In recent years, a surgical technique known as single anastomotic gastric bypass or mini gastric bypass has been developed. This procedure, originally described by Rutledge in 1997, is a simplified form of Roux-en-Y bypass by performing a single anastomosis with a significant reduction in technical complexity, shorter operative time and a potential reduction in morbidity and mortality.
Several studies have demonstrated the benefits conferred by this procedure, including excess weight loss and treatment of comorbidities (type 2 diabetes, high cholesterol, sleep agne syndrome, high blood pressure, etc.) equivalent to those observed after Roux-en-Y gastric bypass. Weight loss, both by reducing food intake and by reducing the absorption of the food eaten. Improves insulin sensitivity by early stimulation of intestinal hormones by food
