Colorectal surgery has undergone significant advances over the past few decades, driven by the evolution of minimally invasive techniques, particularly laparoscopy and robotics. While laparoscopy is widely recognized for its short-term benefits and oncological safety, the increasing adoption of robot-assisted surgery (RAS) has generated considerable debate regarding its clinical benefits, economic implications, and overall impact on patient outcomes. This narrative review synthesizes the existing evidence, highlighting the clinical and economic aspects of RAS in colorectal surgery, while exploring areas for future research. The findings suggest that RAS offers potential technical advantages, including increased precision, three-dimensional visualization, and improved ergonomics, particularly in anatomically complex scenarios such as low rectal resections. Still, its superiority over laparoscopy remains inconclusive and current evidence is mixed. For colon cancer, meta-analyses and analyses of large cohorts suggest lower conversion rates and faster recovery with RAS, although data are mostly retrospective and lack long-term oncological endpoints. In rectal cancer, emerging evidence from randomized controlled trials demonstrates improved short-term outcomes. Additionally, the recently published three-year results of the REAL trial are the first to demonstrate enhanced oncological outcomes following RAS. However, findings remain inconsistent due to methodological heterogeneity, the absence of patient stratification, and limited data on long-term survival and cost-effectiveness. The available evidence indicates that RAS may offer advantages in selected patient populations, particularly for anatomically complex procedures. Yet, its overall utility remains uncertain. Future studies should emphasize high-quality randomized trials, stratified subgroup analyses, and standardized economic evaluations to better define the role of RAS in colorectal surgery.

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

Robot-assisted surgery has proven highly effective in the curative treatment of various gastrointestinal cancers. The advantages of robot-assisted surgery, including precision, enhanced operability, and magnified 3D visualization, allow surgeons to perform delicate procedures that would be challenging with conventional laparotomy or laparoscopy. These benefits make robot-assisted surgery a viable modality for treating various malignant tumors and an essential tool in curative surgery for solid cancers. Laparoscopic gastrectomy is currently the standard treatment for early gastric cancer, with numerous clinical trials assessing the efficacy of robot-assisted surgery. Although thoracoscopic esophagectomy has demonstrated advantages over open surgery in radical esophageal cancer treatment, ongoing studies are evaluating the noninferiority and potential benefits of robotic surgery. Robot-assisted surgery is also being explored for conversion surgery in cases where radical resection becomes feasible after multidisciplinary treatment and in polysurgery cases involving multiple prior laparotomies. However, establishing robust evidence for its efficacy in radical surgery for conversion and polysurgery cases remains a challenge. This narrative review discusses the advantages and limitations of robot-assisted surgery in such complex cases based on an analysis of the literature. Additionally, it examines the prospects of robotic-assisted surgery in polysurgery, metachronous remnant gastric cancer, and conversion surgery. Full article

Background/Objective: Sentinel lymph node (SLN) mapping is an accepted technique for the nodal staging of early-stage endometrial cancer. It is carried out commonly by minimally invasive approach, either by laparoscopy or robotics-assisted surgery. The primary aim of this study was to compare the detection rate of SLN mapping between laparoscopic and robotic surgery. Methods: A retrospective observational study including patients operated on from February 2024 to March 2025, diagnosed with endometrial cancer who underwent hysterectomy, bilateral salpingo-oophorectomy and SLN mapping. Among a total of 60 patients, 38 (63.3%) underwent laparoscopic surgery and 22 (36.7%) robotic surgery. We compared SLN detection rate and perioperative outcomes between the two routes of approach. Results: No significant differences were observed in the overall and bilateral SLN detection rate between laparoscopic and robotic surgery (97.3% and 84.2% vs. 95.5% and 91%, respectively). Significant differences were observed in operative time, with a median of 125 vs. 110 min (p = 0.004), and in hospital stay, with a median of 3 vs. 2 days (p = 0.002), with both being shorter in the robotic surgery group. No differences were observed in terms of number of SLN detected, percentage of positive nodes, intra or postoperative complications rate, or percentage of conversion to laparotomy. Conclusions: No differences were found in SLN detection rates between laparoscopic and robotic surgery. However, robotic surgery demonstrated advantages in terms of reduced operative time and shorter hospital stay. Full article

