Methods
Preoperatively, all patients provided written informed consent for their operation and to have de-identified data analyzed for presentation and/or publication. The institutional review board approved this study. Data from a prospectively maintained database of all bariatric metabolic operations performed at [Mohak Bariatrics and Robotics Center, Indore] in 2012 were identified. Patients who had either RYGB or OAGBP were identified. Patients were usually offered either of the procedures. The
Results
Seven hundred twenty-four patients were identified who had bariatric procedures at our center in 2012. One hundred twenty-two had RYGB and 90 had OAGB. The average age was 44 and 46.4 years in the OAGB and RYGB groups, respectively. The OAGB group (66.7%) included more male patients compared with the RYGB group (53.2%) (Table 1). Mean body mass index and the incidence of T2D and OSAS were statistically significantly more in the OAGB group (Table 1). The average surgical time for the OAGB was 55
Technical ease of performing the OAGB
Among all bariatric procedures, RYGB has stood the test of time and is considered the gold standard [4], [5], [12]. However, it is a technically demanding procedure, with a long learning curve and increased perioperative morbidity [6], [7]. OAGB is fast emerging as an alternative bypass procedure that is not only technically easy but is reported to have similar if not better results regarding weight loss and resolution of metabolic syndrome (MS) [8], [9], [10], [11], [13]. In this study, the
Conclusion
At intermediate- to midterm follow-up of 5 years in this study, both RYGB with the 80-cm BP limb and 120-cm Roux limb and OAGB with a >200-cm BP limb appear to be effective procedures resulting in good weight loss outcomes and resolution of co-morbidities, including T2D and HTN. However, OAGB with a biliopancreatic limb of >200 cm yields better weight loss and weight loss maintenance in addition to resolution of co-morbid conditions in the treatment of severe obesity, albeit at the expense of a

2022, Surgery for Obesity and Related DiseasesCitation Excerpt :Previous studies have shown that failed primary LAGB is best managed by converting to another bariatric technique such as OAGB or RYGB [14,21]. Furthermore, for primary procedures, previous studies have shown significantly greater weight loss for primary OAGB versus primary RYGB after a 5-year follow-up [8–10,22,23]. However, results for conversion procedures and particularly comparing the 2 techniques after a failed LAGB remain scarce.
