pubmed:abstractText |
Surveillance of patients with Barrett's esophagus or ulcerative colitis for dysplasia is confined to biopsy specimens taken randomly during endoscopy because dysplasia remains undetectable by visual inspection. We attempted to visualize dysplastic tissue during endoscopy after sensitization with 5-aminolevulinic acid (5-ALA) leading to accumulation and formation of protoporphyrin IX and induction of characteristic red fluorescence of the latter substance using blue light illumination.
