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.
