Gastroenterology Fellowship

Applications for the Parkview Medical Center Osteopathic Gastroenterology Fellowship Program are done through ERAS. If you are interested in more information, please contact Megan Caruso, Program Coordinator, 719-584-4980. Please note that Parkview Medical Center's fellowship programs have recently received ACGME accreditation and are now accepting MD applicants. However, Parkview will only be considering J-1 visas with sponsorship from ECFMG on a case by case basis.

General Objectives of the Gastroenterology Fellowship Program

The Fellowship programs seeks to provide candidates with the opportunity to become consultant level subspecialists, qualified to function as independent resources for the communities in which they practice. The Fellowship program provides an intensive clinical exposure, an extensive didactic program, in which the Fellow is expected to actively participate, both as a student and a trainer, and an introduction to clinical research. While opportunities to participate in active research projects are available, this is not a research based fellowship program and candidates anticipating careers as physician-researchers are encouraged to seek training in programs more closely suited to their chosen career paths.

CLINICAL EXPERIENCE Fellows have formal instruction, clinical experience, and demonstrate competence in the evaluation and management of the following disorders:

  • Disease of the esophagus
  • Acid peptic disorders of the gastrointestinal tract
  • Motor disorders of the gastrointestinal tract
  • Irritable bowel syndrome
  • Disorders of nutrient assimilation
  • Inflammatory bowel diseases
  • Vascular disorders of the gastrointestinal tract
  • Gastrointestinal infections, including retroviral, mycotic, and parasitic infections
  • Gastrointestinal diseases with an immune basis
  • Gallstones and cholecystitis
  • Alcoholic liver diseases
  • Cholestatic syndromes
  • Drug-induced hepatic injury
  • Hepatobiliary neoplasms
  • Chronic liver disease
  • Gastrointestinal manifestations of HIV infections
  • Gastrointestinal neoplastic disease
  • Acute and chronic hepatitis
  • Biliary and pancreatic diseases
  • Women’s health issues in digestive diseases
  • Geriatric gastroenterology
  • Gastrointestinal bleeding
  • Cirrhosis and portal hypertension
  • Genetic/inherited disorders
  • Medical management of patients under surgical care for gastrointestinal disorders
  • Management of GI emergencies in the acutely ill patient

Internal Medicine sub specialties have, as their base, excellence in Internal Medicine. The Fellowship Program seeks to build on previously established knowledge and skills. The successful candidate will demonstrate competence in the broad field of Internal Medicine. Excessive exposure to Gastroenterology during an Internal Medicine Residency, thus limiting training in the other aspects of Internal Medicine does not optimally prepare a physician to specialize in these fields. The well-rounded candidate, demonstrating mastery of the primary specialty, will ultimately become a better consultant and physician. During the course of the Fellowship program, the trainee will spend a considerable amount of time on services other than Gastroenterology. These rotations are expected to broaden the knowledge and experience of the Fellow in such areas (i.e. Radiology, pathology, Surgery, Infectious Disease) which impact directly on patients with Gastroesophageal Illness.

The program emphasizes graduated responsibility with the Fellow gradually assuming responsibility under the supervision of both the rotation supervisor and the Program Director. It is expected that the trainee will interact closely with attending physicians and other consultants. The Fellow serves as an educator, mentor and supervisor for junior house-staff. The Fellow is also expected to serve as a resource and aid to the Nursing Staff of the Hospital. The Fellow will be assigned to medical staff committees in a nonvoting status with responsibilities commensurate with level of training and skill. Administrative responsibilities are assigned under the supervision of the Program Director. In order to function effectively in the medical environment, the Fellow must become aware of costs, cost containment efforts, and the medical-legal implications of clinical decisions.

Fellows will gain outpatient experience in the private offices of faculty members, typically once per week for an average of 4 hours.

The Fellow is encouraged to prepare an annual scientific paper upon a subject acceptable to the Program Director. The paper is to be suitable for publication, and, following approval by the Program Director and Director of Medical Education (DME) / Designated Institutional Official (DIO) should be considered for submission for publication to an appropriate peer-review journal. The paper may take the form of an independent research project, a case report and review of the literature or such other form as the Program Director and DME / DIO may approve. If the paper is accepted for presentation at a national conference, the program will pay for the day of the presentation and one travel day associated with the conference. There may a possibility of coordination with the basic science or translational research departments at CSU-Pueblo for research projects as well.

It is anticipated that the Fellow will maintain membership in the American College of Gastroenterology. During the course of the Fellowship program the Fellow is encouraged to attend at least one of the annual meetings of these organizations. The choice of meetings is subject to the approval of the Program Director. The goal is for the Fellow to gain exposure to the professional societies they will interact with for the remainder of their career.

The program will pay for each fellow to sit for the Gastroenterology Board Review Course at the end of their third year. Payment will include the cost of the course, airfare, room and board up to $2,000.00.

The Fellow is expected to gain competence in the clinical and ancillary evaluation of patients presenting with symptoms potentially arising from gastroesophageal illness. Listed below are procedural skills which should be acquired by the trainee during the course of the program. The Program Director, advised by the faculty members, serves as the final arbiter of competence and satisfactory completion of the goals and objectives of the training program.

Technical and other skills

GI Summer Clinical Lecture Faculty review clinical aspects of acute management of common GI diseases. This is an introductory clinical series that goes from July to September each year on Tuesdays at 7am.

Core Curriculum Lecture Series is where fellows learn in depth about basic GI pathophysiology and attain new non-textbook knowledge on focused GI topics in a seminar format through study of literature and input from an assigned expert in the field. Fellows learn how to critically appraise and present recent scientific literature of a focused topic. This follows the GI/Hepatology Summer Clinical Lecture Series and goes from October to June each year.

Ambulatory Clinic

Parkview Gastroenterology operates an ambulatory clinic that will be utilized for Fellowship training with continuity of care.

Parkview Gastroenterology 1600 N. Grand Avenue, Pueblo, CO 81003 Phone: 719-595-7680

The payer mix is 59.2% Medicare, 10% Medicaid, 29.4% HMO/PPO/3rd Party, and 1.5% Self Pay. The approximate annual volume for 2012 was 3,175 patients and the annual number of visits in 2012 was 21,289.
