gallbladder mucocele dog treatment
The treatment of choice for a dog with extrahepatic biliary tract (EHBT) obstruction or peritonitis due to a gallbladder mucocele is surgical. If the mucocele is infected, your vet will give you antibiotics to administer to the dog. Eighty‐nine dogs (3 [3.3%] intact females, 3 [3.3%] intact males, 41 [46%] spayed females, and 42 [47.2%] castrated males) with a mean age of 10.8 years (SD, 3.2 years) were included in the study (Table 2). In our study, surgical treatment of GBM resulted in a significantly longer MST after initial diagnosis compared to dogs treated with medical management alone or with medical management followed by surgical treatment. As it expands, the mucocele can lead to inflammation, tissue death, or rupture of the gallbladder. The full text of this article hosted at iucr.org is unavailable due to technical difficulties. Abbreviations: FI, female intact; FS, female spayed; MC, male castrated; Med, medically managed group; Med‐Sx, medical then surgical group; MI, male intact; Sx, surgical treatment group. Gallbladder mucoceles (GBM) are characterized by the accumulation of tenacious mucin‐laden bile in the gallbladder, which can result in cholestasis and affect gallbladder wall integrity. Survival analysis was performed and prognostic variables identified and compared between treatment groups. This finding also suggests that early detection of low‐scoring GBM may allow for earlier intervention and improved outcomes. Criteria for suspicion of biliary rupture were not standardized because of the retrospective nature of the study and our desire to more accurately represent factors that may have influenced clinical decision making for each case, but pericholecystic effusion and focal‐to‐diffuse hyperechoic mesentery and loss of continuity of the gallbladder wall were considered suspicious of biliary rupture. A mucocele is an accumulation of thick mucus within the gallbladder. Serum total bilirubin concentration also was dichotomized (≤0.3 versus >0.3) based on prognostic findings of previous studies.4, 5, 9 Each multivariable Cox proportional hazards model included factors for treatment group (medically managed, surgery, medically managed, and then surgery) and each potential prognostic factor 1 at a time and an interaction of treatment group and potential prognostic factor. Successful treatment of cholecystitis and cystic duct occlusion requires cholecystectomy and lavage of the common bile duct. Some patients may require intensive care support before and after surgery. Data collected from medical records included signalment (age, sex, reproductive status, and breed), medical, or surgical treatments performed (cholecystectomy or medical treatment with ursodeoxycholic acid [UDCA] with or without other medications or supplements), and results of clinicopathologic testing (CBC and serum biochemistry). However, it is more likely to be a small part of a complex disease process involving inflammation of the gallbladder wall and changes to the lining of the gallbladder changing the consistency of its secretions. There were 46 (51.6%) dogs in the surgical treatment group (Sx), 33 (37.1%) dogs in the medical treatment group (Med), and 10 (11.2%) dogs that initially underwent medical management with subsequent surgery (Med‐Sx). The results of these tests help the doctors caring for your pet to treat concurrent liver disease and infection.

Its use in cats, dogs, horses, and birds to treat liver and gallbladder conditions is ‘off label’ or ‘extra label’. Pets with an incidental mucocele or “premucocele” on ultrasound should be considered for removal of the gallbladder, known as cholecystectomy. Medical management rarely has been reported and medical and surgical management have not been compared. Serum ALP activity was found to be significantly associated with outcome across all treatment groups in the univariate analysis, but HRs calculated with the multivariate model indicated that patients with increased ALP activity in the surgical group to be at highest risk of mortality. Max Parkanzky, Department of Small Animal Medicine and Surgery, University of Georgia College of Veterinary Medicine, 2200 College Station Road, Athens, GA 30605. Chronic kidney disease alone negatively impacts long‐term prognosis, but also has implications for renal handling of toxins and medications.31 Acute kidney injury occurring secondary to primary disease, such as pigment nephropathy, as can occur because of bilirubinuria, also is possible and may affect short‐ and long‐term prognosis.32 In our study, it is unknown which measures were undertaken for each patient to stabilize and correct fluid deficits before initiation of treatment, which may have contributed to the significance of the serum creatinine and phosphorus concentrations. In the report from MSPCA by Dr. Johnson, it is noted that about 75 percent of dogs with gallbladder mucoceles have an … English| Español span>, Continuing EducationSurgery Summit| Laboratories| Webinars| CE Meetings| Educational Partners, Animal Health TopicsLarge Animal Topics| Small Animal Topics| Surgical Procedures, Members Only JAVMA 224 (10), 1615-1622 PubMed. In our study, increased serum creatinine concentration and hyperphosphatemia were associated with decreased survival regardless of treatment group. The survival probability crosses at approximately 500 days postdiagnosis therefore failing to meet the assumption of proportional hazards. Ultrasonographic appearance of the gallbladder (GBM type) was significantly different among treatment groups with 77 (86.5%) dogs having ultrasound images available for review (Table 4).

