The Child-Pugh classification of liver function, which takes into account the classification of liver function reserve function in patients with cirrhosis, is divided into A, B and C grades for patients with cirrhosis. The Child-Pugh classification of liver function includes biochemical indicators, bilirubin level and TT level of coagulation function, which is the number of seconds of prothrombin time extension. The presence or absence of hepatic encephalopathy, the presence or absence of peritoneal fluid, and the albumin level in the patient’s blood are also used as criteria for liver function. For patients with Child-Pugh classification, a score of 5-6 is graded as grade A; a score of 7-9 is graded as grade B; and a score of 10 or more is considered grade C. For patients with grade A liver function, if the patient has hypersplenism and upper gastrointestinal bleeding symptoms, it is mostly considered to be the manifestation of portal hypertension in cirrhosis, and the patient can actively consider surgical treatment. For patients with grade B or C liver function, patients need to actively consider liver preservation therapy and symptomatic treatment, and then consider surgical treatment when liver function is restored to grade A.
