In response to the growing rate of severe obesity and its consequences, the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) funded the development of the Longitudinal Assessment of Bariatric Surgery (LABS) consortium to address some of the many questions related to the safety and efficacy of bariatric surgery. Comprised of six clinical centers and one data coordinating center with a governing body, or Steering Committee, LABS is a multicenter, observational cohort study with strategically designed protocols for data collection and maintenance. Three phases of the LABS study (LABS-1, LABS-2, and LABS-3) assess the short- and longer-term risks and benefits of bariatric surgery and its associated outcomes and also examine several underlying mechanisms of effect in more detail. LABS-1 findings have described the short-term safety of bariatric surgery: 0.3 % mortality rate and 4.3 % risk of adverse composite outcome for primary bariatric surgical procedures. These results, along with the longer-term outcomes of LABS-2, addressing many of the outcome domains, will be published over the next several years and will contribute knowledge to the field to inform and hopefully benefit both patients and providers.
