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

PURPOSE: Sleeve Gastrectomy (SG) is the most performed bariatric surgery, but a considerable number of patients may require revisional procedures for suboptimal clinical response/recurrence of weight (SCR/RoW). Conversion options include One-Anastomosis Gastric Bypass (OAGB) and Single Anastomosis Duodeno-Ileal Bypass (SADI). The study aims to compare SADI vs. OAGB as revisional procedures in terms of early and mid-term complications, operative time, postoperative hospital stay and clinical outcomes. METHODS: All patients who underwent OAGB or SADI as revisional procedures following SG for SCR/RoW at three high-volume bariatric centers between January 2014 and April 2021 were included. Propensity score matching (PSM) analysis was performed. Demographic, operative, and postoperative outcomes of the two groups were compared. RESULTS: One hundred and sixty-eight patients were identified. After PSM, the two groups included 42 OAGB and 42 SADI patients. Early (≤ 30 days) postoperative complications rate did not differ significantly between OAGB and SADI groups (3 bleedings vs. 0, p = 0.241). Mid-term (within 2 years) complications rate was significantly higher in the OAGB group (21.4% vs. 2.4%, p = 0.007), mainly anastomotic complications and reflux disease (12% of OAGBs). Seven OAGB patients required conversion to another procedure (Roux-en-Y Gastric Bypass-RYGB) vs. none among the SADI patients (p = 0.006). CONCLUSIONS: SADI and OAGB are both effective as revisional procedures for SCR/RoW after SG. OAGB is associated with a significantly higher rate of mid-term complications and a not negligible rate of conversion (RYGB). Larger studies are necessary to draw definitive conclusions.

The increased operative time and costs represent the main limitations of robotic technology application to bariatric surgery. Robotic platforms may help the surgeon to overcome the technical difficulties in super-obese (SO, BMI ≥ 50 kg/m2) patients, in which multi-quadrant operations could be challenging. We aimed to evaluate the effect of robot-assisted (R) versus laparoscopic (L) approaches in Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy (SADI-S) and Roux-en-Y Gastric Bypass (RYGB) in SO and Super-Super Obese (SSO, BMI ≥ 60 kg/m2) patients in terms of outcomes and cost-effectiveness. Bariatric procedures performed from 2012 to 2023 were retrospectively reviewed. The inclusion criteria were BMI ≥ 50 kg/m2, primary SADI-S or RYGB. Operative time (OT), early complications, post-operative stay (POS), overall costs and follow-up data were analyzed. A subgroup analysis for surgical procedures and SSO patients was also performed. Among 4596 patients, 174 RYGB and 91 SADI-S in BMI ≥ 50 kg/m2 patients were selected. After Propensity Score Matching analysis, two groups of patients were identified (laparoscopic and robot-assisted), each one composed of 18 RYGB and 26 SADI-S. Intraoperative and post-operative complication rates and POS were comparable. Mean OT was longer in robotic procedures compared with laparoscopy (199.1 ± 65.7 and 109.5 ± 39.1 min, respectively, p < 0.001). The difference in OT was eliminated after only SSO patients were included in the analysis (172.7 ± 24.1 vs 152.6 ± 26.2 min for R-SADI-S and L-SADI-S, respectively, p = 0.107). Robotic surgeries were associated with higher costs (8134.6 ± 1886.7 and 2386.7 ± 388.2 in R-RYGB and L-RYGB, respectively; 7996.6 ± 873.1 and 3954.6 ± 631.1 in R-SADI-S and L-SADI-S). Despite increased costs, robotic approach may represent an added value in more complex cases such as SSO patients.

Robotic assisted surgery is a rapidly developing field in bariatric surgery. Its wide diffusion has led to the development and standardisation of robotic assisted approaches for various bariatric operations. However, further application has been limited thus far due to issues of cost-effectiveness and accessibility. The introduction of new robotic platforms may help overcome those obstacles. In this study, we present the first fifteen cases of Roux-en-Y Gastric Bypass (RYGB) operations performed with the new Hugo™ RAS system (Medtronic, Minneapolis, MN, USA). From January to March 2023, consecutive patients scheduled for minimal invasive Roux-en-Y-Bypass were randomly selected and underwent the procedure robotic-assisted with the new platform. No exclusion criteria were applied. Seven female and eight male patients with a median BMI of 42 (range: 36-50) and obesity-related comorbidities in eight cases underwent RYGB. The median docking time was 7 min (range: 6-8.5) and the median console time was 100 min (range: 70-150). Procedures were performed without intraoperative complications and no conversion to laparoscopy or open surgery was noted. Operative times were indicative of a steep learning curve. No early post-operative complications were observed. Based on our initial experience, RYGB with the Hugo™ RAS system is promising and may be integrated in established robotic programmes without requiring a long adaptation period.

