Abstract
OBJECTIVE: To evaluate the weight loss outcomes of banded Roux-en-Y gastric bypass (RYGB) during a 10-year follow-up. SETTING: Private health-providing service, Brazil. METHODS: A prospective study was conducted on 928 patients with obesity who underwent banded RYGB. Patients were divided into 2 groups according to their initial body mass index (BMI), morbid obesity (BMI 35-49.9 kg/m2) and super obesity (BMI ≥50 kg/m2). The percentages of excess weight loss (%EWL) and total weight loss (%TWL) at 18, 24, 36, 48, 60, 72, 84, 96, 108, and 120 months after surgery were assessed and compared, and the rates of surgical failure were also assessed. RESULTS: There were individuals who were lost to follow-up at each year, including 423 (45.6%) at 18 months, 431 (46.4%) at 24 months, 482 (51.9%) at 36 months, 568 (61.2%) at 48 months, 658 (70.9%) at 60 months, 725 (78.1%) at 72 months, 781 (84.2%) at 84 months, 819 (88.3%) at 96 months, 838 (90.3%) at 108 months, and 819 (88.3%) at 120 months. The maximal %EWL was achieved at 18 months (P<.001). After 10 years, there was no significant change in mean BMI (28.7 ± 4.1 versus 28.5 ± 3.6 kg/m2; P = .07) or %EWL (80.4 ± 19.1 versus 79.7 ± 23.4; P = .065), but the mean %TWL was significantly lower at 10 years (30.8 ± 8.5 versus 32.5 ± 8.1; P = .035) in the morbid obesity group, compared with the values observed over 5 years. In the super obesity group, the %EWL significantly decreased from 77.7 ± 16.5 kg/m2 at 24 months to 71.3 ± 18.1 kg/m2 at 72 months (P = .008); at 5 years, mean BMI (33.1 ± 5.8 kg/m2) did not differ from the one observed at 10 years (36.4 ± 5 kg/m2; P = .21), as well as the mean %TWL (40.1 ± 8.5 versus 34.8 ± 8.9; P = .334). CONCLUSION: Banded RYGB leads to significant and sustained weight loss in a 10-year follow-up. Despite a slight late weight regain evaluated by %TWL, RYGB leads to an optimal weight loss in the majority of the individuals.
