Endoscopic Colloid Cyst Resection: A Case Series and Systematic Review

Area of Science:

• Neurosurgery
• Minimally Invasive Surgery
• Neuroendoscopy

Background:

• Endoscopic surgery is a minimally invasive alternative to microsurgery for intraventricular lesions like colloid cysts.
• While increasingly used, long-term outcomes data for endoscopic techniques are limited.
• Microsurgical resection remains a common procedure for colloid cysts.

Purpose of the Study:

• To assess clinical outcomes of endoscopic colloid cyst resection at a single institution.
• To compare endoscopic resection outcomes with published data on open and other endoscopic series.
• To evaluate the efficacy and safety of the endoscopic approach for colloid cyst removal.

Main Methods:

• Retrospective analysis of consecutive patients undergoing endoscopic colloid cyst resection (2014-2025).
• Evaluation of demographics, preoperative hydrocephalus, complications, recurrence, and reoperation rates.
• Systematic review and comparison with published literature on open and endoscopic approaches.

Main Results:

• 59 patients analyzed; 96.6% achieved gross total resection (GTR).
• Only one reoperation was needed for hydrocephalus, not recurrence.
• No shunt dependency, infections, or mortality observed.

Conclusions:

• Endoscopic resection at this center achieved a high GTR, superior to other series.
• Systematic review indicated significantly improved overall morbidity with endoscopic resection.
• The endoscopic approach is effective and safe for colloid cyst resection.
