عملکرد بالا ضایعات همزمان در بیماران مراجعه کننده به تومورهای کولورکتال گسترش گسترده جانبی

There is a very high prevalence of synchronous lesions, including other large and advanced synchronous lesions, in patients with flat or sessile conventional adenomas and serrated colorectal polyps. Patients with LLSTs in the colon need detailed clearing of the rest of the colon. Patients referred for endoscopic resection of serrated lesions ≥ 20 mm have a very high prevalence of serrated polyposis. This study has potential implications for further stratification of high-risk patient groups in postpolypectomy surveillance guidelines.
