About this trial
The goal of this clinical trial is to learn if 3-dimensional (3D) imaging device works to identify patients with high risk adenomas during colonoscopy to guide proper follow-up strategy. It will also learn about the safety of 3-dimensional (3D) imaging device. The main questions it aims to answer are:
Does 3-dimensional (3D) imaging device improve the identification of patients with high risk adenomas? What adverse events do participants experience during colonoscopy? Researchers will compare 3-dimensional (3D) imaging device to traditional 2-dimensional (2D) imaging device to see if 3-dimensional (3D) imaging device works to improve high risk adenoma identification.
Participants will:
Undertake colonoscopy examination using 3-dimensional (3D) imaging device or 2-dimensional (2D) imaging device. Be followed-up to 30 days to record potential colonoscopy-relevant adverse events.
