About this study

Official title: Web-based Learning Module to Increase the Accuracy of Optical Diagnosis for Detecting the Invasive Pattern of Colorectal Polyps (LODIP Study). Randomised Controlled Trial

International guidelines recommend deciding the treatment of colorectal lesions based on the estimated histology by endoscopic optical diagnosis. However, the theoretical and practical knowledge on optical diagnosis is not widely expanded

The mail goal of this randomised controlled trial is to compare the pooled sensitivity of optical diagnosis for predicting deep submucosal invasion in large non-pedunculated polyps > 20 mm assessed in routine colonoscopies of gastroenterologists attending a e-learning module (intervention group) vs gastroenterologists who do not (control group)

Read more

The main questions the study aims to answer are:

  • Is the pooled sensitivity of optical diagnosis for predicting deep submucosal invasion in large non-pedunculated polyps assessed in routine colonoscopies increased in those gastroenterologists participating in the e-learning module?
  • Is the pooled diagnostic accuracy of optical diagnosis for predicting deep sm invasion in large non-pedunculated polyps ≥ 20 mm assessed in routine colonoscopies increased in those gastroenterologists participating in the e-learning module?
  • In lesions with submucosal invasion, is the en bloc and complete resection rate (R0) increased in those gastroenterologists participating in the e-learning module?
  • In lesions referred to surgery, is the pooled benign polyps rate decreased in those gastroenterologists participating in the e-learning module?
  • In lesions treated with advanced en bloc procedures (ESD, TAMIS, fullthickness resection), is the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion increased in those gastroenterologists participating in the e-learning module?
  • In lesions treated with piecemeal endoscopic resection, is the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion decreased in those gastroenterologists participating in the e-learning module?
  • Is the diagnostic accuracy for predicting deep submucosal invasion in a test with pictures increased after participating in the e-learning module?

The participants (or subjects of study) are gastroenterologists. They will be randomised to do the e-learning course (intervention group) or not (control group).

Researchers will compare clinical outcomes of gastroenterologists participating in the e-learning module vs gastroenterologists not participating in the e-learning module to see if:

  • the pooled sensitivity of optical diagnosis for predicting deep submucosal invasion in large non-pedunculated polyps > 20 mm assessed in routine colonoscopies is increased.
  • the pooled diagnostic accuracy of optical diagnosis for predicting deep sm invasion in large non-pedunculated polyps > 20 mm is increased.
  • the en bloc and complete resection rate (R0) is increased in lesions with submucosal invasion.
  • the pooled benign polyps rate decreased in lesions referred to surgery.
  • the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion increased in lesions treated with advanced en bloc procedures (ESD, TAMIS, fullthickness resection).
  • the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion decreased in lesions treated with piecemeal endoscopic resection.
  • the diagnostic accuracy for predicting deep submucosal invasion in a test with pictures after participating is increased.
Read the detailed description

Non-pharmacological multi-centre randomised controlled trial. Gastroenterologists who have performed > 300 colonoscopies without supervision and who have finished/will finish the residency in Gastroenterology between 2014 and 2023 will be invited to participate. Gastroenterologists participating in the study will register the optical diagnosis, endoscopic lesions' characteristics, histology and clinical outcomes of consecutive non-pedunculated lesions ≥ 20 mm found in routine colonoscopies during a whole year. Participants allocated in the intervention group will receive a learning module after six months. Those assigned in the control group will not receive any learning module (they will be offered to do it at the end of the study). Pooled sensitivity and diagnostic accuracy of optical diagnosis for predicting deep submucosal invasion, and clinical outcomes in routine colonoscopies will be compared in both groups. Diagnostic accuracy for predicting deep submucosal invasion in a test with pictures before and after participating will also be compared.

What participants receive

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

  • E-learning moduleOther

    The intervention is a structured e-learning module on a web-based platform (www.trainingopticaldiagnosis.com) that consists of:

    • 10 modules, including theoretical knowledge and multiple exercises.
    • 2 seminars with a tutor (after Module 5 and Module 10)
    • feedback from the tutor on three cases recorded by the participant.
    • 20-images test before and after the content described above (10 Modules, 2 seminars with tutors and feedback on three cases)

    All the Gastroenterologists participating in the study will predict deep submucosal invasion in their routine colonoscopies and will register clinical outcomes during 12 months. The randomisation and intervention will be conducted 6 months after starting to predict deep submucosal invasion and registering clinical outcomes.

Where is the study taking place?

The record lists 12 sites in Spain, United States, Japan, United Kingdom. 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?

Results are not available in the source record.

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

Contact Anna Arnau, PhD (+34938759300 ext. 3414, aarnau@althaia.cat), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pooled sensitivity of endoscopic optical diagnosis for predicting deep submucosal invasion in routine colonoscopies (time frame: immediately after the colonoscopy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05663788, which also lists 4 linked publications.

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 7 Feb 2024.
