摘要 目的：探讨立体定向脑内窥镜手术临床应用价值。方法：对位于脑深部或重要功能区的病变，采用CT引导立体定向技术施行脑内窥镜手术50例；其中包括脑瘤切除，异物、囊肿、脓肿或囊虫摘除，脑内病变活检，血肿排空，脉络丛烧灼等手术。术中成功应用了双套管法和钬激光。结果：手术有效率96%(术后1月)。无手术死亡及术后昏迷、偏瘫、颅内出血和感染等严重并发症。结论：此方法使以往立体定向穿刺的不可视性，变为可视性操作；扩大了手术范围，提高了手术安全性。

Abstract Objective: To assess the clinical value of stereotactic endoscopic operations. Methods: 50 brain lesions, located in deep brain or main functional areas, were treated with CT-guided stereotactic endoscopic operations. The operations included: excision of brain tumor; extirpation of foreign body, cyst, abscess and cerebral cysticercosis; biopsy of lesion; evacuation of hemotoma and cauterization of choroid plexus. Double-tuber and holmium laser were successfully used during the operations. Results: The effective rate was 96%, one month after the operations. There were no serious complications, such as coma, hemiparalysis, intracranial hematoma and infection. Conclusion: This method makes the process of stereotactic puncture from blindness to vision, which broadens the operative range and increases the operative safty.
