Recurrence which is a usual occurrence preceding colorectal EMR is managed by the device. It occurs within the year after the EMR (1). The present situation is such that, patients are subject to over-treatment on one hand and on the other, they could be released with unfinished treatment. A single view of endoscopy is not enough. However, recurrence is caught by follow-up endoscopy. Recurrence is also controlled at Follow up (1-3), owing to the Cellvizio benefit. At the resection site, it is subject to vivo depiction. Neoplasia can be identified consistently. The device also features a powerful inter-observer agreement and short learning curve.
