Endoscopy Specialist

What is an endoscopy?

An endoscopy — also called an upper endoscopy or esophagogastroduodenoscopy (EGD) — is a diagnostic procedure Dr. McNamara uses to visually examine the upper portion of your gastrointestinal system. 

During the procedure, he uses an endoscope, which is a long tube with a camera and light attached to the end, to closely evaluate the tissue that lines your esophagus, stomach, and the upper portion of your small intestines, which is called the duodenum. 

Why would I need an endoscopy?

Dr. McNamara values patient education and provides detailed information for why he thinks you need an endoscopy. He may recommend the diagnostic procedure to determine the underlying cause of your gastrointestinal symptoms, such as:

• Abdominal pain
• Difficulty swallowing
• Nausea or vomiting
• Acid reflux

You may also benefit from an endoscopy if further testing is needed to explain abnormalities discovered during an X-ray or ultrasound. Dr. McNamara may also recommend an endoscopy to diagnose or rule out inflammation, ulcers, or tumors in your upper gastrointestinal system. 

How do I prepare for my endoscopy?

Dr. McNamara provides specific guidelines on how to prepare for your endoscopy. To get the best results from the diagnostic procedure, your stomach needs to be completely empty and Dr. McNamara may request that you stop eating and drinking approximately 6-8 hours prior to your test. 

Though you should be able to continue to take most of your medications, some prescriptions or supplements may interfere with the results of your endoscopy and Dr. McNamara may suggest modifying your medication schedule, if needed. 

What can I expect during my endoscopy?

To ease discomfort and anxiety, Dr. McNamara may first spray a numbing agent on your throat and provide a sedative before starting your endoscopy.

During your endoscopy, you lie on your side and Dr. McNamara inserts the endoscope in your mouth and slowly advances it to your esophagus, stomach, and duodenum. 

If tissue abnormalities are found, Dr. McNamara performs a biopsy and sends the tissue sample out for testing.

After your endoscopy, you’re sent to a recovery area for monitoring and Dr. McNamara shares the results of your endoscopy. You’re then sent home once the effects of the sedative wear off. 

Dr. McNamara advises you to arrange for someone to drive you home after you endoscopy and that you limit your activities for the rest of the day.
