ENDOSCOPIC-PATHOLOGICAL CORRELATION OF RE CTOCOLONIC LESIONS LESS-THAN 10 MM IN DIAMETER

Ninety eight rectocolonic lesions up to 10 mm in diameter found in 50 patients were analyzed. The relationship between endoscopic and pathol ogic diagnosis was established. Emphasis was made on the detection of adenomas based in the following: Yamada III or IV lateral vision, Yama da I and II with smooth but erythematous surface, and in pale with irr egular surface lesions. The sensitivity of the method was 92% and the specificity was 72% for adenomas. Six percent of adenomas were pale, w ith mucuous hypersecretion on histopathology, and can be mistaken for hyperplastic polyps. This mucous hypersecretion correlates with low gr ade dysplasia, wich supposedly indicates a lower evolutive risk.
