While effective and far less invasive then surgery, colorectal ESD carries a perforation risk of approximately 5%. That rate is high in comparison with other conventional treatments such as snare polypectomy or endoscopic mucosal resection (EMR). In this paper, we report on a case of pneumoretroperitoneum, pneumomediastinum and subcutaneous emphysema which occurred following perforation during ESD.
