Bariatric surgery is one of the usual procedures in this unit. It is the only method that maintains long-term weight reduction, improving associated diseases, quality of life and self-esteem.

At Oncocir we develop two procedures

Vertical gastrectomy: it is a surgical procedure that consists of extracting approximately 80% of the volume of the stomach. A tube-like stomach is left which represents approximately 150-200cc capacity. Weight loss is achieved by the significant reduction that is made in the volume of the stomach, so it is considered a restrictive surgery.
Gastric bypass: the gastric bypass is a surgical procedure that achieves weight loss by two mechanisms, on the one hand a stomach of a very reduced capacity is built (20-50cc); and on the other hand, a crossing is made in the small intestine (bypass) that conditions that only approximately 60% is used for the digestion and absorption of food. This procedure has a restrictive and a malabsorptive component, which is why it is considered a mixed technique of bariatric surgery.
