Inguinal hernia repair is one of the most commonly performed surgical procedures worldwide, with over 20 million cases annually. The evolution of hernia surgery has transitioned from tension-based techniques to tension-free approaches, significantly reducing recurrence rates. This review explores the history, advancements, and current trends in minimally invasive inguinal hernia repair, focusing on laparoscopic techniques such as transabdominal preperitoneal (TAPP), totally extraperitoneal (TEP), single-incision laparoscopic surgery (SILS), and robotic-assisted repair. The importance of prosthetic meshes is emphasized, detailing their mechanical properties, pore size, weight classifications, and biocompatibility. Additionally, various mesh fixation methods—including tacks, sutures, and glues—are analyzed, with a discussion on their impact on postoperative complications such as chronic pain, adhesions, and infection risk. The debate between TAPP and TEP techniques is examined, highlighting the ongoing quest to determine the most effective approach. Emerging advancements, including drug-loaded meshes and dual-layered prosthetics, aim to improve integration and reduce complications. Despite significant progress, no universally superior technique or mesh exists, underscoring the need for individualized surgical approaches. Future research should focus on optimizing materials, refining fixation strategies, and enhancing patient outcomes in minimally invasive hernia repair. Full article

Since its development in 1904, radical prostatectomy (RP) has remained a fundamental surgical option in the management of localised prostate cancer. Over time, continuous advancements in surgical techniques have improved oncological outcomes while reducing functional complications. This narrative review explores the evolution of RP, depicting its progression from the traditional open approach to minimally invasive laparoscopic and robotic-assisted techniques. Key developments in RP techniques, including nerve-sparing, bladder neck-sparing and Retzius-sparing techniques as well as enhanced perioperative management, have contributed to reduced postoperative complications, namely incontinence and erectile dysfunction. Additionally, technological innovations such as augmented reality, utilising indocyanine green for improved visualisation of prostatic boundaries and illuminare-1 to easily identify nerves intraoperatively, artificial intelligence, and novel molecular imaging technologies such as PSMA PETs for improved margin assessment are shaping the future of RPs. Despite these advancements, challenges persist, including a steep learning curve associated with newer techniques, disparities in access due to cost considerations, and a lack of standardised outcome measures across different surgical approaches. This review provides insight into current trends, ongoing challenges, and future directions that may further refine surgical precision, enhance patient safety, and improve long-term treatment success in prostate cancer management.

Real-time 3D reconstruction in minimally invasive surgery improves depth perception and supports intraoperative decision-making and navigation. However, endoscopic imaging presents significant challenges, such as specular reflections, low-texture surfaces, and tissue deformation. We present a novel, deterministic and iterative stereo-matching method based on adaptive support weights that is tailored to these constraints. The algorithm is implemented in CUDA and C++ to enable real-time performance. We evaluated our method on the Stereo Correspondence and Reconstruction of Endoscopic Data (SCARED) dataset and a custom synthetic dataset using the mean absolute error (MAE), root mean square error (RMSE), and frame rate as metrics. On SCARED datasets 8 and 9, our method achieves MAEs of 3.79 mm and 3.61 mm, achieving 24.9 FPS on a system with an AMD Ryzen 9 5950X and NVIDIA RTX 3090. To the best of our knowledge, these results are on par with or surpass existing deterministic stereo-matching approaches. On synthetic data, which eliminates real-world imaging errors, the method achieves an MAE of 140.06 μm and an RMSE of 251.9 μm, highlighting its performance ceiling under noise-free, idealized conditions. Our method focuses on single-shot 3D reconstruction as a basis for stereo frame stitching and full-scene modeling. It provides accurate, deterministic, real-time depth estimation under clinically relevant conditions and has the potential to be integrated into surgical navigation, robotic assistance, and augmented reality workflows.

