The primary objective of LABS-2 is to use standardized techniques and measures to assess the longer-term safety and efficacy of bariatric surgery by:
LABS-2 will determine the associations between clinical/demographic patient characteristics, components of the surgical procedure, and peri-operative and post-operative care with post-operative risks and changes in patient status.
Funds are not available to pay for the surgery for patients, only to address research questions.
The primary goal of LABS-2 is to evaluate the efficacy and safety of bariatric surgery over a longer term than LABS-1, i.e., more than 30 days. Using a sample of the LABS-1 cohort, approximately 2,400 patients, will be recruited over 3 years. LABS-2 will include clinical assessments and detailed interviews and questionnaires pre-operatively and at several post-operative time points (30 days, 6 months, 12 months following surgery, and annually thereafter) to assess risks of surgery, and changes in clinical, metabolic, and psychosocial characteristics in patients, and health care utilization following bariatric surgery. Detailed data about the surgical procedure and peri- and post-operative care will also be collected to determine if components of the surgical procedure, and peri-operative and post-operative care as well as clinical/demographic patient characteristics are associated with post-operative risks and changes in patient status. Patients enrolled in LABS-2 will provide blood specimens pre-operatively and post-operatively to address LABS-2 hypotheses and additional samples will be stored at the NIDDK tissue repository for serologic, pathologic and genomic testing of other hypotheses.
