Abstract
Video 1Case 1 EUS liver biopsy with FNA needle complicated by persistent blood flow within biopsy tract, which is successfully treated with blood patch technique. Case 2 EUS liver biopsy with FNA needle complicated by persistent blood flow within biopsy tract, which is successfully treated with blood patch technique.
Highlights
EUS-guided liver biopsy is emerging as an alternative form of tissue acquisition to percutaneous or interventional radiology–guided liver biopsy
EUS-guided liver biopsy is performed with a 19-gauge FNB needle
While the needle is within the biopsy tract, the FNA stylet is inserted into the needle, pushing out about 25% of the distal needle contents
Summary
EUS-guided liver biopsy is emerging as an alternative form of tissue acquisition to percutaneous or interventional radiology–guided liver biopsy. There are limited endoscopic interventions available to prevent bleeding during liver biopsy. Recent studies have shown efficacy with blood patch pleurodesis for alveolaopleural fistula closure.. Recent studies have shown efficacy with blood patch pleurodesis for alveolaopleural fistula closure.2 With this in mind, we have developed a novel approach to facilitating hemostasis to prevent active bleeding during EUSguided liver biopsy by delivering a blood patch through the FNB needle into the biopsy tract before needle extraction. We have developed a novel approach to facilitating hemostasis to prevent active bleeding during EUSguided liver biopsy by delivering a blood patch through the FNB needle into the biopsy tract before needle extraction This results in cessation of bleeding within the needle tract, thereby preventing post–liver biopsy hemorrhage
