stays.

  Abstract: Abstract Standardised proficiency-based progression is the cornerstone of safe robotic skills acquisition, however, is currently lacking within surgical training curricula. Expert consensuses have defined a modular pathway to accredit surgeons. This study aimed to address the lack of a formal, pre-clinical core robotic skills, proficiency-based accreditation curriculum in the UK. Novice robotic participants underwent a four-day pre-clinical core robotic skills curriculum incorporating multimodal assessment. Modifiable-Global Evaluative Assessment of Robotic Skills (M-GEARS), VR-automated performance metrics (APMs) and Objective Clinical Human Reliability Analysis (OCHRA) error methodology assessed performance at the beginning and end of training. Messick’s validity concept and a curriculum evaluation model were utilised. Feedback was collated. Proficiency-based progression, benchmarking, tool validity and reliability was assessed through comparative and correlational statistical methods. Forty-seven participants were recruited. Objective assessment of VR and dry models across M-GEARS, APMs and OCHRA demonstrated significant improvements in technical skill (p < 0.001). Concurrent validity between assessment tools demonstrated strong correlation in dry and VR tasks (r = 0.64–0.92, p < 0.001). OCHRA Inter-rater reliability was excellent (r = 0.93, p < 0.001 and 81% matched error events). A benchmark was established with M-GEARS and for the curriculum at 80%. Thirty (63.82%) participants passed. Feedback was 5/5 stars on average, with 100% recommendation. Curriculum evaluation fulfilled all five domains of Messick’s validity. Core robotic surgical skills training can be objectively evaluated and benchmarked to provide accreditation in basic robotic skills. A strategy is necessary to enrol standardised curricula into national surgical training at an early stage to ensure patient safety.

  Abstract: Abstract The use of 3-dimensional (3D) technology has become increasingly popular across different surgical specialities to improve surgical outcomes. 3D technology has the potential to be applied to robotic assisted radical prostatectomy to visualise the patient’s prostate anatomy to be used as a preoperative and peri operative surgical guide. This literature review aims to analyse all relevant pre-existing research on this topic. Following PRISMA guidelines, a search was carried out on PubMed, Medline, and Scopus. A total of seven studies were included in this literature review; two of which used printed-3D models and the remaining five using virtual augmented reality (AR) 3D models. Results displayed variation with select studies presenting that the use of 3D models enhances surgical outcomes and reduces complications whilst others displayed conflicting evidence. The use of 3D modelling within surgery has potential to improve various areas. This includes the potential surgical outcomes, including complication rates, due to improved planning and education.

  Abstract: Abstract The application of a robotic platform in the bariatric surgical field is intended to enhance the already established advantages of minimally invasive surgery in terms of both technical and clinical outcomes. These advantages are especially relevant for technically challenging multiquadrant operations such as Roux-en-Y Gastric Bypass (RYGB). Consequently, robotic-assisted surgery has emerged as a possible application for bariatric surgeries. The study attempts to assess feasibility and safety of the Hugo™-Robotic-Assisted Surgery System (Hugo™-RAS) platform compared to the DaVinci® Surgical System (DaVinci®-SS) with a focus on complication rates and operative times. We retrospectively reviewed bariatric procedures performed from January 2013 until December 2023. We included all robotic RYGBs performed using Hugo™-RAS and DaVinci®-SS platforms. The study utilized Propensity Score Matching (PSM) analysis to address bias in selection, matching patients based on age, gender, body mass index, comorbidities and past abdominal operations. One hundred thirty-five patients were identified: 90 DaVinci®-SS and 45 Hugo™-RAS procedures. After PSM, each group consisted of 45 patients. There was no discernible disparity observed in relation to early (≤ 30 days) postoperative complications rate (p = 1), mean operative time (for docking time, console time and total operative time: p = 0.176, p = 0.678, p = 0.229, respectively) and postoperative hospital stay (p = 0.052) between DaVinci®-RSS and Hugo™-RAS procedures. Our results suggest that application of both Hugo™-RAS and DaVinci®-SS robotic platforms to RYGB is related to comparable safety profiles. Although DaVinci®-SS remains the most widely adopted platform in clinical practice, this study underscores the potential role of the Hugo™-RAS to provide effective solutions in robotic bariatric procedures.

