Colonoscopy quality studies have mostly focused on neoplasia detection, which is straightforward to assess. Conversely, incomplete polyp resection occurs in practice and contributes to postcolonoscopy colorectal cancer (CRC), but its prevalence and progression to significant metachronous neoplasia are difficult to measure.
This study included over 1000 patients (mean age, 62; 70% men) who underwent resection of a 10–20 mm neoplastic colorectal polyp between 2000 and 2012 and then had surveillance colonoscopy within 5 years. Incomplete polyp resection, new polyp formation, and detection of previously missed neoplasia were assumed to be the contributors to metachronous neoplasia in a colon segment. The risk for metachronous neoplasia due to in…
