What is an Upper Endoscopy?
Also know as an EGD gastroscopy, or esophagogastroduodenoscopy. During an upper endoscopy your gastroenterologist will use a small, bendable lighted tube, that he/she inserts through the mouth, in order to closely examine the lining of your esophagus, stomach, and the top portion of your intestines, known as the duodendum.
Who Needs an EGD?
First of all, a doctor will recommend an EGD procedure for patients experiencing symptoms such as persistent stomach or abdominal pain, vomiting, trouble swallowing, and heartburn. They will also recommend an EGD for those who have a family history of esophageal cancer. It can find and evaluate bleeding, inflammation, ulcers, and tumors of the esophagus, stomach, and duodenum. An EGD is useful for detecting cancer, allowing your gastroenterologist to distinguish between cancerous and non-cancerous conditions in the upper GI tract more accurately than an x-ray.
What is the Prep?
In order to prepare for an upper endoscopy, your gastroenterologist will give specific prep instructions. He/she will usually request that you refrain from eating or drinking anything for approximately 8 hours before the exam. Your stomach will need to be completely empty. Your gastroenterologist will give you very specific instructions regarding when to begin fasting based on when your procedure is scheduled.
