Gastroenterology Division Campuses

Mount Sinai Beth Israel

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 internally recognized faculty delivers clinical care at Mount Sinai Beth Israel. 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 imagining technology and collaborate with excellent colleagues in colorectal surgery, pancreatic surgery and oncology. This environment 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.

The Mount Sinai Hospital

The mission of the Dr. Henry D. Janowitz Division of Gastroenterology is excellence in the delivery of patient care, research, and education in disease of the GI tract. The division is heir to a great tradition. Eminent physicians, surgeons, radiologists, hepatologists, and pathologist have provided a rich body of knowledge in the diagnosis and management of inflammatory bowel disease, peptic ulcer disease, esophageal disorders, gastrointestinal cancer, and liver, biliary, and pancreatic diseases. Mount Sinai has been on the forefront of research, identification, and treatment of gastrointestinal illness since the division’s early days. Today, through cutting-edge research, advanced therapeutic treatments and rigorous education of our fellows, the division is spearheading discoveries that will advance science and improve patients’ lives.

Mount Sinai Morningside and Mount Sinai West

Our division maintains a busy gastroenterology and hepatology service for the diagnosis and treatment of diseases and disorders of the esophagus, stomach, colon, liver and other organs of digestion. Conditions treated included inflammatory bowel disease (ulcerative colitis and Crohn’s disease), peptic ulcer disease, gastro-esophageal reflux disease, chronic diarrheal disorders, liver and biliary disease and cancers of the digestive tract. Facilities include the newest state-of-the-art modern endoscopy suites for diagnosis and treatment.

Our division has an outstanding fellowship training program with fellows rotating through services at the Mount Sinai Morningside and Mount Sinai West Hospitals. Additionally, active clinical research programs are ongoing with support of the National Institutes of Health and other agencies. These programs involve studies of colon cancer prevention, gastric H. pylori infections and effect of aging upon gastrointestinal function and the nutritional management of chronic diseases which affect the liver and gastrointestinal tract such as HIV infection and chronic liver disease, and studies of the assessment of metabolism in these conditions.
