Our physicians at Oregon Weight Loss Surgery, LLC actively participate in many research studies and clinical trials. Our patients benefit from these research activities by actively working with us to contribute to the scientific community at-large, helping to answer questions about bariatric surgery and weight loss.
Sometimes there is financial compensation for time and travel for patients who elect to participate in a research study. A separate application and screening process may be required for entry into each study. Specific study information is available below. Additionally, information on current research studies will be presented at new patient information sessions. To address any further questions concerning research at OWLS, please contact (503) 863-5255 and ask to speak with one of our research coordinators.

LABS-2 – Longitudinal Assessment of Bariatric Surgery
The Longitudinal Assessment of Bariatric Surgery (LABS) is a National Institutes of Health (NIH)-funded consortium of six clinical centers, including Oregon Weight Loss Surgery / Legacy Good Samaritan Hospital, and a data coordinating center working in cooperation with NIH scientific staff to plan, develop, and conduct coordinated clinical, epidemiological, and behavioral research in the field of bariatric surgery.
The primary objective of LABS-2 is to use standardized techniques and measures to assess the long-term safety and efficacy of bariatric surgery by comparing post-surgical outcomes to pre-operative status and examining risks and benefits of surgery. LABS-2 also strives to 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.
LABS-3 – Longitudinal Assessment of Bariatric Surgery diabetes study
LABS-3, which includes selected subsets of patients from the LABS-2 cohort, has been devised to conduct detailed studies of mechanisms involved in weight loss and weight gain, energy expenditure, glucose control, and other aspects of the pathophysiology of obesity and obesity-related complications.
The goal the LABS-3 study is to examine the physiological mechanisms that contribute to improvements of glucose homeostasis in type-2 diabetes mellitus (DM) following gastric bypass Roux-en-Y surgery (GBP).
The PDF document on this page contains a list of all publications that reference the LABS studies.
At Oregon Weight Loss Surgery we are committed to studying the disease of obesity. At this time we are evaluating several possible projects. Please check back periodically for future developments.
