NCT00795184

Brief Summary

This study will collect data from patients routinely undergoing a endoscopic surveillance and Cellvizio endomicroscopy procedure due to confirmed Barrett's esophagus. The objective is to determine if endomicroscopy images collected using the marketed Cellvizio device may help endoscopists more accurately diagnose, in conjunction with traditional tissue sampling techniques, whether a suspected lesion is malignant or benign.

Outcome Measures

Primary Outcomes (1)

  • Comparative Histopathology-confirmed Measures of Per Lesion Sensitivity and Per Lesion Specificity, by Using pCLE Associated With WLE, or WLE Alone, for the Detection of High Grade Dysplasia and Early Carcinoma in Barrett's Esophagus.

    Comparative Histopathology-confirmed Measures of Per Lesion Sensitivity and Per Lesion Specificity, by Using Probe-based Confocal Laser Endomicroscopy (pCLE) Associated With White Light Endoscopy (WLE), or WLE Alone, for the Detection of High Grade Dysplasia and Early Carcinoma in Barrett's Esophagus.

    Centralized histopathology confirmation within 4-6 weeks

Study Arms (2)

Imaging Procedures HDWLE first NBI second and pCLE

OTHER

All patients undergo both endoscopic imaging procedures and then the endomicroscopy procedure; the endoscopic imaging procedures being performed back to back by two endoscopists, blinded to each other.

Interventions

Imaging procedures (pCLE) and (NBI) - All patients undergo both procedures back to back by two endoscopists, blinded to each other, in randomized order. Procedure 1: Standard endoscopic procedure The patient receives white light endoscopy (WLE) examination. All visible lesions are noted and photographed. No biopsy is taken until both procedures are complete. Procedure 2: NBI endoscopic procedure The patient receives a NBI endoscopy examination. All visible and NBI abnormal lesions are noted and photographed. After both procedures are complete and all sites are unblinded to both endoscopists. pCLE with Cellvizio and physical biopsies are performed at all sites plus 4 quadrant sites.
