Definition By – Pass Gastric en Y. Laparoscopic Roux-en-Y gastric bypass (RYGB)
Gastric By-pass consists in creating a small gastric pocket in which the food arrives. This pocket has a very reduced capacity.
It is connected directly to the jejunum (handle in there): the food passes in the intestine by shorting-circuit most of the stomach, the duodenum and the jejunum.
The By-pass allows the reduction of the caloric intake and also of the absorption of the nutritive substances. It is about a surgery for mixed purpose: restriction and malabsorption.
The weight loss is explained by 4 mechanisms
Small of the gastric pocket (30-50 DC).
Malabsorption whose importance varies according to the length of the excluded jejunum.
Reduction of the rate of the hormone ghréline.
Dumping syndrome associated with ingestion with sweetened food (Malayan, diarrhoeas, sudation).
At the obese patient with rather anarchistic food with sweetened nibbling and concept of assumption of great quantities of sodas (“dumping syndrome “).
