Summary

Dr. Freeman is chief of the Division of Gastroenterology, Hepatology, and Nutrition, medical director of the program for total pancreatectomy and islet autotransplantation and director of the advanced pancreaticobiliary endoscopy fellowship at the University of Minnesota. He has trained numerous advanced endoscopists, many of whom have gone on to leadership positions, and has led and participated in numerous courses in Advanced Endoscopy for the ASGE. He was the lead author on three educational DVD's for the ASGE including techniques for biliary access during ERCP, endoscopic therapy of pancreatic disease, and on interventions for necrotizing pancreatitis. He received the Master of Endoscopy Award by the American Society for Gastrointestinal Endoscopy in 2012, served as President of the American Pancreatic Association in 2013, and in 2019 was honored as a Master of the American College of Gastroenterology.

Dr Freeman's main clinical and research interests involve pancreatic and biliary disorders, with a focus on interventional endoscopy. Dr. Freeman has published over 30 textbook chapters, and 250 peer reviewed articles, including several index papers for which he was the principal author: a multicenter study on ERCP complications in the New England Journal of Medicine, a multivariable model for prediction of post ERCP pancreatitis in Gastrointestinal Endoscopy, guidelines for the management of acute pancreatitis in the American Journal of Gastroenterology, and a consensus paper and a systematic review on interventions for necrotizing pancreatitis in the journals Pancreas, and recently in Gastroenterology . Other research areas include drainage of malignant hilar obstruction and treatment of sphincter of Oddi dysfunction, for which he was a contributor to a recently completed multicenter NIH funded randomized trial. Major directions of his clinical interests and research at present include management of severe acute pancreatitis, recurrent acute pancreatitis, pancreaticobiliary cancers, and diagnosis and management of chronic pancreatitis.
