Popis: The novel banded one-anastomosis gastric bypass (B-OAGB) procedure has not previously been reported in super-obese patients over the long term. In this pilot study, outcomes in patients with a mean baseline body mass index (BMI, kg/m2) of ≥ 50 who underwent B-OAGB were evaluated through 5-year follow-up. Total weight loss (TWL), excess weight loss (EWL), BMI evolution, and changes in type 2 diabetes biomarkers were analyzed prospectively in super-obese patients who underwent B-OAGB. Paired samples t tests were used to assess weight outcome change from baseline through 5-year follow-up and 95% CIs were calculated. The Bariatric Outcomes and Reporting System (BAROS) was used to assess surgical success at 3 time points. Between October 2013 and February 2014, a 12-patient pilot cohort (mean baseline BMI 57.5 ± 6.3) underwent B-OAGB. No perioperative complications were observed within 30 days. Five-year mean BMI was 31.2 ± 5.4, a BMI loss of 25.9 (TWL 45.3 ± 7.5%; EWL 72.2 ± 12.8%). Between 11 and 24 months following surgery, 3 patients required band removal; each had one complication (1 stasis esophagitis and recurrent vomiting; 1 hypoalbuminemia; 1 anemia). There was no mortality. Long-term B-OAGB BAROS subscale and composite scores were comparable to other major bariatric procedures. In a pilot study of super-obese patients who underwent B-OAGB, excellent durable BMI loss of 25.9 kg/m2 (EWL 72.2%) at 5 years was achieved with an acceptable level of reoperation. More B-OAGB long-term follow-up studies are necessary to provide definitive conclusions regarding this combination bariatric procedure.
