Comparative Outcomes of sleeve gastrectomy and adjustable gastric banding

Background: Laparoscopic sleeve gastrectomy has rapidly emerged as the most commonly performed bariatric surgical procedure in Australia. This has represented a paradigm shift away from laparoscopic adjustable gastric banding (LAGB), that represented more than 90% of procedures for nearly 15 years. LAGB has the advantages of safety, simplicity and adjustability. It does require intense follow up and behavioural change. Sleeve gastrectomy is a higher risk procedure, with reported improved efficacy, better eating quality and reduced follow up requirement. There are few objective data comparing outcomes of the two procedures, with most reports lacking a control group or demonstrating significant methodological bias. GOAL: To better understand the differences between the procedures in terms of objective outcomes, patient satisfaction and economic feasibility. A matched cohort study will be undertaken, with data collected on peri-operative outcomes, complications, costs, weight loss as gastro-intestinal symptoms and overall satisfaction. Costs of the two procedures will be calculated. Aims: To determine the differences between LAGB and sleeve gastrectomy in terms of: 1) Weight loss 2) Peri-operative complications and outcomes 3) Gastro-intestinal symptoms 4) Co-morbidity change 5) Patient satisfaction and quality of life 6) Costs
