OBJECTIVE: Transcallosal microscopic and endoscopic excisions are both well established approaches to colloid cyst resection; however, there has been no clear consensus regarding the favored approach. We performed a systematic review comparing the transcallosal microscopic and endoscopic transcortical approaches for colloid cyst excision.
METHODS: We performed a systematic review from 2000-2018 of patients undergoing colloid cyst excision via a microscopic transcallosal or endoscopic transcortical approach where the surgical intent was gross total resection. Studies that included multiple approaches were included if the reported results were stratified by approach.
RESULTS: The microsurgical transcallosal approach had a higher rate of gross total resection when compared with endoscopic excision (96% for transcallosal vs. 78.5% endoscopic; P < 0.0001). There was also a lower recurrence rate with the transcallosal approach (0.98% vs. 2.16%; P = 0.0036); however, there was no difference in reoperation rates with similar length of follow-up (0.33% transcallosal, 0.61% endoscopic; P = 1.000). Endoscopy had lower overall morbidity when compared with transcallosal approaches (8.7% vs. 18.6%; P = 0.0001), including statistically significant lower rates of infection, infarct, and seizures in the endoscopic cohort. Rates of permanent memory deficit were similar (6.55% transcallosal vs. 4.5% endoscopic; P = 0.52). Shunt dependency was 9.8% after transcallosal excision versus 3.5% after endoscopic excision (P = 0.0002).
CONCLUSIONS: Modern series of colloid cyst excision continue to favor transcallosal approaches in achieving gross total resection. Nevertheless, endoscopic techniques have significantly reduced morbidity compared to transcallosal approaches, including lower rates of infection, infarct, and seizure. Endoscopic approaches also have a statistically significant decreased rate of shunt dependency-arguably the most important primary endpoint of surgery. With improving endoscopic technology and mastery of the technique, endoscopic excision is maturing into a standard first-line approach for colloid cyst excision.
