Learning Curve Analysis and Adverse Events After Implementation of Neurosurgical Laser Ablation Treatment

Objective and Methods: We conducted a retrospective review of the first 30 patients treated with stereotactic laser ablation (SLA) at our institution since the introduction of the technique in September 2019. We aimed to analyze our initial results and potential learning curve by investigating precision and lesion coverage and assessing the frequency and nature of adverse events according to the Landriel –Ibanez classification for neurosurgical complications. Results: Indications were de novo gliomas (23%), recurrent gliomas (57%), and epileptogenic foci (20%). There was a trend toward improvement of lesion coverage and target deviation, and a statistically significant improvement in entry point d eviation, over time. Four patients (13.3%) experienced a new neurological deficit, where three patients had transient and one patient had permanent deficits, respectively. Our results show a learning curve on precision measures over the first 30 cases. Based on our results the technique can safely b e implemented at centers with experience in stereotaxy.
