Intraoperative Hyperspectral Imaging for Laparoscopic Surgery

Intraoperative Hyperspectral Imaging for Laparoscopic Surgery (LapHSI): a Multicentre Post-market Clinical Study

The study aims to evaluate the use of the HyperSnap Surgical System (HSS1) during laparoscopic surgeries, specifically in bowel resections and cholecystectomies.

The study will observe patients undergoing bowel resection and cholecystectomy surgeries to determine if HyperSnap Surgical System (HSS1), as a primary visualisation tool, functions safely and capably as a laparoscopic imager. In addition, we will see if it subjectively improves the identification of critical anatomical structures. In addition, the study will secondarily assess how StO2 information may be included in the surgical workflow and how surgeons may react to this additional information.
