Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Efficacy of EUS-guided treatment for varices	Efficacy will be determined by recording recurrent events of hematemesis and/or melena after the EUS-guided procedure. Further confirmation of gastroesophageal variceal hemorrhage will be evaluated by upper gastric endoscopy and lab tests.	6 months
Secondary	Safety of EUS-guided combination therapy in cirrhotic patients with gastroesophageal varices and hypersplenism	Safety will be determined by measure of incidence of adverse events related to EUS-guided procedure within and after 30 days of the procedure.	6 months
Secondary	Efficacy of EUS-guided partial splenic embolization	Efficacy will be measured by rates of successful technique among all performance. Technical success is defined as complete obliteration of the branch of splenic artery and absence of Doppler flow on EUS, and functional success, defined as improved hematologic parameters and the detectable splenic infarction by CT.	6 months
