摘　　要：Background The goal of this study is to show the feasibility and benefits of using the simultaneous biportal endoscopic procedure to treat pineal tumors in patients with obstructive hydrocephalus.Methods We retrospectively reviewed three patients with pineal tumors and acute obstructive hydrocephalus who were treated in one session with a frameless stereotactic guided simultaneous biportal endoscopic third ventriculostomy and endoscopic tumor biopsy performed through two separate ports using one rigid ventriculoscope.Results In the three patients,ventriculostomy and endoscopic biopsies were conducted.There was no death or morbidity throughout the 45-min procedure.All of the patients’histological findings were confirmed.Germinoma was diagnosed in two patients who recieved postoperative radiotherapy,and the third patient diagnosed with a pineocytoma.Magnetic resonance imaging with flow-sensitive sequences was used to confirm ventriculostomy patency in all patients 6 months after the surgery.Conclusion Biportal endoscopic approach enables better visual control of both procedures.Furthermore,it allows the surgeon to safely pass the ventriculoscope via the foramen of monro,even if it is narrow.Moreover,during endoscopic tumor biopsy and third ventriculostomy,the intracranial pressure can be smoothly managed using the outlet tubes accessible.This treatment may be an alternative to traditional uniportal endoscopic operations in certain patients.
