RESUMEN
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.
RESUMEN
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: 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.

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.
RESUMEN
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.
RESUMEN
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.

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: 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.

The minimally invasive treatment of rectal cancer with Total Mesorectal Excision is a complex and challenging procedure due to technical and anatomical issues which could impair postoperative, oncological and functional outcomes, especially in a defined subgroup of patients. The results from recent randomized controlled trials comparing laparoscopic versus open surgery are still conflicting and trans-anal bottom-up approaches have recently been developed. Robotic surgery represents the latest consistent innovation in the field of minimally invasive surgery that may potentially overcome the technical limitations of conventional laparoscopy thanks to an enhanced dexterity, especially in deep narrow operative fields such as the pelvis. Results from population-based multicenter studies have shown the potential advantages of robotic surgery when compared to its laparoscopic counterpart in terms of reduced conversions, complication rates and length of stay. Costs, often advocated as one of the main drawbacks of robotic surgery, should be thoroughly evaluated including both the direct and indirect costs, with the latter having the potential of counterbalancing the excess of expenditure directly related to the purchase and maintenance of robotic equipment. Further prospectively maintained or randomized data are still required to better delineate the advantages of the robotic platform, especially in the subset of most complex and technically challenging patients from both an anatomical and oncological standpoint.
RESUMEN
Rectal prolapse is a condition that can cause significant social impairment and negatively affects quality of life. Surgery is the mainstay of treatment, with the aim of restoring the anatomy and correcting the associated functional disorders. During recent decades, laparoscopic abdominal procedures have emerged as effective tools for the treatment of rectal prolapse, with the advantages of faster recovery, lower morbidity, and shorter length of stay. Robotic surgery represents the latest evolution in the field of minimally invasive surgery, with the benefits of enhanced dexterity in deep narrow fields such as the pelvis, and may potentially overcome the technical limitations of conventional laparoscopy. Robotic surgery for the treatment of rectal prolapse is feasible and safe. It could reduce complication rates and length of hospital stay, as well as shorten the learning curve, when compared to conventional laparoscopy. Further prospectively maintained or randomized data are still required on long-term functional outcomes and recurrence rates.
RESUMEN
Technical and oncological aspects are still debated when dealing with minimally-invasive right colectomy. Main controversial issues still remain about whether the anastomosis should be performed intra- or extracorporeally and if a complete mesocolic excision (CME) should be carried out. We report the feasibility of robotic right colectomy with CME and intracorporeal anastomosis (IA) for right sided colon cancer. Data from patients who underwent robotic right colectomy with IA and CME from January 2015 to April 2020 were prospectively collected and retrospectively analyzed. Intraoperative outcomes and complications (minor I-II and major III-IV according to Clavien-Dindo classification), conversion rate, 30-day postoperative outcomes and pathological outcomes were the variables assessed. A total of 161 patients undergoing robotic right colectomy for cancer met the inclusion criteria. Mean operative time was 185 min, no intraoperative complications were observed, and the conversion rate was 3.7% (6 patients requiring elective conversions). Overall, mean postoperative stay was 4.9 days and the overall 30-day complication rate was 16.1%. 20 patients (12.4%) had minor complications, while major postoperative complications occurred in six patients (3.7%). Anastomotic leak was recorded in one patient (0.6%) and the 30-day re-admission rate was 0.6%. Mean number of harvested lymph nodes was 21.9. Patients requiring conversion experienced two minor complications, with a mean length of stay of 7 days. Robotic right colectomy with CME and IA is feasible and it is associated with good intraoperative and short-term postoperative clinical outcomes.

BACKGROUND: Complete mesocolic excision (CME) for right colectomy increase the technical complexity of a laparoscopic approach especially when an intracorporeal anastomosis (IA) is associated. The robotic platform, with its intrinsic technical advantages, could potentially overcome the limitations of conventional laparoscopy. This study aimed to describe the robotic bottom-up technique and to evaluate short-terms outcomes of robotic right colectomy (RRC) with CME and IA. METHODS: Data from patients who underwent RRC for cancer with bottom-up suprapubic approach from October 2016 to April 2020 were prospectively collected and retrospectively analyzed. Intraoperative outcomes and complications, conversion rate, 30-day postoperative outcomes, incisional hernia rate and pathological outcomes were the variables assessed. RESULTS: A total of 109 patients were submitted to bottom-up suprapubic approach for RRC with CME and IA during the study period. Mean operative time was 179 min, no intraoperative complications were observed, and the conversion rate was 3.6%. Mean postoperative stay was 4.6 days and the overall 30-day complication rate was 15.6%. Thirteen patients (12%) had minor complications, while major postoperative complications occurred in 4 patients (3.6%). Anastomotic leak was recorded in 1 patient (0.9%) and the 30-day re-admission rate was 0.9%. Mean number of harvested lymph nodes was 22.6. Incisional hernia rate at the specimen extraction site was 0.9%. CONCLUSIONS: Bottom-up approach for RRC with CME and IA carries a low rate of conversions, intraoperative and short-term postoperative complications.

Following the spread of the infection from the new SARS-CoV2 coronavirus in March 2020, several surgical societies have released their recommendations to manage the implications of the COVID-19 pandemic for the daily clinical practice. The recommendations on emergency surgery have fueled a debate among surgeons on an international level.We maintain that laparoscopic cholecystectomy remains the treatment of choice for acute cholecystitis, even in the COVID-19 era. Moreover, since laparoscopic cholecystectomy is not more likely to spread the COVID-19 infection than open cholecystectomy, it must be organized in such a way as to be carried out safely even in the present situation, to guarantee the patient with the best outcomes that minimally invasive surgery has shown to have.

BACKGROUND: One major issue in general surgery is how to provide novice surgeons with a structured training program (STP). The aim of our study was to assess the efficacy of a STP in robotic colorectal surgery for young surgeons without prior experience in both open and laparoscopic colorectal surgery, who were autonomous in basic minimally-invasive surgical procedures. Right colectomy with intracorporeal anastomosis has been chosen as a model. METHODS: Between May 2015 and December 2017 two junior attending surgeons were trained through a STP. Right colectomy was divided into three main learning modules (colonic mobilization, vascular control, intracorporeal anastomosis) and each one was carried out by the trainees for at least two times under direct supervision of the senior surgeon. After the initial robotic cases completely performed under formal proctoring, they were privileged to perform robotic right colectomy independently without a mentor (20 procedures). Operative time, conversion rate, intra- and postoperative complications, length of stay and pathological outcomes were the variables analyzed to assess the effectiveness of the STP. RESULTS: The mean operative time was 200 minutes and no conversion was required. Neither intraoperative nor major postoperative complications were recorded and the mean length of hospital stay was 6 days. Mean nodal yield was 21. CONCLUSIONS: A STP in robotic colorectal surgery is feasible and effective. Right colectomy represents a good model as first step of the program in order to develop multiple technical skills. Previous experience in open or laparoscopic colorectal surgery may not be necessary.

SUMMARY: Between September 2014 and December 2015, 32 patients with inguinal hernia were treated using a new 3D mesh in our department. This mesh is characterized by a multilamellar flower-shaped central core with a flat, large-pore polypropylene ovoid disk that has to be implanted preperitoneally. Compared with the traditional Lichtenstein procedure, we observed a shorter mean duration of surgery and a significantly lower mean visual analogue scale (VAS) postoperative pain score recorded immediately after the procedure in the 3D mesh group. The mean VAS score recoded after 4 and 8 postoperative days showed better results in the 3D mesh group than the control group. Moreover, there was reduced postoperative morbidity in the 3D mesh group than the control group, even if no patients experienced severe complications.
