surveillance colonoscopy
Follow-up colonoscopic examination performed after previous detection and removal of colorectal polyps or cancer.
Full Definition
A colonoscopic procedure performed to monitor patients who have previously had colorectal polyps removed or who have been treated for colorectal cancer. Unlike screening colonoscopy in average-risk individuals, surveillance colonoscopy follows established protocols based on the findings from prior examinations, such as the number, size, and histology of previous polyps. The timing of surveillance intervals is determined by professional guidelines and risk stratification, with intervals typically ranging from one to ten years. This type of examination is distinct from both screening and diagnostic colonoscopy in its purpose and scheduling.
Usage
Usage note: Distinguish clearly from screening colonoscopy in medical documentation.
