Intraoperative Hyperspectral Imaging for Laparoscopic Surgery

N/ANot Yet RecruitingNCT06700317

King's College London40 enrolled

Overview

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.

Outcomes

Primary Outcomes

Device safety

To demonstrate that under normal conditions of use, the performance characteristics of the device are those intended, enabling laparoscopic abdominal surgery to be safely performed using the UKCA-marked medical device (HSS1) as the primary surgical visualisation system.

Time frame: From enrollment to end of follow up (30 days)

Secondary Outcomes

Technological performance

To determine any undesirable side effects in technological performance and assess whether these constitute risks when weighed against the intended performance of the device.

Time frame: Duration of surgery

Utility and usability of tissue oxygenation saturation maps in bowel surgery

To assess the utility and usability of tissue oxygen saturation maps in bowel resection surgery for delineation of intestinal angiosomes and how the additional StO2 biomarker influenced clinical decision making

Time frame: Duration of surgery

Utility and usability of tissue oxygenation saturation maps in cholecystectomy

To perform retrospective analysis of the utility and usability of tissue oxygen saturation maps in cholecystectomy (not shown during procedure) for delineation of relevant anatomical structures within the surgical field.

Time frame: Duration of surgery

Human factors analysis on use of HSS1

To perform a human factor analysis of the use of the UKCA marked medical device (HSS1) in relation to surgical workflow and surgeon performance.

Time frame: Duration of surgery
