Pediatric Surgery Residency & Fellowship Program

The University of Oklahoma offers a two-year ACGME-accredited clinical training program, accepting one fellow each year. Fellows in our pediatric surgery program can expect a challenging yet rewarding educational experience. Our graduates complete training with an average of 1,800 cases during fellowship. Board passage rates for our graduating fellows is 100 percent.

Our facility is a regional center for comprehensive, specialized pediatric services and the only fully dedicated, free-standing pediatric hospital in the state, including the only Level Four NICU in the state. More than 2,500 pediatric surgical operations are performed each year by our five full-time pediatric surgeons, and hospital admissions average more than 14,000 per year.

The teaching program emphasizes responsibility, self-directed learning and exposure to a broad spectrum of clinical material. The fellows round twice daily and supervise three general surgery residents, two nurse practitioners, and two medical students assigned to pediatric surgery. Faculty members are available for constant interaction and feedback. Please watch our program video here.

Supervision & Continuity of Care

Year one: Pediatric surgery training involves a closely supervised two-year period of education, gradually giving trainees more responsibility and independence. The initial six months of training will expose the resident to clinical care of all common and tertiary pediatric surgery problems. The second six months is focused on directing the trainee to become more independent in his/her patient care management; building a broad base of knowledge in both pediatric physiology and pathobiology and incorporating a collaborative clinical research project with the faculty. Constant communication between the first-year trainee, the attendings and the senior fellow is expected.

Year two: During the second year of training, the trainee is expected to perform in a more independent fashion, making important decisions regarding preoperative, intraoperative and postoperative patient management. The fellow is given additional teaching and administrative responsibilities, as well as additional independent operating room experience as his/her technical skills are developed through one-on-one teaching. Progression of responsibility toward independent performance, especially during the last six months of clinical training, is strongly promoted by faculty. Pediatric surgery attendings continually monitor and provide appropriate feedback to the pediatric surgery fellow throughout his/her clinical training both in and out of the operating room.

Continuity of Care

The pediatric surgery fellows are responsible for the direct management of all patients in pediatric surgery. The fellows are assigned to coordinate all patient care activities, including inpatient care, operating room case assignments, emergency room consultation, daily rounds, inpatient consultations and attendance at conferences. The caseload provides a balanced mix of ambulatory surgical, neonatal and complex operative cases, giving trainees a well-rounded learning experience.

Each morning and afternoon, the fellows lead rounds with surgical residents and medical students, followed by service planning for the day and a review of patient status with the on-call attending surgeon. Operating room responsibilities for the day are assigned by the fellows. All patient management plans are reviewed with the patient’s attending surgeon prior to implementation, and all inpatient consults are discussed with the on-call attending. The Pediatric Surgery Service is responsible for all ECMO management, which is coordinated by the fellows and the surgical faculty.

The Pediatric Surgery Service has outpatient office hours each weekday, during which the fellows may evaluate patients and discuss plans with the attending surgeons. This experience allows the resident to follow long-term patients, gaining an important perspective on their growth, development and care managements. As trainees progress during fellowship, the attendings encourage more independent management of patients.



Department of Pediatric Surgery Faculty

Department of Pediatric Surgery Conferences

Fellows are encouraged to initiate self-learning through a structured didactic teaching schedule that includes weekly presentations on topics related to recent pediatric cases. A wide variety of didactic lectures and surgical teaching conferences, based on The Surgical Council on Resident Education (SCORE) curriculum, are part of our training program. The fellows are responsible for the organization and assignment of presentations by faculty, general surgery residents and medical students for the weekly pediatric surgery conferences.

Clinical Sciences/SCORE Conference (Monday mornings)

• Attended by faculty, fellows, residents, students, nurses and nurse practitioners

This weekly conference is designed to discuss the areas outlined in SCORE curriculum, which is developed around the six competencies required of a graduating resident: patient care and procedural skills, medical knowledge, professionalism, communication, practice-based learning, and systems-based practice. This conference also helps prepare fellows for the Pediatric Surgery Certifying exam, as the faculty expand on challenging topics.

Morbidity & Mortality (M&M) Conference (Friday mornings)

 Attended by faculty, fellows, nurses and nurse practitioners

M&M is a bi-weekly conference during which surgical statistics are presented and inpatient and outpatient surgical management is reviewed.

Journal Club

• Attended by faculty, fellows and residents

Faculty and residents participate in lively discussions each month regarding current and interesting additions to professional literature from the core surgical journals.

Radiology Conference

 Attended by faculty, fellows, residents, students, nurses and nurse practitioners

Each month both interesting cases recently performed and upcoming cases are reviewed with attending radiologists.

Multidisciplinary Tumor Conference

 Attended by faculty, fellows and residents

This weekly conference provides the fellows an opportunity to discuss patients in a multidisciplinary setting, review imaging and pathology, and formulate treatment plans.

GI/Surgery Conference

• Attended by faculty, fellows and residents

This conference occurs monthly and is designed to allow discussion of important topics that involve the coordination of care between the GI and surgical services. The GI fellow and junior pediatric surgery fellow each present on a given topic.

Comments from Past Graduates:

Keith Webb, MD: “Oklahoma is a phenomenal place to train. The atmosphere is collegial. You assume real responsibility for the service immediately. There is ample opportunity to teach residents and students. This is a high-volume center, and you will operate on half that volume. (The downside of having two fellows.) You will quickly gain operative autonomy. This is THE research center for the state, a leader in the region, and involved in cooperations on a national level. I genuinely enjoyed working with each of the attendings. If I were back in the position of applying for fellowship with what I know now, I would still want to train at OU Children's Hospital.”


Jack Schneider, MD: "The OU pediatric surgery fellowship provides exceptional training. The case volume, breadth and complexity is outstanding and will provide graduates with the knowledge, experience and technical expertise to be comfortable managing basic and index level procedures immediately as they start practice. Didactic and multidisciplinary meetings allow the fellow to assimilate the requisite academic information to allow her/him to be confident when taking the written and oral board exams. Administrative duties are not onerous; however, those required allow the trainee to understand team and program management. As a senior fellow, you are the leader of the service, and have impeccable faculty support in doing so. Finally, there is a collegial atmosphere where you are respected and valued both as a surgeon and a person. I could not be happier to be part of the OU Pediatric Surgery Family and would choose this fellowship again in a heartbeat."
