At Mount Sinai, our pediatric gastroenterology specialists are dedicated to providing compassionate and comprehensive family-centered care to infants, children, and teens with digestive problems. Listed among the country’s top children’s hospitals for Pediatric Gastroenterology and GI Surgery in the U.S. News & World Report® Best Children's Hospitals 2024-25 rankings, our team has expertise in a wide variety of digestive nutritional disorders including inflammatory bowel disease (Crohn’s disease and ulcerative colitis), celiac disease, abdominal pain, constipation, gastroesophageal reflux disease, and feeding problems.

As our patients become young adults, we also work closely with our colleagues in adult gastroenterology to facilitate transition of care to our adult programs.

Special Programs

We offer several special programs to diagnose and treat common gastroenterological conditions in children.

The Pediatric Inflammatory Bowel Disease (IBD) Program aims to optimize care for young children and teens who struggle with IBD (including Crohn’s disease and ulcerative colitis). Our program is one of the largest in the country. We provide diagnostic evaluations, second opinions, and ongoing services to help families support children living with IBD.

At The Susan and Leonard Feinstein Inflammatory Bowel Disease (IBD) Clinical Center, we provide the full gamut of IBD services. Our multidisciplinary team includes pediatric gastroenterologists, nurse practitioners, social workers, nutritionists, and a clinical psychologist. We develop a personalized treatment plan for your child with IBD, to help him or her lead a normal, productive life. With the adult and pediatric programs under one roof, we have an important opportunity to conduct comprehensive research and collaborate to offer the most advanced treatments to help your child. We can also seamlessly transition your child into our adult IBD program at the appropriate time.

The Henry and Elaine Kaufman Intestinal Ultrasound Program is the first of its kind in the United States to offer non-invasive, point-of-care, monitoring for children with IBD. By eliminating the need for bowel preparation, fasting, and the use of oral or intravenous contrast agents, we can monitor inflammation and healing of the intestines with ultrasound in a highly accurate way which does not cause any pain or harm to your child. We believe this will become the standard of care for IBD monitoring, and as such, have become global leaders in both translational research and the educational training of pediatric gastroenterologists from outside hospitals to improve care for all children with IBD. 

The Pediatric Small Intestinal Rehabilitation and Transplant Program works closely with our small intestinal surgeons to provide comprehensive medical and surgical management for a wide variety of diseases including short gut and intestinal failure.

Program for Upper Gastrointestinal Tract Disorders and Diseases includes comprehensive programs that optimize the treatment of disorders and diseases affecting the esophagus, stomach and small bowel:

• The Pediatric Celiac Disease Program offers medical and nutritional management along with psychosocial support for patients with celiac disease and their families.
• Pediatric Aerodigestive Program is an interdisciplinary program including GI, ENT, pulmonary, complex care pediatricians, speech language pathologists, dieticians and nurses to provide comprehensive coordinated care for children with complex conditions of the upper airway, GI, and pulmonary systems.
• Pediatric Eosinophilic Disorder Program offers medical and nutritional management of eosinophilic esophagitis and eosinophilic gastroenteritis. We work in close coordination with our world-class food allergists to provide optimal care for children with these disorders.
• Pediatric Esophageal Motility Disorder Program offers motility studies of the upper gastrointestinal tract including ph and impedance monitoring.

Pediatric Gastroenterology Services provides complete diagnostic and treatment services to our young patients.

Supporting Team IBDkids: The New York City Marathon

Every November, our Children’s IBD Program fields a team of runners in the TCS New York City Marathon, one of the world’s most-attended marathons, to increase awareness about pediatric IBD and raise money to support our program’s research and family-centered, comprehensive care. Our runners have included parents of patients, siblings of patients, and family friends as well as physicians, medical students, and biomedical research scientists. Some runners have IBD themselves. We have even had a few patients, who were treated in our program as children or teens, run the marathon to support Team IBDkids.

Team IBDkids is able to guarantee entry for a limited number of runner-fundraisers. For more information on running with Team IBDkids, contact PEDSGI@mssm.edu.

If you want to help but you do not want to run 26.2 miles, you can help by becoming an event sponsor, sponsoring a runner, or coming out to cheer on Team IBDkids. E-mail PEDSGI@mssm.edu for more information.
