RESUMO
BACKGROUND: The article describes our initial experience using CMR Versius platform for several procedures in general surgery. METHODS: Between September 2022 and April 2023, seventy patients underwent robotic surgery in a multi-robotic referral center (San Paolo University Hospital, Milan, Italy). Three surgeons with only laparoscopic experience performed 24 cholecystectomies, 13 inguinal hernia repairs, 9 ventral hernia repairs, 7 right hemicolectomies, 11 left hemicolectomies, 1 sigmoidectomy, 1 ileocecal resection, 1 ventral rectopexy, 1 Nissen fundoplication, 1 total splenectomy, and 1 exploration with multiple biopsies. RESULTS: All surgeries were full-robotic, with only one conversion to laparoscopy. The short length of stay and low rate of severe morbidity are promising findings. Although operative time was lengthened, clinical outcomes were not affected. CONCLUSIONS: Our experience demonstrates that the adoption of Versius system is safe and feasible in general surgery. The standardization of port placement and BSU set-up can certainly reduce the operative time.

BACKGROUND: The aim of the present study is to compare outcomes of the robotic hand-sewn, linear- and circular-stapled techniques performed to create an intrathoracic esophagogastric anastomosis in patients who underwent Ivor-Lewis esophagectomy. METHODS: Patients who underwent a planned Ivor-Lewis esophagectomy were retrospectively analysed from prospectively maintained databases. Only patients who underwent a robotic thoracic approach with the creation of an intrathoracic esophagogastric anastomosis were included in the study. Patients were divided into three groups: hand-sewn-, circular stapled-, and linear-stapled anastomosis group. Demographic information and surgery-related data were extracted. The primary outcome was the rate of anastomotic leakages (AL) in the three groups. Moreover, the rate of grade A, B and C anastomotic leakage were evaluated. In addition, patients of each group were divided in subgroups according to the characteristics of anastomotic fashioning technique. RESULTS: Two hundred and thirty patients were enrolled in the study. No significant differences were found between the three groups about AL rate (p = 0.137). Considering the management of the AL for each of the three groups, no significant differences were found. Evaluating the correlation between AL rate and the characteristics of anastomotic fashioning technique, no significant differences were found. CONCLUSIONS: No standardized anastomotic fashioning technique has yet been generally accepted. This study could be considered a call to perform ad hoc high-quality studies involving high-volume centers for upper gastrointestinal surgery to evaluate what is the most advantageous anastomotic technique.

BACKGROUND: Since the introduction of minimally invasive surgery, new techniques like transabdominal preperitoneal (TAPP) repair have progressively gained acceptance for the treatment of groin hernia. Laparoscopic TAPP (LTAPP) is recommended for bilateral repairs. Likewise, the introduction of robotic platforms has promised additional surgical benefits for robotic TAPP (RTAPP), which are yet to be confirmed. This study compared multicenter data obtained from patients undergoing bilateral inguinal hernia repair with RTAPP, performed during the preliminary learning curve period, versus conventional LTAPP. MATERIALS AND METHODS: All consecutive bilateral inguinal hernia patients from four Italian centers between June 2015 and July 2020 were selected. A propensity score model was used to compare patients treated with LTAPP versus RTAPP, considering sex, age, body mass index, current smoking status, overall comorbidity, hernia classification (primary or recurrent), and associated procedures as covariates. After matching, intraoperative details and postoperative outcomes were evaluated. RESULTS: In total, 275 LTAPP and 40 RTAPP were performed. After matching, 80 and 40 patients were allocated to the LTAPP and RTAPP cohorts, respectively. No intraoperative complications or conversion to open surgery occurred. However, a longer operative time was recorded in the RTAPP group (79 ± 21 versus 98 ± 29 min; p < 0.001). Postoperative visual analog scale (VAS) pain scores (p = 0.13) did not differ and complication rates were similar. There were no clinical recurrences in either group, with mean follow-up periods of 52 ± 14 (LTAPP) and 35 ± 8 (RTAPP) months. A statistical difference in length of hospital stay was found between the groups (1.05 ± 0.22 vs 1.50 ± 0.74 days; p < 0.001). CONCLUSION: In this patient population, outcomes for bilateral inguinal hernia repair appear comparable for RTAPP and LTAPP, except for a shorter recovery after laparoscopic surgery. A longer operative time for robotic surgery could be attributable to the learning curve period of each center.

