Cromoendoscopia Virtual y Magnificación Endoscópica: diagnostico precoz del carcinoma de células escamosas del canal anal
Resumen
El canal anal es la porción distal del tracto digestivo y mide entre 2,5 a 4 cm. de longitud. El cáncer del canal anal es una enfermedad relativamente rara, siendo el carcinoma de células escamosas el más frecuente, con una sobrevida de 5 años de aproximadamente 58%. En los años recientes existe un aumento en la incidencia y prevalencia de la neoplasia intraepitelial y del cáncer del canal anal.
El diagnóstico temprano de la neoplasia intraepitelial y del cáncer precóz del canal anal, permite una adecuada estrategia terapéutica curativa.
La endoscopia mediante la técnica de la cromoendoscopia virtual y magnificación endoscópica, logra la detección y caracterización de la neoplasia intraepitelial y del carcinoma precoz de células escamosas del canal anal, mediante la observación de las alteraciones en la arquitectura microvascular subepitelial, con alta seguridad diagnóstica. Se presenta la experiencia con 4 pacientes con carcinoma precóz de células escamosas del canal anal, detectados por cromoendoscopia virtual + magnificación y su correlación endoscópica e histológica.
