What this trial is testing

Condition(s) listed: IBD (Inflammatory Bowel Disease), Colonoscopy and Colonoscopy: Bowel Preparation. This is an observational study: researchers collect information (for example questionnaires, samples, or scans) but the study does not assign a treatment.

Who can join

Ages 18 to 75
Any sex
Healthy volunteers accepted

Some of the main requirements, copied from the record:

Patients aged 18 years or older, of any gender, scheduled for colonoscopy;
Patients diagnosed with Inflammatory Bowel Disease (IBD) according to the 2023 edition of the Guidelines for the Diagnosis and Treatment of Inflammatory Bowel Disease;
Voluntary participation in this study and provision of signed informed consent.

There are also 10 reasons someone might not be able to join (exclusion criteria). Only the trial team can confirm whether you qualify.

What's involved

About 1000 participants are expected to take part.
Start date: 2025-12-08.
Main results expected around 2026-10-01 (estimate from the record).
1 study site listed (1 marked recruiting) in China.

Main thing being measured

adequate bowel preparation rate (The adequate bowel preparation rate can be assessed immediately upon completion of colonoscopy)

In the researchers’ words

The primary objectives of this project are twofold. On the one hand, it aims to investigate the current status of bowel preparation protocols and their quality in IBD patients undergoing colonoscopy, particularly focusing on the implementation of these protocols across hospitals following the release of the 2023 bowel preparation guidelines.

Interventions

Standard Pre-colonoscopy Bowel Preparation Protocol (Other)
This involves standard clinical instructions including a low-residue diet prior to colonoscopy and the administration of bowel cleansing agents (e.g., Polyethylene Glycol) according to the split-dose regimen as per each participating center's routine practice. The timing, dosage, and specific agent used follow existing institutional guidelines.
