Interventions

From November 2010 to August 2012 Following the detection of colorectal lesions in WL observation, the lesions were diagnosed for neoplastic or non-neoplastic. In autofluorescence mode, color-tone

1.01 are judged to be neoplastic and that with G/R of &gt

1.01 are considered to be non-neoplastic. Consecutively, all lesions analyzed in the present study are endoscopically removed or biopsied and the specimens are submitted to pathologic evaluation. Fi