Objective: This study compares the surgical and oncological outcomes of minimally invasive robotic (RLP) and laparoscopic (LLP) left pancreatectomy in pancreatic cancer (PC) patients. Methods: Data from patients who underwent minimally invasive left pancreatectomy between 2013 and 2023 were analyzed. Two groups were identified: RLP and LLP. Perioperative outcomes were compared, including operative time, blood loss, conversion rate, and postoperative complications. Oncological outcomes included margin status, lymph node retrieval, lymph node status, overall survival (OS), and disease-free survival (DFS). Results: Fifty-four patients were divided into the LLP (n = 39) and RLP (n = 15) groups. The median operative time was shorter for LLP than RLP [260 min vs. 366 min, p = 0.007]. Blood loss and conversion rates were comparable (p > 0.05). In the LLP group, significantly more lymph nodes were harvested (29 vs. 19, p = 0.05), and a higher percentage of positive lymph nodes was noted (72% vs. 40%, p = 0.033). No significant difference was found in the R0 resection status (82% vs. 73%, p = 0.358). After a median follow-up of 26 months, OS (23 months vs. 34 months, p = 0.812) and DFS (17 months vs. 16 months, p = 0.635) were similar. Conclusion: RLP provides outcomes identical to LLP in treating body–tail pancreatic cancer, with further studies needed to confirm its long-term oncological efficacy. Full article

Background: Teaching methodology has recently undergone significant evolution from traditional apprenticeship models as we adapt to ever-increasing rates of technological advancement. Big data, artificial intelligence, and machine learning are on the precipice of revolutionising all aspects of surgical practice, with far-reaching implications. Robotic platforms will increase in autonomy as machine learning rapidly becomes more sophisticated, and therefore training requirements will no longer slow innovation. Materials and Methods: A search of published studies discussing surgeon training and computer-enhanced simulation robotics and emerging technologies using MEDLINE, PubMed, EMBASE, Scopus, CRANE, CINAHL, and Web of Science was performed in January 2024. Online resources associated with proprietary technologies related to the subject matter were also utilised. Results: Following a review of 3209 articles, 91 of which were published, relevant articles on aspects of robotics-based computer-enhanced simulation, technologies, and education were included. Publications ranged from RCTs, cohort studies, meta-analysis, and systematic reviews. The content of eight medical technology-based websites was analysed and included in this review to ensure the most up-to-date information was analysed. Discussion: Surgeons should aim to be at the forefront of this revolution for the ultimate benefit of patients. Surgical exposure will no longer be due to incidental experiences. Rather, surgeons and trainees will have access to a complete database of simulated minimally invasive procedures, and procedural simulation certification will likely become a requisite from graduation to live operating to maintain rigorous patient safety standards. This review provides a comprehensive outline of the current and future status of surgical training in the robotic and digital era. Full article

Background and Objectives: After introducing the single-port robotic surgical system (da-Vinci SP), thyroid surgeries using da-Vinci SP are becoming more popular. Although many methods have been designed for thyroidectomy using the da-Vinci SP, there are very few reports on methods that can perform not only thyroidectomy but also lateral cervical lymph node dissection. In this study, we want to report the first clinical experience with SPRA-MRND (Single Port Robotic Areolar-Modified Radical Neck dissection), using right breast access. Materials and Methods: From April 2024 to January 2025, a total of 24 robotic MRNDs were performed, of which 11 were SPRA-MRNDs. The remaining 13 were performed using conventional BABA surgery. The two data sets were compared through retrospective medical record analysis. Results: There were no significant differences regarding patient characteristics, pathologic variables and oncologic outcomes between the two groups. However, SPRA group showed significantly shorter operation time (182.1 ± 27.5 vs. 213.1 ± 31.5 min, p = 0.017), higher immediate postoperative calcium level (calcium: 8.7 ± 0.5 vs. 8.0 ± 0.8 mg/dL, p = 0.014) and lower drainage amount (98.1 ± 33.2 vs. 146.4 ± 43.2 mL, p = 0.005). Conclusions: Our initial experience has shown that SPRA-MRND is performed safely. We propose SPRA-MRND as a good method for minimally invasive robotic surgery. Full article