  Abstract: Abstract The “Robotic Curriculum for young Surgeons” (RoCS) was launched 03/2020 to address the increasing importance of robotics in surgical training. It aims to provide residents with foundational robotic skills by involving them early in their training. This study evaluated the impact of RoCS’ integration into clinical routine on patient outcomes. Two cohorts were compared regarding the implementation of RoCS: Cohort 1 (before RoCS) included all robot-assisted procedures between 2017 and 03/2020 (n = 174 adults) retrospectively; Cohort 2 (after RoCS) included all adults (n = 177) who underwent robotic procedures between 03/2020 and 2021 prospectively. Statistical analysis covered demographics, perioperative parameters, and follow-up data, including mortality and morbidity. Subgroup analysis for both cohorts was organ-related (upper gastrointestinal tract (UGI), colorectal (CR), hepatopancreaticobiliary system (HPB)). Sixteen procedures were excluded due to heterogeneity. In-hospital, 30-, 90-day morbidity and mortality showed no significant differences between both cohorts, including organ-related subgroups. For UGI, no significant intraoperative parameter changes were observed. Surgery duration decreased significantly in CR and HPB procedures (p = 0.018 and p < 0.001). Estimated blood loss significantly decreased for CR operations (p = 0.001). The conversion rate decreased for HPB operations (p = 0.005). Length of hospitalization decreased for CR (p = 0.015) and HPB (p = 0.006) procedures. Oncologic quality, measured by histopathologic R0-resections, showed no significant changes. RoCS can be safely integrated into clinical practice without compromising patient safety or oncologic quality. It serves as an effective training pathway to guide robotic novices through their first steps in robotic surgery, offering promising potential for skill acquisition and career advancement.

  Abstract: Abstract Despite total knee arthroplasty (TKA) being the gold standard for end-stage knee osteoarthritis, 20% of patients remain dissatisfied. Robotic-assisted arthroplasty promises unparalleled control of the accuracy of bone cuts, implant positioning, control of gap balance, and resultant hip–knee–ankle (HKA) axis. Patients underwent clinical and radiological assessments, including knee CT scans and patient-reported outcome measures (PROMs), preoperatively. Follow-up assessments were conducted at 2 weeks, 6 weeks, and 3 months post-operatively, with imaging repeated at 6 weeks. A total of 155 patients underwent robotic-assisted TKA and have completed 3 months of follow-up. Mean pre-operative HKA axis was 7.39 ± 5.52 degrees varus, improving to 1.34 ± 2.22 degrees varus post-operatively. Restoration of HKA axis was 0.76 ± 1.9 degrees from intra-operative planning (p < 0.0005). Implant placement accuracy in the coronal plane was 0.08 ± 1.36 degrees (p = 0.458) for the femoral component and 0.71 ± 1.3 degrees (p < 0.0005) for the tibial component. Rotational alignment mean deviation was 0.39 ± 1.49 degrees (p = 0.001). Most patients (98.1%) had ≤ 2 mm difference in extension–flexion gaps. PROM scores showed improvement and exceeded pre-operative scores by 6 weeks post-surgery. Robotic-assisted knee arthroplasty provides precise control over traditionally subjective factors, demonstrating excellent early post-operative outcomes. Level of evidence Prospective observational study—II.

  Abstract: Abstract The objective of this study was to perform a comprehensive pooled analysis aimed at comparing the efficacy and safety of percutaneous ablation (PCA) versus minimally invasive partial nephrectomy (MIPN), including robotic and laparoscopic approaches, in patients diagnosed with cT1 renal tumors. We conducted a comprehensive search across four major electronic databases: PubMed, Embase, Web of Science, and the Cochrane Library, targeting studies published in English up to April 2024. The primary outcomes evaluated in this analysis included perioperative outcomes, functional outcomes, and oncological outcomes. A total of 2449 patients across 17 studies were included in the analysis. PCA demonstrated superior outcomes compared to MIPN in terms of shorter hospital stays (WMD: − 2.13 days; 95% Confidence Interval [CI]: − 3.29, − 0.97; p = 0.0003), reduced operative times (WMD: − 109.99 min; 95% CI: − 141.40, − 78.59; p < 0.00001), and lower overall complication rates (OR: 0.54; 95% CI: 0.40, 0.74; p = 0.0001). However, PCA was associated with a higher rate of local recurrence when compared to MIPN (OR: 3.81; 95% CI: 2.45, 5.92; p < 0.00001). Additionally, no significant differences were observed in major complications, estimated glomerular filtration rate decline, creatinine variation, overall survival, recurrence-free survival, and disease-free survival between the two treatment modalities. PCA presents a notable disadvantage regarding local recurrence rates in comparison to MIPN. However, PCA offers several advantages over MIPN, including shorter durations of hospital stay, reduced operative times, and lower complication rates, while achieving similar outcomes in other oncologic metrics.

