Professional Statement

Omar Barakat, M.D. is a general surgeon with more than twenty years of experience in diagnosing and treating benign and malignant diseases of the liver, bile duct, gallbladder, and pancreas. After completing his general surgery residency in the Medical College of Pennsylvania, Episcopal Hospital in Philadelphia in 1992, he pursued a liver transplantation fellowship at The University of Texas Health Science Center in Houston.

Dr. Barakat continued his practice in liver and pancreatic surgery in England, where in 1998 he joined the Freeman Hospital in Newcastle Upon-Tyne, UK. For the next five years he gained extensive experience in treating complex and rare tumors of the liver, bile duct, and pancreas.

Dr. Barakat returned to Houston in 2003 and has been applying his special expertise to treat malignant hepatobiliary and pancreatic diseases, gastrointestinal stromal tumors (GIST), and neuroendocrine tumors (NET). Currently, he serves as the medical director of the newly established neuroendocrine program at Baylor St. Luke’s Medical Center. The program includes a multidisciplinary group of gastroenterologists, medical oncologists, radiologists, pathologists, and radiation oncologists.

Dr. Barakat has developed new surgical techniques to minimize the complication rate and blood loss following pancreatic and liver surgeries. He utilizes image-guided therapies, such as radiofrequency ablation, microwave ablation, irreversible electroporation (NanoKnife system), trans-arterial chemotherapy, and selective internal radiotherapy (SIRT) with Yttrium-90 microspheres, to treat liver tumors while minimizing trauma to the patients.

Dr. Barakat's clinical and basic science research interests also include the study of neuroendocrine tumors and the development of off-the-shelf bio-artificial liver organs that can be suitable for liver transplantation in patients with end-stage liver disease.