Older, small or middle-sized dogs are most commonly affected. A 6-year-old neutered mixed-breed dog had chronic intermittent diarrhea and recurrent otitis; gallbladder mucocele and hypothyroidism were diagnosed. Large Animal Topics Biochemical abnormalities included increased alkaline phosphatase (ALP) activity (n = 70 of 77 [90.9%]), increased alanine aminotransferase activity (57 of 77 [74.0%]), hyperbilirubinemia (39 of 75 [52.0%]), hypoalbuminemia (36 of 75 [48%]), hypercholesterolemia (35 of 74 [47.3%]), ionized hypocalcemia (13 of 28 [46.4%]), hypoproteinemia (18 of 72 [25.0%]), hyponatremia (18 of 74 [24.3%]), hypochloremia (16 of 71 [22.5%]), hyperchloremia (15 of 71 [21.1%]), total hypocalcemia (12 of 64 [18.8%]), increased blood urea nitrogen concentration (14 of 81 [17.3%]), hypernatremia (12 of 74 [16.2%]), hyperglycemia (13 of 82 [15.9%]), hypoglycemia (13 of 82 [15.9%]), hypermagnesemia (9 of 58 [15.5%]), total hypercalcemia (9 of 64 [14.1%]), hypokalemia (10 of 74 [13.5%]), increased serum creatinine concentration (9 of 73 [12.3%]), hyperkalemia (9 of 74 [12.2%]), hyperphosphatemia (7 of 64 [10.9%]), hypomagnesemia (6 of 58 [10.3%]), low serum bicarbonate concentration (6 of 69 [8.7%]), hyperproteinemia (6 of 72 [8.3%]), hypophosphatemia (4 of 64 [6.3%]), high serum bicarbonate concentration (4 of 69 [5.8%]), hypocholesterolemia (3 of 74 [4.1%]), ionized hypercalcemia (1 of 26 [3.6%]), and increased serum albumin concentration (2 of 75 [2.7%]). Potential cases were identified by searching the medical records database. Only then did your veterinary surgeon earn the title of ACVS Diplomate. Overall mortality rates are reported to be between 20–39% for this disease, however, early surgical intervention may significantly reduce mortality rates. The purpose of our study was to investigate the outcomes associated with medical versus surgical management of GBM and to identify clinical, clinicopathologic, and diagnostic imaging variables associated with prognosis and survival. The condition may be inherited in … The etiopathogenesis of GBM in dogs is unclear and likely to be multifactorial. The median follow‐up duration was 39 (range, 0‐1823) days for all dogs, 13.5 (range, 0‐1823) days in the Sx group, 210 (range, 0‐1340) days in the Med group, and 123.5 (range, 22‐1150) days in the Med‐Sx group. It serves as a reservoir for bile, an important liquid made by the liver that aids in lipid (fat) digestion. Patient breed (P = .22), age (P = .32), and GBM type (P = .19) were not significantly different between dogs in the medically managed group and dogs in the surgical group. This finding is similar to that of previous reports of negative prognostic factors associated with biliary surgery in humans and dogs.28-30 The cause of decreased survival associated with decreased renal function is likely multifactorial. Several patients initially were diagnosed with GBM at nearby referring hospitals and GBM was not always confirmed by in‐house ultrasonography, which may have resulted in further variation in diagnostic criteria for GBM in our study. Suspicion of biliary rupture on abdominal ultrasound (AUS) examination was correlated with increased survival in the surgical group (P = .02). Sx group, surgery (median survival time [MST] 1802 days [855‐not reached]); Med group, MedMgmt (MST 1340 days [444‐1340]); Med‐Sx group, MedThenSx (MST 203 days (18‐525). Abdominal drains may be needed to help manage peritonitis. English| Español span>, Surgical Procedures Medical management rarely has been reported and medical and surgical management have not been compared. ACVS Surgery Summit A recent study found significantly lower mortality (2%) in dogs undergoing elective cholecystectomy compared to those undergoing emergency cholecystectomy (22%‐40%).9 Some clients still are reluctant to pursue surgical intervention for a variety of reasons but no studies to date have evaluated the outcomes of medical management for GBM. Learn more. Survival probability based on the 2‐group model starting 14 days postdiagnosis with a gallbladder mucocele (GBM). Survival curves for medical management versus surgical management using proportional hazards analysis crossed at approximately 500 days (Figure 1). If you do not receive an email within 10 minutes, your email address may not be registered, Dogs with gallbladder mucoceles that undergo cholecystectomy and survive the immediate post-operative period have an excellent long-term prognosis . Cox proportional hazards analyses were used to test for effects of age and ultrasonographic GBM type on survival and to calculate hazard ratios (HRs) for treatment groups, before and after 14 days since diagnosis, for age, sex, breed, and GBM type. Gallbladder diseases are common reasons for dogs to be referred to board-certified veterinary internal medicine specialists.
