Gastroenterology, Hepatology & Nutrition
Our objective at the Division of Gastroenterology, Hepatology and Nuturition (GHN) is to brighten the future for children with GHN disorders, through:
- Excellent, safe and innovative clinical care
- Cutting edge research
- World class training for the next generation of subspecialists
We maintain an international reputation as one of the world’s leading academic paediatric GHN centres of excellence.
The University of Toronto fellowship training program in paediatric gastroenterology, hepatology and nutrition is by far the largest in Canada and comparably sized to the premier training programs in this subspecialty in the United States
The Division of Gastroenterology and Nutrition hosts 12 full-time staff and three associate staff.
What we do
Our goal is to provide high quality clinical care using an evidence-based approach whenever possible. All of the medical staff in the division are qualified to provide specialized care in their areas of expertise as well as in general GI, hepatology and nutrition.
The division is organized into three inpatient sections and our ambulatory program. The inpatient sections include: liver and small bowel transplantation (on ward 6A); general GI, nutrition and hepatology (on ward 6A); and a consultation team which provide consultative services across the hospital. We run a procedure facility on ward 4C for diagnostic and therapeutic endoscopy, biopsies, probes and manometry. This facility services both our inpatient as well as our ambulatory program.
Our ambulatory program has specialty clinics in cystic fibrosis, dysphagia, hepatology, IBD, general gastroenterology and nutrition. We manage patients on home – total parenteral nutrition (TPN), and home enterostomy feeding. The clinics are run as multidisciplinary teams, including nurses, clinical nurse specialists, dietitians, social workers and physicians.

Our research spans the spectrum from basic and translational to patient-based in such areas as cystic fibrosis, inflammatory bowel diseases, nutrition and hepatology. Funding support (over $2 million dollars annually) presently includes grants from the CIHR, NIH, CF Foundation, Crohn’s and Colitis Foundation, the HJ Heinz Co. Foundation, Canadian Digestive Health Foundation.
The University of Toronto Training Program in Paediatric Gastroenterology, Hepatology and Nutrition is based at The Hospital for Sick Children (SickKids) and maintains a strong tradition of training clinicians from all over the world for academic careers encompassing research, education and clinical care. The training program is the largest in Canada and comparably sized to the premier training programs in this subspecialty in the United States.
The training program is fully accredited in Canada, by the Royal College of Physicians and Surgeons. Training in Toronto is also fully recognized by the American Board of Pediatrics in the USA, and the Royal Australasian College of Physicians in Australia and New Zealand.
The core fellowship program follows a three-year structure with one clinical year followed by two research-focused years. Previous trainees who have completed the three-year fellowship program have been extremely successful in obtaining high caliber academic and leadership positions in Canada, the United States and around the world. Graduates of the program typically continue research activities and hold extramural grants to support their research programs.
We also offer one-year clinical training fellowships and subspecialty fellowship programs for advanced trainees who have completed the majority of their core training in Gastroenterology, Hepatology and Nutrition elsewhere.
Expand each section below to see important details.
During the first year of training, trainees are exposed to a large variety of clinical cases and to all aspects of ambulatory and inpatient paediatric gastroenterology, hepatology & nutrition (GHN). Trainees have a unique opportunity to engage in cutting edge medicine and state of the art clinical care. Clinical care is provided in an academic environment using an evidence-based approach under ongoing staff support and supervision.
During the first clinical year, trainees will rotate through the following services:
- General GHN inpatient service - general GI, IBD, non-transplant liver disease, feeding disorders, motility disorders and pancreatic disorders (usual census 6-12 patients).
- Transplant service – liver and intestine transplantation, acute liver failure and end stage liver disease (30-35 liver transplants annually; usual census 5-10 patients).
- Consult service – consultation services to the hospital in-patient wards and to community-based practitioners
- GIFT service – intestinal failure training (usual census 5-8 patients).
- Adult gastroenterology – one month of adult gastroenterology and endoscopy training.
- Outpatient clinics – general GI and specialized clinics in IBD, hepatology, nutrition, motility disorders, celiac, intestinal failure, liver transplantation, pancreatic diseases and other.
- Paediatric procedures – upper and lower endoscopies, variceal band ligation, polypectomy, foreign body removals. Each trainee performs 150-200 pediatric procedures during the first year of training.
