Abstract
Transjugular intrahepatic portosystemic shunt (TIPS) is a useful approach in managing complications caused by severe portal hypertension (PH) in adults. In children, TIPS is technically challenging, and previous studies of TIPS in children have yielded inconsistent results. This study aimed to elucidate the feasibility and clinical effectiveness of TIPS in pediatric and adolescent patients. This meta-analysis study identified relevant publications through medical databases. The primary outcomes included technical success, hemodynamic success, and clinical success. The secondary outcomes were primary patency rate, shunt revision rate, and secondary patency rate. A total of 286 patients representing 13 studies were eligible for analysis. The pooled rates of technical success, hemodynamic success, and clinical success were 95% (95% CI 88-99), 89% (95% CI 81-95), and 93% (95% CI 86-98), respectively. The portosystemic gradient decreased from 21.5mmHg before TIPS to 8.3mmHg after TIPS. The pooled estimates of primary patency rate, shunt revision rate, and secondary patency rate were 84% (95% CI 72-94), 35% (95% CI 21-51), and 100% (95% CI 92-100), respectively. Study results suggest that TIPS may be feasible and effective in children with PH of various etiologies as for long-term management.
