Background:~Percutaneous biopsy for hepatic masses has a potential risk of bleeding and peritoneal tumor seeding.~A new device for biopsy track ablation has been invented to reduce the risk of bleeding and peritoneal tumor seeding.~Method:~Routine percutaneous biopsy for hepatic masses is performed.~Immediate after obtaining tissue, biopsy needle track is ablated with a new biopsy tract ablator.~Immediate (with ultrasound) and 24 hours (with CT scan) after procedure, occurrence of complications is evaluated.
The purpose of this study is to evaluate the effectiveness and safety of a new biopsy track ablation device for liver biopsy.
