Trial summary

Adenoma detection rate (ADR) has been the most important quality indicator on colonoscopy because ADR was reversely related with CRC incidence and mortality. Several image enhanced technologies, such as narrow-band imaging (NBI) or linked colour imaging (LCI) had been proved to have ability to increase the ADR. Read more about this study

About this study

Official title: Comparison of Adenoma Detection Rate Between Conventional Colonoscopy and 3D Colonoscopy: a Randomized Controlled Trial

Adenoma detection rate (ADR) has been the most important quality indicator on colonoscopy because ADR was reversely related with CRC incidence and mortality. Several image enhanced technologies, such as narrow-band imaging (NBI) or linked colour imaging (LCI) had been proved to have ability to increase the ADR. 3D techonology, however, has not been validated on colonoscopy performance. Therefore, current study was to compare the ADR between new 3D colonoscopy and conventional 2D colonoscopy.

Read the detailed description

An accumulating body of evidence has shown that detection and resection of pre-cancerous adenoma by colonoscopy could effectively prevent colorectal cancer (CRC) and its related mortality. Among various colonoscopy quality indicators, such as cecal intubation rate, withdrawal time, and adenoma detection rate (ADR), ADR is the most important one and most closely associated with the subsequent risk of CRC. A recent study further demonstrated the improvement of ADR could reduce subsequent risk of CRC.

To be noted, among all colorectal neoplasm, non-polypoid lesions, such as flat or depressed lesions, carries higher likelihood to be overlooked during conventional colonoscopy and these overlooked lesions were the main etiology of post-colonoscopy colorectal cancer (PCCRC). Nowadays, several colonoscopy technologies had been developed to enhance the detection of colorectal adenoma such as using digital or dye-spray chromoendoscopy or add-on device such as Cap-assisted endoscopy. Among them, some had showed the potential to enhance the detection of non-polypoid lesion, for example, the next-generation NBI or iSCAN.

3D endoscopy is a new technology that using image processing technique to offer more information on tissue depth in comparison with conventional 2D endoscopy. The utility of 3D endoscopy on GI tract was mainly from upper GI tract and it was proved to enhance the diagnostic accuracy on superficial gastric tumors and shortened the procedure time during performing gastric endoscopic submucosal dissection(ESD). However, few is known that whether 3D colonoscopy could enhance the adenoma detection, especially for non-polypoid lesion detection, during colonoscopy examination. Therefore, this prospective, randomized control study is aim to demonstrate the efficacy of 3D colonoscopy on adenoma detection in comparison with conventional 2D colonoscopy.

Study groupRoleWhat they receive
3D colonoscopyExperimentalColonoscopy insertion under regular method. After reaching cecum, the subjects will be randomized into 3D or conventional colonoscopy. Subjects in 3D colonoscopy arm: Colonoscopist will switch the image to 3D imaging form and wearing special glasses to enhance the 3D imaging. The 3D mode will be maintained during the whole colonoscopy withdrawal. When encountering suspicious neoplasm, the colonoscopist can use any image-enhancing technique (such as NBI or indigo carmine dye) to assist the diagnosis and use standard resection procedure (such as polypectomy) to complete lesion resection if necessary. The procedure time, withdrawal time, adenoma detection rate will be recorded during the colonoscopy. The pathology specimen will be sent for histology examination and any adverse event after colonoscopy (such as bleeding or perforation) will be recorded after routine surveillance.

What is being measured

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

  1. Adenoma detection rate

    The number of subjects with at least one adenomatous polyp found during the colonoscopy

    Measured: 1 week

Secondary outcomes (4)
  1. Proximal adenoma detection rate

    The number of subjects with at least one adenomatous polyp found at proximal colon ( cecum, ascending colon and hepatic flexure) during the colonoscopy

    Measured: 1 weeks

  2. Sessile serrated adenoma detection rate

    The number of subjects with at least one sessile serrated adenomatous polyp found during the colonoscopy

    Measured: 1 week

  3. Adenoma per colonoscopy (APC)

    Average adenomatous polyps number found in each colonoscopy

    Measured: 1 week

  4. Flat adenoma detection rate

    The number of subjects with at least one flat adenomatous polyp found during the colonoscopy

    Measured: 1 week

Questions about this trial

What is this clinical trial studying?

A study testing 3D colonoscopy in people with Colorectal Neoplasms and Colorectal Cancer, run by National Taiwan University Hospital at 1 site in Taiwan.

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 5 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 19 Sep 2024. 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 Taiwan. 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?

Adenoma detection rate (time frame: 1 week). 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 19 Sep 2024.