Background: In recent years, the use of minimally invasive approaches in pancreatic surgery has progressively increased. One of the key components of pancreaticoduodenectomy is the creation of a pancreato-enteric anastomosis, due to the high risk of postoperative complications, particularly the development of postoperative pancreatic fistula. Among the types of anastomoses, the Blumgart technique has gained popularity due to its ease of reproducibility. Methods: In this guide, we summarize and systematize step by step how to perform a feasible, reproductible and safe robotic Blumgart pancreaticojejunostomy, providing some instructions for its successful completion. Results: Despite the heterogeneity of the published data, duct-to-mucosa Blumgart anastomosis seems to be superior in terms of clinically relevant postoperative pancreatic fistula rates compared with other types of pancreato-enteric anastomosis. The advantages of robotic surgery, such as improved precision, greater control, and enhanced visualization, make robotic Blumgart anastomosis a safe, practical, and reproducible technique in the context of robotic pancreaticoduodenectomy. Conclusions: Robotic Blumgart pancreaticojejunostomy is a safe and feasible technique for pancreato-enteric anastomosis following pancreaticoduodenectomy when surgical technique is systematized step by step.

Background: Despite benefits during open pancreatoduodenectomy (PD), the artery-first approach (AFA) during minimally invasive PD (MIPD) has been poorly investigated. Methods: Data of consecutive patients undergoing MIPD (both laparoscopic (LPD) and robotic (RPD)) from 2020 to 2024 for pancreatic cancer (PC) were prospectively collected and retrospectively analyzed, comparing the surgical and oncological outcomes of LPD with right AFA and RPD with posterior AFA. The rate of ineffective AFA (IAFA), defined in the case of excessive resection time, estimated blood loss, or conversion to laparotomy, was also investigated. Results: 71 patients undergoing MIPD were selected (32 LPD and 39 RPD). Baseline patients’ characteristics only differed for a higher rate of neoadjuvant treatment in LPD and RPD groups, respectively (23.1% vs. 0%, p = 0.0036). No patients underwent conversion. R0 resection was obtained in 74.6% of patients. No difference between the groups was found regarding intraoperative, postoperative, and oncological outcomes except for a greater number of lymph nodes harvested in RPD (24 vs. 17, p = 0.023). IAFA was observed in 12.7% of patients, without difference between the groups (9.4 vs. 15.4%, p = 0.499, in LPD and RPD, respectively). Conclusions: MIPD with AFA was feasible and safe in patients affected by PC. RPD using posterior AFA had a higher number of lymph nodes retrieved when compared to LPD using right AFA. RPD has provided subjective advantages for the surgeon in terms of handling, safety, and reproducibility, although these have not translated into better outcomes. Full article

Background and Objectives: The isthmocele is a pouch-shaped defect in the anterior uterine wall, site of a previous cesarean section, due to a scar defect or dehiscence. The prevalence could be underestimated, but the rate of cesarean section is still high in the world. The preferable technique to correct this anomaly is not clearly indicated in the literature. Our objective is to evaluate the literature on the surgical treatment of isthmocele in pre-Cesarean women treated with minimally invasive technique. Our hypothesis is that robotic treatment is more effective than other procedures in women desirous of having children. Materials and Methods: The words “isthmocele”, “laparoscopy”, “robot” and “cesarean scar pregnancy” were searched on the main online scientific search sources (PubMed, Google Scholar, Scopus, WES, and Embase, etc.). We included articles in English and French, chosen for the relevance to the topic. We have decided to include also surgical corrections of isthmocele linked to pregnancies at the site of the defect, with particular attention to video training explanation. Results: We analyzed the literature about the minimally invasive surgery for the repair of an isthmocele, evaluating 20 articles. Comparing several surgical techniques, robotic-assisted laparoscopy could be an effective method to correct the defect, without high risk of intraoperative complications. Conclusions: As indicated in the literature, robotic tailored excision and repair of isthmocele (and of concomitant cesarean scar pregnancy) could be advantageous and safe, and it is necessary to promote video-training about this technique.

