Weight loss after laparoscopic adjustable gastric banding: the role of race, BMI and age
Background/significance: Laparoscopic adjustable Gastric Banding (LAGB) has become one of the most common bariatric surgery procedures performed in the United States since its approval in 2001. According to the latest bariatric surgery studies, there is no disparity in the use of bariatric surgery b...

Methods:IRB approval was obtained to conduct a retrospective review of prospectively collected data for 852 patients who underwent a LAGB from February 2001 to February 2010.
