ROUX-EN-Y GASTRIC BYPASS
The gastric bypass is a mixed surgery that allows a good restriction and a limited malabsorption. It has two parts. In the first part a small gastric reservoir made with a 30-40 ml capacity. In the second part a bypass is performed in order to diminish the fat absorption by the digestive tract.
History
For decades this procedure has been “the gold standard” in bariatric surgery. More recently it has been relegated to second place, although it is still the most accepted surgery for diabetic patients and those with pathological reflux.
