The Banded Bypass Surgery is a modification of the RYGB enhancing its restrictive component. The rationale for adding band to a gastric bypass surgery is that the pouch and the stoma sizes are important in the weight loss and weight maintenance.
In the banded GBP (Gastric By-Pass) the pouch and the stoma sizes are calibrated, standardized and reinforced. There is even evidence that the band in the GBP also results in less incidence of – outlet stenosis requiring dilatation, dumping syndrome and reactive hypoglycemia.
