Salvage transjugular intrahepatic portosystemic shunt in patients with cirrhosis and refractory variceal bleeding: A systematic review with meta‐analysis

BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) may be used as a salvage treatment in patients with cirrhosis and refractory variceal bleeding. AIM: To synthesize the available evidence on the efficacy of TIPS in patients with cirrhosis and refractory variceal bleeding. METHODS: Meta‐analysis of trials evaluating TIPS in patients with cirrhosis and refractory variceal bleeding, including subgroup analysis to assess the impact of recent changes in the management of variceal bleeding (i.e., the use of Polytetrafluoroethylene‐covered TIPS and the availability of pre‐emptive TIPS as a first‐line treatment for acute variceal bleeding). RESULTS: Twenty‐three studies with 1430 patients were included. The pooled estimate rates were 0.33 (95% CI = 0.29–0.37) for death at 1 month–6 weeks, 0.46 (95% CI = 0.40–0.52) for death at 1 year, and 0.09 (95% CI = 0.06–0.11) for death due to rebleeding in the follow‐up. The pooled estimate rates for death at 1 month or 6 weeks were similar in subgroup analyses including studies that did not use covered TIPS or that did not include patients after the pre‐emptive TIPS area compared to the ones that did (pooled estimate rate 0.33 [95% CI = 0.28–0.38] and 0.32 [95% CI = 0.25–0.39], respectively). The pooled estimate rates were 0.16 (95% CI = 0.13–0.18) for rebleeding, 0.25 (95% CI = 0.17–0.36) for occurrence of hepatic encephalopathy, and 0.08 (95% CI = 0.05–0.13) for access to liver transplantation after TIPS insertion. CONCLUSIONS: One third of patients with cirrhosis and refractory variceal bleeding treated with salvage TIPS died within the first 6 weeks. Recent improvements in the management of variceal bleeding did not improve the survival of patients presenting with refractory variceal bleeding.
