What is Upper Endoscopy?
Upper Endoscopy (also known as gastroscopy, EGD, or esophagogastroduodenoscopy) is a procedure that enables your surgeon to examine the lining of the esophagus (swallowing tube), stomach and duodenum (first portion of the small intestine). A bendable, lighted tube about the thickness of your little finger is placed through your mouth and into the stomach and duodenum.
About Upper Endoscopy (EGD)
Why is an Upper Endoscopy Performed?
Upper endoscopy is performed to evaluate symptoms of persistent upper abdominal pain, nausea, vomiting, difficulty swallowing or heartburn. It is an excellent method for finding the cause of bleeding from the upper gastrointestinal tract. It can be used to evaluate the esophagus or stomach after major surgery. It is more accurate than X-rays for detecting inflammation, ulcers or tumors of the esophagus, stomach and duodenum. Upper endoscopy can detect early cancer and can distinguish between cancerous and noncancerous conditions by performing biopsies of suspicious areas. Biopsies are taken by using a specialized instrument to sample tissue. These samples are then sent to the laboratory to be analyzed. A biopsy is taken for many reasons and does not mean that cancer is suspected.
A variety of instruments can be passed through the endoscope that allows the surgeon to treat many abnormalities with little or no discomfort. Your surgeon can stretch narrowed areas, remove polyps, remove swallowed objects, or treat upper gastrointestinal bleeding. Safe and effective control of bleeding has reduced the need for transfusions and surgery in many patients.
What to expect before the procedure
What Preparation is Required?
The stomach should be completely empty. You should have nothing to eat or drink for approximately 8 hours before the examination. Your surgeon will be more specific about the time to begin fasting depending on the time of day that your test is scheduled.
Medication may need to be adjusted or avoided. It is best to inform your surgeon of ALL your current medications as well as allergies to medications a few days prior to the examination. Most medications can be continued as usual. Medication use such as aspirin, Vitamin E, nonsteroidal anti-inflammatories, blood thinners and insulin should be discussed with your surgeon prior to the examination. It is essential that you alert your surgeon if you require antibiotics prior to undergoing dental procedures, since you may also require antibiotics prior to gastroscopy.
Also, if you have any major diseases, such as heart or lung disease that may require special attention during the procedure, discuss this with your surgeon.
You will most likely be sedated during the procedure and an arrangement to have someone drive you home afterward is imperative. Sedatives will affect your judgment and reflexes for the rest of the day. You should not drive or operate machinery until the next day.
