Summary
Brief summary (as posted)
Endomicroscopy (EM) can improve the diagnosis Barrett's esophagus (BE) and some early esophageal cancers (Intra Epithelial Neoplasia (IEN)). EM provides optical biopsies comparable to standard histology. Specifically, EM allows targeted biopsy rather than random mucosal biopsy during routine endoscopic surveillance of BE or evaluation EIN, which will improve the diagnostic yield of mucosal samples for BE IEN. Furthermore, when combined with high resolution endoscopy, EM may improve the overall in vivo detection of IEN in lesions as well as flat mucosa. EM will provide accurate place and size of IEN which will impact the physician's decision to biopsy or perform endoscopic mucosal resection (EMR). This could potentially minimize the number of unnecessary biopsies and as well as enable the physician to perform EMR at the time of the initial examination, rather than delaying endoscopic treatment after the pathology is available. This study is important because it will validate single center studies supporting the routine use of EM for screening and surveillance of BE.

- description
- Compare the diagnostic yield (defined as the proportion of mucosal biopsy samples with neoplasia) of HRE plus EM with directed biopsy (HRE-EM-DB) over HRE with directed biopsy of all mucosal lesions followed by random biopsy (HRE-DB-RB) to diagnose BE in flat mucosa and mucosal lesions The mean diagnostic yield for IEN will be calculated (number of mucosal biopsies and EMR specimens with High Grade Dysplasia (HGD) or Carcinoma (CA) divided by total number of mucosal biopsies obtained) by group and compared, using a chi square or Fisher's exact test for independent groups, depending on the distribution of the data.
