NCT01032044

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Number of Barrett's Esophagus (BE) Participants With a Composite Outcome of "Optimally Treated"

    Number of Barrett's Esophagus (BE) Participants with a Composite Outcome of "Optimally Treated", 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.

    3 month follow-up endoscopic procedure

Study Arms (2)

Standard endoscopic evaluation

ACTIVE COMPARATOR

Standard high-definition white light endoscopy guided evaluation

Device: Standard endoscopic evaluation

pCLE-guided evaluation

EXPERIMENTAL

Endoscopic evaluation of BE guided by probe-based Confocal Laser Endomicroscopy (pCLE guided evaluation)

Device: pCLE guided evaluation

Interventions

Treatment modalities can include endoscopic mucosal resection, radio-frequency ablation or photodynamic therapy

Standard endoscopic evaluation

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.

pCLE-guided evaluation

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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.
