Intestinal lymphangiectasia in a dog

A case of intestinal lymphangiectasia in a 3-year-old female Dalmatian is described. The clinical examination, laboratory findings, histology of the small intestine and necropsy findings are discussed.     

Intestinal lymphangiectasia with lipogranulomatous lymphangitis in a dog

Intestinal lymphangiectasia with lipogranulomatous lymphangitis was diagnosed at necropsy in a 6.5-year-old Maltese dog that had a history of bouts of vomiting, abdominal distention, and diarrhea. The condition was attributed to trauma to the pleural and peritoneal cavities received from bite wounds inflicted one year previously.     

Intestinal choristoma in the subcutis of a dog

A 2-year-old, spayed female, Labrador Retriever-cross presented with a subcutaneous mass of several weeks' duration in the right flank region. Surgical excision and histologic examination were performed. The 1.0-cm-diameter mass was circumscribed, unencapsulated, and cystic with a bilayer wall. The inner layer resembled intestinal mucosa, including a tall columnar lining epithelium, crypt-like glands containing scattered neuroendocrine cells that were strongly immunopositive for synaptophysin, and a supporting lamina propria-like fibrovascular tissue that contained lymphocytes and plasma cells. The outer layer was 1- to 2-mm thick and was composed of intersecting and blending bundles of smooth muscle and collagen. Given the presence of organized intestinal tissues in the subcutis, the lesion was consistent with intestinal choristoma.     

Protein-losing enteropathy in a dog with lymphangiectasia,lymphoplasmacytic enteritis and pancreatic exocrine insufficiency

This is a report of seven-year-old male Akita mixed dog, with protein-losing enteropathy (PLE). He had a history of chronic vomiting and diarrhea with anorexia/hyporexia. Previously he suffered acute abdomen about eight months prior to this visit. Our dog showed uncommon combination of diseases that could cause PLE since it was affected by inflammatory bowel disease (IBD), intestinal lymphangiectasia (IL), and exocrine pancreatic insufficiency (EPI). The dog had most of the abnormalities found in IL, as well as hypoalbuminemia, hyperglobulinemia, lymphopenia, hypocalcemia, and hypercholesterolemia. During endoscopy exam, we found changes characteristic of IL such as irregular small white spots. We took biopsies from stomach, duodenum, and cecum. These biopsies showed infiltration by lymphocytes and plasmatic cells in the lamina propria also, the duodenal biopsies showed moderate dilation of the lymphatic vessels. The patient had 2.1?µg/mL of TLI, this result was compatible with EPI. We assume that the first pathology in this animal was IBD, which caused chronic pancreatitis (CP) that in turn progressed to EPI. It is also possible that IL was secondary to IBD. We have reported for the first time the correlation of IBD and EPI in dogs. This should change our approach to treating chronic diarrhea in dogs. Therefore, we propose that dogs diagnosed with EPI should also be subjected to endoscopy and intestinal biopsy. Similarly, to rule out secondary EPI, TLI should be measured routinely in dogs with IBD.     

Intestinal choristoma in the midcervical region of a dog

A 5-year-old, neutered male, mixed-breed dog was evaluated for a fluctuant mass in the right midcervical region. The mass recurred following aspiration of its contents and after removal of the right sublingual and mandibular salivary glands. The lateral midcervical location of the mass and the serous nature of the fluid within the mass were inconsistent with a salivary mucocele. Excisional biopsy was curative and revealed an intestinal choristoma.     

Intestinal strangulation caused by intra-abdominal lipomas in a dog.

Pedunculated, intra-abdominal lipomas caused intestinal strangulation in a Doberman Pinscher. The dog was treated surgically to remove the lipomas and the devitalized intestine but died soon after surgery. Histologic evaluation confirmed the diagnosis of lipoma.     

Intestinal malabsorption and cryptosporidiosis in an adult dog

Chronic intestinal cryptosporidiosis was diagnosed as the cause of chronic diarrhea and weight loss in an adult dog without obvious signs of immunosuppression. Results of tests for digestive function suggested that the dog had impaired intestinal absorption or bacterial overgrowth. The nutrient malabsorption might have resulted in or have been caused by the cryptosporidiosis. Temporary clinical improvement without reduction in fecal oocyst concentration was noticed following treatment with clindamycin. The dog was euthanatized. At necropsy, the dog was found to have chronic lymphoplasmacytic enteritis and cryptosporidiosis. A veterinary student that worked in the ward where the dog was kept developed cryptosporidal diarrhea.     

Intestinal obstruction in a dog due to incarceration of small intestine in a coccygeal fracture

A case of dorsal rupture of the abdominal wall with prolapse, incarceration and partial obstruction of small bowel in a 2-year-old dog is reported. The diagnosis was made and confirmed radiographically by an upper gastrointestinal barium study and the defect was corrected surgically. The dog made an uneventful recovery. Résumé. On a rapporté, chez un chien de deux ans, un cas de rupture dorsale de la paroi abdominale avec prolapsus, incarcération et obstruction partielle de l'intestin grêle. Le diagnostic a été fait et confirmé par radiographie au moyen d'une étude de baryum dans la partie supérieure gastro-intestinale et le défaut a été corrigé chirurgicalement. Le chien s'est rétabli normalement. Zusammenfassung. Ein Fall von dorsalem Riss der Bauchdecke mit Prolaps, Inkarzeration und Teilobstruktion des Dünndarms wurde von einem 2-jährigen Hund berichtet. Die Diagnose wurde getroffen und röntgenologisch mit einer ober-gastro-intestinalen Barium Untersuchung bestätigt. Das Gebrechen wurde chirurgisch beseitigt und der Hund erholte sich, ohne weiteren Zwishenfall.     

宠物犬肠梗阻修复术

宠物犬乱吃物品的情况比较多见,特别是吃进难以消化或不消化的物品,这些物品进入胃肠道后造成肖肠道梗阻,会引起剧烈腹痛,可继发胃肠痉挛、肠套叠、胃肠道坏死、肠破裂、脏腑粘连等,严重时可危急宠物人的生命.现介绍1例宠物犬由于误食抹布引起的肠梗阻病例.     

Intestinal haemorrhage associated with colonic vascular ectasia (angiodysplasia) in a dog

An eight-year-old, sexually intact, male, 37 kg crossbred dog was referred for investigation of two acute episodes of intestinal bleeding and severe anaemia within a five-month period. There was no evidence of coagulopathy or underlying systemic disease. Technetium-labelled red blood cell scintigraphy suggested the colon as the site of bleeding. Colonoscopy identified a focal area of dilated and tortuous mucosal blood vessels. Histopathology of the resected colon revealed vascular ectasia (angiodysplasia). At nine months post-resection, the dog remained healthy and free of any overt intestinal haemorrhage.
