Gastric bypass surgery has been tried and tested for over 40 years. It’s a procedure where the stomach is partitioned to a smaller size and small bowel is re-routed to this new gastric pouch. In the banded gastric bypass a fixed silastic ring is placed around the gastric pouch.
A few years ago, Lap band surgery was the most common bariatric operation performed in Australia. It has gradually declined in use due to high long-term revision surgery and complication rates.
