Diseases of the Liver and Gallbladder

2.2K
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Hepatic Portal System01:21

Hepatic Portal System

7.1K
The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...

Summary
This summary is machine-generated.

Hepatobiliary neoplasia in older pets often presents with vague signs and elevated liver enzymes. Surgical removal of large liver tumors can lead to good outcomes and long survival for dogs and cats.

Area of Science:

  • Veterinary Medicine
  • Oncology
  • Diagnostic Imaging

Background:

  • Hepatobiliary neoplasia is uncommon in older companion animals.
  • Clinical signs are often nonspecific, making diagnosis challenging.
  • Elevated liver enzymes on serum biochemistry may indicate liver disease.

Purpose of the Study:

  • To review the diagnosis and treatment of hepatobiliary neoplasia in companion animals.
  • To highlight the role of diagnostic imaging and fine needle aspiration.
  • To discuss the prognosis for animals with liver tumors.

Main Methods:

  • Review of clinical cases of hepatobiliary neoplasia in older cats and dogs.
  • Correlation of clinical signs, biochemical data, and imaging findings.
  • Evaluation of treatment outcomes following liver lobectomy.
  • Histopathological analysis of tumor types and staging.

Main Results:

  • Nonspecific clinical signs and elevated liver enzymes are common.
  • Ultrasound imaging is crucial for characterizing liver lesions and guiding biopsies.
  • Liver lobectomy is the primary treatment for massive liver tumors.
  • Prognosis is favorable for cats and dogs with massive hepatocellular tumors, showing prolonged survival and low recurrence.

Conclusions:

  • Early diagnosis and appropriate treatment are essential for managing hepatobiliary neoplasia.
  • Surgical intervention, such as liver lobectomy, can offer good to excellent prognoses for specific tumor types.
  • Further research into the etiology and optimal management strategies for these tumors is warranted.
