Which band?

Post  Admin on Tue Aug 03, 2010 1:42 am

A laparoscopic adjustable gastric band, commonly referred to as a lap band, is an inflatable silicone device that is placed around the top portion of the stomach, via laparoscopic surgery, in order to treat obesity. Adjustable gastric band surgery is an example of bariatric surgery designed for obese patients with a body mass index (BMI) of 40 or greater—or between 35–40 in cases of patients with certain comorbidities that are known to improve with weight loss, such as sleep apnea, diabetes, osteoarthritis, GERD, Hypertension (high blood pressure), or metabolic syndrome, among others.

Types of adjustable bands

In the US market, two types of adjustable gastric bands have been approved by the FDA: Realize Band and Lap-Band. The Lap-Band System (Allergan Inc., Irvine, CA) obtained FDA approval in 2001. The device comes in five different sizes and has undergone modification over the years. The latest models, the Lap-Band AP-L and Lap-Band AP-S, feature a standardized injection port sutured into the skin and fill volumes of 14 mL and 10 mL respectively.

The Realize Adjustable Gastric Band (Ethicon Endo-Surgery, Inc., Cincinnati, OH) obtained FDA approval in 2007. Realize Band-C has a 14% greater adjustment range than the Realize Band. But both the Realize Band and Realize Band-C are one-size-fits-all. The device differentiates itself from the Lap-Band AP series through its sutureless injection port installation and larger range of isostatic adjustments. The maximum fill volume for the Realize Band is 9mL, while the newer Realize Band-C has a maximum fill capacity of 11mL. Both fill volumes fall within a low pressure range to prevent discomfort or strain to the band.

Two other adjustable gastric bands are in use outside of the United States: Heliogast and Midband. Neither band has been approved by the FDA but is approved under EU law. The Midband (Médical Innovation Développement, Limonest, France) was the first to market in 2000. In order to preserve the gastric wall in the event of rubbing, the device contains no sharp edges or irregularities. It is also opaque to x-rays, making it easy to locate and adjust.

The Heliogast band (Helioscopie, Rhône-Alpes, France) entered the market in 2003. The device features a streamlined band to ease insertion during the operation.

It is best to discuss which band your surgeon uses and make a decision from there.