BACKGROUND: Surgeons can minimize the risk of bile duct injury (BDI) during challenging mini-invasive cholecystectomy through technical standardization by means of a precise anatomical landmark identification (Critical View of Safety) and advanced technology for biliary visualization. Among these systems, the adoption of magnified stereoscopic 3-dimensional view provided by robotic platforms and near infrared fluorescent cholangiography (NIRF-C) is the most promising. METHODS: In this prospective cohort study, we evaluated all consecutive minimally invasive cholecystectomies (laparoscopic and robotic) performed with NIRF-C between May 2022 and January 2023 at General Surgery Unit, Department of Health Sciences, University of Milan, San Paolo Hospital (Milan, Italy). Inclusions criteria were as follows: (1) acute cholecystitis (emergency group), (2) history of chronic cholecystitis or complicated cholelithiasis (deferred urgent group), (3) difficult cases (patients affected by cirrhosis, with scleroatrophic gallbladder or BMI > 35 kg/m2). For each group, the detection rate and visualization order of the main biliary structures were reported (cystic duct, CD; common hepatic duct, CHD; common bile duct, CBD; and CD-CHD junction). RESULTS: A total of 101 consecutive patients were enrolled, including 83 laparoscopic and 18 robotic cholecystectomies. All patients were stratified into three subgroups: (a) emergency group (n = 33, 32.7%), (b) deferred urgent group (n = 46, 45.5%), (c) difficult group (n = 22, 21.8%). Visualization of at least one biliary structure was possible in 94.1% of cases (95/101). Interestingly, all four main structures were detected in 43.6% of cases (44/101). The CD was the structure identified most frequently, being recognized in 91/101 patients (90.1%), followed by CBD (83.2%), CHD (62.4%), and CD-CHD junction (52.5%). In the subset of patients that underwent emergency surgery for AC, the CD-CHD confluence was identified in only 45.5% of cases. However, early and precise identification of CBD (75.8%) and CD (87.9%) allowed safe isolation, clipping, and transection of the cystic duct. In the deferred urgent group, the CBD and the CD were easily identified as first structure in a high percentage of cases (65.2% and 41.3% respectively), whereas the CD-CHD junction was the third structure to be identified in 67.4% of cases, the highest value among the three subgroups. In the difficult group, NIRF-C did not prove to be a useful tool for biliary visualization. The rates of failure of visualization were elevated: CBD (27.3%), CD (18.2%), CHD (54.5%), and CD-CHD (68.2%). CONCLUSIONS: NIRF-C is a powerful real-time diagnostic tool to detect CBD and CD during minimally invasive cholecystectomy, especially when inflammation due to acute or chronic cholecystitis subverted the anatomy of the hepatoduodenal ligament.

PURPOSE: Robotic surgery offers new possibilities in repairing complex hernias with a minimally invasive approach. This study aimed to analyze our preliminary results. METHODS: Between November 2015 and February 2020, 150 patients underwent robotic reconstruction for abdominal wall defects (77 primary and 73 incisional). A retrospective analysis of a prospectively maintained database was conducted to evaluate the short-term outcomes. RESULTS: The mean operative time was 176.9 ± 72.1 min. No conversion to open or laparoscopic approach occurred. The mean hospital length of stay was 2.6 ± 1.6. According to Clavien-Dindo classification, two (grade III) complications following retromuscular mesh placement (1.3%) occurred. One patient (0.7%) required surgical revision due to small bowel occlusion following an intraparietal hernia. The 30-day readmission rate was 0.6%, and the mortality was nihil. CONCLUSIONS: Robotic surgery is valuable for safely completing challenging surgical procedures like complex abdominal wall reconstruction, with low conversion and complication rates. A stepwise approach to the different surgical techniques is essential to optimize the outcomes and maximize the benefits of the robotic approach.

