LAP-BAND adjustable gastric banding (LAGB)

Though gastric bypass surgery remains the most common procedure, Lap-Band® adjustable gastric banding is gaining in popularity because it has a low rate of complications and is less invasive than other procedures.

Description of the procedure:

Using an inflatable band, which has a similar function to a belt, the surgeon divides the stomach into two sections: a small upper pouch and a large lower one. The tightened band creates a narrow passage between the two areas that acts like an hourglass and filters food from the top pouch to the lower pouch. The result is a prolonged feeling of fullness. The procedure itself lasts about 30 minutes to an hour.

Unlike other procedures, LAGB allows for adjustments after the surgery has completed without the need for additional operations. The size of the stoma, or passageway that is created by the band, can be made larger or smaller depending on the weight loss goals of the patient. This adjustment can be made at any time after the procedure during a routine office visit, and it is a non-invasive, painless process.


  • The incision that is made for the insertion of the band is small (1 cm)
  • The stomach itself is neither cut nor stapled
  • Post-surgery adjustments to band “tightness” is non-invasive
  • Hospital stays usually do not exceed 48 hours
  • The procedure is fully reversible


  • It usually takes more time to see results with LAGB than it does with other procedures.
  • Patients who elect to have this procedure typically do not lose as much weight as those who elect to have other procedures.
  • The procedure is discouraged for patients with certain conditions (e.g., Crohn’s disease, gastric ulcers, large hiatal hernias).
