Abstract：Objective To evaluate the safety and efficacy of the Remebot robotic-assisted contact endoscopic technique for biopsy of intracranial lesions.Methods A retrospective analysis was conducted on the clinical data of 16 patients who underwent intracranial lesion biopsy between November 2023 and January 2024.Preoperative head CT and MRI T1-weighted 3D magnetization-prepared rapid gradient-echo sequences were performed.The CT and MRI data were imported into the Remebot robotic workstation to plan the puncture path.During surgery,the puncture procedure was visually observed under a contact endoscope to avoid blood vessels along the puncture path,distinguish target lesion tissue from normal brain tissue,and collect lesion samples for pathological examination to confirm the diagnosis.Results All 16 biopsies were successfully completed.Postoperative pathological diagnoses included 7 cases of diffuse astrocytoma and oligodendroglial tumor,6 cases of primary central nervous system diffuse large B-cell lymphoma,1 case of craniopharyngioma,1 case of cerebral tuberculoma,and 1 case of diffuse meningeal melanocytosis.The biopsy positive rate was 100%(16/16).No postoperative hemorrhage at the lesion site or along the puncture path was observed.Conclusion The Remebot robotic-assisted contact endoscopic technique can significantly improve the safety and efficacy of intracranial lesion biopsy and reduce postoperative complications.
