BACKGROUND: Open or laparoscopic Roux-en-Y gastric bypass (RYGBP) is the most common operation for treatment of morbid obesity in USA. The laparoscopic adjustable gastric band (LAGB) has been the most common bariatric operation performed worldwide. The LapBand was approved for use in USA in July 2001. Since then, several US surgeons have adopted one procedure preferentially over the other, and several have reported patient outcomes. We added the option of the LAGB to the RYGBP in our practice in July 2001. We hypothesized that both procedures will provide similar weight loss and co-morbidity reduction if followed for a sufficient length of time. To enhance weight loss, we adopted a patient behavioral program that is easy to remember, in an attempt to ensure a reduction in caloric intake and reduce hunger regardless of the operation performed.

METHODS: A case-controlled matched-pair cohort study was conducted. All patients who presented to the Surgical Weight Control Center of Las Vegas between Aug 2001 and Aug 2004 for LAGB were placed into one group, and a matched-pair RYGBP cohort group was created. Patients in the RYGBP cohort were matched for age, sex, date of surgery, and BMI. All patients were evaluated on an intention to treat basis. Data were collected prospectively and analyzed retrospectively. All patients were subjected to the same preoperative education regarding calorie reduction behaviors and diet change, and received the same postoperative counseling regarding long-term eating behavior and food choices.

RESULTS: During this period, 208 patients underwent LAGB and 600 underwent RYGBP. Of the 208 LAGB patients, 181 had suitable open or laparoscopic RYGBP matches. The two groups were similar in terms of age, sex, BMI, and co-morbidities. There were no deaths in either group. Resolution of co-morbidities statistically favored RYGBP as did the weight loss, over the study period.

CONCLUSION: When patients are matched with 3-year follow-up according to time of surgery, age, sex and BMI, LRYGBP provides superior weight and co-morbidity reduction and can be done without severe complications. However, the LAGB is an effective weight loss tool and not every patient wishes to have the LRYGBP.