The use of ileum for ureteral reconstruction was first described in 1906. Since then, its utilization has evolved considerably. Early in the history of ileal ureters, urologists were limited by a lack of familiarity with bowel harvesting and handling. The popularization of ileal conduits for urinary diversions, however, allowed urologists to familiarize themselves with the use of ileum and paved the way for broader applications. With the emergence of laparoscopy and, later, robotic-assisted surgery, the application of ileal ureteral replacement expanded the capabilities of reconstructive urologists. This article describes the historical development of surgical techniques for ileal ureter replacement and the integration of new technologies aiding in improved outcomes, and anticipates potential future directions. In contemporary practice, robotic-assisted ileal ureteral replacement is used in cases of extensive ureteral obstruction or damage. Advantages of the robotic platform include reduced blood loss, shorter recovery time and hospital length of stay, and superior operative ergonomics. Although robotic ileal ureter replacement is a complex and challenging surgery with notable complications, studies have demonstrated the efficacy and safety of this technique in patients with an otherwise end-stage ureter. In addition, the robotic approach has provided urologists the ability to conduct complex reconstructive surgeries including bilateral ureteral replacement in conjunction with bladder augmentation or a urinary diversion. Long-term studies and continued innovation are necessary to further improve the surgical techniques, outcomes, and scope of ileal ureter reconstruction. Full article

Background: Borderline ovarian tumours (BOTs) are a unique subset of epithelial ovarian neoplasms characterised by atypical epithelial proliferation without stromal invasion. BOTs are typically diagnosed at an early stage, primarily affect women of reproductive age, and have a favourable prognosis. This study aims to evaluate the clinical characteristics, surgical management, and outcomes of BOTs in a North East London cohort. Methods: A retrospective, multicentric analysis was conducted on 69 patients with histologically confirmed BOTs managed between January 2018 and December 2022 across the Barts Health NHS Trust hospitals. Clinical and demographic data, surgical details, histopathological findings, and recurrence rates were analysed. We used descriptive and exploratory statistical methods. Results: The mean age at diagnosis was 44 years, with 46.37% under 40, including 18 nulliparous women. Most tumours (91.3%) were FIGO stage I, with mucinous histology predominating (56.52%), followed by serous BOTs (27.53%). Ultrasound and MRI demonstrated 65.45% and 81.5% sensitivities for borderline or malignant features, respectively. Surgical approaches included open surgery (75.4%), laparoscopy (17.4%), and robotic-assisted procedures (2.9%). Fertility-sparing surgery (FSS) was performed in all nulliparous women under 40 years of age. Recurrence occurred in 2 cases, both in patients with prior FSS performed over a decade earlier. Conclusions: FSS is a viable option for young women, especially if nulliparous and under the age of 40, with recurrence rates comparable to radical procedures. Most patients were diagnosed early (FIGO I) with excellent prognoses. MRI proved most sensitive for diagnosis, while long-term follow-up with transvaginal ultrasound and CA-125 monitoring is crucial for detecting recurrences. Full article

Background/Objectives: The aim of the study was to compare the perioperative and oncologic outcomes of patients who underwent surgery for colorectal cancer (CRC) performed using laparoscopy or using the Medtronic Hugo™ Robotic-Assisted Surgery (RAS) system. Methods: This is a retrospective comparative single-center study of consecutive minimally invasive surgeries for CRC performed by two colorectal surgeons with extensive laparoscopic experience at the beginning of their robotic expertise. Patients were not selected for the surgical approach, but waiting lists and operating room availability determined whether the patients were in the robotic group or the laparoscopic group. The primary outcome was to compare 30-day postoperative complications according to the Clavien–Dindo classification and the Complication Comprehensive Index (CCI). The secondary outcomes included operating times, conversion rates, intraoperative complications, length of hospital stays (LOS), readmission rates, and short-term oncologic outcomes, such as the R0 resection, the number of lymph nodes harvested, the total mesorectal excision (TME) quality, and the circumferential resection margin (CRM). Results: Of the 109 patients, 52 underwent robotic and 57 laparoscopic CRC surgery. Patient demographic and clinical characteristics were similar in the two groups. There was no significant difference between the robotic and the laparoscopic groups regarding postoperative complications, the Clavien–Dindo classification, and the CCI. They also had similar operating times, conversion rates, intraoperative complications, LOSs, readmission rates, and short-term oncologic outcomes (the lymph nodes harvested, the R0 resection, TME quality, and CRM status). Conclusions: This study reports the largest cohort of CRC surgery performed using the Medtronic Hugo™ RAS system and is the first comparative study with laparoscopy. The perioperative and oncologic outcomes were similar, demonstrating that the Medtronic Hugo™ RAS system is safe and feasible for CRC as compared to laparoscopic surgery, even at the beginning of the robotic experience.

