One Anastomosis/Mini-Gastric Bypass (OAGB/MGB) as Revisional Surgery Following Primary Restrictive Bariatric Procedures: a Systematic Review and Meta-Analysis.

One anastomosis gastric bypass (OAGB/MGB) has gained popularity in the past decade. International databases were searched for articles published by September 10, 2020, on OAGB/MGB as a revisional procedure after restrictive procedures. Twenty-six studies examining a total of 1771 patients were included. The mean initial BMI was 45.70 kg/m2, which decreased to 31.52, 31.40, and 30.54 kg/m2 at 1, 3, and 5-year follow-ups, respectively. Remission of type-2 diabetes mellitus (T2DM) following OAGB/MGB at 1-, 3-, and 5-year follow-up was 65.16 ± 24.43, 65.37 ± 36.07, and 78.10 ± 14.19%, respectively. Remission/improvement rate from gastroesophageal reflux disease (GERD). Also, 7.4% of the patients developed de novo GERD following OAGB/MGB. Leakage was the most common major complication. OAGB/MGB appears to be feasible and effective as a revisional procedure after failed restrictive bariatric procedures.

Trends and progress of bariatric and metabolic surgery in India.

Bariatric and metabolic surgery are being performed in India for 2 decades. Aim of this paper is to evaluate the changing clinical trends over the last 5 years and to present the other aspects helmed by Obesity and Metabolic Surgery Society of India (OSSI) to aid the growth of research, education, data management and registry, quality control, insurance-related issues and policy change. OSSI conducts an annual survey to collect data pertaining to numbers of surgical procedures. With the approval of the executive committee, data collected from 2014 to 2018 were retrieved and analysed. 20,242 surgical procedures were performed in 2018 which is an 86.7% increase from 2014. Laparoscopic sleeve gastrectomy continued to remain the most popular procedure, it's percent share saw a steady decline from 68 to 48%. One anastomosis gastric bypass showed an unprecedented growth from 14 to 34%. Numbers of laparoscopic Roux en y gastric bypass remained constant at 15-16%. OSSI has also initiated a COE program along with training fellowships and focus on registry and inclusion in insurance coverage. National trends over the past 5 years in bariatric surgery have shown emergence of newer procedures like OAGB, although LSG continues to be the most popular procedure performed These trends give an insight on how the field is evolving and the implications for any distinctive requirements unique to this region These will lay out important directives for not only ensuring good treatment outcomes but also increasing awareness about the disease on the whole.
