We read with great interest the article by Mohammed et al. titled “The safety and efficacy of frame-based stereotactic biopsy of brain lesion.”
The existing literature well regards frame-based stereotaxy as the gold standard procedure for brain biopsy due to its high precision.,, We recently published a systematic review and meta-analysis comparing frame-based and frameless intracranial stereotactic biopsy techniques. After critically and carefully reviewing this article, we would like to respectfully share a few concerns pertaining to this study.
Although the authors have reported complications stratified by time, anatomical location, and type of anesthesia, the authors should also report if there were any neurological deficits as a result of the procedure with further stratification with respect to the type of deficit, that is, transient vs. permanent. It is quite important for the readers to know what complications occurred in the majority in each of deeper and superficial lesions groups. In addition, comparison between the patient groups with and without complications in terms of duration of hospital stay with a specific mention of the outlier complications would have been useful.
The authors have not mentioned what statistical program was used in the analysis. It would be interesting to see the results of a multivariable logistic regression model to determine whether the duration of hospital stay depends on one or more of the factors: age of the patient, the type of anesthesia administered (local vs. general) or the type of complication (hemorrhage, neurological deficit, or others). A subgroup analysis in terms of diagnostic yield stratified by patient age groups (pediatric vs. adults) and anesthesia administered (local vs. general) should also be reported.
We appreciate the authors for reporting their experience with frame-based intracranial stereotactic biopsy technique and validation of the existing literature.
