Diagnosing Barrett's Esophagus: What to Expect During Your Endoscopy
Published: Sep 18, 2023
An upper endoscopy is the gold standard for diagnosing Barrett's esophagus. This article will walk you through what to expect during this important diagnostic procedure.
What is an Upper Endoscopy?
An upper endoscopy, also called an EGD, is a procedure that allows doctors to examine the lining of your upper digestive system. A thin, flexible tube with a camera on the end is gently inserted through your mouth and into your esophagus. It's like sending a tiny explorer into your body to gather information. This procedure is usually quick, lasting about 10-15 minutes, and is performed while you're sedated for comfort.
The Biopsy Process
During the endoscopy, if your doctor suspects Barrett's esophagus, they'll take small tissue samples called biopsies. This is crucial for confirming the diagnosis. The doctor will take at least four biopsies for every 2 cm of suspected Barrett's tissue. It might sound like a lot, but these samples are tiny - about the size of a pinhead. Think of it as collecting puzzle pieces to complete the diagnostic picture.
What the Doctor Looks For
Your doctor will be on the lookout for a salmon-colored lining in your lower esophagus, which is characteristic of Barrett's esophagus. They'll also measure how far this unusual lining extends up your esophagus. This measurement helps classify Barrett's as short-segment (less than 3 cm) or long-segment (3 cm or more). It's like mapping out the affected territory in your esophagus.
