Trial summary

Properly documenting withdrawal time in colonoscopy is essential for quality assessment and cost allocation. However, reporting withdrawal time has significant interobserver variability. Additionally, current manual documentation of endoscopic findings is time-consuming and distracting for the physician. Read more about this study

About this study

Properly documenting withdrawal time in colonoscopy is essential for quality assessment and cost allocation. However, reporting withdrawal time has significant interobserver variability. Additionally, current manual documentation of endoscopic findings is time-consuming and distracting for the physician. This trial examines an artificial intelligence based system to determine withdrawal time and create a structured report, including high-quality images (AI) of detected polyps and landmarks.

Read the detailed description

This study aims to compare withdrawal time precision calculated by an AI system with examiner-reported times during colonoscopy, also evaluating endoscopists' satisfaction with the images included in the AI-generated reports. The study will be single-center and endoscopist-blinded, where 138 patients are expected to be recruited, taking polyp detection rates and potential dropouts into consideration. Manual annotation of withdrawal times from examination recordings will establish gold standard annotations. The AI system performs a frame-by-frame analysis of endoscopy recordings, predicting endoscopic findings. Using a rule-based logic, the method calculates withdrawal time for the examination and automatically generates a report for the examination. The study will include consenting adult patients eligible for colonoscopy, excluding those meeting specific criteria.

In this observational study, the withdrawal time for the examinations of all recruited patients is estimated by both the physician and the AI method. The study does not relate to any particular indication, and any patient that is appointed for a colonoscopy and does not meet the exclusion criteria can be recruited. The AI method operates in the background, having no influence on the examination's process, or outcome. The standard procedure requires physicians to estimate the withdrawal time and document it in the examination report. Simultaneously, the proposed AI method also computes the withdrawal time for all patients in the background, without affecting the physician, the examination, or the outcomes of the examination. Importantly, the physician remains blinded to the AI model's output.

To establish the gold standard withdrawal time, manual calculations will be performed using the recorded examination data for all patients. This gold standard is used for evaluating errors in withdrawal time estimation made by both the physician and the AI method. Subsequently, a comparative analysis is conducted to assess the disparities between the physician's estimations and those of the AI method.

Furthermore, the AI method captures characteristic images of anatomical landmarks and notable events, such as polyp resections, during the examination. A panel of certified endoscopists will rigorously evaluate the quality and relevance of these selected images.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • EndoMindDevice

    Withdrawal time is calculated and an image report is generated using the EndoMind system.

Study groupRoleWhat they receive
Experimental: Intervention armAll patients within the study are included in the intervention arm: The withdrawal time for the interventions for all patients is documented by the physician and the proposed AI system.
Receives: Device: EndoMind

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Withdrawal time error comparison for colonoscopies using the proposed AI system versus physician estimation

    The error between gold standard withdrawal time and the withdrawal time estimated from the proposed AI system and the physician are compared for the same examination.

    Measured: Through study completion, an average of 5 months

Secondary outcomes (3)
  1. Image quality satisfaction

    A board of endoscopy experts receives the reports generated by the proposed system and evaluate the quality and satisfaction for the images included in the report. Evaluation will be performed on a Likert scale from 1 to 5.

    Measured: Through study completion, an average of 5 months

  2. Subgroup analysis for withdrawal time calculation error based on the presence or absence of resections in the examination.

    Interventions will be split into two categories, those containing at least one resection and those without any resections.The error between gold standard withdrawal time and the withdrawal time estimated from the proposed AI system and the physician are compared for each subgroups of examinations separately.

    Measured: Through study completion, an average of 5 months

  3. Number of examination where withdrawal time could not be determined

    Evaluation of the number of examinations where the withdrawal time could not be calculated and the causes.

    Measured: Through study completion, an average of 5 months

Questions about this trial

What is this clinical trial studying?

An observational study of Colonoscopy, run by Wuerzburg University Hospital at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Withdrawal time error comparison for colonoscopies using the proposed AI system versus physician estimation (time frame: Through study completion, an average of 5 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Apr 2025.
