InTRaoperative Imaging DEvice Based on endogeNous opTical Properties to Evaluate Bowel Oxygenation in Colorectal Resections

Intuitive Surgical10 enrolled

Overview

The objective of the study is to assess the safety and technical feasibility of a new imaging system, used during colorectal resection surgery, named Trident in version 1.0, which could be used by the surgeon during colorectal procedures to obtain information on intestinal tissue oxygenation.

This is a prospective, non-randomized, single center, feasibility trial. All consecutive patients that fulfil the inclusion/exclusion criteria will be informed about the possibility to be included in the present clinical investigation. Only subjects that have signed the study informed consent will be included in the study. The Trident System v1.0 will be used only during approximately 2 to 5 minutes during a precise surgical step, i.e., just before the final resection of the surgical specimen. Patients will be prospectively followed at 30 days post-surgery. Data will be collected prospectively from the medical records.

Outcomes

Primary Outcomes

image quality (sharpness, brightness, etc) and surgeon's feedback regarding the ergonomics and safety of Trident System v1.0 during surgery.

descriptive analysis on the quality images by the engineering design team and feedback provided by clinical experts (surgeons) according to ad hoc form evaluating: 1) ergonomics aspects; 2) workflow; 3) risks of breaching sterility; 4) Speed of image acquisition.

Time frame: 30 days FU

Secondary Outcomes

- level of oxygenation (StO2) of the exteriorized colon before resection with the Trident System v1.0 - the level of oxygenation (StO2) provided by the system at the site chosen by the surgeon based on the clinical evaluation.

Measurement of StO2 values at the resection site determined by the surgeon based on his clinical judgment and measurement of StO2 levels over the entire length of the colon exteriorized and visible in the field of view of the Trident System v1.0.

Time frame: surgery day