Background and Clinical Significance: Robotic surgery reduces the need for extensive surgical approaches and lowers perioperative complications. In particular, it offers enhanced dexterity, three-dimensional visualization, and improved precision in confined anatomical spaces. Pelvic masses pose significant challenges due to their close relationship with critical neurovascular structures, making traditional open or laparoscopic approaches more invasive and potentially riskier. Robot-assisted resection, combined with intraoperative neurophysiological monitoring, may therefore offer a safe and effective solution for the management of complex pelvic lesions. Case Presentation: An 18-year-old woman was incidentally diagnosed with an 11 cm asymptomatic pelvic mass located anterior to the sacrum. Initial differential diagnoses included neurofibroma, teratoma, and myelolipoma. Histopathological examination confirmed a ganglioneuroma. Following multidisciplinary discussion, the patient underwent a robot-assisted en bloc resection using the Da Vinci Xi multiport system. Preoperative planning was aided by 3D modeling and intraoperative navigation. Conclusions: Surgery lasted 322 min. Preoperative and postoperative eGFR values were 145.2 mL/min and 144.0 mL/min, respectively. The lesion measured 11 cm × 9 cm × 8 cm. The main intraoperative complication was a controlled breach of the iliac vein due to its close adherence to the mass. No major postoperative complications occurred (Clavien-Dindo Grade I). The drain was removed on postoperative day 3, and the bladder catheter on day 2. The patient was discharged on postoperative day 5 without further complications. Presacral ganglioneuromas are rare neoplasms in a surgically complex area. A multidisciplinary approach using robotic-assisted laparoscopy with nerve monitoring enables safe, minimally invasive resection. This strategy may help avoid open surgery and reduce the risk of neurological and vascular injury. Full article

Background: The surgical management of endometrial cancer in severely obese patients (BMI ≥ 40) presents unique challenges. This study evaluates the outcomes of various surgical approaches in terms of safety and efficacy in lymph node retrieval. Methods: A systematic review and network meta-analysis focused on intra-operative complications, post-operative complications, severe complications, and complete surgical staging rates. The analysis included 1163 patients, following a pre-specified methodology based on the PRISMA-NMA guidelines. The study was registered on PROSPERO with protocol number CRD 395959. Results: Intra-operative complications: No significant difference was found between minimally invasive surgery (MIS, 233 patients) and laparotomy (LPT) (OR 0.68 [95% CI 0.21–2.26], p = 0.18). However, robotic surgery showed a significantly lower risk (OR 0.28 [0.10–0.74]). Post-operative complications: The MIS group (457 patients) had a lower risk compared to LPT (OR 0.41 [0.26–0.64]). Network analysis: Robotic surgery had a 70.7% probability of reducing intra-operative complications compared to laparoscopy (LPS) and a 99.2% probability compared to LPT. Laparoscopy was the safest option for post-operative complications, with a 74.3% probability. Robotic surgery had an 82.4% probability of achieving complete surgical staging compared to LPT. Conclusions: Robotic surgery shows superior outcomes for complete lymph nodal staging in obese endometrial cancer patients, while LPS is favorable for post-operative complications. Further studies are needed to optimize strategies. Full article

This umbrella review synthesizes international guidelines on the surgical management of rectal cancer to provide unified recommendations tailored to local healthcare organizations. This review emphasizes the importance of surgical centralization in high-volume centers, which maximizes outcomes, reduces morbidity, and increases survival rates. Minimally invasive approaches, such as laparoscopy and robotic surgery, are highlighted for their perioperative benefits, although careful patient selection and surgical expertise are required. Mechanical bowel preparation combined with oral antibiotics is recommended to effectively reduce complications, including surgical site infections and anastomotic leakage. Enhanced Recovery After Surgery protocols have been shown to significantly improve postoperative recovery and reduce hospital stay duration. Comprehensive perioperative care, including venous thromboembolism prophylaxis and infection control, is essential for optimal patient outcomes. This review underscores the need for structured training, certification, and regular audits for advanced techniques such as robotic surgery and transanal total mesorectal excision. Implementation of a national database is recommended to support ongoing improvements in rectal cancer surgery. This review centralizes evidence-based recommendations to guide surgical decision-making and harmonize the multidisciplinary care for patients with rectal cancer. Full article

