ABSTRACT

La endoscopia estándar no identifica esófago de Barrett. Esta limitación disminuye con magnificación endoscópica, coloración vital y/o virtual que permite observar los patrones de mucosa sugestivos de metaplasia intestinal. Identificar metaplasia intestinal con magnificación endoscópica y cromoscopia virtual realizada con "Flexible Spectral Imaging Colour Enhancement" (FICE) corroborándola con histología. Pacientes: Previo consentimiento se incluyeron a los individuos con indicación electiva de endoscopia digestiva superior. Se realizó endoscopia digestiva superior con equipo Fujinon Inc. EG 590 ZW, y procesador EPX 4400. Consecutivamente se practicó endoscopia con: a) alta resolución, b) FICE, c) alta resolución, d) magnificación, e) FICE y f) alta resolución. Cada patrón encontrado se grabó, se fotografió y se guardó en JPEG en programa Power Point. Los patólogos evaluaron la biopsia del patrón observado sin tener datos del paciente. Se incluyeron 30 pacientes: 11 hombres y 19 mujeres con rango de edad 20-83 años y promedio 51,73 años. Solo con magnificación sola o con cromoscopia virtual se observaron los patrones de mucosa. En el tipo 3 se diagnosticó esófago de Barrett en 33,33% y en ninguno de los otros. Conclusión: La magnificación endoscópica y cromoscopia virtual con FICE identifica metaplasia intestinal y diagnostica esófago de Barrett


Standard endoscopy does not identify Barrett's esophagus or mucosa patterns suggestive of intestinal metaplasia. Endoscopic magnification, vital and or virtual chromoscopy reduces this limitation. Aim: Identify intestinal metaplasia with endoscopic magnification and Flexible Spectral Imaging Colour Enhancement (FICE) corroborating it with histology. Patients: Individuals scheduled to undergo routine upper gastrointestinal endoscopy were enrolled. Upper gastrointestinal endoscopy was performed with Fujinon Inc. 590 EG ZW and EPX 4400 processor. Endoscopy was consecutively performed with: a) high resolution, b) FICE, c) high resolution, d) magnification, e) FICE, f) high resolution. Each found pattern was recorded, was photographed and was saved in JPEG in program Power Point. Biopsy was obtained of the predominant pattern and the pathologist assessed without patient information. Results: 30 patients were included, 11 men and 19 women with 20-83 years and 51.73 years average age range. Patterns of mucosa were observed only with magnification and virtual chromoscopy, Barrett's esophagus was diagnosed in 33.33% of type 3 and none in type 1 and 2. The endoscopic magnification and virtual chromoscopy with FICE identifies intestinal metaplasia and let diagnose Barrett's esophagus.
