RESUMO

A gastrointestinal lipoma, though rare, is a mesencymal tumor of the large bowel, and the second most common benign colonic tumor detected after an adenomatous polyp. The lesion may be asymoptomatic when small and may be detected incidentally, usually during a colonoscopic examination for another purpose. Lipomas of the large bowel that are not causing symptoms probably need no treatment, as malignant transformation has not been documented. If the mass is large, it can cause pain, anal bleeding due to intussusception, bowel obstruction and diarrhea, and thus resection should be considered. Due to the risk of perforation, endoscopic resection of large colonic lipomas has been discouraged. However, large colonic lipomas can be removed safely by endoscopic resection with the use of an endoscopic ultrasonogram and submucosal injection to elevate the lesion.

RESUMO

Colonic lipomas represent mesenchymal origin tumors that are second most common benign colonic tumor after hyperplastic polyps and adenomatous polyps. The patho-genesis of them is not clear. Most patients are asymptomatic and the lesion is often detected incidentally at colonoscopy, operation, and autopsy. According to the size and the location of lipoma, it may cause intestinal obstruction, perforation, intussusception, and life-threatening bleeding. There have been many reports of small colonic lipomas removed by endoscopic resection. Giant lipoma which is greater than 2 cm in size has been associated with higher risk of perforation, thus it has been removed by surgery until now. We report a case of colonic giant lipoma inducing intussusception which could be removed by endoscopic resection.
