Colonic Intussusception Due to a Large Ascending Colon Lipoma

The document described a case of a 74-year-old man with a large lipoma in the ascending colon, which led to colonic intussusception, a rare complication. Initially presenting with abdominal pain and constipation, the patient underwent a colonoscopy revealing a large lipoma. Four months later, he experienced intermittent abdominal pain, and a CT scan confirmed intussusception. He underwent an open right hemicolectomy, and the pathology confirmed a 6-cm lipoma with ischemic changes. The study concluded that while colonic lipomas are usually asymptomatic, they can cause complications like intussusception, and surgical intervention may be necessary if symptoms arise. The incidence of colonic lipomas was reported to be 0.2-0.8%, and they are most commonly found in the ascending colon.