  Abstract: Abstract Understanding alignment and gap balancing in Total Knee Arthroplasty (TKA) can be challenging for trainee and experienced orthopedic surgeons. Traditional learning methods may not effectively translate to real-life scenarios. The advent of advanced technologies like robotic surgery and navigation systems has revolutionized intraoperative understanding of gap balancing techniques. This trial aims to investigate the effectiveness of robotic TKA planning software in educating trainees about alignment and ligament balancing. We hypothesize that a single session with the software will significantly enhance trainees’ understanding of these techniques. This UK-based single-center, two-arm, group parallel randomized controlled trial was conducted during a national robotic arthroplasty symposium. It aims to evaluate the effect of robotic knee arthroplasty software training on understanding TKA alignment and gap balancing principles using Multiple Choice Questions (MCQs). The MCQ test was crafted based on established guidelines from a different institution with expert consensus in the field. Our study revealed that baseline knowledge of gap balancing and alignment principles was generally low among all participants. However, the intervention group, which received comprehensive robotic software training, demonstrated a significant improvement in their MCQ scores compared to the control group, which did not undergo the training. In conclusion, our study demonstrates that robotic arthroplasty software training significantly improves the understanding of TKA alignment and balancing principles among orthopedic trainees.

  Abstract: Abstract This investigation sought to conduct a comprehensive meta-analysis to assess the comparative effectiveness and safety of percutaneous ablation (PCA) versus robotic-assisted partial nephrectomy (RAPN) among individuals diagnosed with cT1 renal tumors. This study rigorously followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to conduct a systematic review and meta-analysis. A systematic search was carried out in the PubMed, Embase, Web of Science, and Cochrane Library databases, focusing on studies published in English through February 2024. We focused on evaluating primary outcomes, specifically perioperative outcomes, functional outcomes, and oncological outcomes. In this analysis, data from 1534 patients across 13 studies were evaluated. PCA was found to have advantageous outcomes in comparison to RAPN regarding hospital stay durations, with a Weighted Mean Difference (WMD) of − 2.03 days (95% Confidence Interval [CI]: -3.78 to − 0.27; p = 0.02), operative times (WMD: -106.75 min; 95% CI: − 170.78 to − 42.72; p = 0.001), and overall complication rates (Odds Ratio [OR]: 0.61; 95% CI: 0.42 to 0.89; p = 0.01). Conversely, PCA showed a higher incidence of local recurrence compared to RAPN, with an OR of 3.20 (95% CI: 1.91 to 5.35; p < 0.00001). Moreover, there were no statistically significant differences between the two treatments in terms of major complications, declines in estimated glomerular filtration rates (eGFR), variations in creatinine levels, overall survival rates, and recurrence-free survival. While PCA exhibits higher local recurrence rates than RAPN, it also presents significant advantages, such as shorter hospital stays, decreased operative durations, and lower complication rates. This juxtaposition underscores the urgent need for further, more rigorous research to substantiate these findings.

  Abstract: Abstract Although the safety and short-term outcomes of robotic surgery for sigmoid colon and rectal cancer patients are well-documented, there is limited research on the long-term survival outcomes of robotic colorectal surgery. This is a retrospective study that includes 502 patients who underwent either laparoscopic or robotic anterior resection and abdominoperineal resection for rectal or sigmoid colon cancer between August 2016 and September 2021. All patients were diagnosed with rectal or sigmoid colon adenocarcinoma. Propensity score matching (PSM) was implemented to minimize selection bias. Perioperative outcomes, complication rates, and pathological data were evaluated and compared. The 5-year overall survival rate and disease-free survival rate were calculated and compared. Before matching, patients in the robotic group had earlier pathological T and N stages and were more likely to have received neoadjuvant chemoradiotherapy compared to the laparoscopic group. After matching, most clinicopathological outcomes were similar between the two groups, but the robotic group had longer operative times and a lower conversion rate to open surgery compared with laparoscopic group. After matching for clinical factors, the 5-year DFS rates were 88.19% for the robotic group and 82.46% for the laparoscopic group (P = 0.122), and the OS rates were 90.5% and 79.5% (P = 0.342), showing no significant differences. In the stratified analysis, patients in the robotic surgery group had significantly higher 5-year DFS rates in the following subgroups: age < 65 years, TNM stage I-II, received neoadjuvant therapy, and primary tumor located in the rectum. The safety and efficacy of robotic surgery for sigmoid colon and rectal cancer were validated compared to laparoscopic surgery, with both groups of patients exhibiting comparable long-term prognoses.
