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.\n\nEvidence 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.\n\nThis single-blind, randomized controlled trial evaluates whether image-assisted colonoscope insertion, based on pre-existing abdominal\u002Fpelvic CT scans, can improve cecal intubation time, enhance patient experience, reduce operator workload, and improve overall examination quality compared with standard colonoscopy.",[27,28,29,30],"Colorectal Cancer Screening","Colonic Polyps\u002FColonoscopy\u002FColorectal Neoplasms","Difficult Colonoscopy","Colonoscopy-Related Discomfort",[32,33,34,35,36],"Colonoscopy","Cecal Intubation Time","Looping","Image-Assisted Colonoscopy","Personalized Colonoscopy","RECRUITING","2026-04-14",{"date":40,"type":41},"2026-04-21","ACTUAL",{"date":43,"type":41},"2025-12-09",{"date":45,"type":21},"2026-05-28",{"name":47,"class":48},"DONG WU","OTHER",""]
