BACKGROUND: The sheath is a crucial piece of equipment during endoscopic third ventriculostomy (ETV). However, the normally used @entity1702 can not provide clear images around the tube. OBJECTIVE: We developed a new @entity4847 ( @entity4847 ) in order to overcome the inherent disadvantages of the @entity1702 ( @entity1702 ). MATERIAL AND METHODS: Between August 2010 and February 2013, a total of 120 @entity1276 @entity1 received ETV in our hospital. @entity1 were retrospectively divided into two groups, the @entity4847 group (TSG) and @entity1702 group (MSG). The success rate of the first puncture, the operative time and the incidence of complications were used to compare the efficiency between @entity4847 and @entity1702 . RESULTS: There were 32 @entity1 in the TSG and 88 @entity1 in the MSG. The success rate of the first puncture was 100% in the TSG and 87.5% in the MSG, respectively (p= 0.036). The operative time of the TSG was significant shorter than the MSG (p= 0.001). While the incidence of complications was similar between the two groups (p= 0.757). CONCLUSIONS: Compared with the tranditional @entity1702 , the newly developed @entity4847 for ETV is more efficient and showed lower risk. This may be explained by the better surgical view of the whole puncture channel provide by the @entity4847 .
