It is not an uncontrolled tear in the lining. The idea came from cholera research. Vibrio cholerae makes zonula occludens toxin, or Zot. Zot […]

Barrett’s Ablation Techniques Barrett’s esophagus replaces the normal squamous lining of the distal esophagus with columnar epithelium. Intestinal metaplasia in that lining raises the risk of dysplasia and adenocarcinoma. Ablation aims to destroy the abnormal mucosa so squamous epithelium can grow back. Doctors first confirm the diagnosis with endoscopy and biopsy. Ablation is usually reserved […]
