Risk of Metachronous Findings After Detection of Serrated Lesions and High-grade Dysplasia With Surveillance Delay
Sponsor: Centre hospitalier de l'Université de Montréal (CHUM)
Summary
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.
