Welcome to the Division of Gastroenterology and Hepatology. We are part of Penn Medicine, an integrated organization that includes the University of Pennsylvania Perelman School of Medicine and the University of Pennsylvania Health System. Since the development of the Division in 1926, it has been one of the premier centers in the world for digestive and liver research, education, and clinical care. Our mission is that together we will pursue excellence in the care of individuals with digestive and liver diseases, excellence in the education of the next generation, and to seek innovative solutions to digestive and liver diseases. Our purpose is to enrich the lives of patients with GI and liver disease by leveraging our research, educational, and clinical excellence to challenge our current approaches.

Today, we are a vibrant and large Division with over 75 physicians, 24 fellows and over 200 staff across several sites that include the Hospital of the University of Pennsylvania, Perelman Center for Advanced Medicine, Penn-Presbyterian Medical Center, Pennsylvania Hospital, Penn Medicine at Radnor, and the Corporal Michael J. Crescenz VA Medical Center. There is close collaboration with the Children’s Hospital of Philadelphia.

The Division provides clinical care in programs dedicated to General Gastroenterology, Inflammatory Bowel Disease, Neurogastroenterology and Motility, Esophagus, Advanced Interventional Endoscopy, General and Transplant Hepatology, Gastrointestinal Genetics and Nutrition. We are fortunate that these programs are staffed by internationally recognized faculty.

The education of the next generation is an important aspect of our mission. Our gastroenterology fellowship is supported by 2 NIH T32 grants, one for basic science and the other in clinical epidemiology. We offer a clinical gastroenterology fellowship as well, and our faculty are leaders in the education and training of future gastroenterologists.

Our research program has grown over the years and our total sponsored program awards were an impressive $20 million for fiscal year 2024. The centerpiece of our research program is our NIH/NIDDK P30 UPenn Center for Molecular Studies in Digestive and Liver Diseases, one of only 17 in the nation. Our faculty continue to make discoveries that challenge current paradigms.

I hope that you continue to learn about our storied Division, and more importantly, I am truly excited about our future.

Division of Gastroenterology today

The Division of Gastroenterology and Hepatology in the Department of Medicine at Penn is a robust academic unit, with 75 full-time faculty members whose clinical and scientific expertise covers the spectrum of areas within modern gastroenterology. There are 25 fellows in training and more than 200 staff members across five primary sites, the Hospital of the University of Pennsylvania, Penn-Presbyterian Medical Center, Pennsylvania Hospital, the Hospital of the University of Pennsylvania-Cedar Avenue, and Penn Medicine at Radnor.

The clinical focus of the Division includes inflammatory bowel disease (IBD), Hepatology and liver transplantation, gastrointestinal oncology, gastrointestinal motility and physiology, esophagology, nutrition, advanced interventional endoscopy, and general gastroenterology. In recent years the Division has seen robust growth in the number of patients awaiting liver transplantations and obtaining liver transplants; increased numbers of endoscopic procedures in the setting of a rigorous quality assurance program; and an increasingly complex mix of GI and Hepatology subspecialty consultations in IBD, upper GI disorders, nutrition, and motility/physiology from local, regional and national referral partners. The division includes a significant health systems research group and has been a leader in the development of innovative approaches to providing care.

The Division participates actively in the education and training of undergraduate students, medical and graduate students, combined degree students, medical residents, and GI/Hepatology fellows and advanced fellows. The fellowship is supported through two NIH T32 training grants, one in basic sciences and the other in clinical epidemiology. Medical students are encouraged to participate in both basic science and clinical curricula, as are undergraduates; the division holds two NIH R25 training grants for undergraduates, one for bench research training and one for epidemiology training.

Sponsored program awards and proposals have grown impressively over the years. Among the GI faculty of 75 members, there are 19 physician-scientists and research faculty engaged in NIH-funded research, and many of the clinician-educators have funded research programs.  Total sponsored programs awards were over $20 million in FY24, impressive in this current competitive funding environment.  The Division has witnessed the rapid emergence of multidisciplinary research-funded efforts that have nurtured collaborative relationships across the Penn campus and worldwide. Within the Division and beyond, GI and Hepatology research at UPenn is supported by the NIH/NIDDK UPenn Center for Molecular Studies in Digestive and Liver Diseases (P30), co-directed by Gary Wu, MD (Division of Gastroenterology and Hepatology) and Klaus Kaestner, PhD (Department of Genetics). The center, one of only 17 in the United States, includes more than 40 members and associate members coming from five schools at the University of Pennsylvania as well as the Corporal Michael J. Crescenz VA Medical Center and the Children’s Hospital of Philadelphia. It provides access to research core facilities, an annual symposium, weekly research seminars, and other enrichment events.
