ABSTRACT The management of colloid cyst remains controversial, evaluation of the competing methods seems to be necessary. We report on our experience with colloid cysts in the last decade: ten were managed solely endoscopically, 10 were resected microsurgically (9 via a transcortical/transventricular, 1 via a transcallosal approach). The outcome in the endoscopic group was excellent in 9 cases and unsatisfying in 1 case (recurrence). In the microsurgical group we achieved a good outcome in 5 of 10 cases, a fair outcome in 4 cases and 1 lethal outcome (caused by pulmonary embolism). Complications in the endoscopic group: one intraoperative bleeding, 1 stitch granuloma, 1 mispuncture of the ventricle, and 1 meningitis. Complications in the microsurgical group: 1 subdural effusion, 1 flap infection, 1 mild hemiparesis, 1 transient impairment of consciousness and 1 pulmonary embolism. Mean operative time and length of hospitalization of the endoscopic group were clearly shorter than in the microsurgical group: 91 min versus 267 min time of surgery, 5.1 days versus 18.9 days of hospitalization. Complete resection was achieved in 8 of 10 cases of microsurgery, and in 3 of 10 cases in endoscopy. Endoscopic management results in lower costs and superior patients' comfort. The reduced number of total resections in the endoscopic group may lead to a higher recurrence rate in long-term follow-up, which might be a serious disadvantage of endoscopy. However, more experience in the endoscopic techniques may result in a higher rate of total resection of colloid cysts.

    ABSTRACT: Microsurgical resection, stereotactic aspiration and VP shunt have for years been the choice options for the treatment of colloid cysts of the third ventricle. Recently, endoscopic approaches have aroused increasing interest and gained acceptance. Although safer, this minimally invasive approach is considered less efficacious than microsurgery. Relatively long-term results are now available and some conclusions might be inferred on the usefulness of this procedure. Between 1994 and 2005, 61 patients harbouring a colloid cyst of the third ventricle were treated with neuroendoscopic technique in 11 Italian neurosurgical centres. Cyst diameters ranged from 6 to 32 mm. A flexible endoscope was used in 34 cases, a rigid one in 21, both instruments in six. The technique consisted in cyst fenestrations, colloid aspiration, coagulation of the internal cyst wall and, occasionally, capsule excision. Mean postoperative hospital stay was 6.7 days. Early postoperative neuroimaging revealed a cyst residue in 36 cases (mean diameter 4.3 mm). There were two complications (3.2%). Follow-up varied between 1 and 132 months (mean 32 months, more than 5 years in 17 patients). There were seven asymptomatic recurrences, three of them evolving from a previous residue. The endoscopic approach to the treatment of colloid cysts is safe, effective and well accepted by patients. Although asymptomatic, recurrences (11.4%) cast a persisting shadow on the long-term results, and, therefore, the controversy with the traditional microsurgical treatment remains open.
