Pediatric Gastroenterology Fellowship

Training tomorrow's leaders

The primary goal of the Pediatric Gastroenterology Fellowship Program is to train academic pediatric gastroenterologists. We define academic gastroenterologists as those who are excellent clinicians encompassing skills in broad aspects of evaluation, diagnosis and management of primary and secondary diseases of the gastrointestinal tract and who are active in advancing the field by participating in research and/or education.

The first year of the program is devoted principally to clinical training, with both inpatient and outpatient activities and participation in an active consult service. The second and third years of the program are devoted primarily to laboratory and/or clinical research. An additional year may be added for training in clinical nutrition or advanced transplant hepatology.

Specific information by years and/or rotation

First year

Inpatient service

Goals: As described in the guidelines provided by the North American Society of Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN), the fellow should become competent in rendering age-appropriate inpatient care from evaluation to discharge of a broad range of primary and secondary gastrointestinal diseases, including intestinal mucosal diseases, motility disorders, hepatobiliary diseases, pancreatic disorders and functional problems from mouth to anus. Furthermore, the fellow should become competent in the performance of diagnostic and therapeutic invasive procedures. The fellow should learn to evaluate and ameliorate barriers to access for care and psychosocial impact of disease to utilize available ancillary services and deliver cost efficient care.

Objectives: The fellow will participate, with supervision from attending physicians, in all aspects of the care of patients of all ages hospitalized under the GI service at Children's Hospital of Philadelphia. This care includes initial evaluation, formulation of differential diagnosis and work up, participation in diagnostic procedures, interpretation of laboratory, radiologic, pathologic and other testing, treatment and discharge planning. The fellow will perform daily duties as described in the Fellows Handbook. The fellow will also participate in teaching residents and students on rounds and at the bedside as well as in didactic sessions. The fellow will attend all teaching conferences.

Outpatient service

Goals: As described in the NASPGHAN guidelines, the fellow should become competent in rendering age-appropriate outpatient care from evaluation through long-term follow up or discharge from clinic as indicated for each disease process. The fellow should provide care to patients with a broad range of gastrointestinal diseases including intestinal mucosal diseases, motility disorders, hepatobiliary diseases, pancreatic disorders and functional problems from mouth to anus. Additionally, the fellow should learn to evaluate and ameliorate the psychosocial impact of disease, utilize available ancillary services and deliver cost efficient care.

Objectives: The fellow will, with supervision from attending physicians, organize outpatient evaluation, diagnostic procedures and treatment, including hospital admissions as necessary. The fellow will perform history and examination, review of outside data and present cases to the attending physician as per the Fellows Handbook. The fellow will generate a clinic note and an associated letter to the referring physician.

Consult service

Goals: The fellow should become proficient in the evaluation of primary and secondary gastrointestinal signs and symptoms in infants and children hospitalized with non-GI disease. The fellow should be able to perform a complete history and examination and review any prior medical evaluation and testing (including discussions with other teams and review of pertinent radiology and/or pathology testing). Formulations and recommendations must be reviewed with the supervising attending physician and then communicated to the referring team and placed in the patient record in a timely and respectful fashion.

Objectives: The fellow will evaluate all patients as requested by any primary service at the Hospital. The fellow will present cases, write notes and communicate with the primary service as per the Fellows Handbook. The fellow will attend and make presentations in rotation at all teaching conferences.

Procedure service

Goals: The fellow should become increasingly proficient in the performance of various GI invasive procedures including patient assessment, sedation, procedural techniques and post-procedure monitoring and management. The fellow will ultimately develop skills to become independently proficient in diagnostic procedures such as upper and lower endoscopy, rectal suction biopsy, liver biopsy, paracentesis and manometry. The fellow will gain experience in additional diagnostic and therapeutic procedures, including capsule endoscopy, pH/impedance probe testing, esophageal dilation, sclerotherapy, banding and polypectomy.

Objectives: The fellow will review charts of scheduled outpatient procedures daily, will participate in the consent process, conscious sedation and/or collaboration with the general anesthesia team, the procedure, post-procedure management, communication with patients and families and generation of reports.

Additional rotations

Goals: The major goal of these rotations is to provide additional experience and insight into other specialties important to the evaluation and treatment of children with GI disorders, particularly Nutrition, Hepatology, short bowel syndrome (our Intestinal Rehab Program), Radiology, Pathology and Endoscopy.  The fellow will attend Continuity Clinic and participate in teaching conferences as allowed by the selective schedule.  Radiology and Pathology rotations are available by discussion with the program director.  


  • Nutrition — The first year fellow will spend a one-month (total) rotation on the Nutrition service and will participate in various nutrition clinics (cystic fibrosis, renal disease, weight management (obesity), home total parenteral nutrition, Feeding Team, etc.). The fellow will learn to perform nutritional evaluation, generate TPN formulations and interpret various nutritional tests, including bone densitometry, body composition testing and other specialized testing as determined by the nutrition service.
  • Hepatology — The first year fellow will spend one month (total) rotation on the Liver service and will participate in evaluation and management of all transplant recipients hospitalized for operative or subsequent admissions, inpatient consults related to liver transplantation, and outpatient hepatology clinic (including liver transplant evaluations). The fellow will observe any liver transplant surgeries that are performed. The fellow will gain a focused experience in pediatric liver disease and will attend hepatology conferences.
  • Intestinal Rehabilitation: Each fellow will spend 2 weeks total rotating on IRP service and will participate in a mix of inpatient and outpatient experiences designed to provide exposure and experience in the evaluation and management of children with intestinal failure.  Fellows will participate in new patient consultation, follow up consults, outpatient TPN rounds, conferences, and other activities as directed by the IRP attending.
  • Research Development: Each fellow will spend 1 week meeting with potential research mentors, meeting research teams, attending conferences or other activities to explore research opportunities in order to begin the process of choosing a research mentor/project.  In advance of this week, each fellow with meet with the Division Chief and Director of Research Training (at a minimum) to select potential mentors to visit.

Night and weekend call

Goals: The goal of night and weekend call is to provide the fellow with experience in the telephone triage of patients with acute changes in new or chronic illness and to provide training in cross-covering inpatients.

Objectives: The fellow will obtain sign-out information from the inpatient and/or consult fellow as applicable prior to taking on-call responsibilities. Responsibilities are described in the Fellows Handbook.

First-year clinical rotations

  • Approximately 13 weeks inpatient service
  • Approximately 13 weeks consult service
  • Approximately 13 weeks procedure/consult service
  • Four weeks Nutrition
  • Four weeks Hepatology
  • Four weeks of vacation
  • One-half day a week dedicated to the outpatient clinic

Second and third years

Research experience

Goals: Each fellow will undertake a specific project or projects — under the direct guidance of a research mentor — with the goal of significant participation in research. This is one of the requirements of the American Board of Pediatrics for certification in Pediatric Gastroenterology, the NASPGHAN guidelines and our program goal to produce graduates who will become academic gastroenterologists. The division chief, program director and director of research training will assist each fellow in the selection of an appropriate project and mentor.

Objectives: The specific objectives of each project will vary greatly depending on the project selected and the mentor chosen. The long-term goal is for each fellow to submit for publication at least one manuscript related to the research experience. It is expected that fellows will have significant participation in designing the project, interacting with the appropriate regulatory committees, performing studies, analyzing data, and writing a related manuscript. The fellow will attend project specific national/international conferences as recommended by the mentor as well as the standard clinical GI conferences.  Fellows will meet twice per year with their scholarship oversight committee (SOC) to provide updates on projects, share data, and receive feedback on progress of their research.
