Biliary diseases in dogs are common in veterinary clinical practice and primarily affect elderly animals. Included as changes in the extrahepatic bile ducts are cholecystitis, cholelithiasis, biliary sludge, and gallbladder mucocele. Mostly, the treatment is surgical, and videolaparoscopic cholecystectomy stands out over laparotomy due to its various advantages. There are no retrospective studies on this topic in Brazil, particularly involving video surgery. The main objective of this study is to outline the profile of dogs with biliary disease through epidemiological data, pre-surgical clinical signs, clinicopathological abnormalities, type of biliary alteration, results of bacteriological and/or fungal cultures, histopathological aspects of the gallbladder and liver, and complications during the trans- and immediate post-surgical periods, in order to better understand the disease and assist veterinary clinicians and surgeons in decision-making when facing challenges in managing cases of these diseases. Another objective was to report a rare case involving gallbladder neoplasia in a dog. To this end, 80 medical records of canine patients who underwent videolaparoscopic cholecystectomy between March 2016 and October 2024 were retrospectively evaluated, with these data presented in Article 1. Article 2 reported the case of a dog with well-differentiated gallbladder adenocarcinoma that underwent laparoscopic cholecystectomy, a procedure that had not been previously reported, in addition to the rarity of the histological type found. It is concluded that the breeds most affected in Brazil differed from those reported in the literature, and a large part of the cases were asymptomatic. It is suspected that mucoceles are underreported when only ultrasound is used for diagnosis, as well as endocrinopathies associated with this biliary disease. Laparoscopic cholecystectomy in dogs was effective and safe in the treatment of gallbladder mucocele, cholecystitis, cholelithiasis, as well as gallbladder neoplasms, with a low complication rate. The need for regular check-ups in elderly dogs is emphasized.
