Vertical banded gastroplasty

This operation also works by restriction and is sometimes referred to as ‘stomach stapling’.

At operation a circular window is created in the centre of the stomach with a small pouch above it secured by vertical rows of staples. Then a non–adjustable polypropolene band is inserted through the window at the base of the pouch to create the stoma which enables food to empty slowly from the pouch into the main stomach.

This operation is now considered by most surgeons to be obsolete, having been replaced by the gastric band. In 2003 it accounted for only 5% of all obesity surgery operations worldwide. Better outcomes have been seen with the other operations and there is a high rate of side effects with vertical banded gastroplasty, particularly tearing of the staple line. Also, because the band is fixed, the stomach pouch size and stoma are also non–adjustable and patients need to be very good at maintaining small portion sizes and chewing food thoroughly, otherwise regurgitation and vomiting are frequent.
