Description

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.

Interventions

Colonoscopy after bowel cleansing with 2D imaging device (Procedure)
participants will undergo colonoscopy examination using 2D imaging colonoscope to detect potential adenomas or polyps. The classification of the detected lession will be determined by the edoscopic diagnosis based on the JNET classification system or by the pathological diagnosis with tissues from biopsy or polypectomy.
