EUS-guided PSE in Combination With EUS-guided Treatment of Varices for Patients With Portal Hypertension

EUS-guided Partial Splenic Embolization in Combination With EUS-guided Treatment of Varices for Patients With Portal Hypertension

This study aims to evaluate the efficiency of EUS-guided combination therapy (EUS-guided PSE + EUS-guided treatment of varices) to EUS-guided treatment of varices alone in cirrhotic patients with portal hypertension who have developed gastroesophageal variceal hemorrhage and accompanied with hypersplenism.

Partial splenic embolization (PSE) was developed in the purpose of managing two common complications of portal hypertension including variceal bleeding and hypersplenism. The procedure is normally performed by clinicians engaged in interventional radiology via a transcatheter embolization method as the successful embolization of the selected splenic arteries results in devascularization of a focal lesion followed by splenic infarction and subsequently reducing the splenic contribution to the portal blood flow. Our previous case study suggests implanting coil in a branch of splenic artery under the endoscopic ultrasound (EUS) -guidance followed by the glue injection was an alternative PSE procedure to control hypersplenism. Recent advance has also heightened the therapeutic aspect of EUS in managing varices. We have established the novel approach to manage varices and hypersplenism at the same time by combining EUS-guided PSE and EUS-guided treatment of varices. This study aims to evaluate the efficiency of EUS-guided combination therapy (EUS-guided PSE + EUS-guided treatment of varices) to EUS-guided treatment of varices alone in cirrhotic patients with portal hypertension who have developed gastroesophageal variceal hemorrhage and accompanied with hypersplenism.
