Recently, 25-gauge vitrectomy has become more popular. However, most still perform the surgery in pediatric patients without the use of the trocars and cannulas as in adult vitrectomies.
We described a simple modification using adult 25-gauge cannulas and 270-silicone watzke sleeves, enabling these instruments to be used in pediatric cases. The sleeve is cut into segments of 2 mm in length, and then introduced up the shaft of the 25-gauge trocar. One is introduced first, and a second one is introduced on top of the first one. This secures the two sleeves on the shaft of the trocar, such that they act as a spacer. The effective shaft of the trocar was then reduced to 2 mm in length.
This method enabled successful surgery in two cases.
This allows the adaptation of the standard 25-gauge system for pediatric cases with only the slightest modification needed.
近来，25G玻璃体切除术愈发普及。然而，多数情况下，小儿玻璃体切除手术仍未像成人玻璃体切除术那样使用套管针。
我们描述了一种简单的改良方法，使用成人25G套管和270型硅胶瓦茨克套管，使这些器械能够用于小儿病例。将套管切成2毫米长的小段，然后沿25G套管针的针杆插入。先插入一段，然后在第一段之上再插入一段。这样就将两段套管固定在套管针的针杆上，起到间隔物的作用。此时套管针的有效针杆长度减至2毫米。
该方法使两例手术成功。
这使得标准的25G系统只需稍作修改就能适用于小儿病例。