RESUMO
BACKGROUND: During the past decade, the concept of complete mesocolic excision (CME) has emerged as a possible strategy to minimize recurrence for right colon cancers. The purpose of this study was to compare robotic versus laparoscopic CME in performing right colectomy for cancer. METHODS: Pertinent data of all patients who underwent robotic or laparoscopic right colectomy with CME using a Pfannenstiel incision and intracorporeal anastomosis performed between October 2005 and November 2015 were entered in a prospectively maintained database. RESULTS: A total of 202 patients underwent robotic (n = 101) or laparoscopic (n = 101) right colectomy within the study period. Patient characteristics were equivalent between groups. The robotic group showed a statistically significant reduction in conversion rate (0% vs. 6.9%, p = 0.01) but a longer operative time (279 min vs. 236 min, p < 0.001) compared with the laparoscopic group. There were no other differences in perioperative clinical or pathological outcomes. Five-years overall survival was 77 versus 73 months for the robotic versus laparoscopic groups (p = 0.64). The disease-free survival (DFS) rates were 85% and 83% for the robotic versus laparoscopic groups (p = 0.58). Among UICC stage III patients, there was a slight but not significant difference in 5-year DFS for the robotic group (81 vs. 68 months; p = 0.122). CONCLUSIONS: Both approaches for right colectomy with CME were safe and feasible and resulted in excellent survival. Robotic assistance was beneficial for performing intracorporeal anastomosis and dissection as evidenced by the lower conversion rates. Further robotic experience may shorten the operative time.

BACKGROUND: A modified complete mesocolic excision (mCME) technique for the treatment of right-sided colon cancer recently was shown by Hohenberger and colleagues to provide impressive long-term oncologic outcomes. This report aims to describe the authors' experience with robotic right colectomy using mCME. The safety, feasibility, and efficacy of this procedure are measured by complications, conversion rates, and 4-year oncologic outcomes. METHODS: A retrospective study analyzed 100 consecutive patients who underwent robotic right colectomy with mCME and intracorporeal anastomosis at the authors' institution between November 2005 and November 2013. Intra- and postoperative clinical outcomes, pathologic data, and survival were analyzed. RESULTS: Robotic right colectomy with mCME was successfully performed for all the patients. No conversions or intraoperative complications occurred. The major complication rate (Dindo 3 or 4) was 4 %. During a median follow-up period of 48.5 months (range 24-114 months), the survival rates were 94.5 % for disease-specific survival, 91.4 % for disease-free survival, and 90.3 % for overall survival. CONCLUSIONS: The authors' experience confirms the feasibility and safety of mCME for the treatment of right-sided colon cancer. This technique provided satisfying short-term outcomes with promising 4-year oncologic results. However, the real benefits of the CME technique should be evaluated further by well-conducted randomized studies before its adoption in routine practice is recommended.

