Mean excess body weight loss in the LRYGB and LAGB after 12 months averaged 69.62% and 32.58%, respectively. Mean operating room time was 112.80 minutes for LRYGB surgery and 72.10 minutes for LAGB surgery. Mean length of stay was 22 hours 45 minute for LRYGB and 7 hours 18 minutes for LAGB

Individuals considering weight-loss surgery can have adjustable gastric banding or gastric bypass surgery done safely in under two hours on an outpatient basis at an ambulatory surgery facility, according to a study in the latest issue of the peer-reviewed Journal of the Society of Laparoendoscopic Surgeons (JSLS).

The obesity epidemic in the U.S. has led to a rapid rise in the number of bariatric procedures performed each year (205,000 in 2007 compared to 16,200 in 1992). Until recently, laparoscopic adjustable gastric banding (LAGB) and laparoscopic Roux-en-Y gastric bypass (LRYGB) were performed in a hospital setting. Little was known of the safety and feasibility of performing the surgical procedures at ambulatory surgery centers (ASC).

From 2002 to 2008 Kent Sasse, M.D., M.P.H., FACS and colleagues at Western Bariatric Institute initiated a study to determine the safety and effectiveness of laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic adjustable gastric banding (LAGB) on carefully selected patients at ASCs. They conducted 248 bariatric procedures, specifically 210 LAGB and 38 LRYGB procedures.

Prior to surgery, the LRYGB patients had a mean BMI of 44.7 (seven patients had a BMI over 60), and in the LAGB patient group the mean BMI was 43.79. "Mean excess body weight loss in the LRYGB and LAGB after 12 months averaged 69.62% and 32.58%, respectively. Mean operating room time was 112.80 minutes for LRYGB surgery and 72.10 minutes for LAGB surgery. Mean length of stay was 22 hours 45 minute for LRYGB and 7 hours 18 minutes for LAGB," the authors write.

"This marks a turning point in the battle against obesity, by shifting life-changing weight-loss surgery to the outpatient arena with minimally invasive surgery. This study further validates the hypothesis that an overweight person can safely undergo weight-loss surgery in about two hours, at an outpatient surgical facility, return home later the same day, take very little time off, and lose a large amount of weight," says lead author, Dr. Sasse.

Dr. Sasse is the author of the book Outpatient Weight-Loss Surgery: Safe and Effective Weight Loss with Modern Bariatric Surgery (360 Publishing; April 2009), a comprehensive, unbiased, and informative guide to today's outpatient bariatric surgery. Dr. Sasse is a leading physician, and an acclaimed authority on surgical weight-loss procedures. He is founder and medical director of iMetabolic® also know as the International Metabolic Instituteā„¢ and Western Bariatric Institute, a nationally recognized ASMBS Center of Excellence.
