Pediatric Gastroenterology Fellowship of the National Capital Consortium


The Pediatric Gastroenterology Fellowship program is fully accredited by the ACCME and designed to prepare physicians for careers in either clinical or academic pediatric gastroenterology.  It consists of three years of post-graduate medical education, which includes both clinical and research experience.  Applicants must have completed or anticipate successful completion of a pediatric residency, including at least one year of pediatric internship and two years of pediatric residency, and be either board certified or eligible to sit for the certifying examination in general pediatrics.  

The fellowship consists of 12 months of clinical service and 24 months in which to design and implement a basic science or clinical research project. An ongoing series of clinical and didactic conferences completes the fellowship curriculum. The attending pediatric GI service staff is augmented by a pediatric radiologist, a pediatric surgeon, a pathologist, A GI motility and research technician, two nutritionists, a pediatric nurse practitioner and an endoscopy technician. Fellows are required to participate in the design and implementation of a research project. In addition to the clinical research opportunities afforded by the diversity of patients, basic science research opportunities exist at the Uniformed Services University of the Health Sciences, Walter Reed Army Institute of Research, Walter Reed National Military Medical Center Bethesda, and the University of Maryland.

Active duty in one of the Uniformed Services of the United States (Army, Navy, Air Force, Public Health Service) is required. Information on incurred obligations, pay and allowances may be obtained from the Office of Graduate Medical Education.  Applicants must apply through and be sponsored for postdoctoral training by the Graduate Medical Education office of their respective branch of service. Requests for training should list the Pediatric Gastroenterology Fellowship Program of the NCC at USUHS as their site of choice. Application deadlines are usually in September and are determined by the individual services. Where feasible applicants are encouraged to visit the USUHS and Walter Reed facilities and arrange personal interviews with faculty members. If a visit is not practical, applicants should contact the program director and submit an updated CV and letter of intent. Telephone inquiries are welcomed (301) 295-3130.


The fellowship program comes under the umbrella of the Uniformed Services University of the Health Sciences (USUHS), and the National Capital Consortium (NCC), a military Graduate Medical Education organization, and has been training fellows since 1978.  The pediatric gastroenterology fellowship is closely allied with the fellowship in adult gastroenterology at Walter Reed National Military Medical Center at Bethesda (WRNMMC). This program consists of 12 board-certified gastroenterologists. They offer an impressive resource of research knowledge and productivity as well as clinical expertise. The fellows and staff in the pediatric gastroenterology program participate in a number of joint conferences with this group. These include a weekly clinical conference, weekly grand rounds, weekly physiology conference and monthly city-wide GI grand rounds.

Clinical Experience

The clinical experience provides intensive exposure to all aspects of the practice of pediatric gastroenterology, including inpatient and outpatient evaluation of patients with a wide diversity of conditions. The pediatric GI service performs approximately 350 procedures annually including upper endoscopies, esophageal stricture dilations, esophageal motility studies, foreign body extractions, intraesophageal pH monitoring, breath hydrogen studies, gastric and small intestine biopsies, intestinal intubations, percutaneous endoscopic gastrostomies, percutaneous liver biopsies, colonoscopies, colonic and ileal biopsies, colonic polypectomies, sigmoidoscopies, anorectal manometries, and rectal biopsies. Interventional management of upper and lower GI bleeding, balloon dilatations, variceal sclerotherapy, and ERCP capability are performed with the support of the adult gastroenterology staff. Endoscopic procedural and teaching capabilities are enhanced by a dedicated pediatric endoscopy unit equipped with a state-of-the-art video endoscopy system. The pediatric procedural facilities are augmented by a pediatric sedation recovery unit staffed with dedicated nursing personnel. The pediatric GI service also has access to a large adult endoscopy unit including fluoroscopic capability and a fully staffed recovery area. A complete GI motility and manometry unit is available as well as a computerized ambulatory esophageal pH monitoring system.


Both clinical and basic sciences are available.  Opportunities for clinical research are provided through the outpatient clinics and inpatient services at WRNMMC, the Joint Pathology Center (formerly known as AFIP: the Armed Forces Institute of Pathology), the WRAIR, and the University of Maryland.  Fellows performing clinical research will also have the opportunity to complete requirements for the MPH degree at USUHS.

Recent and ongoing research projects and areas of interest of the Pediatric Gastroenterology faculty and fellows currently include:

Eosinophilic esophagitis in children
Mucosal transport regulation in inflammatory bowel disease
Vaccine development for enteric E coli infections
Adherence and virulence factors in Helicobacter pylori infections in children
Clinical aspects of pediatric inflammatory bowel disease

The basic science laboratories include 2000 square feet of space in the Uniformed Services University of the Health Sciences.  The laboratories are well equipped for animal studies, general biochemistry, cell culture, and molecular biology.  Extractions of RNA and DNA, Northern, Western and Southern blotting and polymerase chain reaction analysis are performed.  Gene synthesizers, automated nucleic acid sequencers, and protein sequencing are also available.  Research Administration provides research review services, computerized data analysis, statistical support, and publication pre-review and approval.
