Double cholecystectomy of duplex gallbladder associated with chronic cholecystitis in a cat.

A 6-year-old female neutered Persian cat presented with hyporexia and gradual weight loss over 6 months. Physical examination revealed cranial abdominal pain. Haematology and serum biochemistry were within normal limits. Abdominal ultrasonography and a computed tomography scan suggested a non-neoplastic mass compressing the gallbladder. During an exploratory laparotomy, a duplex gallbladder with two separate cystic ducts was diagnosed intraoperatively. The mass identified using the imaging techniques was an abnormal right gallbladder which was distended with immobile mucoid bile and a thickened wall. The left gallbladder and cystic duct were grossly normal. A cholecystectomy of both gallbladders was performed. Histopathology of the right gallbladder identified chronic cholecystitis. The cat made a good recovery from surgery and reported complete resolution of its hyporexia and a return to normal body weight. This is the first report of a successful cholecystectomy of a duplex gallbladder with chronic cholecystitis of a single gallbladder.

La ecografía como ayuda al diagnóstico decolecistitis en un canino / O ultra-som como ajuda ao diagnóstico da colecistite num canino / The ultrasonography as an assistance to diagnostic of cholecystitis in a canine

La colecistitis es una patología inflamatoria de la vesícula biliar (VB) y la obstrucción e infección biliarserían las causas principales de su presentación. El diagnóstico es difícil, porque tanto los signos clínicoscomo las anormalidades clínico-patológicas son poco específicas, por lo que la ecografía resulta unamodalidad diagnóstica importante, ya que la visualización ecográfica de espesamiento de la pared de laVB o de bilis hiperecogénica induce a la sospecha de colecistitis. El cultivo y antibiograma biliar permitendefinir el tratamiento antibiótico específico. Se describe un caso clínico donde se destaca la importancia dela ecografía en el diagnóstico de la colecistitis canina.

The cholecystitis is a gall-bladder inflamatory patology, the obstruction and biliar infection could be theprincipal causes of presentation. The diagnosis is dificult because the clinical signs as clinicopatologicalabnormalities are inespecifics, so the ultrasonography is a important method of diagnosis, because thevisualization of thickeny of the gall-bladder’s wall or hiperecogenic bile induce to suspect cholecystitis. Thebile culture and antibiograma permit to define the specific antibiotic treatment. A clinic case is described toemphasize the importance of ultrasonography in the canine cholecystitis diagnosis.
