Clinical Facilities

LAC+USC Medical Center

Founded in 1878, Los Angeles County LAC+USC Healthcare Network (LAC+USC) is the nation’s largest academic institution. It is one of the largest acute care hospitals in America and has been the primary facility of the University of Southern California School of Medicine since 1885. Originally established as a 100-bed hospital with 47 patients, it now is licensed for 1,395 beds and budgeted to staff 745 beds. Fellows rotate here on inpatient GI and Liver consultation services, endoscopy, and outpatient GI, Liver, and Hepatitis clinics.

Keck Medical Center of USC

Keck Hospital of USC is a private 401-bed acute care hospital staffed by the faculty of the Keck of School of Medicine of USC. Gastroenterology fellows rotate here to the inpatient GI consultation service and an inpatient hepatology and liver transplant service. Keck Hospital of USC and USC Norris Cancer Hospitals are major tertiary referral centers and are consistently recognized as among the top hospitals in the nation.


Clinical Training

All Gastroenterology Fellows are co-sponsored by the University of Southern California’s Keck School of Medicine and the Los Angeles County+USC Medical Center. Fellows are selected to a three-year general gastroenterology program; Fellows participate in inpatient GI and liver consultation services at three major USC affiliated hospitals that affords exposure to a broad range of clinical experiences.

In general, clinical rotations are in month-long blocks. First year fellows typically spend 4 months on inpatient GI consult services, 4 months on endoscopy, 1 month on the Liver consult service, 1 month on the Hepatology/Transplant service at Keck Hospital at USC, along with 1 month of research time. Second and third year fellows participate in similar rotations with increasing degrees of clinical responsibility.

Outpatient care experiences are provided by weekly GI and Liver clinics at the Edward Roybal Community Healthcare Center and the Hepatitis Clinic at LAC+USC. Through these experiences, fellows are exposed to a continuity of care for patients with a wide variety of gastrointestinal and liver diseases.

Endoscopic Training:

The USC GI Fellowship Program offers superb opportunities for endoscopic training. Fellows perform endoscopic procedures at LAC, Norris Cancer Hospital, and USC University Hospital. All endoscopy units are well equipped with state-of-the-art video/computerized endoscopes. Diagnostic and therapeutic endoscope procedures are performed throughout the three years of fellowship training. Endoscopic training in biliary therapeutic technique and other special procedures are offered in the 3rd year of training.

Research Training

Fellows have the opportunity during their fellowship to participate in clinical or basic science research activities. Fellows may participate in ongoing faculty research projects or their own research interests. They will be able to work closely with a faculty preceptor who will provide support, guidance and instruction regarding clinical and basic science research techniques, as well as academic career development. Scientific background, study design, laboratory methods, and biostatistics will be emphasized. Fellows will have the opportunity to present their work during GI/Liver division research seminars and at national meetings (AGA and AASLD).

Liver Transplant Program:

The USC Liver Transplant Program was started in December 1995 and is based at the Keck Hospital of USC. Fellows rotating at the Keck Hospital have the opportunity to participate in the care of patients with advanced liver disease.

The program is now accepting applications for 2020-2021 and 2021-2022.
