Endoscopic Therapy of Barrett's Esophagus and Superficial Cancer

摘要

Ablative therapies for Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) offer the possibility of removal of neoplastic tissue without the risk of surgery. There has recently been increased interest in this approach with the development of novel modalities for ablative therapy. Data demonstrate that complete reversion to neosquamous epithelium is achievable in most patients. However, data demonstrating a decrease in cancer risk following these therapies are scarce because most studies do not have the statistical power or comparator groups available to assess any changes in risk of cancer death.
