Gastroenterology Fellowship

A message from David L. Carr-Locke, MD, FRCP, FASGE Chief of the Division of Digestive Diseases

The Division of Digestive Diseases is devoted to the quality care of patients, clinical research in disorders of the gastrointestinal tract and liver, and the training of physicians in the diagnosis and treatment of patients with gastrointestinal disorders.

Our mission is to deliver outstanding gastroenterology care to the community of New York City and the surrounding metropolitan area. We aim to make scientific discoveries that will improve gastrointestinal health for all patients through research efforts in clinical gastroenterology, endoscopy, hepatology, and pathology.

The Division's nationally and internationally-recognized faculty delivers clinical care at Mount Sinai Beth Israel- Petrie Division in Manhattan. Our diverse patient population presents us with a large spectrum of pathology and challenging cases. We are privileged to house state-of-the art endoscopic and imaging technology and collaborate with excellent colleagues in colorectal surgery, pancreatic surgery, and oncology. This milieu provides a unique opportunity for performing clinical research and for training the next generation of gastroenterologists in our fellowship program. Faculty members in the Division have a wide range of special research interests, including inflammatory bowel disease, gastrointestinal cancer, disorders of the pancreas and bile duct, liver disease and therapeutic gastrointestinal endoscopy.



Goals, Objectives & Educational Purpos

The Fellow will:

  • Gain an understanding of the anatomy, physiology and pathology of gastrointestinal and liver diseases.
  • Acquire a detailed fund of knowledge regarding the natural history, prevention, diagnosis and treatment of the major diseases of the esophagus, stomach, small intestine, colon, pancreas, gall bladder, liver and biliary tree.
  • Learn how systemic and vascular diseases manifest in the gastrointestinal tract.
  • Develop the clinical skills necessary to identify and evaluate patients with gastrointestinal, pancreatic and liver diseases.
  • Become proficient in the management of gastrointestinal and liver diseases encountered in hospitalized patients and outpatients.
  • Gain competence in a variety of procedures including diagnostic and therapeutic endoscopy, biopsies (mucosal and liver) and motility studies.
  • Have a thorough grounding in the principles, application and interpretation of imaging of the digestive tract.
  • Acquire a detailed fund of knowledge of the various classes of drugs and vaccines used in gastroenterology including sedation and sedative pharmacology.
  • Understand the importance of nutrition, malnutrition and enteral and parenteral feeding.
  • Develop skills necessary to design, conduct and evaluate research in gastroenterology.
  • Complete a research project leading to a publication in a peer-reviewed journal.
  • Adopt a critical approach to the literature pertaining to gastroenterology and hepatology.
  • Integrate health promotion, and cultural, socioeconomic, ethical, occupational, environmental, and behavioral issues with medical care.
  • Incorporate humanistic health care and patient values at all times.


Clinical Rotations
The clinical rotations include inpatient, outpatient clinics, liver transplant, and endoscopy. The program is reviewed periodically and subject to modification.

Inpatient rotation – Petrie Division
All inpatient rotations are at Mount Sinai Beth Israel. First year fellows will rotate on this service throughout the year. This includes the GI Inpatient Service to which patients of full-time faculty or from GI/liver clinics are admitted. The GI/liver Consult Services are also managed by first year fellows. The service is staffed by a faculty who conducts daily rounds with fellows and residents.

Outpatient rotations- Phillips Ambulatory Care Center/Center for Digestive Health
During all years of the fellowship, the fellow will spend one half-day in GI clinic and one half-day in Liver clinic each week under the supervision of a faculty member. In addition, the 1st and 2nd-year fellows attend another half-day session for a total of about 6 months a year. Outpatients are seen in the Phillips Ambulatory Care Center at 10 Union Square East, Suite 2G or at the Center for Digestive Health at 37 Union Square West- 4th floor office.

Endoscopic training
Fellows will be trained in diagnostic/therapeutic upper endoscopy, diagnostic/therapeutic colonoscopy, sigmoidoscopy, percutaneous endoscopic gastrostomy tube placement, sclerotherapy, and band ligation. There is ample opportunity to learn the basics of endoscopic ultrasound (EUS), and ERCP. The therapeutic endoscopy fellow will perform EUS and ERCP under direct supervision. The endoscopy unit is located at BI Petrie, 8 Dazian.

Liver transplant – New York University Medical Center
During the second or third year of fellowship, the fellow will rotate for 6 weeks at the New York University Liver Transplant program under Dr. Lewis Teperman.

Advanced Endoscopy Fellowship
An Advanced Endoscopy fellowship is available to candidates who have completed three years of categorical gastroenterology fellowship. The Advanced Endoscopy fellow will be trained in EUS, ERCP, enteroscopy, stent therapy, endoscopic mucosal resection (EMR), and confocal endomicroscopy


Fellows are expected to attend all conferences, which include the weekly GI Grand Rounds, monthly Journal Club, GI Research Conference, and Morbidity and Mortality conferences. Multidisciplinary Hepatopancreaticobiliary and Inflammatory Bowel Disease Conferences are shared with colleagues in surgery, pathology, and radiology. Bimonthly Chief of Service Rounds is also conducted. Fellows will also participate in the "Didactics in Pathophysiology Seminar", a comprehensive series of talks given by GI fellows under the supervision of an attending physician.
