ClinConnect Summary

This clinical trial is studying a new real-time system designed to help doctors accurately estimate the size of colorectal polyps during colonoscopy. Understanding the size of these polyps is important because larger polyps (especially those over 10 mm) can indicate a higher risk of advanced features or colorectal cancer. By measuring polyp size correctly, doctors can make better decisions about patient care, including how often patients need surveillance and what type of treatment may be necessary. The trial aims to improve the accuracy of these measurements, which could lead to earlier diagnoses and better outcomes for patients.

To participate in this trial, individuals must be 18 years or older and have undergone a colonoscopy for screening or investigation of symptoms. Those who are not eligible include individuals with certain medical conditions that could make colonoscopy unsafe or those who have serious health issues. If you join the trial, you will help researchers gather important information that could enhance how doctors assess and manage colorectal polyps in the future. The trial is not yet recruiting participants, so there will be more information available soon for those interested.
