OBJECTIVETo assess the safety and clinical efficacy of transjugular intrahepatic portosystemic shunt (TIPS) with various stents for treating patients with cirrhosis and esophageal gastric varices bleeding.

METHODSOne hundred and five patients were stratified according to stent type: bare stent group, covered stent-grafts group, combined stents group. Rates of success, shunt insufficiency, rebleeding, patient survival, and major complications were observed. The shunt insufficiency rate, rebleeding rate, and survival rate were calculated by the life tables method, the Kaplan-Meier analytical curve, and the log-rank test; a p-value less than 0.05 was considered statistically significant.

RESULTSThe overall success rate of all TIPS for treating the esophageal gastric varices bleeding was 100%. The overall shunt insufficiency rates at 6-, 12-and 24-months post-TIPS were 8%, 9% and 16%, rebleeding rates were 2%, 6% and 17%, and survival rates were 100%, 97% and 94%. The shunt insufficiency rate was 26% in the bare stent group, 14% in the covered stent-grafis group, and 5% in the combined stents group (x2=1.00, P=0.61). The rebleeding rate was 33% in the bare stent group, 7% in the covered stent-grafts group, and 3%in the combined stents group (x2=1.69, P=0.43). The survival rate was 92% in the bare stent group, 93% in the covered stent-grafts group, and 100% in the combined stents group (x2=1.91, P=0.39). The shunt insufficiency rates were higher in patients with splenectomy than in those without splenectomy (30% vs.14%; x2=4.15, P=0.04). The intraperitoneal hemorrhage rates in the covered stent-grafis group and the combined stents group were significantly lower than that in the bare stent group (0% vs 0% vs 13%; x2=8.88, P=0.01).

CONCLUSIONSTIPS with an 8 mm stent effectively treated and prevented esophageal gastric varices bleeding in patients with cirrhosis. Intraperitoneal hemorrhaging caused by TIPS was significantly decreased in the covered stent-grafts group and combined stents group,which represented an improvement in safety of this treatment. However, the influence of covered stent-grafis and combined stents towards the clinical efficacy of TIPS needs further study.
