Outpatient clinics often see patients with liver cysts and hepatic hemangiomas found on examination. The main reason is that nowadays, ultrasound and B-ultrasound diagnostic technology has become very sensitive, and many small and medium-sized hospitals and health check-up centers have the ability to equip new B-ultrasound machines with high sensitivity, so many lesions smaller than 1 cm or even smaller than 5 mm can be clearly displayed. This is why so many patients are diagnosed with hepatic cysts and hepatic hemangiomas. Therefore, I think it is necessary to write this article to popularize this kind of “patients”. The answer is in the form of questions and answers, and the answers are followed by my explanations. 1. The first and most important question is: Is liver cyst and liver hemangioma important? Is this disease serious? Liver cyst is a benign disease of the liver, and liver hemangioma is also a benign disease of the liver, which means that both diseases do not matter and are not serious. They are not cancerous and do not affect the function of the liver. The risk of rupture is the same as that of a normal liver, which means that only the cysts and hemangiomas growing inside the ruptured liver may rupture – the chance of rupture is very low, and even if they do rupture, they are mostly not life-threatening. Except for huge cysts and hemangiomas larger than 10 cm, they usually do not have any uncomfortable symptoms and do not affect health or daily life. 2. The question that arises is: Is it necessary to go to a big hospital for liver cysts and hemangiomas? If liver cysts and hepatic hemangiomas are found for the first time, it is still necessary to go to a big hospital to confirm the diagnosis. However, some of them need to be distinguished from liver tumors, especially hepatic hemangioma is a solid lesion, and if the patient also has chronic hepatitis, such as hepatitis B and C, it must be distinguished from early liver cancer. In this case, it is usually necessary to go to a large hospital to have another ultrasound to confirm the diagnosis. For elderly patients with chronic hepatitis who still cannot be diagnosed, expensive examinations such as ultrasonography, enhanced CT, MRI, etc., together with blood tests for tumor markers such as AFP, CA19-9, etc., should be performed when necessary. 3. The last question that patients are concerned about is: How to treat liver cysts and hepatic hemangioma? No medication is needed, and no medication can slow down the growth rate of liver cysts and hepatic hemangiomas, and it is impossible to cure them. The only treatment needed is “regular review” to observe the changes in the location and growth rate of the lesions. 4.How often is this “regular review”? If there is no significant change in the size and number of liver cysts and hepatic hemangiomas, they should be reviewed once every six months and once every year if the growth does not exceed 1 to 2 cm in two years. 5.What cases require surgery? There are two types of cases that require surgery: first, huge liver cysts and hepatic hemangiomas with pressure symptoms, usually at least 10 cm will produce pressure symptoms, such as abdominal distension, abdominal pain, and even larger ones will have abdominal bulge. Secondly, liver cysts and hemangiomas in special areas with fast growth rate. In a small number of patients, the lesions grow faster, increasing by 2 to 3 cm per year, and are located near important anatomical parts such as blood vessels and bile ducts, and the risk of surgery increases significantly if they continue to grow and compress these important parts. 6.What are the surgical methods? Liver cysts are usually cured by laparoscopic window decompression, releasing the cystic fluid into the peritoneal cavity and absorbing it through the peritoneum. Some hepatic hemangiomas can be removed through laparoscopic minimally invasive surgery, while others require open surgery. Patients who are too old or have serious heart and lung disease that cannot be operated on can undergo ultrasound intervention, which is not as effective as surgery, but can reduce symptoms.
