Abstract Introduction Bariatric surgery is the most effective treatment for obesity and its comorbidities. Nowadays, the robotic approach is the preferred method for superobesity and revisional surgery, mitigating the technical difficulty, improving the prognosis and diminishing the length of hospital stay. The objective of this study is to document our surgical experience with Robotic Bariatric Surgery and the One Anastomosis Gastric Bypass technique //MiniGastric Bypass // Bypass Gastrico de Una Sola Anastomosis (OAGB/MGB/BAGUA). The objectives of the statistical analysis were: 1.- To know the patient's demographic profile in both groups. 2.- To know the prevalence of present comorbidities. 3.- To compare the operative times of both groups: primary surgery versus revisional surgery. 4.- Apply a Linear Regression Analysis in order to know the trend for operative times according to BMI as a predictor variable. Twenty-three patients were included. Methods Seventeen patients underwent Robotic OAGB/MGB/BAGUA as a primary surgery (Group 1) and six patients underwent revisional surgery or conversion from Sleeve Gastrectomy to Robotic OAGB/MGB/BAGUA (Group 2). Results Table 1. Demographic Profile. (Upload File) Table 2. Comorbidities Profile in Both Groups. (Upload File) Table 3. Operative Times. (Upload File) COMPLICATIONS No complication 22 patients (95.7%) Complications: 1 (4.3%) patient; c.i. (95%): 0.11% to 21.94% Comparative statistical analysis was carried out, based on non-parametric tests: *Mann-Whitney U Test—Kolmogorov-Smirnov Test for the three surgical times: Docking, Console and Total Time in Group 1 and Group 2. In the three comparisons made, the statistical tests applied showed the levels of statistical significance: Docking and Console in Group 1 versus Docking Group 2, P = 0.420727 and P &amp;gt; 0.10; Total Time in Group 1 versus Console in Group 2, P = 0.325552 and P &amp;gt; 0.10 respectively. According to the operative times, there was no statistically significant difference between groups. The correlation between operative times and the body mass index (BMI) was studied with Linear Regression Analysis, considering BMI as a predictor variable and operative times as predicted variable. Both all three times, and groups were studied. We found a trend to decrease in surgical times, meanwhile, an increase in BMI was observed in this analysis. Conclusion We highlight in this summary the Total Time with a decrease index of 1 min/BMI Unit (weight/m2). The analysis of variance showed that the presence of comorbidities had no influence on surgical times.
