Endoport-Guided Endoscopic Excision of Intraaxial Brain Tumors

Area of Science:

• Neurosurgery
• Minimally Invasive Surgery
• Endoscopic Techniques

Background:

• Traditional transcortical approaches for deep brain tumors rely on spatula-based retraction, potentially causing significant brain injury.
• Recent advancements include transparent cylindrical or tubular retractors (endoports) for stable access to deep lesions.
• Endoports combined with endoscopes offer enhanced visualization and reduced retraction trauma compared to standard microsurgery.

Purpose of the Study:

• To describe the surgical technique of endoport-guided endoscopic excision for deep-seated intraaxial brain tumors.
• To highlight the advantages of the endoport technique in neurosurgery.
• To discuss the safety and efficacy of this minimally invasive approach.

Main Methods:

• Detailed description of the endoscopic endoport technique used at the institution.
• Illustrative case examples are provided to demonstrate the procedure.
• Literature review of intraventricular and intraparenchymal port surgery.

Main Results:

• The endoport technique offers advantages such as reduced focal brain injury and minimized white matter disruption.
• It ensures a stable surgical corridor and protects surrounding tissues from iatrogenic damage.
• Analysis of literature supports the feasibility and safety of port surgery for brain tumors.

Conclusions:

• Endoport-assisted endoscopic resection is a safe and effective alternative for intraventricular and intraparenchymal brain tumors.
• This technique minimizes surgical trauma and improves outcomes for deep-seated lesions.
• It represents a significant advancement in minimally invasive neurosurgical oncology.
