Core Tip
Core tip: Endoscopic mucosal resection of colon polyps in a piecemeal fashion requires a first close follow-up to detect residual neoplasia. There are limited data on the optimal approach to reviewing polypectomy scars with narrow band imaging (NBI). In this prospective observational study, which randomized the initial technique for the detection of residual neoplasia, NBI was slightly more accurate than white light endoscopy. To improve the assessment of polypectomy scars, high-definition endoscopes with NBI should be the rule. However, biopsies are still required at the first follow-up, even if there are no macroscopically evident lesions.
