Upper endoscopy.

Upper endoscopy, also known as an EGD, enables us to examine the lining of the stomach, esophagus or upper intestine using a flexible tube with its own lens and light source. It is used to evaluate symptoms such as upper abdominal pain, nausea, vomiting, difficulty swallowing or unexplained weight loss. Dr. Winston can diagnose inflammation, ulcers and early stage cancer with this procedure.
