Comparative Outcomes of Transcallosal Microsurgical and Endoscopic Transcortical Approaches for Colloid Cyst Removal: A Single-Center Retrospective Analysis

Objectives:Colloid cysts in the third ventricle are benign intraventricular tumors, with surgical treatment often recommended. This study compares the outcomes of endoscopic transcortical and microscopic transcallosal approaches for colloid cyst removal.Methods:A retrospective analysis of 22 patients (15 male, 7 female) who underwent colloid cyst resection between March 2012 and December 2018 was performed. Patients underwent either a transcallosal approach (14 patients) or an endoscopic approach (8 patients). Descriptive statistics and various tests were utilized to analyze the data.Results:Complete resection was achieved in 85% of transcallosal cases and 25% of endoscopic cases. Complications were fewer in the transcallosal group, with two patients experiencing memory loss and disconnection syndrome. The endoscopic group had more complications, including left-side weakness, dysarthria, and CSF leak. Surgery duration was shorter for the transcallosal group (2.5 hours) than the endoscopic group (3.25 hours). Hospital stay duration was also shorter for the transcallosal group (4 days) than the endoscopic group (6 days). Glasgow outcome scale results favored the transcallosal group.Conclusion:Our study demonstrated that total resection was more common in transcallosal surgery, which also had better Glasgow outcome scale results, shorter surgery times, and reduced hospitalization durations.
