title: Photodynamic therapy for Barrett's oesophagus: How I do it.
abstract: Endoscopic photodynamic therapy (PDT) for Barrett's oesophagus with high-grade dysplasia or early carcinoma is undertaken after full investigation. Endoscopic assessment is mandatory to determine the extent of the Barrett's segment and neoplastic changes. Photofrin at 2mg/kgbw is used, followed 24-72h later by illumination of 630nm light, 200J/cm of lesion. The whole of the Barrett's segment should be exposed to illumination. Patients are followed up endoscopically at 3 months.
