Minimally Invasive Endoscopic Approach to Large Intraventricular Tumors.

AIM: To analyze the safety and effectiveness of the minimally invasive endoscopic approach in the treatment of large intraventricular tumors. MATERIAL and

METHODS

We retrospectively reviewed the demographic, radiological, and surgical data of 8 patients who were operated on using the endoscope-plus-port technique for large (>5 cm) intraventricular tumors at our clinic between 2015 and 2020. All procedures were performed using the minimally invasive endoscopic approach.

RESULTS

The cohort comprised 3 females and 5 males, with a mean age of 40.88 years. All tumors were located in the lateral ventricle; near-total resection was achieved in 3 patients and subtotal resection in 5 patients. External ventricular drainage was inserted in all patients postoperatively. The histological diagnosis was neurocytoma in 3 patients, glioblastoma in 2 patients, metastasis in 2 patients, and a grade II meningioma in 1 patient. No complications or mortality were reported in the 31-month follow- up period.

CONCLUSION

Safe and effective tumor resection of intraventricular tumors is possible using the endoscope-plus-port, even in tumors >5 cm. This technique permits dynamic mobilization and facilitates bimanual operation, increasing resection rates and improving outcomes for these tumors.
