The diagnosis of portal cirrhosis is that when the patient checks the ultrasound, it will suggest hypodensity of the liver and there will be tortuous as well as dilated liver ducts. Some patients may have wavy changes in the liver envelope, and in patients who have been there for a long time, they may have an enlarged spleen, all of which are indirect manifestations of cirrhosis on ultrasound. In such cases, patients need to be further investigated for underlying liver disease. The patient may have viral hepatitis or autoimmune hepatitis, or if the patient has been drinking alcohol and taking medications for a long time, all of which can cause cirrhosis. Patients need further blood tests for hepatitis B triple system and hepatitis C antibodies to see if they have viral hepatitis and, if necessary, autoimmune related tests. If the patient has a combination of viral hepatitis, it is necessary to check the hepatitis B DNA and hepatitis C RNA, if necessary, and to actively consider antiviral therapy if the virus is replicating and the liver function is impaired. If the patient is in the decompensated stage of cirrhosis, has an enlarged spleen and esophageal varices in the fundus of the stomach, and has a history of upper gastrointestinal bleeding, antiviral treatment should be actively considered. In this case, we should actively consider performing portal oddissection surgery.
