Risk of Metachronous Findings After Detection of Serrated Lesions and High-grade Dysplasia With Surveillance Delay (NCT05355363)
🩺 Plain-English Summary (8th-Grade Level)
The primary aim of this study is to determine the rate of total metachronous advanced neoplasia (TMAN) detection after index detection of serrated lesions (SL) \[sessile serrated polyps (SSPs), traditional serrated adenomas (TSAs)\], and metachronous high-risk adenoma (HRA) after index detection of high-grade dysplasia (HGD). We will use the database of patients diagnosed with SL or HGD at index colonoscopy with a delay in surveillance and determine the risk of advanced lesions (especially high-risk lesion and CRC detection) of these delayed colonoscopies. The aim is to determine the effects of breach of continuity of care in these patients.