Background: Looking for anomalies and vascular control gains a central role in colon cancer surgery. Complete mesocolic excision (CME) presents technical challenges, primarily due to the considerable variability in the arterial configuration of the right colon. The importance of understanding colonic vascular anatomy has become more prominent with the adoption of this surgical technique. The aim of this study is to systematically review the vascular anatomical variations in the superior mesenteric artery (SMA) in the setting of extended lymphadenectomy for CME in right colon cancer and to show its impact in clinical practice. Methods: A systematic review of the literature on Medline (PubMed), Web of Science (WOS), and Scopus was performed according to PRISMA guidelines. The following criteria were set for inclusion: (1) studies reporting minimally invasive (robotic, laparoscopic, and hybrid techniques) or open CME/D3 lymphadenectomy; (2) studies reporting patients with right-sided colon cancer; (3) studies reporting the description or illustration of SMA variations. The methodological quality of all included studies was evaluated using the Newcastle–Ottawa Scale (NOS). Results: After the literature search, 800 studies were recorded, 31 studies underwent full-text reviews, and 9 studies met the inclusion criteria. All studies reported vascular variations in SMA, and the total number of patients was 813. No intraoperative complications were reported. In 6.4% of patients, post-operative bleeding occurred. Conclusions: Vascular anatomical variations are not a rare entity. In experienced centers, vascular anomalies are not associated with an increase in complications, both in traditional open and minimally invasive surgery (MIS). However, in MIS, full access to central vessels and intraoperative vascular control, moderate retraction, safety maneuvers, and accurate vascular dissection are mandatory. Full article

Background: Reduced-port totally robotic pancreaticoduodenectomy (rpRPD) has been introduced to address limitations of conventional robotic pancreaticoduodenectomy (cRPD), particularly regarding assistant mobility and visualization. This study aimed to evaluate the clinical feasibility and procedural consistency of rpRPD in comparison with cRPD and laparoscopic pancreaticoduodenectomy (LPD). Methods: We conducted a retrospective cohort study of patients who underwent pancreaticoduodenectomy between January 2015 and December 2024. Patients were categorized into rpRPD (n = 40), cRPD (n = 60), and LPD (n = 262) groups. Clinical outcomes and learning curves were compared using regression and cumulative sum (CUSUM) analysis. Results: Baseline characteristics were similar across groups. The rpRPD group demonstrated significantly shorter operative time (p < 0.001) and lower blood loss (p < 0.05) than cRPD, with no significant differences in postoperative complications or hospital stay. The learning curve analysis revealed that rpRPD had lower variance (5839.3 vs. 8919.1) and more stable performance than cRPD despite a slightly longer stabilization point. Lymph node retrieval was comparable across groups, supporting oncological equivalence. Conclusions: rpRPD offers comparable perioperative and oncologic outcomes to cRPD and LPD while improving operative efficiency and procedural predictability. It represents a technically feasible and safe option for minimally invasive pancreatic surgery. Full article

Despite advancements in multidisciplinary treatment, esophagectomy remains the primary curative treatment for esophageal cancer. Given that lymph node metastases can spread from the cervical to abdominal regions, three-field lymph node dissection has been established as a standard approach. However, this highly invasive procedure involves multiple anatomical regions—thoracic, abdominal, and cervical—leading to significant surgical burden. To reduce surgical invasiveness, minimally invasive esophagectomy (MIE) has become increasingly common worldwide. With its adoption and advancements in multidisciplinary therapy, discussions have emerged regarding the potential omission of lymph node dissection in selected cases. Since the introduction of robot-assisted minimally invasive esophagectomy (RAMIE) in 2004, this technique has progressively replaced conventional MIE. Robotic systems—equipped with a magnified 3D camera, articulated instruments, and tremor filtering—allow surgeons to perform complex procedures with greater precision than manual techniques. One randomized controlled trial (RCT) has demonstrated fewer postoperative complications with RAMIE compared to open esophagectomy. Additionally, RAMIE has been shown to enable more extensive lymph node dissection around the left recurrent laryngeal nerve than conventional MIE. However, the long-term oncological benefits of RAMIE remain unproven, as no RCTs have definitely confirmed its impact on long-term survival in esophageal cancer patients. Ongoing randomized trials are expected to provide further insights into its prognostic benefits. Full article
