Force and fluorescence measurement system for consideration of stapler compressing parameter in distal pancreatectomy

Abstract

Currently, distal pancreatectomy using a stapler is often performed as a treatment for pancreatic cancer. However, leakage of pancreatic juice may occur in this surgery. One of the reasons of this is mentioned pancreatic membrane break due to stapler compression. Therefore, in order to observe the break of membrane and optimize the compression parameter of stapler that can suppress leakage of pancreatic juice, force and fluorescence measurement system during compression was developed. In compression test, difference of reaction force was confirmed when changing the compression speed. Fluorescence observation made it possible to visualize the site of membrane breaking on fundamental evaluation. In the future, examination of relation between various compression parameters and membrane break in combined experimental system will be performed.
