The occurrence of colon cancer typically depends on the presence or absence of adenomatous polyps. Hence, performing colonoscopy and polypectomy can aid in cancer prevention. This study aimed to retrospectively investigate demographic, endoscopic, and histopathological data of patients who presented with colorectal polyps and underwent endoscopic resection at our center. In this single-center retrospective study, we collected the data of 1058 colorectal polyps that were excised from 498 cases between September 2019 and September 2020. We reviewed patient’s information, including patient age and sex, indications for colonoscopy, polyp characteristics (localization, size, number, and histopathology), endoscopic resection techniques, and presence of related complications. Mean age of the 498 cases included in this study was 62.44 ± 11.77 years (21–90 years); among these patients, 296 (59.4%) were females. The age group of 60–69 years had the highest number of cases (150 cases) presenting with polyps (30.1%). The most common indication for colonoscopy was polyp surveillance in 100 cases (20.1%). The polyps were most commonly localized in the sigmoid colon (26%). Histopathologically, the most common type of polyp was tubular adenoma. Furthermore, 54.3% of the polyps were diminutive. Polyps with dysplasia were significantly different from those without dysplasia in terms of polyp size, polyp localization, and post-polypectomy complications (p < 0.001, p = 0.006, and p < 0.001, respectively). In people aged >50 years, colon polyps were more common in the left colon, especially in the rectosigmoid region. Endoscopic polypectomy is a safe method for resecting precancerous lesions. Polypectomy should be performed immediately after identifying polyps in colonoscopy screenings to determine their histology and prevent progression to malignancy. Additionally, these patients should be included in a polyp surveillance program.

Key words: Colonoscopy, colorectal polyp, polypectomy, adenoma, dysplasia
