Biography

 

Tarek Sawas, M.D., is an Assistant Professor in the Department of Internal Medicine at UT Southwestern Medical Center, and a member of its Division of Digestive and Liver Diseases. He specializes in pancreaticobiliary diseases, bariatric endoscopy, esophageal cancer, and endoscopic resection.

I am driven by UT Southwestern's collaborative, multidisciplinary approach that focuses on assuring the best care and putting patients' interests above all.

Dr. Sawas earned his medical degree at Damascus University Faculty of Medicine and completed a residency in internal medicine at Georgetown University Washington Hospital Center. He then performed fellowships in gastroenterology and hepatology and in advanced endoscopy, both at the Mayo Clinic. He also holds a Master of Public Health in epidemiology from Harvard University.

Certified by the American Board of Internal Medicine in gastroenterology, Dr. Sawas joined the UT Southwestern faculty in 2020.

Dr. Sawas’ clinical practice includes endoscopic retrograde cholangiopancreatography (ERCP); endoscopic ultrasound (EUS); and endoscopy to treat weight gain, such as endoscopic sleeve gastroplasty (ESG), transoral outlet reduction (TORe) in patients with weight regain after weight loss surgery (Roux-en-Y gastric bypass), and endoscopic mucosal resection to treat early cancer in a minimally invasive way.

As a clinical researcher, he has received the American Gastroenterology Association (AGA) early career investigator award, and the 2019 Summerskill’s award from the Mayo Clinic. He has published extensively in prestigious journals on esophageal cancer, bile duct cancer and bariatric endoscopy. He also serves as a reviewer to multiple journals.

Dr. Sawas is an active member of several professional organizations, including the American College of Gastroenterology, the American Society for Gastrointestinal Endoscopy, and the American Gastroenterological Association.

Personal Note

Dr. Sawas’ interests outside of medicine include spending time with his family, playing tennis, and hiking.
