The accurate detection and therapy of adenocarcinoma originating from Barrett's oesophagus is challenging as current endoscopic techniques are unreliable for both the detection of high grade intraepithelial neoplasia (HGIN) within Barrett's mucosa and the correct measurement of the dimension of such neoplastic lesions. Confocal laser endomicroscopy (CLE) is a promising technology that could help to close this gap. Relying on first clinical trials of CLE, which showed remarkable results for the detection of Barrett's associated neoplasia, the investigators want to use CLE as targeting tool for endoscopic mucosal resection of HGIN in patients suffering from Barrett's oesophagus. CLE-mapping of neoplastic lesions will be documented and compared to the later performed histological evaluation of the resected specimen. If CLE is passing our challenge this will be another valuable proof of its high potential as reliable new endoscopic technology. Its usage could increase the en-bloc resection rate and decrease the amount of repetitive resections, which would remarkably improve the patients comfort.