Over the past two decades, surgical techniques in colorectal cancer (CRC) have improved patient outcomes through precision and reduced invasiveness. Open colectomy, laparoscopic surgery, robotic-assisted procedures, and advanced rectal cancer treatments such as total mesorectal excision (TME) and transanal TME are discussed in this article. Traditional open colectomy offers reliable resection but takes longer to recover. Laparoscopic surgery transformed CRC care by improving oncological outcomes, postoperative pain, and recovery. Automated surgery improves laparoscopy’s dexterity, precision, and 3D visualisation, making it ideal for rectal cancer pelvic dissections. TME is the gold standard treatment for rectal cancer, minimising local recurrence, while TaTME improves access for low-lying tumours, preserving the sphincter. In metastatic CRC, palliative procedures help manage blockage, perforation, and bleeding. Clinical examples and landmark trials show each technique’s efficacy in personalised care. Advanced surgical techniques and multidisciplinary approaches have improved CRC survival and quality of life. Advances in CRC treatment require creativity and customised surgery. Full article

Background/Objectives: Robotic-assisted surgery is an attractive and promising option with unique advantages in rectal cancer surgery, but the optimal surgical approach is still debatable. Therefore, we aimed to compare the short- and long-term outcomes of the robotic-assisted approach with the laparoscopic-assisted and open approaches. Methods: A single referral center in Israel retrospectively reviewed all patients that underwent an elective rectal resection for primary non-metastatic rectal cancer between 2010 and 2020. The cohort was separated into three groups according to the surgical approach: robotic, laparoscopic, or open. Results: The cohort included 526 patients with a median age of 64 years (range 31–89), of whom 103 patients were in the robotic group, 144 in the open group, and 279 patients in the laparoscopic group. The robotic group had significantly more lower rectal tumors (24.3% versus 12.7% and 6%, respectively, p < 0.001), more locally advanced tumors (65.6% versus 51.2% and 50.2%, respectively, p = 0.004), and higher rates of neoadjuvant radiotherapy (70.9% versus 54.2% and 39.5%, respectively, p < 0.001). Conversion to an open laparotomy was more common in the laparoscopy group (23.1% versus 6.8%, respectively, p = 0.001). The open approach had higher rates of intraoperative complications (23.2% compared with 10.7% and 13.5% in the robotic and laparoscopic groups, respectively, p = 0.011), longer hospital stays (10 days compared with 7 and 8 days, respectively, p < 0.001), and higher rates of postoperative complications (76% compared with 68.9% and 59.1%, respectively, p = 0.002). The groups were similar in the number of harvested lymph nodes (14) and the incidence of positive resection margins (2.1%). The 5-year overall survival in the robotic group was 92.3% compared with 90.5% and 88.3% in the laparoscopic and open groups, respectively (p = 0.12). The 5-year disease-free survival in the robotic group was 68% compared with 71% and 63%, respectively (p = 0.2). Conclusions: The robotic, laparoscopic, and open approaches had similar histopathological outcomes and long-term oncological outcomes. The open approach was associated with higher rates of perioperative morbidity. These findings suggest that the robotic approach is safe and effective in rectal cancer surgery. Full article

Background: Advanced epithelial ovarian cancer (EOC) has traditionally been treated with primary debulking surgery; however, recent phase III trials have demonstrated similar survival outcomes for patients who were randomized to neoadjuvant chemotherapy followed by interval debulking (IDS) when compared to patients who underwent PDS. Methods: We sought to evaluate a cohort of patients with EOC diagnosed between 2010 and 2019 who underwent complete cytoreduction (R0—no gross residual disease) during IDS. We compared the outcomes after R0 resection via MIS versus laparotomy in IDS. The primary endpoint was overall survival (OS). Kaplan-Meier analysis and inverse probability of treatment weighting (IPTW) were used. Cases were stratified by surgical extent and within the MIS cohort by robotic assistance. Surgical outcomes (LOS, readmission rate, 30- and 90-day mortality) were also assessed. Results: In total, 2412 patients were eligible. 624 (25.8%) underwent R0 resection via MIS. Over the study period, the MIS utilization rate increased from 12% to 36%. There was no significant difference in OS between the MIS and open cohorts (51 vs. 46 months, HR 1.1; 95% CI 0.96–1.24). 30-day and 90-day postoperative mortality rates were higher in the open group (1.6% vs. 0.8%, p = 0.006) and (1.9% vs. 3.5%, p = 0.003), respectively. Patients in the MIS group were less likely to undergo extensive surgery (41% vs. 53%, p < 0.001). When stratified by surgical extent, no significant difference in OS was observed between MIS and laparotomy (49 vs. 44 months in the extensive surgery group and 53 vs. 50 months in the non-extensive surgery group). Within the MIS cohort, 49% of cases were performed robotically. OS did not differ significantly between robotic and conventional laparoscopic cases (52 vs. 50 months). From 2010 to 2019, there was an increase in the use of robot-assisted laparoscopy (from 6.2% to 25.5%), coinciding with a decline in the laparotomy rate (from 88.1% to 63.5%) (p = 0.008). Conclusions: R0 resection via MIS during IDS showed similar OS and decreased postoperative mortality compared to laparotomy. The increasing utilization of robotic assistance is associated with a decrease in the laparotomy rate. Full article

