Optimizing Endoscopic and Interventional Treatment for Portal Hypertensive Bleeding

This study aims to evaluate the impact of high-risk factors-such as elevated portal venous pressure, concurrent large extra-luminal vessels, portal vein thrombosis, and prominent portosystemic shunts-on the efficacy of endoscopic therapy. By comparing with interventional treatment, the goal is to optimize the clinical management protocol for esophageal and gastric varices, enhance the therapeutic outcomes of portal hypertension-related esophageal and gastric varices, and improve patient prognosis.

Pre-emptive RTO for An Early Detected Gastric Varices in CT/MR Angiogram Trial

A number of treatment modalities are currently in use for gastric variceal bleeding (GVB). Balloon-occluded, plug-assisted, and coil-assisted retrograde transvenous obliteration (RTO) procedures are described in the literature as treatments for GVB after a bleeding episode occurs. Preliminary data suggests that prophylactic treatment of gastric varices may improve patient outcomes compared to conservative management. This study aims to compare pre-emptive treatment of gastric varices with current recommended medical management in a randomized prospective study design. Eligible patients will be randomized to receive RTO or to continue conservative management. Patients will be followed for up to 2 years for comparison of clinical outcomes, including episodes of gastric variceal bleeding, overall survival and transplant-free survival, complications, and secondary interventions.
