“…Granularity has never been reported as a feature of the ileum affected by CIE, but ileal lymphangiectasia has been described previously in 3 dogs from a small sample of 10 with gastrointestinal disorders. 18 We showed that endoscopic lesions, such as erosions, lymphangiectasia, and particularly mucosal friability, were more likely, and gross ileal injury was significantly greater in dogs with CIE when the cobalamin concentration was <200 ng/L than when it was >350 ng/L. our study, it might be expected that as cobalamin approaches the upper margin, the characteristics of the ileum resemble more closely those of normocobalaminemic dogs and vice versa.…”

Background It has not been determined whether ileal appearance differs among dogs with chronic inflammatory enteropathy (CIE) and different serum concentrations of cobalamin. Objective To compare endoscopic and histologic ileal findings in dogs with CIE and different serum cobalamin concentrations and then evaluate the correlation of ileal changes to cobalamin serum concentration using updated scoring systems to assess the ileum. Animals Sixty‐eight dogs with CIE. Methods Retrospective study. Frequency of ileal features and ileal histologic and endoscopic scores (IHS and IES) were obtained and compared among CIE dogs with severe hypocobalaminemia (SHC; <200 ng/L), hypocobalaminemia (HC; 200‐350 ng/L), or normocobalaminemia (NC; >350 ng/L). The correlation of IHS and IES with cobalamin was evaluated. Results Friability, villus atrophy, crypt dilatation, epithelial injury, and intraepithelial lymphocytes were more frequent in SHC than in NC dogs (all P ≤ .01). Median SHC‐IES (2; range, 0‐4) was higher than NC‐IES (1; range, 0‐5; P = .004). Median SHC‐IHS (6; range, 3‐9) was higher than HC‐IHS (4; range, 1‐7; P < .001) and NC‐IHS (3; range, 1‐8; P < .001). Cobalamin concentration correlated negatively with IES (ρ = −.34, P = .005) and IHS (ρ = −.58, P < .001). Conclusions and Clinical Importance Ileal features and involvement degree markedly differed when cobalamin was <200 or >350 ng/L in CIE dogs. With updated scales to assess the mucosa, greater ileal damage was associated with lower serum cobalamin concentration.

The article is devoted to the quantitative characteristics of the small intestine wall layers echoicity of dogs with parvoviral enteritis, their ratio and comparison of the results with the index of healthy animals intestinal echoicity. The object of the study was 53 heterogeneous dogs of both sexes with confirmed polymerase chain reaction diagnosed with parvoviral enteritis at the age from 6 weeks to 7 months. The studies were carried out at the Pirogov Veterinary Center of Stavropol and SD&TVC at FSBEI HE “Stavropol State Agrarian University” on the SIUI Apogee 1100 scanner (Shantou Institute of Ultrasonic Instruments Co., Ltd., Guangdong, China) according to the generally accepted method using a multi-frequency linear sensor with a frequency of 7-12 MHz in B-mode. It was found that each layer of the jejunal wall (mucous, submucosal and muscular) of examined dogs was homoechoic and the intestine echoicity index of sick dogs increased for the mucous layer - 2.54 times, submucosal - 1.1, and muscle - in 1.3 times compared with healthy animals’ index. Intestinal echoicity index determination provides objective information about changes in the main ultrasound parameter during ultrasound of alimentary tract structures.

Lymphangiectasia is a heterogenous inflammatory bowel disease characterized by lymphatic vessel dilation, chronic diarrhea and protein loss such as serum albumin and globulin. The most common cause of lymphangiectasia is considered to be the congenital malformation of the lymphatics. The study was conducted between 2012-2015 on 76 dogs suffering from intestinal disorders and manifesting digestive symptoms such as diarrhea or weight loss. In order to assess the origin of disorder, physical examination, biochemistry profile, ultrasound and endoscopic examinations were performed. Ultrasound examination tried to assess the changes of intestines’ echogenicity, changes in wall thickness, wall layering and presence of striations or / and speckles (hyperechoic structures along intestinal mucosal layer). Endoscopic examination ﬁndings included dilated lacteals (59.2%) and erythema (21.1%). Although increased friability was observed in 33 dogs, it was not considered in the study due to limitations represented by the evaluation of the endoscopic images only. The study proved that an extremely significant statistical correlation exists between the presence of speckles and dilated lacteals in dogs with lymphangiectasia (P<0.05). Up to now, there is no other study to make an association between the white spots observed in ultrasound examination and dilated lacteals revealed after endoscopy in dogs with intestinal lymphangiectasia.
