Background: The disease of obesity mostly common in the developed countries is also predominantly seen in the developing countries in recent times. This is therefore a cause to worry. Aim: To review literature comparing Roux-en-Y gastric bypass (RYGB) and mini-gastric bypass (MGB) to ascertain the more effective and safe bariatric and metabolic operation. Materials and methods: Detailed literature review online was perfected via Springer Link, International Bariatric Club, and the World Health Organization. Of immense use was a database of 1,000 bariatric surgeries collated from multiple hospitals in the developing countries. Conclusion: Both bariatric procedures are effective in the treatment of morbid obesity by restriction and malabsorption. They resolve obesity-related metabolic complications and hence increase quality of life for morbidly obese patients. However, in their comparison, MGB take lesser time to perform than RYGB. Also, MGB has shown to be simpler and safer surgery than RYGB. Thus, in the developing country, with its high population and increasing prevalence of morbidly obese individuals, MGB procedure can be used to treat more patients and also reduce the time and energy taken to manage the patient because of its technical ease, efficacy, revisibility, and reversibility. Overall, a zero mortality in MGB makes it the gold standard in bariatric surgery.