Treatment of incisional hernia is a rapidly evolving field of surgery, with actual trends being oriented toward retromuscular/preperitoneal mesh placement. The diffusion of robotic surgery is constantly growing in different surgical specialties and is gaining widespread acceptance for abdominal wall reconstruction. Recently, novel robotic platforms have entered into the market. In this study, we present the first transabdominal retromuscular incisional hernia repair performed with the new Hugo RAS™ system (Medtronic, Minneapolis, MN, USA). The surgical team had previous robotic experience and completed an official 2-day session running incisional hernia repair on human cadaver lab. Operating room setting and trocar layout were planned. The patient presented a 4 × 4 cm midline incisional hernia and was scheduled for transabdominal retromuscular incisional hernia repair at our Institution. A description of the operative room setup, robotic arm configuration and docking/tilt angles is provided. Docking time, operative time, and console time were 15, 95, and 75 min, respectively. All the surgical steps were completed without critical surgical errors or high-priority alarms. Neither intraoperative complications nor conversion to open surgery was recorded. Postoperative course was uneventful and the patient was discharged on postoperative day 2. The safety and the feasibility of these procedures will require further analysis and larger patients' sample sizes for procedural standardization and potential integration into minimally invasive abdominal wall reconstruction programs.
RESUMO
The diffusion of robotic surgery is rapidly and constantly growing in different surgical specialties. Recently, novel robotic platforms have entered into the market. To date, however, most of the reports on their clinical use have specifically focused on gynecological and urological surgery. In this study, we present the first three robotic-assisted colectomies performed with the new Hugo RAS system (Medtronic, Minneapolis, MN, USA). The surgical team had previous robotic experience and completed simulation training and an official 2-day cadaver laboratory session. Operating room setting and trocar layout were planned and two full cadaver procedures were carried out (right and left colectomy). Onsite dry-run sessions were performed before tackling clinical cases. Three patients underwent robotic-assisted colectomies: one left colectomy, two right colectomies with complete mesocolic excision (CME) and high vascular ligation (HVL) at our Institution. Preoperative diagnosis was colonic adenocarcinoma in all cases. A description of the operative room setup, robotic arm configuration and docking angles is provided. Mean docking time and console time were 8 and 259 min, respectively. All the surgical steps were completed without critical surgical errors or high-priority alarms. Neither intraoperative complications nor conversions to open surgery were recorded. Postoperative courses were uneventful with a mean length of stay of 5 days. Further clinical data and experience are required for procedural standardization and potential integration of the system into robotic general surgery and colorectal programs.

Endometriosis is a benign gynecological disease characterized by the presence of endometrial tissue outside the uterus. The eradication of non-gynecological localizations represents the real surgical challenge. A 29-year-old woman underwent robotic surgery with the Da Vinci system (Intuitive Surgical Inc.) for a diagnosis of stage IV deep endometriosis. The patient presented with 5 cm left ovarian endometrioma, an infiltration of the left posterior parametrium, and bilateral ureteral endometriosis. Once inside the pelvic cavity, deep intestinal infiltrating endometriosis implants were confirmed as triple, multicentric, and multifocal lesions, affected distal sigmoid, rectosigmoid junction, and upper rectum. An expert multiple excision, sparing the intestinal mucosa, was performed. To our knowledge, this is the first description of a multiple robotic shaving of multicentric endometriotic intestinal lesions. After the surgery, a normal diet was quickly restored, accelerating the recovery of the physiological peristalsis and the overall recovery time.
RESUMO
Robotic surgery may offer significant advantages for treating extraperitoneal rectal cancer. Although laparoscopy has been shown to be safe and effective, laparoscopic total mesorectal excision (TME) remains technically challenging and is still performed in selected centers. Robotic anterior resection (RAR) may overcome the drawback of conventional laparoscopy, providing high-quality surgery with favorable oncological outcomes. Moreover, recent data show how RAR offers clinical and oncological benefits when affording difficult TMEs, such as low and advanced rectal tumors, in terms of complication rate, specimen quality, recurrence rate, and survival. This series aims to review the most recent and relevant literature, reporting mid- and long-term oncological outcomes and focusing on minimally invasive RAR for low rectal cancer.
RESUMO
Introduction: Inguinal hernia repair is one of the most commonly performed surgical procedures in general surgery. Despite surgical advances, recurrence and chronic pain are still major issues after this intervention. Aim of our study was to retrospectively assess and compare outcomes of robotic versus laparoscopic repair of recurrent inguinal hernia. Methods: All patients who underwent recurrent inguinal hernia repair between 2014 and 2021 in five different institutions were included in our study. Baseline data on age, gender, body mass index, comorbidities, smoking habit, and anticoagulant therapy were retrospectively collected from prospectively maintained databases. Operative time, length of stay, and early and late complications were compared between the robotic and the laparoscopic approach. Results: Forty-eight patients underwent recurrent inguinal hernia repair between January 2014 and December 2021. Twenty-three patients underwent a robotic procedure, whereas 25 were submitted to the laparoscopic intervention. Overall mean follow-up was 26.2 months. There was no significant difference in the baseline characteristics of the two groups. Acceptable and comparable rates of peri- and postoperative outcomes were recorded. However, postoperative visual analog scale score and incidence of chronic pain were lower after the robotic rather than after the laparoscopic approach. (2.9 versus 3.8 P = .002; 20% versus 0%; P = .02, respectively). Conclusions: Minimally invasive repair of recurrent inguinal hernia is safe and feasible; robotic surgery is associated with low rate of postoperative and chronic pain without a significant increase in operative time.

