Laparoscopic Adjustable Gastric Band (LAGB)

A laparoscopic adjustable gastric band being placed around the stomach.

The Laparoscopic Adjustable Gastric Band, commonly referred to as a lap-band, A band, or simply LAGB, is a medical device used in the treatment of obesity. It is designed to reduce food intake by constricting the upper part of the stomach.

Overview

LAGB is a form of bariatric surgery, specifically indicated for weight management in obese patients. The device itself is an inflatable silicone band that is placed around the top portion of the stomach via laparoscopic surgery, which is minimally invasive and allows for a quicker recovery time compared to traditional open surgery.

Indications

This surgical procedure is generally recommended for patients with a Body Mass Index (BMI) of 40 or higher. It may also be considered for patients with a BMI between 35 and 40 who have obesity-related comorbid conditions, such as:

• Sleep apnea
• Diabetes
• Osteoarthritis
• GERD
• High blood pressure
• Metabolic syndrome

Procedure

During the procedure, surgeons typically use a laparoscope to place the gastric band without making large incisions in the abdomen. Once in place, the band is secured around the upper portion of the stomach, creating a small pouch above the band with the larger part of the stomach below the band.

Adjustability and Follow-up

One of the unique features of the LAGB is its adjustability. The band is connected to an access port that is left under the skin. Saline can be injected or removed through this port, allowing the band to be tightened or loosened as needed to meet the patient's weight loss needs or to manage side effects.

Outcomes and Benefits

LAGB has been shown to result in significant weight loss when coupled with lifestyle changes. The benefits extend beyond weight reduction, as many of the comorbid conditions associated with obesity, such as those listed above, often improve or resolve following successful weight loss with the band.

Risks and Considerations

As with any surgical procedure, LAGB carries risks, including complications from surgery, the band slipping or eroding, and the need for reoperation. Long-term commitment to dietary changes and regular follow-up with the surgical team are essential for the success of the procedure.