Overnight and weekend on-call coverage for patients admitted to the GHN and transplant inpatient services is provided by core fellowship trainees during their three years of training. Trainees provide call from home and provide support for general paediatrics residents who remain in hospital overnight. Trainees may need to come to the hospital during their call. Call frequency is roughly one night each week and one weekend each month.
Salary support is available on a competitive basis from either the Ontario Ministry of Health and Long-Term Care (for Canadian trainees) or SickKids (for international trainees for the first two years of training). Third year funding is obtained on a competitive basis through supervisor, divisional, hospital or extra-mural sources. Traditionally all of our research trainees successfully obtain salary support from these sources for their last year of research training.
The second and third years of the Core Fellowship Program are primarily focused on research training. There are a vast number of opportunities for high caliber clinical, translational or basic science research within the division, within the SickKids Research Institute and at the University of Toronto. The Research Institute (RI) is the largest hospital-based research program in Canada, and is among the largest paediatric research programs in the world.
The multidisciplinary structure of the RI encourages collaborative research, as does its new home in the Peter Gilgen Centre for Research and Learning. Areas for research training are chosen by discussion between the trainee and potential supervisors, according to the interest of the trainee and the interests and expertise within our division and the RI.
Specific areas of research within the division include basic science, clinical and translational science, epidemiology and education.
Trainees can undertake a postgraduate degree program (M.Sc, M.Ed, PhD) offered at the University of Toronto (e.g., programs in Institute of Health Policy, Management and Evaluation, Institute of Medical Sciences, Ontario Institute for Studies in Education, Department of Physiology or Department of Pathology Laboratory Medicine) or distance education programs offered by other Universities. A substantial number of trainees (50 per cent over the last decade) have pursued concurrent degrees during their research training.
The GI training program at SickKids provides opportunities for advanced clinical and research training in specific domains of paediatric gastroenterology. The advanced subspecialty fellowship training programs include inflammatory bowel disease, hepatology /liver transplantation and intestinal failure. Expand the sections below for additional details.
Inflammatory Bowel Disease - (IBD)
A one-year advanced IBD clinical and research training fellowship is available for interested trainees and is supported through the SickKids IBD Centre.
Canada has among the highest incidence rates for IBD worldwide. Ontario health administrative data suggest that the incidence is continuing to increase, particularly in children. IBD care is centralized within the Gastroenterology, Hepatology and Nutrition (GHN) Division, such that three IBD specialists provide ambulatory care in six “half-day” IBD clinics weekly with over 2000 patient visits annually. IBD patients also account for the majority of inpatient days on the “GHN” ward. Ten to twelve patients are newly diagnosed each month and remain under follow-up care until the time of transfer to adult care by age 18 years. The SickKids IBD Program is hence responsible at any given time for the care of 900 children and adolescents with Crohn’s disease and ulcerative colitis, making it one of the largest paediatric IBD programs worldwide.
The IBD ambulatory program includes three specialty clinics. Dr. Alex Muise, co-lead of the international NEOPICS consortium, which has been very successful in identifying monogenic forms of IBD, runs a very-early onset IBD clinic. There is an alternate weekly “anti-TNF” therapy clinic exclusively for patients being treated with biologics, and a periodic joint clinic with Drs. Ling and Kamath, for the care and study of patients with PSC-IBD.
All fellows in the GI/Hepatology/Nutrition training program are given multiple opportunities for small group learning including new patient IBD rounds, challenging IBD patient rounds, IBD teaching rounds for fellows, and Magnetic Resonance Imaging rounds, all held once in every two weeks.
The IBD program aspires always to integrate state of the art clinical care with meaningful patient-based and translational research. The program has had remarkable opportunities to train the next generation of paediatric IBD specialists, and in networking internationally to advance IBD research and clinical care. The Canadian Children IBD Network: a joint partnership of CIHR and the CH.I.L.D. Foundation is led by the SickKids IBD program.
