Barrett's esophagus other imaging findings

Introduction

Overview

Overview

Unsedated esophagoscopy and capsule esophagoscopy may be helpful in the diagnosis of Barrett’s esophagus.

Other Imaging Findings

Other Imaging Findings

Unsedated Esophagoscopy

  • Aaerosolized 14% benzocaine is instilled into the oropharynx for 3 seconds.
  • 4.9 mm diameter flexible endoscope with a 2 mm working channel is passed transnasally through the nasal turbinate into the oropharynx, hypopharynx, esophagus, and stomach.

Capsule Esophagoscopy

  • The esophageal capsule is swallowed and allows for capture of 14 images per second by using two optical domes.[3][4]
  • Patient takes sips of water every 30 seconds during the 3 minutes with the patient lying in the right lateral supine position which provides better visualization of the z-line.
