"Intravenous administration of a microdose (4.5mg, subtherapeutic) of Bevacizumab-IRDye800CW 2 days prior to the fluorescence endoscopy procedure.~\* amendment June 2015: topical administration bevacizumab-800CW (100ug/ml)"

A flexible fiber-bundle is attached with its proximal end to a camera which can detect near infrared fluorescent light. The distal end is inserted into the working channel of a clinical video endoscope to visualize the luminal wall. The fluorescent imaging will be performed prior and post the endoscopic resection (within the same endoscopic session)
