This study focuses on demonstrating the value of probe-based Confocal Laser Endomicroscopy (pCLE) in guiding endoscopic therapeutic procedures in Barrett's Esophagus (BE).

It is a randomized controlled outcomes study including patients already treated for Barrett's Esophagus lesion(s) and undergoing high definition white light endoscopy follow up procedure, with or without pCLE (2 arms will be considered in this study). The procedures will be carried out per standards of practice with appropriately trained physicians.

Primary Outcome Measures:
  • Composite outcome of "optimally treated" BE patients in each group defined as patients for whom all lesions are ablated when disease is present, or not ablated when disease is absent, or have complete ablation of all disease at the 3 month follow-up. [ Time Frame: 3 month follow-up endoscopic procedure ] [ Designated as safety issue: No ]

Enrollment: 166
Study Start Date: February 2010
Study Completion Date: April 2011
Primary Completion Date: April 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Standard treatment
Standard high-definition white light endoscopy guided treatment
Device: Standard endoscopic treatment of BE
Treatment modalities can include endoscopic mucosal resection, radio-frequency ablation or photodynamic therapy
Experimental: pCLE-guided treatment
Endoscopic treatment of BE guided by probe-based Confocal Laser Endomicroscopy
Device: pCLE guided endoscopic treatment of BE
Treatment modalities include endoscopic mucosal resection, radio-frequency ablation, or photodynamic therapy. probe-based Confocal Laser Endomicroscopy is used to decide on re-treatment or not, and to guide and evaluate the treatment during the same endoscopic procedure.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients with BE with Intestinal Metaplasia, Low Grade-IntraEpithelial Neoplasia/High Grade-IntraEpithelial Neoplasia as the original indication for ablative treatment.
  • Undergoing any type of endoscopic BE ablation treatment
  • <2cm of circumferential BE and <5 total islands of BE on prior to last ablation.
  • Age > 18 years
  • Ability to provide written, informed consent

Exclusion Criteria:

  • Participation in another clinical study
  • Circumferential BE
  • Complete eradication of BE documented by biopsies
  • Inability to obtain biopsies due to anticoagulation, varices, etc.
  • Allergy to fluorescein
  • Pregnancy
