Endoscopic third ventriculostomy (ETV) is becoming a popular option of treatment in carefully selected patients with hydrocephalus (Drake et al., Childs Nerv Syst 25:467-472, 2009). The success or possible outcome of its application in treating hydrocephalus can be predicted by employing a preoperative scoring system. An example of such a system is the endoscopic third ventriculostomy success score (ETVSS). It could form a basis for decision-making and prognostication. This study aimed to evaluate ETVSS as a preoperative predictive tool in children with hydrocephalus who satisfy the inclusion criteria for the option of ETV procedure as treatment modality. This is a prospective hospital-based study of 68 children under 2 years of age that presented at the Lagos University Teaching Hospital (LUTH) out of 161 children with hydrocephalus from November 2014 to April 2016. The predicted ETVSS was calculated by the addition of patients’ age, presumed aetiology and prior shunting. These children were stratified into three groups according to ETVSS as higher score predicts better ETV outcome and vice versa. They were followed up for 6 months to determine the success rate of ETV. The age of the study population ranged from 0 to 24 months with a mean age of 5.52 ± 5.48 months. 69.1% of these patients were male and 30.9% were female with a male to female ratio of 2.2:1. The mean predicted ETVSS (48.82 ± 19.20%) and actual ETV success score (56.20 ± 15.10%) using the ANOVA were significantly related (p value < 0.05). This study concluded that the early outcome of ETV in children below 2 years of age with hydrocephalus is directly related to the preoperative ETVSS.

内窥镜第三脑室造口术成功率在撒哈拉以南非洲资源有限的三级中心预测68例脑积水患儿的近期预后

内窥镜第三脑室造口术（ETV）在精心选择的脑积水患者中正成为一种流行的治疗选择（Drake等，Childs Nerv Syst 25：467-472，2009）。可以通过术前评分系统预测其在治疗脑积水中的成功或可能的结果。这种系统的一个例子是内窥镜第三脑室造口术成功评分（ETVSS）。它可以作为决策和预测的基础。这项研究旨在评估ETVSS作为符合纳入标准的ETV手术治疗方法的脑积水患儿的术前预测工具。这是一项基于医院的前瞻性研究，研究对象为2014年11月至2016年4月在拉各斯大学教学医院（LUTH）中的161名脑积水儿童中的68岁以下的2岁儿童。预测的ETVSS通过添加患者来计算年龄，推测病因和事先分流。这些孩子根据ETVSS分为三组，因为较高的分数预示了较好的ETV结果，反之亦然。他们进行了6个月的随访，以确定ETV的成功率。研究人群的年龄为0到24个月，平均年龄为5.52±5.48个月。这些患者中男性占69.1％，女性占30.9％，男女之比为2.2：1。平均预测ETVSS（48.82±19.20％）和实际ETV成功分数（56.20±15）。10％）使用ANOVA显着相关（p值<0.05）。这项研究得出的结论是，2岁以下脑积水儿童的ETV早期结果与术前ETVSS直接相关。
