Study Summary:
A comparative study was conducted to evaluate the effectiveness and safety of two different surgical methods for intraparenchymal brain lesion biopsy: frameless robot-assisted stereotactic biopsies and image-guided biopsies. The study included 250 patients from two French university hospitals, with 131 undergoing robot-assisted biopsies and 119 undergoing image-guided biopsies.
Key Findings:
- The diagnostic yield was similar for both methods (96.2% for robot-assisted and 95.8% for image-guided; p = 1.000).
- Postoperative complication rates were comparable (13% for robot-assisted and 14% for image-guided; p = 0.880).
- Robot-assisted biopsies had a longer mean duration (61.9 ± 25.3 minutes) compared to image-guided biopsies (47.4 ± 11.8 minutes; p < 0.001).
- In patients on anticoagulant/antiplatelet therapy, the incidence of postoperative intracerebral hemorrhage >10 mm was lower in the robot-assisted group (5%) than in the image-guided group (36.8%; p < 0.001).
Importance:
This study contributes to the literature by providing a direct comparison between two modern neurosurgical techniques for brain lesion biopsies. It highlights that both methods are safe and efficient, with the robot-assisted approach having a longer surgery duration but a lower risk of significant postoperative hemorrhage in patients on blood-thinning medications.
