adjustable gastric band
A restrictive bariatric procedure involving placement of an inflatable silicone band around the upper stomach to create a small pouch.
Full Definition
An adjustable gastric band is a minimally invasive bariatric surgical procedure where an inflatable silicone band is placed around the upper portion of the stomach to create a small gastric pouch. The band can be tightened or loosened through a subcutaneous port, allowing for adjustment of restriction over time. This procedure is purely restrictive, meaning it limits food intake without altering digestion or absorption. While reversible, it has fallen out of favor due to higher complication rates and inferior long-term weight loss compared to other bariatric procedures.
