The purpose of this research study is to evaluate whether combining laparoscopic adjustable gastric band (AKA: lap-band surgery, LAGB) and laparoscopic gastric plication (making tucks in the large curve of the stomach with stitches) to lap-band surgery alone will result in a greater loss of excess weight over time. We anticipate that the average percent of excess body weight loss for study subjects will exceed 29% at 12 months.
