Summary

The goal of this clinical trial is to learn if 3-dimensional (3D) imaging device works to correctly classify colon polyps and adenomas during colonoscopy to guide the selection of proper treatment procedures. 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 correct classification as well as size and depth evaluation of polyps and adenomas during colonoscopy using pathology as gold standard? What adverse events do participants experience during colonoscopy and polypectomy?

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 classification and evaluation accuracy.

Participants will:

Undertake colonoscopy examination and polypectomy 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.