The Hugo RAS and Versius are new robotic systems with a multimodular configuration, requiring a dedicated positioning of units, arms and trocars. While promising flexibility and multiquadrant opportunities-with an enhanced range of motion-the presence of multiple units around the patient should be effectively managed by the assistant and requires a new background of tasks. The article represents a practical guide while providing an overview on assistants' perspectives.

The scenario of robotic surgery is rapidly evolving with the introduction of new robotic systems. A structured learning program in robotic surgery during academic education is often lacking, especially for undergraduates; as a result, many students may be unaware of indications to robotic surgery and technological progress. The aim of the study is to evaluate the knowledge and interest toward robotic surgery of medical and nurse students, and to analyze how the attractiveness may change after a hand-on training course with new simulators of Hugo RAS and Versius System. We performed a cross-sectional study involving medical and nurse students recruited on a voluntary basis at ASST Santi Paolo and Carlo, Milan; participants were invited to join a hands-on practice simulation with the Hugo RAS and/or Versius Trainer Simulator. Before the hand-on exercise, students were asked to fulfill an online anonymous questionnaire addressing knowledge and interest toward robotic surgery. After a 2-h hands-on exercises at the Hugo RAS and/or at the Versius Trainer simulator (preceded by a brief lecture on robotic surgery and new systems), participants were asked to complete a second-round questionnaire to evaluate changes in attractiveness toward robotic surgery. Data were recorded in a database; after a descriptive analysis of the variables, median values were compared with the Mann-Whitney U test, frequencies with the Fisher's exact test and in the case of paired observations (before and after the simulation), the Mc Nemar test was used. Forty-one undergraduates agreed to participate. Twenty-three nursing students and 18 medical students were recruited. Some of them had a basic knowledge in robotic surgery and were able to figure out some surgical indications, given the presence of a robotic program already settled up at the institution. Before the hands-on course, 44.0% nurse students and 36.6% of medical students were interested in surgical disciplines and robotic surgery. After the simulation, all students (100%) reported a high level of interest in robotic surgery and some of them required for a dedicated internship (p < 0.001). The students provided also feedback on the perceived ease-of-use of the robotic simulators (on a scale 0-10); overall, the median score was 8, IQR [7-8], with no differences between nursing and medical students (p = 0.482). In conclusion, the study demonstrates a great interest toward robotic surgery as a part of medical and nurse education. A hands-on simulation further improved the interest of undergraduates from both backgrounds. The technological progress with the availability of new surgical systems will be the future challenge of training programs and should be considered at all levels of education.

