Perihepatic fluid but normal liver function needs to be treated for the cause. If the exudate is caused by cholecystitis, etc., ursodeoxycholic acid, etc., can be used to promote bile excretion. If the fluid is caused by hypoproteinemia, it can be treated with protein supplementation. Inflammatory exudate around the liver may occur in cholecystitis, etc., but liver function is normal. Ursodeoxycholic acid and dehydrocholic acid tablets, etc., can be taken for treatment to promote bile excretion so as not to aggravate the condition and affect liver function. Hypoproteinemia, heart failure, etc. may also appear around the liver with the presence of tissue fluid, and there is no liver function abnormality without liver cell damage. In this case, protein can be supplemented, and diuresis can be promoted with torasemide, etc. to reduce the accumulation of tissue fluid. Perihepatic fluid accumulation but normal liver function may also be caused by other reasons, which should be promptly identified under the guidance of the doctor and timely treatment, so as not to delay the condition.
