To analyze the diagnostic value of platelet-albumin-bilirubin(PALBI)score in liver cirrhosis complicated with upper gastrointestinal bleeding and the severity of the disease.

One hundred and fifty patients with liver cirrhosis treated in Hainan Cancer Hospital from January 2020 to December 2022 were selected and divided into bleeding group and non-bleeding group, with 75 cases in each group.According to the severity of the disease, the bleeding group was divided into mild bleeding group, moderate bleeding group and severe bleeding group, with 25 cases in each group.Child-Pugh grade, PALBI score and shock index of patients with bleeding were calculated.Spearman correlation test was used to analyze the correlations between PALBI score and Child-Pugh grade and shock index.The receiver operating characteristic(ROC)curve was used to analyze the value of PALBI score in the diagnosis of liver cirrhosis complicated with upper gastrointestinal bleeding and the severity of the disease.

In patients with liver cirrhosis, the PALBI score in the bleeding group was significantly higher than that in the non-bleeding group(P<0.01). The PALBI score in the severe bleeding group was significantly higher than that in the moderate bleeding group(P<0.01), and the PALBI score in the moderate bleeding group was significantly higher than that in the mild bleeding group(P<0.01). PALBI score was positively correlated with Child-Pugh grade and shock index(P<0.05). The area under the ROC curve of liver cirrhosis with upper gastrointestinal bleeding predicted by PALBI score was 0.802, the area under the ROC curve of mild and moderate bleeding was 0.907, and the area under the ROC curve of moderate and severe bleeding was 0.826.

PALBI score is effective in predicting upper gastrointestinal bleeding and diagnosing the severity of upper gastrointestinal bleeding in patients with liver cirrhosis.