Background: Robot-assisted surgery ensures minimal invasiveness; since the expiry of the Da Vinci patent, new robotic systems have entered the market. Recently, the Hugo RAS received CE approval for several surgical procedures. However, more is needed to know about skill acquisition at the new simulator. Objective: This study aims to analyse the factors impacting basic surgical skills at the Hugo RAS simulator. Design setting and participants: We present a cross-sectional study involving 71 participants of different backgrounds invited to a hands-on session with the Hugo RAS simulator voluntarily. All of them had no prior expertise with the system. Participants were recruited among medical/nurse students, residents, and laparoscopic and robotic surgeons. Intervention: All participants underwent a hands-on "pick and place" exercise at the Hugo RAS simulator; the metrics of a second-round pick and place exercise were recorded. Outcome measurements and statistical analysis: Metrics were analysed with regard to the following variables: demographics, videogame use, and prior surgical experience (no surgical expertise, experience with laparoscopy, and experience with robotic console). Results and limitations: All participants completed the test. Of them, 77.5% were naïve to surgery, 8.5% had prior laparoscopic expertise, and 14.1% had prior robotic console experience. The time to complete the pick and place exercise was significantly lower (p < 0.001) among prior robotic surgeons (38 s, interquartile range [IQR] 34-45) compared with both naïve participants (61 s, IQR 53-71) and laparoscopists (93 s, IQR 53-162). The overall score of the exercise decreased with age (p = 0.046); however, the overall scores were significantly and steadily higher among surgeons experienced in robotic consoles across all age groups (p = 0.006). Neither gender (p = 0.7) nor videogame use (p = 0.9) correlated significantly with the metrics. Conclusions: This is the first study analysing factors impacting basic skill acquisition at a new robotic simulator. Experience with robotic consoles may represent a major factor, raising the hypothesis of the transferability of basic robotic skills across different robotic systems. Further studies are required to explore this issue. Patient summary: In the present study, we analysed which characteristics may affect the basic surgical skills at a novel robotic platform.
RESUMO
BACKGROUND: Robotic surgery may facilitate complex procedures such as right colectomy with complete mesocolic excision (CME) and shorten the learning curve. This study aimed to compare senior and junior surgeons' results in performing robotic right colectomy (RRC) with CME and intracorporeal anastomosis for right colon cancer. MATERIALS AND METHODS: Between January 2015 and April 2020, a total of 161 patients underwent RRC with CME. After propensity score matching, two groups of 31 patients for each surgeon were formed. Intraoperative, postoperative and pathological outcomes were the variables assessed. RESULTS: No statistically significant difference was recorded between the two groups. The senior surgeon experienced 16.1% minor complications (Clavien-Dindo I-II) and 3.2% major complications (Clavien-Dindo III-IV), while the novice surgeon reported 19.3% and 3.2% rates of minor and major adverse events, respectively. CONCLUSIONS: After a structured training protocol, a novice may obtain comparable results to an expert in performing RRC with CME.

Despite the well-known benefits of the minimally invasive approach for the right colon cancer treatment, less is known about its feasibility and advantages in morbid obese patients. The aim of this study is to compare the postoperative outcomes after totally minimally invasive right colectomy between the obese and non-obese population. Data derived from a prospectively maintained multicenter colorectal database were analysed, dividing the enrolled patients into two groups: obese (BMI > 29.99) patient group and non-obese patient group. Data about gender, age, American Society of Anesthesiologists (ASA) Score, tumor characteristics, operative time, anastomosis time, extraction site, incision length, intraoperative complications, postoperative complications, postoperative recovery, specimen length and retrieved nodes were taken to assess the achievement of the oncologic standards. After a propensity score matching, a total of 184 patients was included, 92 in each group. No differences were found in terms of demographic data and tumor characteristics. Intraoperative data showed a significant difference in terms of anastomosis time in favour of non-obese group (p < 0.0001). No intraoperative complications were recorded and no conversion was needed in both groups. No differences were found in terms of postoperative complications. There were no differences in terms of first mobilization (p = 0.745), time to first flatus (p = 0.241) time to tolerance to liquid and solid diet (p = 0.241 and p = 0.06) and length of hospital stay (p = 0.817). The analysis of oncologic outcomes demonstrated adequate results in both groups. The results obtained by our study confirmed the feasibility and safety of the totally minimally invasive approach even in obese population.
