A blister on the liver is a liver condition that you normally see called a liver cyst. In the case of liver cysts, if you want to deal with this lesion, the first step is to look at the specific size of the blisters, or cysts, on the liver by doing a CT or ultrasound. Generally, if it is more than 5 cm, an interventional approach can be taken, where a puncture needle is placed into the liver cyst under the guidance of ultrasound or CT, and after extracting the cystic fluid from the liver, a sclerosing agent can be injected into the liver cyst cavity so that the liver cyst can be treated completely. In addition, surgical treatment can also be performed through minimally invasive laparoscopic surgery, during which the liver cyst is decompensated and the large omentum can be inserted into it after the cyst fluid is aspirated, so that the surface of the liver cyst adheres to the omentum and prevents the recurrence of the liver cyst after surgery. Therefore, patients who have liver cysts must go to regular specialized hospitals for detailed examination, systematic treatment for the cause of the disease, and selection of reasonable surgical methods.
