Colecistectomía asociada a enterotomia duodenal en una infestación por Platynosomum sp. en un gato doméstico / Cholecystectomy associated to duodenal enterotomy in the infestation by Platynosomum sp. in a domestic cat / Colecistectomia associada à enterotomia duodenal na infestação por Platynosomum sp. em um gato doméstico

Platynosomum sp. es el más grande parásito hepatobiliar de la familia Felidae, causador de una lesión obstructiva extrahepática que puede ser tratada por cirugía. Un felino, sin raza definida, dos años de edad, semidomiciliado, fue atendido con un cuadro clínico de apatía, ictericia, deshidratación y elevación de enzimas hepáticas. En la ecografía abdominal se observó el hígado aumentado, vasos hepáticos y la vena porta con un mayor diámetro, la vesícula llena de contenido anecoico, sedimentación, espesamiento y hiperrefringencia de la pared de el conducto biliar principal dilatado con pared gruesa. Fue realizada colecistectomía con enterotomia duodenal. La inspección de los contenidos de la vesícula biliar reveló parásitos con una apariencia aplanada y la evaluación microscópica fue consistente con Platynosomum sp. El tratamiento con niclosamida y oxibendazol fue efectivo. Colecistectomía asociada con enterotomia duodenal es eficaz en tales casos.

Platynosomum sp. is the major hepatobiliary parasite of felids, causing an extra-hepatic obstructive lesion which may be treated by surgery. A two-year old cross-bred feline, semi-domiciled, was attended with a clinical picture of apathy, jaundice, dehydration and increase in hepatic enzymes. In the abdominal ultrasonography the liver was observed enlarged, hepatic and portal veins with increased diameter, gall bladder filled by anechoic content, with sediment, thickening and hyperechogenicity of the wall and a dilated main bile duct with a thickened wall. The cholecystectomy with a duodenal enterotomy was performed. The inspection of the gall bladder’s content revealed parasites with a flattened aspect and the microscopic evaluation was compatible with Platynosomum sp. A treatment with niclosamide and oxibendazole was efficient. Cholecystectomy associated to a duodenal enterotomy is efficient in these cases.

Um felino, de dois anos de idade, sem raça definida, semidomiciliado, foi atendido apresentando um quadro clínico de apatia, icterícia, desidratação e aumento de enzimas hepáticas. Na ultrassonografia abdominal o fígado estava aumentado, vasos hepáticos e veia porta com aumento de diâmetro, vesícula biliar preenchida por conteúdo anecoico, com sedimentação, espessamento e hiperecogenicidade da parede e ducto biliar principal dilatado com parede espessada. Realizou-se a colecistectomia com enterotomia duodenal. A inspeção do conteúdo da vesicular biliar revelou parasitos com um aspecto achatado e a avaliação microscópica foi compatível com Platynosomum sp. O tratamento com niclosamida e oxibendazole foi eficiente. Colecistectomia associada à enterotomia duodenal é eficiente nesses casos.

Cholangitis and Cholangiohepatitis in Dogs: A Descriptive Study of 54 Cases Based on Histopathologic Diagnosis (2004-2014).

BACKGROUND: Cholangitis in dogs appears to be more common than previously thought, but understanding of the disease remains incomplete. OBJECTIVE: To describe a population of dogs with cholangitis or cholangiohepatitis. ANIMALS: Fifty-four client-owned dogs with cholangitis or cholangiohepatitis. METHODS: Medical records of dogs with cholangitis or cholangiohepatitis confirmed by histopathology between January 2004 and December 2014 were identified using a computer-based search and retrospectively reviewed. RESULTS: Clinical signs included vomiting (72.2%), lethargy (70.4%), and inappetence (64.8%). Most dogs (49/50) had increased liver enzyme activities, hyperbilirubinemia (32/50), and hypercholesterolemia (24/43). Ultrasonographic abnormalities of the hepatobiliary system were seen in 84% of cases. On histopathology, 53 of 54 affected dogs had neutrophilic cholangitis (NC) or cholangiohepatitis, whereas 1 dog had lymphocytic cholangitis. Most cases (42/54) were chronic. Evidence of concurrent biliary disease (46.2%) and biliary tract obstruction (42.6%) was common. Seventeen of 36 biliary and 11 of 25 liver cultures were positive for bacterial growth; Escherichia coli and Enterococcus spp. were most common. Median patient survival was 671 days (95% confidence interval [CI]: 114-1,426). On Cox regression, dogs that did not have a cholecystectomy performed had a 2.1 greater hazard for death (P = 0.037; 95% CI: 1.0-4.3) compared to cholecystectomized dogs. Dogs >13 years old had a 5.0 greater hazard for death (P = 0.001; 95% CI: 1.9-13.2) compared to younger dogs. CONCLUSIONS AND CLINICAL SIGNIFICANCE: Chronic NC or cholangiohepatitis was most common. Cholecystitis and biliary tract obstruction often occurred in conjunction with cholangitis. Cholecystectomized dogs had decreased risk of death; thus, cholecystectomy may improve patient outcome.

Colecistite necrosante em um cão: relato de caso / Necrosant cholecystitis in a dog: report Case

Objetiva-se com esse relato, descrever um caso de colecistite necrosante em um cão, fêmea, da raça Yorkshire Terrier. O paciente deu entrada no Hospital Veterinário da UNIJUÍ, apresentando vômito e diarreia escura. Através do exame de ultrassonografia, evidenciou vesícula biliar com parede em dupla camada e com formato irregular, sugerindo-se uma colecistite necrosante. Diante disso, o canino foi encaminhado para uma colecistectomia, como forma de tratamento. Esse relato salienta a importância do diagnóstico rápido e correto dea doença, sendo que isso foi determinante para o estabelecimento do tratamento adequado e recuperação do animal em questão.

The objective of this paper is to describe a necrosant cholecystitiscase in a female dog, York Shire Terrier breed. The patient was admitted to the Veterinary Hospitalof UNIJUÍ, presenting vomiting and dark diarrhea. Ultrasonography showed a biliary vesicle with an irregularly shaped double-layer wall, suggesting a necrosant cholecystitis. Therefore, the canine was referred to a cholecystectomy as a form of treatment, where the gallbladder was excised. This paper emphasizes the importance of the rapid and correct diagnosis of this disease, and this was determinant for the establishment of appropriate treatment and recovery of the animal in question.
