    Abstract:
    BACKGROUND: There are few studies of long-term outcomes for either laparoscopic adjustable gastric banding (LAGB) or laparoscopic Roux-en-Y gastric bypass (LRYGB). The objective of this study was to compare outcomes of patients randomly assigned to undergo LAGB or LRYGB at 10 years. METHODS: LAGB, using the pars flaccida technique, and standard LRYGB were performed. From January 2000 to November 2000, 51 patients (mean age 34.0 ± 8.9 years; range 20-49) were randomly allocated to undergo either LAGB (n = 27, 5 men and 22 women; mean age 33.3 years; mean weight 120 kg; mean body mass index [BMI] 43.4 kg/m(2)) or LRYGB (n = 24, 4 men and 20 women; mean age 34.7; mean weight 120 kg; mean BMI 43.8 kg/m(2)). Data on complications, reoperations, weight, BMI, percentage of excess weight loss, and co-morbidities were collected yearly. The data were analyzed using Student's t test and Fisher's exact test, with P<.05 considered significant. RESULTS: Five patients in the LAGB group and 3 patients in the LRYGB group were lost to follow-up. No patient died. Conversion to laparotomy was performed in 1 (4.2%) of 24 LRYGB patients. Reoperations were required in 9 (40.9%) of 22 LAGB patients and in 6 (28.6%) of the 21 LRYGB patients. At 10-year follow-up, the LRYGB patients had a greater percentage of mean excess weight loss than did the LAGB patients (69±29% versus 46±27%; P = .03). CONCLUSION: LRYGB was superior to LAGB in term of excess weight loss results (76.2% versus 46.2%) at 10 years. However, LRYGB exposes patients to higher early complication rates than LAGB (8.3% versus 0%) and potentially lethal long-term surgical complications (internal hernia and bowel obstruction rate: 4.7%).