Group for Improvement of Intestinal Function and Treatment - (GIFT)
Advanced training in intestinal failure and rehabilitation is provided by the SickKids intestinal rehabilitation program (GIFT – Group for Improvement of Intestinal Function and Treatment). The GIFT program is the largest of its kind in Canada and one of the leading intestinal rehabilitation programs in the world with 20 to 25 new patients every year. The program follows a large variety of patients with intestinal failure ranging from short bowel syndrome to severe motility disorders and congenital diarrheas in an inpatient and outpatient setting. The inpatient service is an independent service with daily census of 5 to 10 patients / day. A multi-disciplinary team of paediatric gastroenterologists, paediatric surgeons, nurses, dieticians, physiotherapists, oral therapists, social workers and others provide comprehensive daily care. Clinical, translational and basic research is an integral part of the program activities and multiple opportunities exist for interested trainees under the supervision of Dr. Paul Wales, general surgery, and Dr. Yaron Avitzur, paediatric gastroenterology.
Intestinal failure training is focused on clinical and research training in the field of intestinal failure and rehabilitation. Training is offered for a one year period for fully trained general gastroenterologists or general surgeons and is recognized by the University of Toronto. Funding is provided on a competitive basis through SickKids Transplant Centre.
Hepatology and Liver Transplant
Advanced training in paediatric hepatology and liver transplantation is provided by the Division of Paediatric Gastroenterology, Hepatology and Nutrition and the Liver Transplant program at SickKids*.
Our one-year program provides flexible training to meet the needs of each individual fellow, whether their focus is advanced hepatology training, training in liver transplantation, or research training. Our overall aim is to train the future leaders in this field across the world. SickKids currently performs between 25 and 40 paediatric liver transplants per year, and has completed more than 500 paediatric orthotopic liver transplants, including over 150 from live donors, since the first SickKids paediatric liver transplant in 1986. Our clinical service includes four paediatric hepatology clinics, a liver transplant clinic each week and a busy inpatient liver transplant service. We work closely with our partners at the University of Toronto Transplant Institute and Toronto Liver Centre.
During this year of training, the Hepatology and Liver Transplant Fellow will gain clinical mastery in a wide range of general acute and chronic liver conditions, including care of patients with neonatal cholestasis, abnormal liver tests, end-stage liver failure, fulminant liver failure, hepatic neoplasms, metabolic liver conditions, portal hypertension, viral hepatitis, biliary diseases, vascular malformations of the liver; diagnosis of immune-mediated liver diseases and cholestasis syndromes; assessment of the candidacy of patients for liver transplantation; management of paediatric patients pre- and post-liver transplantation; and long-term post-liver transplantation care. Fellows will interact closely with subspecialists in other divisions, including critical care medicine, interventional radiology, pathology, metabolic genetics, and transplant surgery. Fellows will develop diagnostic and therapeutic expertise in areas of hepatology and nutritional disorders and develop proficiency in the performance of diagnostic and therapeutic procedures (ie. endoscopic variceal band ligation); observation of procedures (including liver transplantation, percutaneous cholangiography), and non-transplant hepatobiliary surgeries (including Kasai portoenterostomy, partial external biliary diversion, shunt surgery); interpretation of liver histopathology; organizational structure and administration of a liver transplant program.
Clinical, translational and basic research is an integral part of the program activities and multiple opportunities exist for interested trainees under the supervision of faculty hepatologists within the Division of Paediatric Gastroenterology, Hepatology, Nutrition and Liver Transplantation to complete a mentored concise clinical or translational research project.

The Division of Gastroenterology, Hepatology and Nutrition is a world-class academic program, which has established a superlative national and international reputation for its achievements in clinical and laboratory based research, postgraduate training and clinical care.
Prior to 1994, the division was comprised of two distinct entities, namely the Division of Gastroenterology and the Division of Clinical Nutrition.
The Division of Gastroenterology was first established in the 1960's, under the able leadership of Drs. Andrew Sass-Kortsak and J. Richard Hamilton. The Division quickly emerged as a world-class, academically focused leader of the sub-specialty.
The Division of Clinical Nutrition was established under the leadership of Dr. Paul Pencharz, who was recruited in 1978 to clearly delineate and establish clinical nutrition as a medical/surgical discipline at SickKids.
Both former divisions adopted an “integrated” academic model with combined clinical, educational and academic goals and objectives; thus, the former Division Chiefs of each division assumed combined responsibilities under the umbrella of the Department of Paediatrics and the Research Institute. In 1993, the two divisions were amalgamated under the leadership of Dr. Peter Durie.
