PCORnet Bariatric Study Results (IMAGE) Patient-Centered Outcomes Research Institute Caption Based on assessments of tens of thousands of patients' experiences with weight-loss surgery, the PCORnet Bariatric Study provides patients and their doctors with a more complete picture about the comparative benefits and risks of the two most commonly used bariatric procedures Roux-en-Y gastric bypass and sleeve gastrectomy. The study compared the two procedures' average amount of weight lost and kept off, rates of Type 2 diabetes remission and return, and rates of short- and long-term health risks.
