What are the blisters on the liver?

The term "blisters in the liver" is a very common term. Medically, it is called liver cyst, which is also a benign cystic disease. This type of cyst will not make people feel uncomfortable, nor will it continue to spread. It is just that during the course of the disease, it may slowly grow larger over time. As long as it is properly cared for, it can recover without surgery.

"Blisters" growing in the liver is a popular term. Medically, it is called "liver cyst", which is a benign disease.

Usually, people with liver cysts do not feel any discomfort. During a physical examination, the doctor may find one or even several blisters through ultrasound.

A few cysts contain clear fluid, like a water balloon, but most cysts, especially smaller ones, do not contain any substance. Under ultrasound, one or more cysts can be seen, the larger of which can be up to 10 cm in diameter, while the smaller ones can be as small as 1 cm in diameter. But no matter the size or number of the cysts, there is generally no discomfort and it will not affect liver function.

There is no definite explanation for how cysts are formed, but it may be related to the many small bile ducts in the liver. There is also a type of liver cyst that is related to genetics, called "multiple liver cysts". New cysts will continue to grow in the patient's liver, and the liver will become larger. The patient can even feel the swollen liver, which sometimes feels a little painful. Almost half of the patients will also have kidney cysts. However, there will be no liver dysfunction and no development of liver cancer.

Cysts will neither affect liver function nor develop into liver cancer, so they usually do not need to be treated. But if it grows really large and makes the patient feel uncomfortable, it can be treated. There is no need for surgery during treatment. Under the guidance of ultrasound, the doctor can insert a thin needle into the cyst, draw out the fluid in the cyst with the thin needle, and then inject pure alcohol to prevent the cyst from growing again.

If the cyst grows very large and the patient feels a lot of pain, surgical treatment can be considered to remove the cyst together with the cyst membrane to relieve the patient's pain.
