Transjugular intrahepatic portosystemic shunt and splenectomy are more effective than endoscopic therapy for recurrent variceal bleeding in patients with idiopathic noncirrhotic portal hypertension.

ABSTRACT

BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS), splenectomy plus esophagogastric devascularization (SED) and endoscopic therapy + non-selective ß-blockers (ET + NSBB) are widely applied in secondary prevention of recurrent gastroesophageal variceal bleeding in patients with liver cirrhosis. These different treatments, however, have not been compared in patients with idiopathic non-cirrhotic portal hypertension (INCPH). AIM: To compare the outcomes of TIPS, SED and ET + NSBB in the control of variceal rebleeding in patients with INCPH. METHODS: This retrospective study recruited patients from six centers across China. Demographic characteristics, baseline profiles and follow-up clinical outcomes were collected. Post-procedural clinical outcomes, including incidence of rebleeding, hepatic encephalopathy (HE), portal vein thrombosis (PVT) and mortality rates, were compared in the different groups. RESULTS: In total, 81 patients were recruited, with 28 receiving TIPS, 26 SED, and 27 ET + NSBB. No significant differences in demographic and baseline characteristics were found among these three groups before the procedures. After treatment, blood ammonia was significantly higher in the TIPS group; hemoglobin level and platelet count were significantly higher in the SED group (P < 0.01). Rebleeding rate was significantly higher in the ET + NSBB group (P < 0.01). Mortality was 3.6%, 3.8% and 14.8% in the TIPS, SED and ET + NSBB groups, respectively, with no significant differences (P = 0.082). Logistic regression analysis showed that mortality was significantly correlated with rebleeding, HE, portal thrombosis and superior mesenteric vein thrombosis (P < 0.05). CONCLUSION: In patients with INCPH, TIPS and SED were more effective in controlling rebleeding than ET + NSBB, but survival rates were not significantly different among the three groups. Mortality was significantly correlated with rebleeding, HE and PVT.
