Gastroenterologist: A Gastroenterologist can perform an upper endoscopy to view your esophagus, stomach and duodenum - EGD procedure. Through this method he/she will view through a scope and biopsy areas necessary such as polyps, ulcers, or any suspicious lesions. This tissue will be submitted for for evaluation by a Pathologist. Your biopsy results will be available in one week approximately.
