DEL VALLE LLUFRIO, Pedro; ROMERO BAREIRO, Sandra Rocío    SANTANA FUENTES, Yenia. Colon lesion diagnosed by colonoscopy in patients with hidden positive blood. []. , 36, 1, pp. 692-699. ISSN 1684-1824.

We carried out an observational, descriptive, cross-sectional study to all the patients with hidden positive blood in fecal feces who were submitted to colonoscopy in the gastroenterology service of the Teaching Clinic-Surgical Hospital Faustino Pérez, of Matanzas, in the period from June 2013 to June 2014; the universe were 104 patients who gave their previous informed consent, and the aim was characterizing the diagnosed lesions. We elaborated a form for collecting information (age, gender, colonoscopy positivity and diagnosed lesions). Results were given in numbers and percents and displayed in tables and pictures. We arrived to the conclusion that there was a predominance of female patients aged 50-55 years; 76,92 % of them had some kind of colon lesions; 15,09 % had colon cancer and 2,83 % rectum cancer, confirming the importance of this  testing method for the precocious diagnosis of these pathologies.
