NvisionVLE - Imaging System with Real-time Targeting - Brochure

The most widely used imaging modality for standard endoscopic examination, white light endoscopy (WLE). is limited to evaluation of the surface of the esophageal tissue. It is becoming increasingly recognized that esophageal abnormalities may be present below the surface where they can`t be visualized with WLE. Random biopsy is the current standard of care for diagnosing esophageal disease such as Barrett`s esophagus, squamous cell carcinoma, and adenocarcinoma. However, random biopsies assess less than 3% of the esophageal surface.1 leaving more than 9796 of the tissue un-sampled. Further, even when the tissue is L targeted appropriately, biopsies have " been shown to reach the lamina propria only 3796 of the time.2 This often is not at sufficient depth to reach the area of concern.
