Laparoscopic Adjustable Gastric Band

An Adjustable Gastric Band (AGB), also known as a lap-band, is a silicone device that is placed around the upper part of the stomach to treat obesity. The band creates a small pouch, which limits food intake and helps individuals feel full faster, ultimately leading to weight loss.

This minimally invasive procedure involves placing an adjustable band around the upper part of the stomach to create a small pouch, which limits food intake and promotes a feeling of fullness.

Adjustable Gastric Band Design Features

Adjustable gastric bands typically hold between 4 and 12 cc of saline solution, depending on their design and the specific manufacturer. The amount of saline in the band can be adjusted to control the level of restriction and tailor it to the individual’s needs and weight loss progress.

Some bands, like the LAP-BAND® system, have a maximum capacity of 4mL (4 cc) of saline. Others may hold more, up to 12 cc. It’s important to note that the amount of saline required for optimal restriction varies for each person and is determined by the healthcare provider through a series of adjustments.

Band material: Silicone is used due to its biocompatibility and durability. It is also flexible, allowing for adjustments.

Inflation mechanism: The band contains an inner balloon that can be filled with saline solution to adjust the tightness of the band around the stomach.

Port and tubing: A port is placed under the skin, connected to the band via tubing. This port allows a healthcare provider to inject or remove saline to adjust the band without further surgery.

Adjustable diameter: The diameter of the band can be adjusted to accommodate individual patient needs and weight loss goals.

Locking mechanism: Some bands have a locking mechanism to prevent accidental adjustments or slippage.

The design of AGBs aims to be minimally invasive and reversible, offering a less drastic option compared to other bariatric surgeries. 1 The adjustability feature allows for personalization of the weight loss journey and adaptation to the patient’s progress.

Overall, Adjustable Gastric Banding can be an effective tool for weight loss when combined with a comprehensive lifestyle change program. However, it’s important to consult with a healthcare professional to discuss the risks and benefits and determine if it’s the right option for you.
