Early transjugular intrahepatic portosystemic shunt for acute variceal bleeding: a systematic review and meta-analysis

Abstract

Objectives The alleged benefit of early placement of transjugular intrahepatic portosystemic shunt (TIPS) in patients with cirrhosis and acute variceal bleeding (AVB) remains controversial. This meta-analysis was conducted to evaluate the therapeutic effect of early TIPS on cirrhotic patients with AVB. Methods MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases were searched for relevant literatures. Data from included studies were extracted, and random-effects meta-analyses were performed. Results Three randomized control trials and six observational studies involving 2878 participants were included. Compared with those undergoing standard treatment, patients undergoing early TIPS had a significantly lower all-cause mortality (RR, 0.64; 95% CI, 0.52–0.79). Furthermore, early TIPS was associated with a significantly reduced incidence of failure to control bleeding (RR, 0.15; 95% CI, 0.07–0.29) and rebleeding (RR, 0.40; 95% CI, 0.23–0.71), without increasing the risk of hepatic encephalopathy (RR, 1.13; 95% CI, 0.92–1.38). In a stratification analysis based on Child-Pugh classification, the survival benefit was observed in Child-Pugh B patients with active bleeding (RR, 0.53; 95% CI, 0.31–0.93) and Child-Pugh C patients (RR 0.55, 95% CI, 0.37–0.82), but not in low-risk patients (Child-Pugh A and Child-Pugh B without active bleeding) (RR, 0.93; 95% CI, 0.55–1.57). Conclusion Early TIPS is a feasible therapeutic option for cirrhotic patients with AVB, especially benefiting high-risk patients in terms of improved survival. Given the current low utilization rate in clinical practice, this study favors the placement of early TIPS in a wider range of patients with cirrhosis and AVB, especially high-risk patients. Key Points • Early TIPS is associated with improved survival in high-risk patients (Child-Pugh B plus active bleeding at endoscopy or Child-Pugh C 10–13) with cirrhosis and acute variceal bleeding. • Current utilization rate of early TIPS is low in clinical practice.
