Among extra-GI hepatic causes of chronic diarrhea, which option best represents a chronic hepatopathy with portosystemic shunt?

• A. Acute hepatitis
• B. Chronic hepatopathy with portosystemic shunt
• C. Liver cirrhosis
• D. Fatty liver disease

Answer: (B)

Chronic diarrhea from hepatic disease with a portosystemic shunt occurs when portal blood bypasses the liver, so toxins that would normally be detoxified circulate systemically and can disrupt intestinal function. The key feature is a long-standing liver problem that includes a shunt linking the portal and systemic circulation, which leads to persistent GI signs like diarrhea due to toxin exposure and altered gut physiology. This makes the option describing a chronic hepatopathy with portosystemic shunt the best match for the scenario. Acute hepatitis is not chronic, cirrhosis is a chronic liver disease but doesn’t inherently specify a shunt, and fatty liver disease doesn’t inherently involve a portosystemic shunt.
