Core Tip

Core Tip: Most colonic lipomas are asymptomatic and do not require removal. Mucosal lesions of colorectal lipomas are rarely observed, but removal is necessary if there is a precancerous mucosal lesion such as tubular adenoma or tubulovillous adenoma. Due to the poor electrical conductivity of fat, excessive electrical energy during the endoscopic removal can cause complications. Endoscopic submucosal dissection is a preferred technique to minimize electrical thermal injury, especially for large colonic lipomas with a mucosal lesion.
