A gold-standard bariatric research biobank

The Geisinger Obesity Institute is uniquely positioned to explore the countless benefits of surgical weight loss. Beginning in 2004, a prospective, robust bariatric registry has been supported by data from the electronic health record, patient reported results, and a vast biobank of patient samples including blood, serum, liver, adipose, stool, stomach, and jejunum. The registry is one of the largest and most expansive in the world, including data and samples from over 6,000 research consented patients with excellent long-term follow-up (80% at 4-years after surgery). This bariatric research cohort is recognized globally as a gold standard for bariatric research and has been used within >50 peer reviewed research publications.
