Gastroenterology Fellowship

Overview

We appreciate your interest in the Gastroenterology and Hepatology fellowship training program at Cleveland Clinic in Florida. Our department consists of 18 gastroenterologists, five transplant hepatologists, and ten fellows. In late 2023 our training program obtained approval for expansion to 12 fellows and will continue to expand over the next two years to reach a full complement by next year. The goal of our training program is to provide our fellows with a learning environment that will allow them to develop into competent gastroenterologists. Our center is uniquely poised to develop skills that the trainee can subsequently transfer into either a private practice setting or an academic setting.

The endoscopy suite consists of eight procedure rooms where the majority of inpatient and outpatient endoscopic procedures are performed. In the endoscopy suite, the fellow gradually becomes comfortable and experienced with diagnostic and therapeutic endoscopy and colonoscopy. Each fellow is expected to perform about 900 colonoscopies and 700 upper endoscopies throughout their training. In addition, fellows are introduced to and gain experience in advanced endoscopic procedures such as ERCP, EUS, EMR, double balloon enteroscopy, and RFA.

After acquiring expertise in a wide variety of gastrointestinal and liver diseases during the second half of their training fellows may elect to focus on various sub-specialties within gastroenterology and work with a mentor in inflammatory bowel disease, inherited cancer syndromes, motility, hepato-biliary, advanced endoscopic procedures and nutrition.

We invite you to explore the website to learn more about our GI fellowship program.

The Program

Curriculum & Schedule

The schedule is divided into thirteen 4-week blocks. The schedule is designed to provide first year fellows maximum time and experience in the inpatient setting as well as in endoscopy so they become comfortable with the foundations of GI. First year fellows do an average of four inpatient blocks and five endoscopy blocks. As training advances, the fellow is allowed to tailor their schedule while taking into account their inpatient responsibilities. Second year fellows do two inpatient blocks, and third year fellows are responsible for one inpatient block. During the second and third year, fellows are provided ample opportunity to experience “real world” gastroenterology with more time spent in outpatient/specialty clinics and endoscopy.

Fellows are responsible for a weekly half-day continuity clinic. During their three years of training, fellows will build a panel of patients through new referrals, hospital follows ups, and inherited patients from previous fellows’ clinics. Fellows will precept all continuity clinic patients with Dr. Castro, Dr. Pimentel, Dr. Rahman, and Dr. Gonzalez. Fellows are also expected to perform procedures on their patients when necessary.

Educational Conferences

The GI training program provides a robust, multi-disciplinary, academic environment.

State of the Art: An attending is responsible for presenting a topic of their clinical/research interest to the department. The attendings provide a critical review of the literature and analysis of the latest in evidence-based gastroenterology.

Management Conference: The fellow is selected to provide a case-based presentation of both common and uncommon GI illnesses. This is a dynamic and interactive conference where the fellow provides the latest updates on the pathophysiology, diagnosis, and management of a topic of their choosing.

Journal Club: A monthly conference that is mentored by a different attending each month. The attending is responsible for choosing four articles that fall within their area of clinical/research interest. Four fellows will each present a brief review and analysis of the chosen article which is followed by questions and discussion.

Board Review: Board review is conducted twice a month. It’s an interactive session amongst faculty and fellows. Questions, answers, and discussions are drawn from a variety of resources including DDSEP, ACG and Steinberg’s Review.

IBD Conference: A monthly multi-disciplinary conference including GI, colorectal surgery, pathology, and radiology. Unique and challenging cases are presented, and this is followed by a group discussion on issues pertaining to each case.

Program Director Choice: The PD selects a talk or topic and involves the fellows in a discussion. This could relate to recently published guidelines, controversial topics or areas that are not often discussed.

Basic Sciences: A monthly, fellow driven conference where a chapter from Sleissenger and Fordtram’s textbook is reviewed.

Radiology Conference: A monthly conference conducted by a staff abdominal/body radiologist. At the beginning of the academic year, the conferences highlight the principles of GI imaging such as CT enterography and MRCP. As the year progresses, conferences focus on the analysis and interpretation of radiographic imaging in a case-based format.

Pathology conference: Cases and their associated pathology are reviewed with the staff GI pathologist.

Research/QI conference: During this monthly conference, the fellows and attendings discuss research ideas and proposals. This forum also allows for fellows to provide updates on ongoing research in addition to updates on their quality improvement projects. Prior to an abstract presentation at conferences, fellows have the opportunity to rehearse their presentations and receive feedback and critique from their faculty and colleagues.

Rotations

Gastroenterology Consult Service: The fellow is taught how to manage the hospitalized patient with GI disease in a cost effective and expedient fashion. The fellow is responsible for all GI consults that are received from the emergency department, wards, and ICUs. Each block is usually four weeks long. The fellow is supervised and mentored by an attending who is responsible for the GI service. The fellow in this service will perform all inpatient procedures during regular hours. The fellow is exposed to a wide breath of GI pathology. The average census for the inpatient service is about 15 patients and there are 2 fellows in the service.

Hepatology Inpatient and Consult Service: The overall educational goal of this service is for the fellow to learn how to manage the hospitalized patient with liver disease effectively. The fellow is responsible for those patients with complications of chronic liver disease, awaiting liver transplant, and undergoing transplant evaluation. In addition, the fellow is responsible for consultative services for patients with liver disease. The fellow will participate in multi-disciplinary transplant rounds as well as the transplant selection committee, chemical dependency committee, and weekly liver tumor board.

Endoscopy: Under the direct supervision of an attending, fellows are introduced to the basic principles of endoscopy at the very beginning of their training. During their endoscopy rotation, the fellow will become proficient in diagnostic and therapeutic endoscopy and colonoscopy. As their training advances, fellows can participate and gain experience in advanced endoscopic procedures such as ERCP, EUS, EMR, and POEM. Even though fellows will gain adequate experience in advanced endoscopy, the goal of the three-year fellowship is not to obtain credentialing in advanced endoscopy as that is obtained after successful completion of a fourth year, advanced endoscopy fellowship.

Outpatient: During the outpatient rotation, the fellow is assigned to one attending and exposed to a variety of GI diseases. At the beginning of their training, the fellow is encouraged to build a foundation of general gastroenterology, however as their training progresses, fellows can tailor their outpatient experience to suit their clinical interests. Fellows can focus on hepatology, motility, nutrition, inflammatory bowel disease, hepatobiliary, or hereditary cancer syndromes.

Manometry and Capsule Endoscopy: During their training, the fellow will learn the methodology and interpretation of esophageal manometry, impedance and pH testing, capsule endoscopy, and breath testing. Fellows also gain experience in evaluating and interpreting capsule endoscopy. The fellow is responsible for the initial interpretation of all capsule endoscopies and their findings are reviewed with the ordering attending. Manometry and capsule endoscopy are incorporated into the outpatient rotation.
