RESUMEN
AIM: To know the more detailed findings of the small intestinal mucosa with the use of a magnifying endoscope and a vital dye, and the efficacy of the both tools. PATIENT AND METHODS: A 54-year old female patient with celiac disease. The duodenal mucosa downward as far as the descending portion was observed with a magnifying endoscope (Olympus GIF HM) before and after spraying the mucosa with 0.1 percent indigo carmine. RESULTS: The endoscopy clarified the atrophy and edema of each villus, and scattering of the dye revealed shorter villi with the relatively longer villi remaining in islands. CONCLUSION: The combination of magnifying endoscopy and the dye scattering method is useful for closer observation of the intestinal mucosa in celiac diseases
