Upper Endoscopy at Medical City Frisco
Upper endoscopy or esophagogastroduodenoscopy (EGD) is a diagnostic procedure that allows the physician to diagnose and treat problems in the upper gastrointestinal (UGI) tract.
Upper endoscopy procedure at Medical City Frisco
For the procedure you will swallow a thin, flexible, lighted tube called an endoscope. Right before the procedure the physician will spray your throat with a numbing agent that may help prevent gagging. You may also receive pain medicine and a sedative to help you relax during the exam. The endoscope transmits an image of the inside of the esophagus, stomach, and duodenum, so the physician can carefully examine the lining of these organs. The scope also blows air into the stomach; this expands the folds of tissue and makes it easier for the physician to examine the stomach.
The procedure takes 20 to 30 minutes. Because you will be sedated, you will need to rest at the endoscopy facility for 1 to 2 hours until the medication wears off.
