“…Its anatomical components, surgical technique, and outcomes have been described. 2,4,6,[8][9][10][11][12][17][18][19][20][21][22][23][24] The published rates of complications for transcallosal surgery vary widely and range from 6% to 67%, 2,6,[8][9][10][11][13][14][15]18,21,22,[25][26][27][28][29][30] depending on the definition of complications. The morbidity risk we observed was 50%, which falls within the range of previously published rates.…”

“…3,12,17,28 Although this procedure is associated with low morbidity rates and is initially effective, the remaining cyst wall can continue to secrete cyst contents, decreasing the long-term efficacy of this technique. 1,11 Open surgery is traditionally considered the gold standard for the treatment of third ventricle colloid cysts, with many authors having reported a residual/recurrence rate ranging from 0% to 1.1% when using a transcallosal or transfrontal-transventricular approach. 5,6,8,10,13,18,19,26 How ever, these approaches have high operative morbidity and mortality rates because they are potentially associated with disabling complications such as venous infarction, hemiparesis, memory deficit, subdural hematoma, meningitis, and ventriculitis.…”

Colloid cysts are histologically benign lesions whose primary goal of treatment should be complete resection to avoid recurrence and sudden death. Open surgery is traditionally considered the standard approach, but, recently, the endoscopic technique has been recognized as a viable and safe alternative to microsurgery. The endoscopic approach to colloid cysts of the third ventricle is usually performed through the foramen of Monro. However, this route does not provide adequate visualization of the cyst attachment on the tela choroidea. 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. Between April 2005 and February 2011, 19 patients with symptomatic colloid cyst of the third ventricle underwent an endoscopic transfrontal-transforaminal approach. Five of these patients, harboring a cyst firmly adherent to the tela choroidea or attached to the middle/posterior roof of the third ventricle, required a combined ETTA. Postoperative MRI documented a gross-total resection in all 5 cases. There were no major complications and only 1 patient experienced a transient worsening of the memory deficit. To date, no cyst recurrence has been observed. An ETTA is a minimally invasive procedure that can allow for a safe and complete resection of third ventricle colloid cysts, even in cases in which the lesions are firmly attached to the tela choroidea or located in the middle/posterior roof of the third ventricle.

“…Colloid cysts are benign tumors that most commonly appear in the third ventricle and account for 0.5–2.0% of all central nervous system tumors (1–5). They are composed of an outer fibrous layer and an inner epithelium of ciliated or mucin-producing cells (6, 7).…”

Microsurgical vs. Endoscopic Excision of Colloid Cysts: An Analysis of Complications and Costs Using a Longitudinal Administrative Database

ObjectiveOpen microsurgical and endoscopic approaches are the two main surgical options for excision of colloid cysts. Controversy remains as to which is superior. Previous studies consist of small cohort sizes. This topic has not been investigated using national administrative claims data which benefits from larger patient numbers.MethodsCurrent Procedural Terminology (CPT) and International Classification of Disease version 9 (ICD-9) coding at inpatient visit was used to select for index surgical procedures corresponding to microsurgical or endoscopic excision of colloid cysts. Comorbidities, costs, and complications were collected.ResultsWe identified a total of 483 patients. In all, 240 were from the microsurgical cohort and 243 were from the endoscopic cohort. The two groups displayed similar demographic and comorbidity profiles. Thirty-day post-operative complications were also similar between groups with the exception of seizures and thirty-day readmissions, both higher in the open surgical cohort. The seizure rates were 14.7 and 5.4% in the microsurgical and endoscopic cohorts, respectively (p = 0.0011). The thirty-day readmission rates were 17.3 and 9.6% in the microsurgical and endoscopic cohorts, respectively (p = 0.0149). Index admission costs and 90-day post discharge payments were higher in patients receiving microsurgical excision.ConclusionAn analysis of administrative claims data revealed few differences in surgical complications following colloid cyst excision via microsurgical and endoscopic approaches. Post-operative seizures and thirty-day readmissions were seen at higher frequency in patients who underwent microsurgical resection. Despite similar complication profiles, patients undergoing microsurgical excision experienced higher index admission costs and 90-day aggregated costs suggesting that complications may have been more severe in this group.
