Ультрасонографические предпосылки и обоснование стадий развития лимфомы кишечника у кошек

Abstract

According to the literature, intestinal lymphoma is currently the most common tumor disease of the digestive canal in cats and is characterized by a severe course and poor response to chemotherapy. Because this tumor shares clinical and ultrasound characteristics with inflammatory bowel disease, diagnosis is challenging and requires a number of complex procedures that often cannot be performed without sedating the animal. In connection with the above, the purpose of this work was to identify ultrasonographic prerequisites for intestinal lymphoma in cats and substantiate the stages of development of intestinal lymphoma in cats. The objects of the research were cats of various breeds (34 animals in total), various sex and age groups. All animals underwent a clinical examination using standard methods, as well as ultrasonographic examination of the abdominal cavity. Ultrasound studies revealed such changes as thickening of the intestinal wall, a change in the ratio of layers with partial or complete loss of differentiation of the intestinal layers, a decrease or increase in the echogenicity of the layers of the intestinal wall, heterogeneity of the echostructure, deformation of the lumen with the presence of heterogeneous anechoic contents, impaired peristalsis, a local increase in the echogenicity of the surrounding fatty tissue. tissue, pronounced enlargement of lymph nodes with changes in their echostructure and echogenicity, the presence of free fluid in the abdominal cavity. The diagnosis was confirmed using cytological and histological studies.