Introduction: Robotic assisted surgery is a rapidly developing field of minimally invasive bariatric surgery in the last 20â years. Its wide diffusion has led to the development and standardization of robotic assisted approaches for bariatric operations. In this study, we present the first four Roux-en-Y Gastric Bypass (RYGB) operations performed with the new Hugo™ RAS system (Medtronic, Minneapolis, MN, USA). Methods: In January and February 2023, 4 consecutive patients scheduled for minimal invasive Roux-en-Y-Bypass were selected and underwent the procedure robotic-assisted with the new platform. No exclusion criteria were applied. Results: Four patients, two females and two males, underwent RYGB with a median BMI of 40 Kg/m2 (range: 36-46) and diabetes mellitus in two cases. The median docking time was 8â min (range: 7-8.5) and the median console time was 127.5â min (range: 95-150). A description of the operating theatre, robotic arms and docking setup is provided. Procedures were performed without intraoperative complications and no conversion to laparoscopy or open surgery was noted. No additional ports were needed to be placed. System's function and docking were uneventful. No early post-operative complications were observed. Conclusions: Based on our initial experience, RYGB with the Hugo™ RAS system is feasible. This study provides the configurations necessary to perform RYGB with the Hugo™ RAS system as well as general information and insights from our preliminary experience.
RESUMO
INTRODUCTION: Single Anastomosis Duodenal-Ileal Bypass with Sleeve Gastrectomy (SADI-S), like other hypoabsorptive procedures, could be burdened by long-term nutritional deficiencies such as malnutrition, anemia, hypocalcemia, and hyperparathyroidism. OBJECTIVES: We aimed to report our experience in terms of mid-term (2 years) bariatric, nutritional, and metabolic results in patients who underwent SADI-S both as a primary or revisional procedure. METHODS: One hundred twenty-one patients were scheduled for SADI-S as a primary or revisional procedure from July 2016 to February 2020 and completed at least 2 years of follow-up. Demographic features, bariatric, nutritional, and metabolic results were analyzed during a stepped follow-up at 3 months, 6 months, 1 year and 2 years. RESULTS: Sixty-six patients (47 female and 19 male) were included. The median preoperative BMI was 53 (48-58) kg/m2. Comorbidities were reported in 48 (72.7%) patients. At 2 years, patients had a median BMI of 27 (27-31) kg/m2 (p < 0.001) with a median %EWL of 85.3% (72.1-96.1), a TWL of 75 (49-100) kg, and a %TWL of 50.9% (40.7-56.9). The complete remission rate was 87.5% for type 2 diabetes mellitus, 83.3% for obstructive sleep apnea syndrome and 64.5% for hypertension. The main nutritional deficiencies post SADI-S were vitamin D (31.82%) and folic acid deficiencies (9.09%). CONCLUSION: SADI-S could be considered as an efficient and safe procedure with regard to nutritional status, at least in mid-term (2 years) results. It represents a promising bariatric procedure because of the excellent metabolic and bariatric outcomes with acceptable nutritional deficiency rates. Nevertheless, larger studies with longer follow-ups are necessary to draw definitive conclusions.

PURPOSE: Biliopancreatic diversion with duodenal switch and single anastomosis duodenal-ileal bypass with sleeve gastrectomy (SADI-S) are technically demanding hypo-absorptive bariatric procedures generally indicated in super-obese patients (BMI ≥ 50 kg/m2). Data from the literature prove the procedure to be safe and effective, with promising bariatric and metabolic effects. Anyway, international societies support the creation of multicentric national and international registries to obtain more homogeneous data over the long period. We aimed to report our experience with this procedure. METHODS: Among 2313 patients who underwent bariatric procedures at our institution, between July 2016 and August 2021, 121 (5.2%) consenting patients were scheduled for SADI-S as primary (SADIS) or revisional procedure after sleeve gastrectomy (SADI) (respectively 87 and 34 patients). Early and late post-operative complications, operative time, post-operative stay, and follow-up data were analyzed. RESULTS: Overall, the median preoperative BMI was 52.3 (48.75-57.05) kg/m2 with a median age of 44 (39-51) years, the median operative time was 120 (100-155) min. Complications at 30th-day post-op were registered in 4 (3.3%) patients and late complications in 4 (3.3%) patients. At a median follow-up of 31 (14-39) months, the median percentage excess weight loss was 79.8 (55.15-91.45)%, and the median total weight loss was 57.0650 (43.3925-71.3475)%. CONCLUSION: Our data, coherently with the literature, confirm that SADI-S is a safe, effective procedure with acceptable complications rate. Larger studies with longer follow-ups are necessary to draw definitive conclusions.
