AGA presents cutting-edge research during DDW

Clinicians, researchers and scientists from around the world will gather for Digestive Disease Week (DDW) 2011, the largest and most prestigious gastroenterology meeting, from May 7-10, 2011, at McCormick Place, Chicago, IL. DDW, which is jointly sponsored by the American Association for the Study of Liver Diseases, the American Gastroenterological Association (AGA) Institute, the American Society for Gastrointestinal Endoscopy and the Society for Surgery of the Alimentary Tract, is the annual meeting of the AGA Institute.

AGA researchers will present exciting, cutting-edge data during the meeting that will help change the way physicians diagnose and treat GI disorders. All data presented during DDW is embargoed until the beginning of the presentation or an official DDW press conference, whichever occurs first. A list of press conferences is available at

Rome Foundation-AGA Institute Lectureship

Tarique Perera, MD, assistant professor in clinical psychiatry, will join Michael D. Gershon, MD, professor of pathology and cell biology, to bring their unique perspectives to a discussion that will include a look at the possibility of reversing functional GI disorders with serotonin agents. Both internationally renowned experts teach at Columbia University in New York. During Sunday's fifth annual Rome Foundation-AGA Institute Lectureship (May 8, 10:30 a.m. CT, Room E451A), these experts will provide a comprehensive overview of The Role of Neurogenesis in the Brain and Gut and its Implications for Functional GI and Motility Disorders. Co-chairs Lin Chang, MD, AGAF, and Douglas A. Drossman, MD, AGAF, agreed that bringing these experts together is a way to harmonize the knowledge from investigators in two different areas but on the same process. "This lecture will provide cutting-edge science with many potential practical and clinical implications," said Dr. Drossman.
