The Gastroenterology and Nutrition Service of the Department of Medicine at Memorial Sloan Kettering Cancer Center offers a three-year Gastroenterology Fellowship Training Program that combines an outstanding experience in patient care and education. The fellowship also provides clinical and basic research opportunities.

We are currently accepting applications for our GI Fellowship Program. Our program participates in the GI Match, through the National Residency Matching Program (NRMP). To register for the NRMP, please visit the National Resident Matching Program Web site.

Fellows in the Gastroenterology and Nutrition Service benefit from our Service’s strong and longstanding relationships with the Departments of Surgery, Medical Oncology, Radiology, Biostatistics/Epidemiology, and Human Genetics. There are combined multidisciplinary conferences, shared clinical care, and substantial research opportunities.

The Gastroenterology and Nutrition Service consults on and manages all clinical problems within the full spectrum of benign and malignant gastrointestinal and hepatobiliary diseases. In addition to our excellent international reputation in gastrointestinal oncology, our group has a strong interest and commitment to general gastroenterology, hepatology, endoscopy, and nutrition.

We see a large number of patients each year for clinical care and research programs. The Gastroenterology and Nutrition Service currently provides approximately 4,000 outpatient visits, over 2,000 inpatient consultations, approximately 5,000 endoscopy procedures, and over 6,500 nutrition treatment days.

Endoscopy procedures are performed in our state-of-the-art Gastroenterology Endoscopy Unit, located in our Surgical Day Hospital. We perform the full range of GI procedures, which include upper gastrointestinal endoscopy, dilatation, colonoscopy, polypectomy, ERCP (diagnostic and therapeutic), percutaneous gastrostomy and jejunostomy, small bowel enteroscopy, laser therapy (Nd:YAG and PDT), percutaneous liver biopsy, and endoscopic ultrasonography. The GI Endoscopy Unit supports a number of important clinical investigative projects. Our GI fellows develop expertise in all of the major endoscopic procedures during the course of their three-year fellowship training.
