A woman in her 70s was diagnosed with a 4 cm-diameter colonic lipoma following a hematochezia. Because it is generally reported that colonic lipomas larger than 4 cm in diameter cause intestinal accumulation about 70% of the time, prophylactic resection is desirable. Although surgery is often performed when the colonic lipoma is larger than 4 cm in diameter, we carried out endoscopic treatment to remove the tumor in consideration of the patient's wishes. Endoscopic Submucosal Dissection (ESD) was originally planned, but ESD was deemed too risky and switched to ischemic treatment. The SB knife Jr2®, one of the scissor-type knives, is very safe and effective for endoscopic treatment of movable colonic lipomas. Ischemic treatment with a snare is also effective in treating lipomas.
