Portal vein thrombosis (PVT) can lead to a further increase in portal venous pressure and increase the risk of rebleeding. Whether patients with acute esophagogastric variceal bleeding with occlusive PVT benefit from preemptive TIPS is still controversial. The present study is directed at comparing the outcome of patients with acute variceal bleeding with occlusive PVT treated by standard therapy (vasoactive drugs + endoscopic variceal ligation) with or without preemptive TIPS (performed during the first 1-3 days after endoscopic procedure). The primary outcome is survival free of variceal rebleeding at 6 weeks from inclusion.
Portal vein thrombosis (PVT) is a common complication in patients with cirrhosis, and the cumulative incidence of PVT is 4.6%, 8.2%, and 10.7% at 1 year, 3 years, and 5 years, respectively. PVT can lead to a further increase in portal venous pressure and increase the risk of rebleeding. According to Baveno VII, PVT can be classified according to the degree of occlusion of the portal trunk as complete occlusion (no continuous luminal structure), partial occlusion (≥50% thrombus obstruction of the lumen), mild occlusion (\<50% thrombus obstruction of the lumen), or spongiotic degeneration (a large number of collateral vessels of the portal vein, with no visualization of the main portal vein). The results of a recent observational study suggested that patients with severe PVT with ≥50% thrombotic luminal obstruction had higher 6-week rebleeding rates (8.8% vs. 3.8%) and 1-year rebleeding rates (29.4% vs. 21.4%) after acute variceal bleeding. Our previous clinical study showed that patients with cirrhotic PVT treated with TIPS had lower rebleeding rates and significantly higher rates of portal vein recanalization, and it was inferred that patients with acute esophagogastric variceal bleeding with severe PVT might benefit from preemptive TIPS. Therefore, we propose to conduct a multicentre randomized controlled trial to enroll patients with acute esophagogastric variceal bleeding with occlusive PVT to compare the preemptive TIPS with the standardized therapy. The outcomes are rates of mortality, rebleeding, and complications.

Exclusion Criteria:
Standard treatment to achieve initial hemostasis: vasoactive drugs (somatostatin or terlipressin) + endoscopic hemostasis according to the center protocol. Standard combined endoscopic and pharmacological therapy as secondary prophylaxis (carvedilol + repeated endoscopic variceal ligation until the eradication of the esophageal varices).
Procedure: standard second prophylaxis
Standard treatment to achieve initial hemostasis: vasoactive drugs (somatostatin or terlipressin) + endoscopic hemostasis according to the center protocol. Performance of TIPS in the first 72 hours following initial endoscopic hemostasis.
Procedure: preemptive TIPS
The TIPS procedure should be performed within 72 hours after the initial endoscopic examination or treatment. An 8 mm Viatorr stent will be used for TIPS establishment. The aim will be to reduce the portal pressure gradient below 12 mm Hg. Embolization, either with coils or glue, can be performed, if it is felt necessary, especially in patients where portography shows the filling of large portosystemic collaterals feeding the varices. After TIPS, anticoagulation will not be used as a rule but is allowed if the attending physician thinks that it is warranted.
Also known as: early TIPS
Patients will receive vasoactive drugs up to 5 days; then a non-selective beta-blocker (carvedilol) will be started with an initial dose of 6.25 mg, the dose of propranolol will be increased to 12.5 mg. The second elective session of endoscopic band ligation will be performed within the first 28 days after the initial endoscopic treatment. The following sessions will be performed at 28 +/- 3 days intervals until variceal eradication. Once eradication is achieved, endoscopic monitoring will be performed every 6 months. If varices reappear, new band ligation will be performed.
Also known as: endoscopy plus drug treatment
6-week mortality
The rate of mortality during the first 6 weeks after inclusion in the study.
Time frame: 6 weeks
5-day treatment failure
Incidence of cases requiring adjustment of treatment strategy within 5 days of initial standardised treatment: vomiting of blood or drainage of ≥100 ml of fresh blood from a gastric tube after 2 hours of treatment, hypovolemic shock, drop in haemoglobin of 30 g/L or more within 24 hours without transfusion.
Time frame: 5 days
1-year mortality
