LAGB is a type of bariatric surgery that uses an adjustable band to restrict the size of the stomach. The procedure is performed laparoscopically, implying that it involves small incisions in the abdomen rather than one large cut. The band creates a small stomach pouch above it, with a narrow opening to the larger portion of the stomach below. This small pouch ensures that even with a small quantity of food, there is a feeling of fullness.

Key features of LAGB include:

• Minimally invasive procedure
• Adjustable and reversible
• No stapling or cutting of the stomach
• Typically requires a short hospital stay

Why is it done?
LAGB is recommended for individuals with severe obesity who have not achieved long-term success with non-surgical weight loss methods. Specific criteria for LAGB include:

• Body Mass Index (BMI) greater than 40, or
• BMI of 35 or higher with obesity-related health conditions such as type 2 diabetes, sleep apnoea, or hypertension

The procedure aims to help patients achieve significant weight loss, improve obesity-related health conditions, and enhance overall quality of life.

What happens during the procedure?
The LAGB procedure typically involves the following steps:

• General anaesthesia is administered to the patient.
• The surgeon makes 1 to 5 small incisions in the abdomen to insert a camera and surgical instruments.
• Using laparoscopic techniques, the surgeon places the adjustable silicone band around the upper part of the stomach.
• The band is connected to a small port placed under the skin of the abdomen, usually near the rib cage.
• The incisions are closed, completing the procedure.

The entire surgery usually takes between 30 to 60 minutes when performed by an experienced surgeon. Post-surgery, the band can be adjusted by adding or removing saline solution through the port, allowing for customization of the stomach opening size to meet the patient's weight loss needs and comfort level.
