METHODS: This is a retrospective observational study with of the medical records of all an analysis of all patients A total of 123 patients with rectal lesions were undergoing were evaluated, of rectal polyps.

Histological evaluation showed adenomas in 3.25%, hyperplasia in 7.32%, and hamartoma in 0.81% low-grade dysplasia was identified in 34.96%, high-grade dysplasia in 51.22 %, and adenocarcinoma in 1.63%, while one case (0.81%) was classified as erosion. CONCLUSIONS: Polyps in the rectum are common and were found in 37% of these colonoscoples. Adenomas with dysplasia were the most common form of Colorectal cancer. Therapeutic colonoscopy proved to be a safe and efficient Figure 2 Rectal laterally spreading tumors (chromoscopy, Parada et al.11). method for the complete treatment of rectal lesions
