Using transjugular intrahepatic portosystemic shunt as the first-line therapy in secondary prophylaxis of variceal hemorrhage.

BACKGROUND AND AIM

This study aims to evaluate and compare the survival and other portal hypertension-related complications of patients with portal pressure gradient (PPG) ≥ 25 mmHg using transjugular intrahepatic portosystemic shunt (TIPS) as the first-line and second-line therapies in secondary prophylaxis of variceal hemorrhage.

METHODS

Fifty patients diagnosed with liver cirrhosis were enrolled in this retrospective study, with 35 of whom received TIPS as the first-line therapy in secondary prophylaxis of variceal hemorrhage and 15 of whom as second-line treatment. We observed and analyzed the survival, occurrence of variceal rebleeding and hepatic encephalopathy (HE) of patients in the two groups during the follow up.

RESULTS

The technical success rate was 100%. In a median follow-up time of 12 (1-37) and 15 (2-27) months, respectively, significant statistical difference was observed between the first-line group and the second-line group concerning cumulative survival rate (94.3% vs 66.7%, log-rank P = 0.01). But that was not the case when it comes to the cumulative rate of variceal rebleeding (8.6% vs 26.7%, log-rank P = 0.164) and HE (22.9% vs 20.0%, log-rank P = 0.793). And multivariate analysis indicated that group assignment (hazard ratio = 8.250, 95% confidence interval = 1.383-49.213, P = 0.021) was the only predictor of survival. Interestingly, we found that spleen diameter (hazard ratio = 0.578, 95% confidence interval = 0.393-0.849, P = 0.005) could be regarded as independent predictor of the occurrence of HE.

CONCLUSIONS

For patients with PPG ≥ 25 mmHg who have recovered from an episode of acute esophageal variceal hemorrhage, utilizing TIPS as the first-line therapy to prevent rebleeding is demonstrated effective in improving the survival and therefore should be recommended to a wider range of clinical practice.
