Abstract

Abstract Background Influence of portal vein thrombosis on efficacy of endoscopic variceal banding in patients with cirrhosis or extrahepatic portal vein obstruction has never been evaluated. Aim of the study was to assess influence of thrombosis on rate and time to eradication in cirrhosis and extrahepatic portal vein obstruction undergoing banding, compared to cirrhotic patients without thrombosis. Methods Retrospective analysis of 235 consecutive patients (192 with cirrhosis without thrombosis, 22 cirrhosis and thrombosis and 21 extrahepatic portal vein obstruction) who underwent banding. Banding was performed every 2–3 weeks until eradication; endoscopic follow-up was performed at 1, 3, 6 months, then annually. Results Eradication was achieved in 233 patients. Median time to eradication in cirrhotic patients with portal vein thrombosis vs. cirrhotic patients without thrombosis was 50.9 days (12–440) vs. 43.4 days (13–489.4); log-rank: 0.04; patients with extrahepatic portal vein obstruction vs. cirrhotic patients without thrombosis 63.9 days (31–321.6) vs. 43.4 days (13.0–489.4); log-rank: 0.008. Thrombosis was shown to be the only risk factor for longer time to eradication. Conclusions Portal vein thrombosis per se appears to be the cause of a longer time to achieve eradication of varices but, once eradication is achieved, it does not influence their recurrence.
