Andrei C. Gasic, MD, is a board-certified gastroenterologist at UT Health East Texas Physicians Tyler who offers expertise in many GI procedures. Dr. Gasic is one of the few area specialists providing pediatric GI services (patient ages 6 to 18), and he speaks fluent Spanish. “I went into medicine because I was interested in science, and initially in research, but I gravitated to patient care. The fact that I am bilingual helps me serve the Hispanic community.”

In addition to standard GI procedures, like upper endoscopy and colonoscopy, Dr. Gasic offers patients the ERCP/SpyGlass system, helping doctors diagnose and treat cancers of the bile duct and pancreas; HALO ablation technology, to remove Barrett’s tissue from the esophagus; minimally invasive hemorrhodial procedures; assessment of reflux disease; evaluation of GI motility disorders and treatment of liver diseases.

Experienced in physician education and research, Dr. Gasic has established ties with the regional medical community. “I’ve always liked UT Health Tyler and the system’s highly regarded physicians.”

In Philadelphia, Dr. Gasic earned his bachelor’s degree in biology from The University of Pennsylvania and his doctor of medicine from the Medical College of Pennsylvania.

I have been using Dr Gasic for about 9-11 yrs now. He always been great to me and always concerned about what’s going on with me. He is very kind and attentive. I don’t get why someone would post negatively about him because he’s never come across as anything but professional & caring. I highly recommend him to all that need testing done.

Ive used Dr. Gasic for well over 20 years now. He has always been kind and helpful and thorough. He caught my precancerous colon and also a tumor that caused the need for resection.

Dr. Gasic is very patient and caring. He took time to listen to me on my first visit and I didn’t feel rushed. Dr. Gasic and the entire staff in the office are always friendly and caring.

Oh my gosh, Dr. Gasic helped save my life. Had to have emergency surgery for the removal of my gall bladder. The pain was unbearable and I just thank him so very much for his experience, kindness and professionalism!
