This prospective multicenter randomized trial evaluated the safety and feasibility of a robotic system versus conventional freehand technique for CT-guided percutaneous biopsy of thoracoabdominal lesions in 165 participants. The robot-assisted group achieved a significantly higher technical success rate of 97.56% compared to 62.65% in the freehand group (P < .001).

Key findings

  • Robot-assisted group had a technical success rate of 97.56% vs 62.65% in the freehand group (P < .001).
  • Mean targeting error was lower in the robot-assisted group: 1.7 mm vs 4.5 mm (P < .001).
  • Fewer CT scans were needed in the robot-assisted group: 4.3 vs 5.2 (P = .002).
  • Complications during lung biopsies were lower in the robot-assisted group: 4.88% vs 16.87% (P = .014).

Why it matters

The findings suggest that robotic assistance in CT-guided biopsies can enhance precision and reduce complications, which may improve patient outcomes and procedural efficiency in clinical practice.
