Study 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.

Read the 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.

    • Rectal cancer
  • All genders
  • Age > 18 years old
  • Ability to understand the information related to the study protocol

Exclusion Criteria:

  • Abdomino-perineal resection
  • Hartmann procedure
  • Patient is part of vulnerable population (e.g., prisoners, mentally disabled)
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. 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

  1. - 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

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jul 2023 to primary completion in May 2024, 10 months.

Of 404 interventional studies with no phase under Colonic Neoplasms, half reached primary completion within 30 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 51. This study's 10 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 22, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
