PRIETO O., Robin Germán et al. Endoscopic and Histopathological Characteristics of Colorectal Polyps Resected Endoscopically at a University Institution in Bogotá D. C. Rev Col Gastroenterol [online]. 2019, vol.34, n.1, pp.31-37. ISSN 0120-9957.  https://doi.org/10.22516/25007440.267.

Colorectal cancer is one of the most important causes of death in Western countries. Since the progression from adenoma to carcinoma was established, it has been considered that colon polyps are an important risk factor for development of colorectal cancer, hence the importance of knowledge and research about them as well as their detection and resection. In our country there had been no prospective evaluations of the characteristics of colorectal polyps, so we considered this study to determine the endoscopic and histopathological characteristics of colonic polyps found and resected through colonoscopy to be of great importance.

This descriptive and observational study includes analysis of polyps resected from patients inthe Gastroenterology and Digestive Endoscopy service of the Clínica Universitaria Colombia. Sample size was calculated probabilistically (n = 306 resected polyps). Contrary to reports in the literature, most of the polyps detected in our study (170) were adenomatous (55.6%). The highest percentage (86%) were tubular which is consistent with the literature. Most of them had low grade dysplasia. Only two of our patients had polyps found whose histology indicated adenocarcinoma.
