Summary

The development of portal hypertension is a vital event in the natural progression of cirrhosis and is associated with severe complications including gastroesophageal varices bleeding. Cirrhotic patients with hemorrhagic shock and/or liver failure caused by variceal bleeding face a mortality of 5-20%.

Hepatic venous pressure gradient (HVPG) is the recommended golden standard for portal pressure assessment globally with favorable consistency and repeatability. Reducing the HVPG to levels of 12mmHg or below is associated with protection of variceal hemorrhage. An HVPG> 16mmHg indicates a higher risk of death and HVPG 20mmHg predicts failure to control bleeding, early rebleeding, and death during acute variceal hemorrhage.

The management of portal hypertension has showed a trend of diversification with the development of medication, endoscopy, radiological intervention and liver transplantation. Although medication and endoscopic therapy have achieved preferable effects and are recommended as standard of care for the prevention of variceal rebleeding, patients with HVPG 16mmHg still have a high risk of treatment failure and a high rate of rebleeding. Recent years, early TIPS is recommended as the first-line therapy for the prevention of rebleeding in cirrhotic patients with HVPG 20mmHg. However, for those with HVPG values between 16 to 20mmHg, there is still lack of strong evidence to demonstrate the best practice for the management.

With the rapid advancement of laparoscopic device and technique, the utility of laparoscopic splenectomy and pericardial devascularization showed less surgical trauma, bleeding and complications while retaining dependable effects compared to traditional open surgery, especially for portal hypertension with hypersplenism. In the study, the investigators aim to conduct a multicenter randomized controlled trial to compare the safety and effectiveness of HVPG-guided (16 to 20mmHg) laparoscopic versus endoscopic therapy for variceal rebleeding in patients with portal hypertension.
