Nowadays, as people’s living standards improve, more and more people choose to go to the hospital for medical checkups, among which, one kind of disease frequently appears in the medical checkup report, that is, liver cysts. Some friends say that liver cysts “do not matter”, is benign, do not care about it. Some friends say that some people have liver cysts, the body has become worse, and finally had an operation, so liver cysts should not matter? In fact, it is not so absolute, the liver cysts that are “not important” may also become “important”, so let’s see what is “important” and what is “not important”! Let’s see what is “important” and what is “not important”! What kind of liver cysts do not matter? First of all, it is certain that the vast majority of liver cysts are “not important”! Because liver cysts are not tumors. Secondly, for most patients, liver cysts are asymptomatic, and most of them are relatively small. Therefore, for small and asymptomatic liver cysts, they do not need special treatment and can be said to be okay, but they have to be followed up regularly, and it is good to do ultrasound 1-2 times a year, which is economical and without radiation. What kind of liver cysts are important? The term “critical” means that it needs to be taken seriously and actively treated, not left to chance. In the following cases, active treatment of liver cysts should be considered. 1. Liver cysts that are large or cause compression symptoms. There is no absolute data on how much larger they must be treated, but generally treatment is recommended for diameters over 5 cm. Of course it is not limited to this size, if it causes compression symptoms, such as compression of stomach, duodenum and colon, it may cause symptoms such as postprandial fullness, loss of appetite, nausea and vomiting, and at the edge of the liver it may cause epigastric swelling discomfort, vague pain or mild dull pain, even the liver cyst adjacent to the liver gate may cause mild jaundice by compressing the hepatic duct or common bile duct. Liver cysts with the above symptoms, regardless of their size, are recommended to be treated actively. 2. Secondary infection of liver cysts: In some cases, liver cysts can cause secondary infection, which can lead to pain in the liver area, fever and elevated blood leukocytes, etc. This needs to be treated. 3.Cyst secondary bleeding: A few liver cysts can have spontaneous rupture of blood vessels in the cyst wall, leading to bleeding inside the cyst. Some patients do not have obvious symptoms, but some patients feel severe pain in the liver area. These patients should be treated actively. 4. Cyst torsion: A liver cyst with a tipped edge can produce severe pain if it is twisted, and this should be treated urgently. How is that liver cyst treated? In the past, liver cysts required surgical open-heart treatment, which is traumatic and risky, and it is not worth paying so much for liver cysts, so some people are not willing to go for treatment even if they have some symptoms. Now the treatment of liver cysts is very simple! There is no need to operate at all, and as long as no torsion occurs, minimally invasive treatment can be performed: a very thin needle or tube is threaded into the liver cyst to drain the cyst fluid, and then a drug is injected into the cyst through the needle or tube. The drug can destroy the wall of the liver cyst, and the liver cyst will slowly shrink and become smaller or even disappear. As for the wound, a band-aid is put on the puncture port after the surgery. This is a relatively simple and mature minor surgery, no need for surgery, most hospitals interventional department can be completed, and very little trauma, very low cost, excellent results, friends with “critical” liver cysts can rest assured to actively go to treatment.
