Core Tip

Core tip: The new flexible MicroCutter30 XChange can dissect the septum of a Zenker diverticulum (ZD) under flexible endoscopic vision control. The simultaneous division and closure of the cutting edge by the staple rows prevents major bleedings or perforations. The combination of a flexible endoscopy and a surgical stapler is a significant advantage in the treatment of ZD.
