What this Trial Is About
Colonoscopy is the cornerstone for colorectal cancer screening, diagnosis, and post-treatment surveillance. Procedural quality is influenced by patient anatomy, particularly variations in colonic configuration such as sigmoid redundancy, looping, and low-lying transverse colon. These features prolong insertion time, increase patient discomfort, and elevate physician workload. Evidence suggests that prior CT imaging can provide objective and individualized information on colonic anatomy-such as redundancy, angulation, and tortuosity-potentially predicting procedural difficulty. However, existing studies are mainly retrospective or descriptive, lacking prospective randomized evidence on clinical utility. This single-blind, randomized controlled trial evaluates whether image-assisted colonoscope insertion, based on pre-existing abdominal/pelvic CT scans, can improve cecal intubation time, enhance patient experience, reduce operator workload, and improve overall examination quality compared with standard colonoscopy.
