Prevention of Variceal Rebleeding by EUS-guided vs Conventional Endoscopic Therapy in Hepatocellular Carcinoma Patients

Summary

Rebleeding rate is high in hepatocellular carcinoma (HCC) patients with variceal bleeding despite conventional endoscopic therapies for esophageal and gastric varices (EV, GV). Secondary prevention of variceal rebleeding was reported to improve outcomes of HCC patients, but the optimal endoscopic approach is not well defined. In this difficult-to-manage population, variceal rebleeding rates remain substantial after conventional endoscopic therapies. n recent studies by others and our group on direct EUS-guided therapy for varices in cirrhotic patients, high technical success (90 - 100%), low post-treatment rebleeding rate (3 - 11%) and low adverse event rate (\~3%) have been reported for GV treatment by cyanoacrylate glue injection, coiling or a combination of both, and for cyanoacrylate glue injection or coiling of EV refractory to variceal band ligation (VBL). This study aims to compare rebleeding rates after secondary prevention by EUS-guided therapy or conventional endoscopic therapy in HCC patients with recent variceal bleeding.

Eligibility

Inclusion Criteria:

* Consecutive HCC patients age 18 or older with recent (within 4 weeks of the episode) EV or GV bleeding successfully controlled by conventional endoscopic therapies (VBL for EV or glue injection for GV)

Exclusion Criteria:

* Unable to provide written informed consent
* Contraindications for endoscopy due to underlying comorbidities
* HCC patients with non-variceal source of gastrointestinal bleeding
* Refractory coagulopathy (INR\>1.5) or refractory thrombocytopenia (platelets \<50,000) despite blood product transfusion
* Moribund patients from terminal illness
