Core Tip

Core Tip: Various traction devices were developed to overcome the challenges faced in endoscopic submucosal dissection (ESD). A multicenter randomized controlled trial in Japan compared the conventional ESD and traction device-assisted ESD (T-ESD) for colorectal tumors. Although T-ESD did not reduce ESD procedure time, the results of this study suggest that T-ESD is effective for larger lesions and nonexpert operators. A balloon-assisted endoscope and underwater ESD may be promising options and these methods can be combined with T-ESD.
