A dual-view endoscope with image shift

We present a new endoscopic system that provides two different views simultaneously, one is a wide view (120 degrees) and the other is a zoomed view with image-shift mechanism. A Porro prism (II) is used to sh...

Increased insufflation pressure enhances the development of liver metastasis in a mouse laparoscopy model

Background: The effect of different insufflation pressures and durations of CO2 pneumoperitoneum on the growth of liver metastasis was investigated in a mouse model. The possible mechanisms involved in the pre...
