We are proud to be the flagship centre for the By-Band-Sleeve research study, which is co-ordinated by the Clinical Trials and Evaluation Unit, University of Bristol. The By-Band-Sleeve research study is the world’s largest randomised control trial comparing the three main surgeries used globally to treat severe and complex obesity: gastric bypass, gastric band and sleeve gastrectomy. The study will be primarily comparing weight, quality of life and cost effectiveness of surgery. We have recruited over 200 patients at Musgrove Park Hospital and over 1000 nationally across 12 participating centres. Patients are followed up by the research team for eight years from the date they join the study. For more information call 01823 343514.
