Endoscopic bimanual sharp dissection technique for gross-total resection of colloid cysts: technical note

Area of Science:

• Neurosurgery
• Minimally Invasive Procedures
• Neuroendoscopy

Background:

• Neuroendoscopic resection of colloid cysts is increasingly popular due to favorable outcomes and low complication rates.
• However, endoscopic approaches may have lower rates of gross-total resection compared to microsurgery, potentially increasing recurrence risk.
• A debate persists regarding the optimal surgical strategy for colloid cyst management.

Purpose of the Study:

• To describe a surgical technique for achieving gross-total resection of colloid cysts using neuroendoscopy.
• To present methods that ensure safe and complete removal of colloid cysts via a ventriculoscopic system.

Main Methods:

• The described technique involves a far anterolateral entry point and navigational guidance.
• Bimanual sharp dissection, use of the endoscopic sheath as a retractor, and specialized irrigation and hemostasis techniques are employed.
• The goal is to achieve gross-total resection safely.

Main Results:

• The technical note details a method for safe gross-total resection of colloid cysts.
• The described surgical nuances aim to overcome limitations of previous endoscopic approaches.

Conclusions:

• Gross-total resection should be the primary goal for endoscopic colloid cyst resection.
• The presented neuroendoscopic technique facilitates safe and complete removal, addressing concerns about recurrence.
