In medicine, colonoscopy is a "endoscopic examination, therapy or surgery of the luminal surface of the colon."[1]
Accuracy
Colonosopy is not perfect and may miss colonic polyps that could lead to colorectal cancer.[2] Withdrawing the colonoscopy too fast may cause missing of important abnormalities.[3]
Adverse effects
In a study of 2531 volunteers 50 years of age or older undergoing colonoscopy:[4]
- hematochezia occured after snare polypectomy in one patient and required 2 days of hospitalization
- ''Escherichia coli'' bacteremia occur in one patient and required hospitalization
