As Barrett´s esophagus is supposed to be the most important risk factor for the development of esophageal adenocarcinoma, endoscopic-bioptic follow-up is recommended regularly for all patients with Barrett´s esophagus. However, according to recent studies Barrett´s esophagus rarely progresses to carcinoma, therefore many experts consider the current surveillance programs cost-ineffective. Hence, based on long-term follow-up-examiations of 1438 patients with Barrett´s esophagus, it was intended here to examine the development of malignant Barrett´s esophagus. The results of this dissertation indicate that Patients with initial low-grade intraepithelial neoplasia significantly develop malignant Barrett´s esophagus more frequently than patients without initial intraepithelial neoplasia. Furthermore, malignant progressions were predominantly detected during the first year of follow-up.
