Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

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: 1. comparing post-surgical outcomes to pre-operative status 2. examining risks and benefits of surgery. 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.
