title: [Villous adenoma: clinical, endoscopic and histopathologic aspects].
abstract: A ten years retrospective study of villous adenomas at the Arzobispo Loayza Hospital was carried out. 24 patients with this problem were found, the mean age was 62 years, clinical symptoms were: rectal bleeding (87.5%), mucus diarrhea (58.2%) and abdominal pain (37.5%). According to the Histopathologic study, there were 14 (58%) adenomas with carcinoma and the existence of carcinoma was proportional to the adenoma's size, we didn't find carcinoma in the adenomas smaller than 2 cm. The endoscopy was useful to detect invasive carcinoma in the 88% of cases meanwhile the endoscopic biopsy detected only 27% of cases. The endoscopic polipectomy was suitable when the adenomas were smaller than 3 cm.
