Study summary

The aim of this study is to evaluate the ability of a ICG-fluorescence guidance complemented with enhanced reality to correctly document intestinal pre-anastomotic perfusion and to validate the accuracy of this technique with metabolic intestinal cells changes.

Read the detailed description

Accurate intraoperative evaluation of peri-anastomotic gastrointestinal tract perfusion is essential to reduce the risk of anastomotic complications such as leakage or strictures. Anastomotic leakage is the most dreadful complication of colorectal resections.

Intestinal microcirculation and viability is usually estimated from the color of the serosal surface, presence of peristalsis, pulsation and bleeding from the marginal arteries. This is subjective and based on the experience of the surgeon.

Fluorescence videography integrates a near-infrared endoscope able to detect the signal emitted by a fluorescent dye, Indocyanine Green (ICG), which is administered by intravenous injection. Fluorescence intensity is proportional to the amount of fluorescent dye diffused in the tissue and it consequently is a surrogate marker of tissue perfusion.

The hypothesis is that ICG-fluorescence guidance coupled with enhanced reality would allow a precise and rapid localization of the future anastomotic site in terms of optimal perfusion in laparoscopic colorectal resections.

In patients undergoing elective left-sided colonic resection by laparoscopic approach, resection site and anastomosis perfusion will be evaluated by :

  • the visual appreciation of the surgeon
  • the fluorescence-based enhanced reality, after injection of ICG and digital process.

A series of peri-operative samplings will also be carried out. In any case, the resection will be performed according to the surgeon's appreciation.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patient, male or female, from 18 years old
  • Patient with sigmoid diverticulosis or diverticulitis
  • Patient with colon
  • Patient with rectum malignancy
  • Patient with no to anesthesia and to colonic resection surgery

Exclusion criteria

Exclusion Criteria:

  • Patient undergoing emergency surgery
  • Patient undergoing abdomino-perineal resection
  • Patient undergoing colonic resection without anastomosis (Hartmann's colostomy)
  • Patient with proven or unclear allergic reactions
  • Pregnancy or breast-feeding
  • Patient in exclusion period (determined by a previous study or in progress)
  • Patient in custody

Terms in these criteria, in plain language(3)

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.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

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.

Study arms

  • Experimental
    Perfusion evaluation of anastomosis

    During left-sided colonic resections, anastomosis perfusion will be estimated by the visual appreciation of the surgeon and the ICG fluorescence-based enhanced reality. These two approaches will be compared.

    Procedure: Left-sided colonic resection

Interventions

  • ProcedureLeft-sided colonic resection

    During interventions, anastomosis perfusion will be estimated (outcomes: visual appreciation of the surgeon, ICG fluorescence-based enhanced reality and series of peri-operative samplings) in order to validate the accuracy of ICG fluorescence-based enhanced reality technique. In any case, the resection will be performed according to the surgeon's appreciation.

What researchers measure

Primary outcomes

  1. Correlation between the perfusion evaluated by the ICG fluorescence-based enhanced reality and the metabolic state of the intestine

    The perfusion evaluated by the ICG fluorescence-based enhanced reality, obtained by the digital process of the fluorescence dynamic signal, will be correlated to the metabolic state of the intestine, assessed by the measure of biological markers on several points of the intestine.

    Time frame: During surgery

Secondary outcomes

  1. Correlation between the intraoperative intestinal perfusion and the rate of anastomosis leakage

    The intraoperative intestinal perfusion on the anastomosis site, measured by fluorescence videography, will be correlated to the rate of anastomosis leakage.

    Time frame: During surgery

  2. Distance between the resection site based on the surgeon's appreciation and the resection site based on the digital analysis and the peri-operative samplings

    The distance between the resection site based on the surgeon's clinic appreciation and the resection site based on the digital analysis and the level of capillary lactates and mitochondria respiratory rate on different sites will be measured.

    Time frame: During surgery

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 Sep 2016 to primary completion in Sep 2018, 24 months.

Of 16 interventional studies with no phase under Diverticulitis, half reached primary completion within 36 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 57. This study's 24 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 Feb 12, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
