I have been very happy using the ViSiGi 3D® for my sleeve gastrectomy procedures. It is very easy to use and greatly simplifies the whole process of getting the bougie in the correct location and keeping it in place. It has saved me valuable time during my cases and stays in the correct location throughout my procedure. In addition, when I want to test my sleeve for leaks, the ViSiGi 3D® can be used without having to place another tube down saving more time and is safer to use.
