MONSERAT, Raúl et al. Focos de criptas aberrantes correlación endoscópico-morfológica con el  uso de Endoscopios de alta resolución sin magnificación. Gen [online]. 2008, vol.62, n.2, pp.133-136. ISSN 0016-3503.

In our study, we used standard high resolution colonoscope to describe aberrant crypt foci. Aberrant crypt foci are either flat or slightly elevated lesions with a 1 to 4 mm of diameter with central depression. Usually these foci have been close to adenomas. Once the lesion was identified, it was first irrigated with 0.5% of acetic acid to remove mucus from the surface. After 30 seconds it was irrigated again with 0.5 % methylene blue or 0.5 to 1% indigo carmine. We tried to classify the lesion based on the literature criteria and compare it with the histopathology diagnosis. 40 patients were evaluated in this study, 67, 5 % of the aberrant crypt foci were located in rectosigmoid colon. We found direct histopathologic and endoscopic correlation between dysplasic aberrant crypt foci and high association with polyps.
