This prospective study evaluated the feasibility and safety of percutaneous computed tomography (CT)-guided lung biopsies using a table-mounted robotic system with steering capabilities.
Materials and methods:
The study included 7 patients (5/2 male/female; mean age 73±6.65 years). The biopsy procedure involved robotic navigation, manual insertion of a biopsy introducer needle through the robotic arm followed by manual acquisition of specimens using a biopsy needle which was coaxially inserted. Evaluated lesion characteristics included mean diameter (25.57±9.81mm) as well as distance from pleural surface (18.28±12.27mm). Like prior studies feasibility was defined as the distance of ≤ 10 mm between needle tip after insertion and the nearest lesion edge on the CT scan images. Evaluated parameters included accuracy of needle placement, trajectory length, procedure duration, number of acquired computed tomography scans robot-related troubles as well as adverse events.
Results:
Biopsy needle insertion was feasible in all cases (100% technical success rate). The mean diameter of target lesion was 25.57±9.81mm whilst the distance from pleural surface was 18.28±12.27mm. The median trajectory length was 47.14±22.69 mm. Median scan number was 4 and the median time from the first to final scan was 18±5.06 minutes. Neither robot-related troubles nor adverse events occurred. Pathological diagnosis was possible in all 7 cases (100% diagnostic yield).
Conclusion:
Percutaneous computed tomography-guided lung biopsy using a table-mounted robotic system was feasible and demonstrated high technical success, adequate diagnostic yield, and safety profile.
