In the outpatient clinic, there are often patients who anxiously ask the doctor: I have a growth in my liver, is it dangerous? Should I take medicine? Should I have an operation? The doctor then asks what is growing, some answer liver cysts, some answer hemangioma, some answer calcified spots, suspected hepatobiliary stones. Because of the growth in the liver, the patient is particularly worried, looking around for medicine, and even find some local remedies to eat, there are also many people ask for quick surgery to avoid malignant changes. These three kinds of lesions are basically benign lesions, most do not need to deal with, patients should not “fuss”, rashly deal with, pay a heavy price. The vast majority of people regular review on the liver cysts, hemangiomas, plaques in the clinic is very common, but patients tend to get a physical examination report on the scared, thinking that malignant changes or rupture, they are eager to find medicine to eat, or simply all things, the results in turn caused unnecessary damage. Liver cysts are actually blisters, and unless they are very large, they generally do not need to be treated. And from a clinical point of view, hemangiomas rarely rupture and are rarely cancerous. As for calcified spots, they are usually scarring formed by localized degeneration and necrosis of liver cells, just like moles and spots on the face, which are very common. Therefore, most of the patients do not need to be nervous, and can be rechecked every six months to a year, with a simple liver and gallbladder ultrasound, and CT if possible. What should be dealt with at an early stage? As these are benign lesions, the general principle is that they should not be treated at the cost of too much damage. However, in some cases, early intervention is possible, with the aim of removing benign lesions with little damage to the patient, and at the same time, relieving the patient’s anxiety and worry. Liver cysts: The liver cysts referred to here are mostly congenital in origin, also known as true cysts, and account for about 90% of all liver cysts. The vast majority of asymptomatic small cysts do not need to be dealt with, such as more than 5 centimeters, swelling and pain discomfort or stomach feel cystic mass, need to be dealt with in a timely manner. 1, for small liver cysts, ultrasound-guided puncture and fluid extraction, or play some pure alcohol into the destruction of the mucosa, so that the cysts adhere to the closure; 2, for large cysts using the “window surgery”, that is, laparoscopy will be spherical cysts to open a mouth, so that the liquid flow into the abdominal cavity, the water will be absorbed. 3, larger cysts, such as half of the liver, or multi-compartmental cysts, such as honeycomb cysts, should be surgically removed. 4, particularly serious polycystic cysts, the whole liver like a vesicle, for such patients, if the liver function is normal, usually no way to deal with, but liver failure, the only way can only replace the liver. Very few polycystic cysts will become malignant. Hemangioma: The most common clinical condition is cavernous hemangioma. Smaller hemangiomas also require no treatment. 1, more than 5 centimeters, located in the edge of the liver, superficial hemangioma, can use laparoscopic minimally invasive surgery. 2. For hemangiomas less than 5 centimeters that are deeply located, interventional ablation is usually used to burn it off. 3. For hemangiomas over 10 centimeters that compress and deform the liver and progress rapidly, open surgery is required. For hemangiomas that do not have any compression symptoms, the liver is not affected and there is no change for a long time, even if the hemangioma is large, generally do not advocate open surgery, and can be regularly reviewed. It is worth noting that a small number of liver cancers are sometimes difficult to be distinguished from hemangiomas on ultrasound or CT, which need to be supplemented with other professional examinations and combined with the patient’s clinical characteristics by experienced hepatobiliary surgeons, so as to avoid major omissions. Calcified plaque: Ultrasound looks basically the same as the acoustic features of liver and gallstones, which is easy to mislead, and CT diagnosis is recommended for the most clarity. This type of plaque generally does not require treatment and can be reviewed periodically. However, patients over 40 years of age with underlying diseases such as cirrhosis, hepatic bile duct stones, hepatic fibrosis, hepatitis B, hepatitis C and other underlying diseases should be more vigilant because a very small number of patients with hepatic and biliary tract tumors may have calcified plaques as a precursor. Points for prevention: 1. For large hemangiomas located superficially, if no surgery is done, avoid strenuous collision sports in normal times; 2. After surgery or treatment, regular rechecks should be made; 3. For dangerous hepatic cysts, hemangiomas, and calcified plaques, the earlier they are treated, the better; 4. Diagnosis and treatment should be made by consulting a professional hepatobiliary surgeon in a regular hospital to find the most suitable method.
