![]() Assim, não foi possível associar alterações descritas nos exames histopatológicos quanto à natureza e intensidade das lesões utilizando a colonoscopia, o que leva à conclusão de que é essencial a realização de biópsias em todos os exames para conclusão diagnóstica.Ĭolonoscopia histopatologia intestino grosso íleo caninos endoscopia desordens intestinais Houve baixa concordância entre as classificações por natureza e intensidade dos achados na colonoscopia e histopatologia. Os pólipos hiperplásicos e o linfoma foram as lesões proliferativas de ocorrência mais comum. O cólon ascendente e o reto foram os locais de alterações mais frequentes na colonoscopia e na histopatologia. Quanto à distribuição de lesões por segmento intestinal, houve maior incidência de alterações inflamatórias, das quais foram as mais frequentes, com o infiltrado linfoplasmocitário sendo o mais comum em todos segmentos analisados (i.e. Na colonoscopia, as alterações mais frequentemente observadas foram edema, friabilidade e avermelhamento de mucosa. O objetivo desse estudo retrospectivo foi associar os achados de exames de colonoscopia e histopatologia do intestino grosso e íleo em 54 cães com distúrbios gastrointestinais dos Hospitais Veterinários da Universidade Federal de Minas Gerais (UFMG) e São Francisco de Assis. Quando associada ao exame histopatológico, com a coleta de fragmentos do intestino, o diagnóstico definitivo pode ser obtido. Although the changes observed by colonoscopy and histopathology may not be similar, these techniques are complementary, which makes biopsies mandatory for a diagnostic conclusion.Ĭolonoscopy histopathology canine large intestine ileum endoscopy intestinal disorders dogsĪ colonoscopia é uma técnica pouco invasiva utilizada para avaliação do intestino grosso por meio de inspeção direta da mucosa intestinal. Findings such as edema and reddening of the mucosa were frequent by macroscopy. The most affected sites of the large intestine were the descending colon and the rectum. As for the proliferative and neoplastic lesions, adenomatous polyps and lymphoma were common. The most common finding that reveals inflammatory changes is the lymphoplasmacytic infiltrate. Inflammatory affections are the most frequently observed alterations in the large intestine and ileum of dogs. This was even more evident in the frequency of similar diagnoses in terms of intensity, of which 20 (37.04%) were similar and 34 (62.96%) were different. For the intensity of the injuries, little agreement was observed between the methods (Kappa coefficient = 0.1243, C = -0.05-0.30). This can also be observed when assessing the frequency of similar diagnoses between the methods, since only 39 (72.22%) were consistent, i.e., 15 (22.78%) diagnoses differed depending on the nature of the finding, which could have a great influence on the final diagnosis if histopathology was disregarded. ![]() It was observed a moderate agreement between the classification of the nature of the findings by endoscopy and histopathology (Kappa coefficient = 0.39, CI = 0.20-0.59). The analyses were performed using the Software SAS University Edition. Cohen’s Kappa coefficient was obtained to assess the concordance of nature and intensity classifications between colonoscopy and histopathology, and its 95% confidence interval constructed. ![]() The colonoscopy and histopathological findings of the case series were described using absolute and relative frequencies, as well as nature and intensity classification of the findings. This retrospective study evaluated colonoscopy and histopathological exams of the large intestine and ileum of dogs with gastrointestinal disorders admitted at the Veterinary Hospital of the Federal University of Minas Gerais (UFMG) and the Veterinary Hospital São Francisco de Assis to determine the frequency of injuries, their distribution in the intestinal segments, and the relationship of the findings observed in these two analyzes. When associated with histopathological examination of fragments collected from the intestine, the definitive diagnosis can be obtained. Colonoscopy is a minimally invasive technique used to assess the large intestine through direct inspection of the intestinal mucosa. ![]()
