Purpose: Biopsy success is driven by target visualization and device placement, the latter of which can be influenced by challenging anatomic locations, target mobility secondary to respirations, and non-rigid deformity as a function of mechanical compression during device placement. The purpose of this study is to assess the early clinical experience of a single center, large academic institution with multiple operators performing hands-free percutaneous biopsies using the XACT ACE Robotic System (XACT Robotics, Ltd., Caesarea, Israel), an FDA-cleared novel device that combines imaging-based procedural planning with robotic navigation and non-linear steering capabilities.
Material and Methods: 17 percutaneous biopsies were performed at our institution using the XACT ACE Robotic System between 8/29/22 and 9/21/22. We report (1) overall technical success as defined by achieving pre-procedurally planned target placement, and (2) accuracy of biopsy needle tip-to-target distance as a function of target distance.
Results: Of the 17 biopsy targets, varied anatomical targets included: lung (4), liver (3), retroperitoneal lymph nodes (2), retroperitoneal abdominal lesions (2), renal lesions (2), spleen (1), and pelvic lesion (1). Two cases were converted from robotic to manual approach. Thus, we report 88% (15/17) technical success rate. 11 cases incorporated recorded pre-procedural target and overall average tip-to-target distance was 3.1 mm. No association between target accuracy as a consequence of target distance.
Conclusions: We report integration of the XACT ACE Robotic System into the clinical workflow of a large academic Interventional Radiology practice with successful initial technical outcomes.
