Background
Transjugular intrahepatic portosystemic shunt (TIPS) procedure has played a vital role in management of portal hypertension. Thus, we aimed to investigate the natural history, long-term clinical outcome, predictors of survival in viral hepatitis related cirrhotic patients post-TIPS.
Method
A total of 704 patients with complete followed-up data were enrolled, and clinical characteristics of patients were collected and analyzed. Kaplan-Meier method was used to calculate survival, and comparisons were made by log rank test. A multivariate analysis of factors influencing survival was carried out using the Cox proportional hazards regression model.
Results
TIPS implatantion significantly decreased portal vein pressure with 9.77 cmH2O reduction, without influencing long-term liver functions. The total incidence rate of major complication post-TIPS, including HE and re-bleeding/bleeding, was 37.9% and 15.5%, respectively. Patients in Child-Pugh C stage revealed higher overt hepatic encephalopathy (HE) occurrence (65.6%), while patients receiving covered, 6 mm in diameter stents indicated notably lower incidence of HE in comparison with other groups (6.4%). The median survival was > 60 months, 27.0 months, and 11.5 months in cirrhotic patients with variceal bleeding, refractory ascites, and both complications, respectively. The cumulative 5-year survival was significantly higher in patients with variceal bleeding (75.6%) in comparison with either that in patients with refractory ascites (12.5%) or that in patients with both complications (1.96%) (P < 0.0001). Covered stents usage, baseline model for end-stage liver disease (MELD) score, and baseline Child-Pugh classification were predictive of survival (P < 0.001). Other variables including age, male gender, and pre-TIPS PVP were not emerged as significant predictors (P > 0.05).
Conclusion
TIPS was an effective and safe therapeutic method for decompression of portal hypertension and for treatment of its complications. Careful selection of patients with minimal liver dysfunction for TIPS implantation was essential for better long-term outcomes.
