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.

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.
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.
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.
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.
