Abstract
BACKGROUND AND AIM: The aim of this study was to compare the feasibility and safety of both balloon-occluded retrograde transvenous obliteration (BRTO) versus transjugular intrahepatic portosystemic shunt (TIPS) for treatment of gastric varices due to portal hypertension through the method of meta analysis.
METHODS: PubMed, Embase and Cochrane Library were searched for both randomized controlled trials (RCTs) and cohort studies concerning BRTO compared with TIPS in the treatment of gastric varices from their inception to April 26, 2015. The Cochrane network RevMan 5.3 software was used for statistic analysis. The primary markers which need to be evaluated contains technical success rate, hemostasis rate, incidence rate of post-operative rebleeding, incidence rate of hepatic encephalopathy and postoperative procedure-related complication. Study-specific odds ratios (ORs) were combined to calculate pooled value by using random-effect models.
RESULTS: Five original studies were included in total. Meta-analysis showed that BRTO and TIPS had no difference in aspects of technical success rate (OR, 0.19; 95% CI, 0.03-1.08; P=0.06), hemostasis rate (OR, 3.41; 95% CI, 0.33-35.40; P=0.30) and incidence rate of postoperative procedure-related complication (OR, 1.98; 95% CI, 0.44-8.84; P=0.37). However, BRTO had a lower incidence rate of post-operative rebleeding (OR, 0.27; 95% CI, 0.09-0.81; P=0.02) and lower incidence rate of post-operative encephalopathy(OR, 0.05; 95% CI, 0.02-0.13; P<0.000 01).
CONCLUSIONS: BRTO was a technically feasible as well as secure method for the treatment of gastric varices originated from portal hypertension. It may have the potential to be an alterative shunt approach of TIPS, when suitable patients selected.
