简要总结

In order to evaluate the difference in beta cell mass in patients with and without hyperinsulinemic hypoglycemia after Roux en Y gastric bypass (RYGB) investigators aim to compare quantitative PET imaging of the pancreas between these patient groups.

These highly relevant data will provide investigators with more information on the possible role of beta cell mass in the mechanisms of hyperinsulinemic hypoglycemia bariatric surgery.
