AbstractOBJECTIVEColloid cysts of the third and lateral ventricles have traditionally been treated by transfrontal and transcallosal microsurgical resection or by stereotactic aspiration. Recently rigid and flexible ventricular endoscopic techniques have been used to treat these lesions. Our study was undertaken to examine the efficacy of rigid endoscopy in the resection of colloid cysts.METHODSFifteen patients with a radiological diagnosis of colloid cysts were given the option of Diagnosis of collid cysts were given the option of undergoing either endoscopiv surgery or car niotomy. the average tumor size was 1.43 cm. Fourteen patients underwent planned endoscopic resections, and a carniotomy was performed intially in one patient.RESULTSEntire tumor resection was achieved with the endoscope in 12 patients (86%). craniotomy was required for two colloid cysts that could not be resected endoscopically. In total, complete radiographic resections were achieved in 14 patients (93%). There were no permanent complications, although postoperactive deficts included short-term memory loss and hemiparesis, each one in patient.CONCLUSIONRigid endoscopy affords good optical resolution, high magnification, and excellent illumination. Total or near total resection of colloid cysts should be the goal for all patients and can be achieved using the rigid endoscope, with little morbidity, shortened operative time, reduced length of stay, and resolution of symptoms. Although long-term follow-up is needed, we think that endoscopy should be considered as a primary treatment for most patients.
