Brief summary: 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.

Detailed description: 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.

Eligibility criteria: Inclusion Criteria:

* Patient scheduled for a left-sided colorectal resection, irrespective of the surgical approach (open surgery, laparoscopic surgery,) because of:

  * Colon cancer OR
  * Sigmoid diverticular disease OR
  * Rectal cancer
* All genders
* Age \> 18 years old
* Ability to understand the information related to the study protocol

Exclusion Criteria:

* Pregnancy or breastfeeding
* Contraindications to anaesthesia
* Inability to provide a written informed consent
* Inclusion in a different ongoing clinical trial
* Emergency procedure
* Abdomino-perineal resection
* Hartmann procedure
* Patient is part of vulnerable population (e.g., prisoners, mentally disabled)

Primary outcomes:
measure: image quality (sharpness, brightness, etc) and surgeon's feedback regarding the ergonomics and safety of Trident System v1.0 during surgery.
timeFrame: 30 days FU
Secondary outcomes:
measure: - 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.
timeFrame: surgery day
