GI Update

The GI Update is an annual, full-day CME event hosted by the Gastroenterology/Hepatology Division at Indiana University School of Medicine. The course features updates on recent literature in upper and lower GI tract, liver and pancreatobiliary disease as well as presentations on specific topics of interest to primary care providers. Typically held on the first Friday in May, this course is regularly attended by more than 200 primary care providers, gastroenterologists and gastroenterology nurses.

Clinical Facilities

The endoscopy units at IU Health University Hospital and the Spring Mill location were recently renamed for Drs. Glen Lehman and Douglas Rex, respectively. This Division of Gastroenterology and Hepatology established the David W. Crabb Endowed Chair in Gastroenterology and Hepatology to honor Dr. Crabb’s years of dedication and contributions to many missions of the medical school. An ERCP suite at the University Hospital recently underwent a $10 million renovation and is expected to become the best-equipped unit in the United States.

History of the Division

 The Division of Gastroenterology and Hepatology at IU School of Medicine was founded by Dr. Philip Christiansen in 1958 and flourished under the leadership of Drs. Lawrence Lumeng (Division Director from 1984 to 2007) and Glen Lehman (Clinical Director from 1985 to 2005) to national prominence. Under the current leadership, the division has enjoyed significant growth to faculty and fellowship size, patient and procedural volume, and the federally funded research program.
