BACKGROUND
We describe the resection of cerebellar cystic tumors using pure neuroendoscopy. This technique consists of performing all of the procedures under an endoscopic view, with the instruments introduced into the operative field coaxially to the endoscope through a trocar.
CASE DESCRIPTION
Three cases of cerebellar cystic lesions (two pilocytic astrocytomas and one hemangioblastoma) were approached using the pure neuroendoscopic technique. Under general anesthesia and prone positioning, a suboccipital burr hole was created. The endoscope was introduced into the tumor cavity, and a reddish nodule was identified. The monopolar electrode was used to coagulate and dissect the surrounding nodular tissue. Grasping forceps were used to remove the nodule. There were no complications related to tumor removal, and the patients recovered from their symptoms. The follow-up images showed reduction of the cavity with no contrast enhancement.
CONCLUSION
The pure neuroendoscopic technique was shown to be minimally invasive and a successful and secure method to treat cystic cerebellar tumors.
背景
我们描述了使用单纯神经内镜切除小脑囊性肿瘤的方法。该技术包括在内镜视野下完成所有操作，通过套管针将器械与内镜同轴引入术野。
病例描述
采用单纯神经内镜技术处理了3例小脑囊性病变（2例毛细胞型星形细胞瘤和1例血管母细胞瘤）。在全身麻醉及俯卧位下，制作枕下钻孔。将内镜引入肿瘤腔，发现一个红色结节。使用单极电极凝固并分离周围的结节组织。用抓钳取出结节。未出现与肿瘤切除相关的并发症，患者症状得到缓解。随访影像显示腔隙缩小，无强化。
结论
单纯神经内镜技术被证明是一种微创、成功且安全的治疗小脑囊性肿瘤的方法。
