BACKGROUND: Obesity is a significant health problem in South Africa. Surgery is the most effective means of durable weight loss for the morbidly obese. Of the surgical options, laparoscopic adjustable gastric banding is the most controversial. We aimed to assess a single surgeon's experience with a specific band. METHODS: A retrospective observational study of a continuous cohort of laparoscopic adjustable gastric Cousin Bioring® band placements from a single private South African hospital was conducted. Three hundred and fifty bands were placed in 347 patients, 75% were female. Variables analysed were BMI obesity class, comorbidities, weight loss, diabetes resolution, adherence to aftercare, patient satisfaction, complications and death. RESULTS: Outcomes were assessed in 343 patients (4 patients lost to follow-up). The mean follow-up was 39 months (IQR 29-66 months). The mean preoperative BMI was 43.3 kg/m² (IQR 37.4-47.6 kg/m²). Most weight loss occurred in the first year, and 66% achieved > 40% excess weight loss. Resolution of type 2 diabetes and prediabetes occurred in 56.4% and 89.8% of patients respectively. Increasing age (p = 0.002), class 3 obesity (p < 0.001) and suboptimal aftercare (p < 0.001) were associated with failure. One patient developed band erosion and 40 developed band slippage, 34 of whom underwent secondary surgery (32 removals, 2 revisions). All complications were grade I-III. There was no high grade complication, and no death. CONCLUSIONS: Bioring® gastric banding achieved moderately good weight loss and resolution of type 2 diabetes with a low complication rate. BMI > 60 and suboptimal aftercare predicted poor outcome.
