Abstract

Background: Colloid cysts are considered rare benign tumors at the 3rd ventricle. Best surgical option for such tumors has not been established, however endoscopic approaches have been gaining popularity and have been proved to be an effective modality. We aimed to assess surgical outcomes of endoscopic resection of colloid cysts with evaluation of extent of resection and rate of complications.
Materials and methods: A retrospective cohort study was conducted to investigate surgical outcomes of patients who had undergone endoscopic resection of colloid cyst. Pre-operative clinical and radiological data were collected. Operative details, extent of resection and postoperative complications were estimated.
Results: In this study 27 cases had undergone endoscopic resection of colloid cyst in the period from January 2016 to January 2021. Patients were of mean age 32.7±10.9 years (17 patients were males). Headache was the most common presentation in (81.5%) of our patients. Complete resection was reported in 22 cases (81.5%), while subtotal resection with coagulation of residual adherent parts was done in 5 cases (18.5%).3 patients (11.1%) had postoperative wound infection, 2 patients (7.4%) experienced postoperative transient memory deficits, and only one patient (3.7%) had postoperative fulminant meningitis, and this was our mortality case. EVD was inserted in 9 patients (33.3%), but only 2 patients (7.4%) who further had a permanent VP shunt.
Conclusion: Endoscopic resection of 3rd ventricle colloid cysts is an effective procedure that provides gross total resection in most patients and has lower morbidity and mortality rates.