Renal masses are uncommon during pregnancy; they represent the most frequently encountered urological cancer in pregnant patients and require careful surgical planning. The introduction of robotic surgical systems aims to address these challenges by simplifying intra-corporeal suturing and reducing technical complexity. Robot-assisted laparoscopic renal surgery offers potential benefits over both open surgery and conventional laparoscopy, providing greater precision and reduced invasiveness, particularly in tumor excision and suturing. Although urological tumors during pregnancy are rare, early detection significantly improves outcomes by enabling intervention before the tumor advances and while the uterus remains relatively small. The decision regarding the timing and necessity of surgery in pregnant patients requires a careful assessment of maternal health, fetal development, and the progression of the disease. Risks for adverse pregnancy outcomes should be explained, and the patient’s decision about pregnancy termination should be considered. Radical nephrectomy or nephron-sparing surgery are essential treatments for the management of renal tumors. Effective management demands close collaboration between a multidisciplinary team and the patient to ensure individualized care. The aim of this review was to evaluate the renal tumors during pregnancy in terms of epidemiology, risk factors, diagnosis and the safety of a robot-assisted laparoscopic approach in the management of these tumors.

Image-based 3D reconstruction enables robot-assisted interventions and image-guided navigation, which are emerging technologies in laparoscopy. When a robotic arm guides a laparoscope for image acquisition, hand–eye calibration is required to know the transformation between the camera and the robot flange. The calibration procedure is complex and must be conducted after each intervention (when the laparoscope is dismounted for cleaning). In the field, the surgeons and their assistants cannot be expected to do so. Thus, our approach is a procedure for a robot-based multi-view 3D reconstruction without hand–eye calibration, but with pose optimization algorithms instead. In this work, a robotic arm and a stereo laparoscope build the experimental setup. The procedure includes the stereo matching algorithm Semi Global Matching from OpenCV for depth measurement and the multiscale color iterative closest point algorithm from Open3D (v0.19), along with the multiway registration algorithm using a pose graph from Open3D (v0.19) for pose optimization. The procedure is evaluated quantitatively and qualitatively on ex vivo organs. The results are a low root mean squared error (1.1–3.37 mm) and dense point clouds. The proposed procedure leads to a plausible 3D model, and there is no need for complex hand–eye calibration, as this step can be compensated for by pose optimization algorithms. Full article

Background and Objectives: Robotic-assisted laparoscopy (RS) has been widely adopted for the management of endometrial cancer (EC) due to favorable perioperative outcomes, especially in the context of obesity, which is an established risk factor for EC. This study retrospectively evaluated the perioperative outcomes of RS versus conventional laparoscopy (LS) in treating EC and atypical endometrial hyperplasia (AH). Methods: Between November 2021 and October 2023, 138 patients with AH or EC underwent surgery at the Clinic of Obstetric and Gynecological—Azienda Sanitaria Universitaria Friuli Centrale, Udine. All patients had total hysterectomy with bilateral salpingo-oophorectomy, with or without lymphadenectomy or sentinel lymph node biopsy. The study included 62 patients treated with LS and 62 with RS. Results: The median BMI was higher in the RS group (35.5 vs. 24 kg/m², p = 0.001). There was no significant difference in operative time between the laparoscopic group and the robotic console time (median 130 vs. 130 min, p = 0.131). No significant differences were found in terms of blood loss, conversion to laparotomy, intraoperative complications, hospital stay, or early postoperative complications between the two groups. Conclusions: Our data confirm the feasibility of robotic surgery in obese patients, allowing surgical results comparable to those of laparoscopy in normal-weight patients. Full article

Objective: This study aimed to assess the impact of minimally invasive surgery (MIS) on survival rates in women diagnosed with endometrial cancer (EC). Methods: A retrospective cohort of 723 women who underwent MIS for EC was analyzed, with 468 having conventional laparoscopy (LPS) and 255 undergoing robotic-assisted laparoscopy (RAL). Sociodemographic features, tumor characteristics, and survival rates were examined for the entire cohort and in a propensity score-matched model. Results: In the overall sample, women who underwent RAL were older, had higher BMI, more comorbidities, and more aggressive tumors. After matching for age, BMI, comorbidities, ASA score, histological type, grade, myometrial invasion, LVSI, and FIGO stage, 482 patients (241 matched pairs) were selected. Disease-free survival (DFS) HR: 1, overall survival (OS) HR: 0.9, and specific survival related to EC (SS) HR: 0.15 were similar between the LPS and RAL groups. Conclusions: These findings suggest that the choice of surgical approach (robotic or laparoscopic) does not impact survival outcomes when matched in homogeneous groups. Full article
