Análise de ressecções colonoscópicas de pólipos colorretais em um Centro de Referência no interior do Sul do País

Abstract

Introduction: Colorectal cancer presents a high incidence and mortality, deriving in most cases from polypoid adenomas, having the colonoscopy with polypectomy as an effective preventive method. Objective: To verify the epidemiological, endoscopic and histological aspects of colorectal polyps in patients submitted to colonoscopy by several indications in the Endoscopy Service of Hospital São Vicente de Paulo / Passo Fundo, RS. Method: This is a quantitative, observational, cross-sectional, descriptive 31

study. In a total of 3116 patients, all the colonoscopy reports were analyzed, and those with polyps and / or flat-lesions were selected at the Endoscopy Service of Hospital São Vicente de Paulo - Passo Fundo / RS in the period 2014-2015 and evaluated histopathological examinations.The analyzed variables were: sex, age, indication, location, size, base, histological type and presence of dysplasia. Results: Out of the 3,116 tests analyzed, 538 colorectal polyps were found in 386 patients, 45.1% male, 54.9% female. The mean age was 59.84 years, with extremes of 24 and 89 years. The most frequent location was in the sigmoid colon 37,8%; 52.4% measured up to 5mm and 89.8% were sessile. As for histology, the majority were adenomatous (74.9%), being tubular in 88.6% and low in 98.5%. Three adenocarcinomas were found Conclusion: Tubular adenomas are the most frequent polyps, and high-grade lesions occur with a higher incidence of tubular-villous, pediculated lesions and greater than 5mm, and, due to the risk of malignancy, colonoscopy with polypectomy is important for reducing the incidence of colorectal cancer
