Banded Roux-en-Y Gastric Bypass is a surgical procedure that can be performed by laparoscopy, which consists of a classic gastric bypass with the addition of a ring to potentiate its restrictive aspect. The procedure reduces food intake and reduces the absorption of nutrients from the food. Absorption of nutrients is limited because part of the intestines is bypassed and not used.

 

The procedure determines the creation of a small gastric pouch (20-30 ml) and the bypass is performed creating an alimentary limb of 150 cm and a biliary limb of 100 cm. The junction between the stomach pouch and small bowel is controlled by a ring in different material (silastic, biologic, mesh). Besides its restrictive role, the ring contributes to the reduction of undesirable side-effects like dumping syndrome, and foul flatulence. The banded bypass causes satiety and reduces caloric intake through retarding gastric emptying and inducing the satiation sensation even with low food intake. The ring controls the diameter and area of the gastoenterostomy.

 

It is of paramount importance after this type of surgery the compliance to vitamin supplementation and to follow-up in order to avoid nutritional deficiencies.
