The etiology of canine gallbladder mucocele (GBM) has not yet been identified. However, several studies have linked GBM in dogs to particular breeds (Shetland Sheepdogs are commonly implicated), concurrent endocrine disease (hyperadrenocorticism and/or hypothyroidism), and a mutation in the canine ABCB4 gene (ABCB4 1583_1584G), particularly in Shetland Sheepdogs. The current study assessed ABCB4 1583_1584G, in a wider sample of dogs with GBM compared with age and breed-matched controls. Read More

The association between gall bladder mucoceles and hyperlipidaemia in dogs: a retrospective case control study.

Vet J 2014 Jan 26;199(1):76-9. Epub 2013 Oct 26.

Department of Veterinary Internal Medicine, Graduate School of Agricultural and Life Sciences, The University of Tokyo, 1-1-1, Yayoi, Bunkyo-ku, Tokyo 113-8657, Japan.

The diagnosis of gall bladder mucoceles (GM) in dogs has become increasingly frequent in veterinary medicine. Primary breed-specific hyperlipidaemia is reported in Shetland Sheepdogs and Miniature Schnauzers, breeds in which GM are known to occur more frequently than in other breeds. The objective of this study was to evaluate the association between GM and hyperlipidaemia in dogs. Read More

Routine histopathology of gallbladder after elective cholecystectomy for gallstones: waste of resources or a justified act?

BMC Surg 2013 Jul 8;13:26. Epub 2013 Jul 8.

Department of Surgery, Liaquat University of Medical & Health Sciences, Jamshoro 71000, Pakistan.

Background: Selective approach for sending cholecystectomy specimens for histopathology results in missing discrete pathologies such as premalignant benign lesions such as porcelain gallbladder, carcinoma-in-situ, and early carcinomas. To avoid such blunders therefore, every cholecystectomy specimen should be routinely examined histologically. Unfortunately, the practice of discarding gallbladder specimen is standard in most tertiary care hospitals of Pakistan including the primary investigators' own institution. Read More

Decreased gallbladder emptying in dogs with biliary sludge or gallbladder mucocele.

Vet Radiol Ultrasound 2012 Jan-Feb;53(1):84-91

Department of Veterinary Internal Medicine, Graduate School of Agricultural and Life Sciences, The University of Tokyo, Tokyo Japan.

Biliary sludge in dogs is dismissed commonly as an incidental finding. On the other hand, gallbladder mucocele is reported increasingly in dogs and can lead to biliary obstruction or gallbladder rupture. Cholestasis is suspected to play a role in development of sludge and mucoceles, though there are no data in dogs to support this. Read More

Effects of iatrogenic hypercortisolism on gallbladder sludge formation and biochemical bile constituents in dogs.

Vet J 2012 Feb 12;191(2):225-30. Epub 2011 Feb 12.

Clinic for Small Animal Internal Medicine, Vetsuisse Faculty, University of Zurich, 8057 Zurich, Switzerland.

An association between gallbladder mucoceles and hypercortisolism (HC) was recently described in dogs. Because the formation of a mucocele from clear bile without the transitional formation of microprecipitates appears unlikely, the aim of this study was to investigate the effects of iatrogenic HC on sludge formation and changes in the biochemical composition of bile. Bile samples from 6 dogs obtained by percutaneous ultrasound-guided cholecystocentesis before (day 0), during (days 28, 56, and 84), and after (days 28p, 56p, and 84p) oral administration of hydrocortisone (8 mg/kg every 12 h) were analysed for calcium, cholesterol and bilirubin concentrations and pH.

An insertion mutation in ABCB4 is associated with gallbladder mucocele formation in dogs.

Comp Hepatol 2010 Jul 3;9. Epub 2010 Jul 3.

Department of Veterinary Clinical Sciences, College of Veterinary Medicine, Washington State University, Pullman, WA 99164-6610, USA.

Background: ABCB4 functions as a phosphatidylcholine translocater, flipping phosphatidylcholine across hepatocyte canalicular membranes into biliary canaliculi. In people, ABCB4 gene mutations are associated with several disease syndromes including intrahepatic cholestasis of pregnancy, progressive familial intrahepatic cholestasis (type 3), primary biliary cirrhosis, and cholelithiasis. Hepatobiliary disease, specifically gallbladder mucocele formation, has been recognized with increased frequency in dogs during the past decade. Read More

Correlation between ultrasonographic imaging of the gallbladder and gallbladder content in eleven cholecystectomised dogs and their prognoses.

J Vet Med Sci 2009 Oct;71(10):1295-300

Uno Animal Hospital, 181-3 Yamadai, Kinsei-cho, Ehime Prefecture 799-0112, Japan.

A comparison was performed between preoperative ultrasonographic and macroscopic findings for gallbladders and their contents in eleven dogs that were found to have any content in the gallbladder and then underwent cholecystectomy. In addition, correlation was considered between prognosis and age, hematologic analysis, serum biochemical analysis and ultrasonographic findings. Ultrasonographic findings of the gallbladder were classified into 3 patterns: 1) hyperechoic content filling the entire gallbladder and precipitated immobile content, 2) a somewhat thinner hypoechoic area in the exterior layer with a less distinctive border adjacent to the internal hyperechoic area than pattern 3 with moth-eaten or mosaic-form hypoechoic portions scattered within the internal hyperechoic area and 3) a thick hypoechoic area in the exterior layer with a distinctive border adjacent to a prominent internal hyperechoic area.
