High Resolution Microendoscopy for the Detection of Esophageal Squamous Cell Neoplasia

Summary

The overall objective of this multicenter trial is to determine whether the use of a low-cost, high-resolution microendoscope during diagnostic upper endoscopy can improve the efficiency and accuracy of endoscopic screening for esophageal squamous cell neoplasia. This is a multicenter clinical trial of a novel technology, a miniaturized, lower cost (\< $3, 500) microscope device which can be used during upper endoscopy to image the gastrointestinal epithelium. This high-resolution microendoscope (HRME) was developed by our collaborators at RICE University and provides \>1000X magnified images of the esophageal mucosa.
