An upper endoscopy, often referred to as endoscopy, EGD, or esophago-gastro-duodenoscopy, is a procedure that allows a physician to directly examine the upper part of the gastrointestinal (GI) tract, which includes the oesophagus , the stomach, and the duodenum.
You will be given specific instructions regarding how to prepare for the examination before the procedure. These instructions are designed to maximize your safety during and after the examination and to minimize possible complications.
Your doctor will pass special surgical tools through the endoscope to collect a tissue sample or remove a polyp. Your doctor watches the video monitor to guide the tools.
When your doctor has finished the exam, the endoscope is slowly retracted through your mouth. Endoscopy typically takes five to 20 minutes, depending on your situation.
You'll be taken to a recovery area to sit or lie quietly after your endoscopy. You may stay for an hour or so. This allows your health care team to monitor you as the sedative begins to wear off.
Once you're at home, you may experience some mildly uncomfortable signs and symptoms after endoscopy, such as:
These signs and symptoms will improve with time. If you're concerned or quite uncomfortable, call your doctor.
Take it easy for the rest of the day after your endoscopy. You may feel alert, but your reaction times and judgment are delayed after receiving a sedative.
If your doctor performed the endoscopy to look for an ulcer, you may learn the findings right after your procedure. If a tissue sample (biopsy) was collected, it may take a few days to get results from the testing laboratory. Ask your doctor when you can expect the results of your endoscopy.
After the endoscopy, you will be observed for a period of time, generally less than one hour, while the sedative medication wears off. Some of the medicines commonly used cause some people to temporarily feel tired or have difficulty concentrating. You typically will be instructed not to drive and not to return to work for the balance of the day of the procedure.
The most common discomfort after the examination is a feeling of bloating as a result of the air introduced during the examination. This usually resolves quickly. Some patients also have a mild sore throat. Most patients are able to eat shortly after the examination.
