TL;DR: Endoscopic excision is a safe and effective, minimally invasive method for colloid cyst removal and even a subtotal excision of these slow-growing cysts may be acceptable when experience with the endoscope is limited.

Abstract: Background : The operative approaches for colloid cyst excision are varied with open microsurgical excision still being considered as the "gold standard". Endoscopic removal of these cysts is gaining in popularity. Aims : To document the efficacy and safety of the endoscope for colloid cyst excision. Materials and Methods : Retrospective study of all the patients who underwent endoscopic colloid cyst excision between January 2000 and March 2009. Patient records, radiological images and operative notes were assessed. Follow-up data including clinical and radiological details were retrieved. Results : Fifty-nine cases underwent endoscopic surgery during the study period. Gross total excision of cyst (with small residual nubbin) could be achieved in 46 (78%) patients. Others patients underwent: near-total excision (seven); partial excision (five); and cyst aspiration (one). A two-port technique for achieving excision was used in 18 patients. There was one death due to fulminant meningitis. No patients had recurrence, follow-up till 99 months. Two patients required ventriculo peritonealshunt for persistent hydrocephalus. Conclusions : Endoscopic excision is a safe and effective, minimally invasive method for colloid cyst removal. Even a subtotal excision of these slow-growing cysts may be acceptable when experience with the endoscope is limited.

Endoscopic Versus Microsurgical Resection of Colloid Cysts: A Systematic Review and Meta-Analysis of 1278 Patients
TL;DR: Microsurgical resection of colloid cysts is associated with a higher rate of complete resection, lower rate of recurrence, and fewer reoperations than with endoscopic removal, however, the rate of morbidity is higher with microsurgery than withendoscopic removal.

Neuroendoscopic Resection of Intraventricular Tumors: A Systematic Outcomes Analysis
TL;DR: Neuroendoscopic resection appears to be a safe and reliable treatment option for patients with intraventricular tumors of a particular morphology when performed on small, cystic tumors and when neural navigation or stereotaxy is used.
Endoscopic Resection of Colloid Cysts: Use of a Dual-Instrument Technique and an Anterolateral Approach
TL;DR: High rates of complete colloid cyst resection, with low morbidity, are possible with an anterolateral endoscopic approach with dual-instrument technique, which supports the findings of other endoscopists that show how technical modifications to traditional endoscopic approaches can produce favorable results.

Management of colloid cyst of third ventricle.
TL;DR: Although total excision should be aimed, subtotal excision and coagulation of residual cyst wall usually results in good long-term results without any growth of remnant wall, so conversion to an open procedure may be required in some patients.

TL;DR: The combined endoscopic transforaminal-transchoroidal approach (ETTA), providing exposure of the entire cyst and a better visualization of the tela choroidea, could increase the chances of achieving a complete cyst resection.

Natural history of asymptomatic colloid cysts of the third ventricle.
Bruce E. Pollock,John Huston +1 more
TL;DR: Patients in whom asymptomatic colloid cysts are diagnosed can be cared for safely with observation and serial neuroimaging, and if a patient becomes symptomatic, the cyst enlarges, or hydrocephalus develops, prompt neurosurgical intervention is necessary to prevent the occurrence of neurological decline from these benign tumors.
