What is EGD?

An EGD is a test in which Dr. Kang views the lining of your esophagus, stomach, and the top part of your small intestine through an endoscope to make a diagnosis or deliver treatment if you’re having gastrointestinal issues.

When do I need an EGD?

If you’re having any of the following issues, Dr. Kang may recommend an EGD:

  • Throat pain
  • Difficulty swallowing
  • Heartburn
  • Upper abdominal pain
  • Vomiting blood
  • Frequent regurgitation
  • Black or tarry stools
  • Feeling full too fast
  • Unintended weight loss

In some cases, like in the case of a bleeding peptic ulcer in peptic ulcer disease, Dr. Kang can also perform treatment during an EGD. Such treatment can include:

  • Injection therapy, usually diluted adrenaline
  • Heat therapy to coagulate blood
  • Clips or bands to tie the bleeding vessels off

Dr. Kang can also perform other treatments, such as widening a narrowed esophagus, during an EGD when needed.

Dr. Kang might recommend an EGD when you’ve already been diagnosed with a condition like Crohn’s disease, and he needs to monitor changes in your upper gastrointestinal tract. If needed, he can also take a tissue sample for biopsy during your EGD.

How do I prepare for EGD?

Dr. Kang gives you specific prep guidelines. Typical requirements include fasting for up to 12 hours before the EGD, discontinuing aspirin and other blood-thinning medications for at least a few days beforehand, and arranging for a loved one to drive you home following the procedure since you'll still be slightly groggy from sedation.

How does EGD work?

EGD is typically an outpatient procedure that Dr. Kang performs at a surgical center or hospital. You’ll receive a mild sedative and might also get a local anesthetic spray to keep you comfortable before the EGD starts. You lay on your left side, and Dr. Kang threads the endoscope through your mouth and down your throat.

The endoscope, a thin, flexible tube containing a light source and a tiny camera, relays images to a monitor where Dr. Kang views your upper gastrointestinal tract. Dr. Kang monitors your vital signs continuously through the procedure to ensure your safety. Most patients don’t remember the EGD test, and there’s usually no downtime needed.

An EGD can help you get the answers if you’re dealing with throat pain, swallowing difficulties, side effects of peptic ulcer disease, or other gastrointestinal problems. Book your appointment at Gastroenterology Consultants of West Houston, PLLC online or by phone now.
