Endoscopic ultrasound and endoscopic submucosal dissection with a multitraction device for a colonic submucosal lesion

With the increasing number of screening colonoscopies performed, better bowel preparation, and advancements in endoscopic image quality, asymptomatic small lesions are detected more frequently. Where there is suspicion of a submucosal neuroendocrine tumor (NET), en bloc resection is advised [1] because complete resection allows for better histopathological characterization and, in low risk cases, no endoscopic follow-up.
