PCORnet Bariatric Study

Providing real-world data to help make informed decisions about bariatric surgery

Welcome

Welcome to the PCORnet Bariatric Study (PBS) website. PBS is one of the first studies to use the PCORnet data, engagement, and governance infrastructure to conduct comparative effectiveness research.

Our Goal

The PCORnet Bariatric Study will compare the health benefits and safety associated with the three main methods of bariatric (also called weight loss) surgery. We seek to provide accurate estimates of the one-, three-, and five-year benefits and risks of having undergone either:

Roux-en-y gastric bypass (RYGB),
Adjustable gastric banding (AGB),
Sleeve gastrectomy (SG).

We are focusing on health outcomes that have been shown to be most important to adults and adolescents who are affected by severe obesity:

Weight loss,
Improvement in diabetes, and
Risk of adverse events.

Our ultimate goal is to provide patients and their health care providers the information they need to choose which surgery, if any, is best for them.
