Background: Diabetes and other obesity-related diseases are a worldwide pandemic that transcends geographic borders as well as socioeconomic levels. Currently, it is well known that medical treatment alone is insufficient to ensure adequate and sustainable weight loss and co-morbidity resolution. It has been well proven that bariatric surgery can produce almost immediate resolution of diabetes and other co-morbidities as well as long-term weight loss. Objectives: Here, we present our experience with the one anastomosis gastric bypass (OAGB) in terms of weight loss and diabetes resolution with 1 year of follow-up. Setting: Large, metropolitan, tertiary, university hospital. Methods: A retrospective analysis of all patients who underwent OAGB between March 2015 and March 2016 was performed. Patient demographic characteristics, co-morbidities, operative and postoperative data, as well as first year outcomes were collected and analyzed. Results: There were 407 patients who underwent OAGB (254 females, average age 41.8 ± 12.05 yr, body mass index = 41.7 ± 5.77 kg/m2). Of patients, 102 (25.1%) had diabetes with average glycosylated hemoglobin of 8.64 ± 1.94 g%, 93 (22.8%) had hypertension, 123 (28.8%) had hyperlipidemia, and 35 patients (8.6%) had obstructive sleep apnea. The average length of hospital stay was 2.2 ±.84 days (range, 2–10 d). The average excess weight loss 1 year after surgery was 88.9 ± 27.3. After 1 year, follow-up data were available for more than 85% of the study's general population. Of 102 diabetic patients, only 8 (7.8%) were still considered diabetic and taking antidiabetic medication, with an average glycosylated hemoglobin of 5.4 ± 0.6. Conclusions: OAGB may be performed safely and with promising efficacy as both a primary and a revisional bariatric surgery, and it offers excellent resolution of diabetes.
