How the LAP-BAND® Device Works

Less invasive. Faster recovery.

Gastric banding is a minimally invasive weight loss procedure. Unlike sleeve gastrectomy and gastric bypass, the LAP-BAND® Adjustable Gastric Banding System involves no use of metal surgical staples, no amputation of any part of the stomach, nor any cutting of the intestines.1,2

Data from the Bariatric Outcomes Longitudinal Database™ showed that sleeve gastrectomy had a 3x greater rate of total complications in the first year4* when compared to gastric banding. Additionally, data from the American College of Surgeons database within the first 30 days showed3 :


  • 3x greater chance of readmission to the hospital
  • 3x greater chance of reoperation
  • 3x the length of hospital stay following the procedure

In addition to a lower rate of complications in recent studies, gastric banding also offers a generally faster recovery time—it's typically performed as an outpatient procedure and you can usually get back to your normal activity in about a week's time.2

A breakthrough in lasting, healthy weight loss.

The LAP-BAND® System reduces your stomach's capacity, restricting the amount of food you are able to eat at one time.2

You also feel full faster and stay full longer. The revolutionary, yet simple technology is a less invasive bariatric option than either sleeve gastrectomy or gastric bypass3,4,5 to help you gradually lose weight and keep it off. So you can live a healthier life.

How it's done.

The LAP-BAND® System procedure is performed laparoscopically. This means a few very small incisions are made in the abdomen (about 1.5-2.5 cm each). The surgeon places the band around your stomach using long, thin instruments. A small camera allows the surgeon to see inside your body as he or she performs the procedure.2

Unlike sleeve gastrectomy or gastric bypass, which usually requires a stay of up to three days in the hospital, the LAP-BAND® System procedure is often done on an outpatient basis3 and the surgery itself typically takes less than an hour.2 When the procedure is performed in an inpatient setting, the hospital stay is generally less than one day.3
