Objectives

Narrative objectives1

There are several methods to biopsy intraparenchymal brain lesions, including stereotactic biopsy and open block biopsy, both of which have advantages and disadvantages. We propose a novel biopsy method for intraparenchymal brain lesions, called boring biopsy which aims to overcome the drawbacks of each conventional method. The boring biopsy is minimally invasive and allows continuous specimens of sufficient volume to be obtained. This study aimed to assess the feasibility and efficacy of using boring biopsy for intraparenchymal brain lesions.

Assessment

Primary outcomes

The patient- and tumor-related characteristics of interest were sex, age, tumor location, the accuracy of target sampling, histopathology findings, and complications. The accurate biopsy point was defined as the correspondence between the preoperative target point and resected point, based on postoperative magnetic resonance imaging (MRI) or computed tomography (CT) scans.
