Gastroenterology, Hepatology & Nutrition

The fellowship program in Pediatric Gastroenterology, Hepatology and Nutrition is a 3-year, ACGME-accredited program committed to training the next generation of academic pediatric gastroenterologists. The program provides a broad clinical experience in outpatient and inpatient medicine, excellent procedural training, in- depth didactics as well as outstanding environments for research. Fellows consult on a broad range of clinical gastroenterological problems including inflammatory bowel disease, cystic fibrosis, celiac disease, liver disorders, liver and small bowel transplantation, intestinal rehabilitation and nutritional disorders. Trainees benefit from the diverse clinical population seen at a major referral center, with consultations ranging from outpatient referrals to the quaternary level inpatient service. Numerous clinical and research conferences provide the strong didactics that are necessary for up-to-date clinical care and research training.

In addition to gaining proficiency in outpatient and inpatient pediatric gastroenterology, extensive procedural training is also offered in upper endoscopy, colonoscopy, polypectomy, biopsy techniques of the intestine, cauterization and injection of bleeding sites, sclerotherapy, band ligation, percutaneous gastrostomy tube placement, liver biopsy, intestinal stricture dilatations, foreign body retrieval. esophageal impedance, and functional manometry.

Research is an emphasized component of the training experience, and Columbia University offers a wealth of research opportunities. Fellows are expected to participate in both clinical and translational investigative projects and to produce high quality research during their research years under the close supervision of an established faculty mentor. Regular committee meetings are organized to monitor and aid in the progress of fellow research endeavors. We currently have two fellows supported by Pediatric Scientist Development Awards from the American Medical School Pediatric Department Chairmen, with funding from NICHD.

The goal of the training program is that by the completion of the three years of training the fellow will have received excellent clinical and procedural training as well as the strong research background necessary to pursue a career as an academic gastroenterologist.
