Core Tip

Core Tip: The present study is the most extensive meta-analysis evaluating the surgical, histological, and oncological outcomes of endoscopic submucosal dissection (ESD) in comparison to endoscopic mucosal resection (EMR) in the treatment of colorectal polyps. Our analysis also showed the increased proficiency in performing ESD and EMR in Japan as compared to the rest of the world.
