Many people are found to have liver cysts during a physical examination. So, what kind of disease is a liver cyst? What should be done about it? Liver cysts are a relatively common benign disease of the liver and can generally be divided into parasitic cysts and non-parasitic cysts. The former is caused by parasites, such as cysticercosis in pastoral areas, and the liver cysts we often refer to are the latter, i.e. non-parasitic cysts, which can be subdivided into congenital liver cysts and acquired liver cysts, most of the liver cysts found clinically are congenital and can be only one or multiple, multiple cysts of the catcher are also called congenital polycystic liver, often accompanied by polycystic disease of the kidneys or other organs. Small hepatic cysts are usually those less than 4 cm in diameter, usually without clinical symptoms and often found incidentally during ultrasound or CT examinations. In most cases, they can “live peacefully” with the patient for the rest of his or her life, so there is no cause for concern. Large hepatic cysts with symptoms often present as abdominal distension, right upper abdominal distension or vague pain, cysts on the surface or large palpable masses, fever, chills, swelling and pain when the cyst is combined with bacterial infection, and occasionally jaundice. Liver cyst is a benign disease, but it should not be taken lightly when cystic lesions are found in the liver. When liver cysts are found on physical examination, one should actively seek medical consultation and further examination under the guidance of a specialist to exclude the possibility of liver cancer, and attention should be paid to differentiate the lesions from liver abscess, liver cystic adenoma, cystic metastases, liver encapsulated cysts, etc. to clarify the diagnosis. Once diagnosed as liver cyst, most patients should be observed regularly for a period of time, and if there is no dynamic change in the lesion, the diagnosis of liver cyst will be clearer and more reassuring. Congenital liver cysts with slow growth, less than or equal to 4 cm without symptoms, may not require special treatment. If the cysts are particularly huge or are found to be significantly enlarged by regular observation, or if symptoms such as abdominal distension, fever, chills and jaundice appear, they should be treated promptly, and the treatment methods include: 1. Neither Chinese medicine nor western medicine can make the cyst disappear or shrink.
