Abstract
BACKGROUND
Spontaneous portosystemic shunt (SPSS) other than esophago-gastric varices is one of the consequences of cirrhosis-induced portal hypertension (PHT), but its role is not fully understood. Therefore, we conducted a systematic review and meta-analysis to determine the prevalence and clinical characteristics of SPSS (excluding esophago-gastric varices) and its impact on mortality in patients with cirrhosis.
METHODS
Eligible studies were identified from MedLine, PubMed, Embase, Web of Science, and Cochrane Library between Jan 1, 1980 and Sep 30, 2022. Outcome indicators were SPSS prevalence, liver function, decompensated events, and overall survival (OS).
RESULTS
Totally, 2015 studies were reviewed, of which 19 studies recruiting 6884 patients were included. On pooled analysis, the prevalence of SPSS was 34.2% (26.6%∼42.1%). SPSS patients had significantly higher Child-Pugh scores and grades and Model for End-stage Liver Disease scores (all P<0.05). Moreover, SPSS patients experienced a higher incidence of decompensated events, including hepatic encephalopathy, portal vein thrombosis, and hepatorenal syndrome (all P<0.05). Additionally, SPSS patients had significantly shorter OS than the non-SPSS group (P<0.05).
CONCLUSIONS
In patients with cirrhosis, SPSS outside the esophago-gastric region is common, characterized by severe impairment of liver function, high rates of decompensated events, including HE, PVT, and hepatorenal syndrome, as well as a high mortality rate.
