Abstract

Appendiceal intussusception is a rare disease with variable clinical findings, ranging from acute appendicitis to chronic recurrent abdominal pain or rectal bleeding. Occasionally, it is incidentally discovered with no symptoms. Because a preoperative diagnosis is difficult, it can be diagnosed either after surgery, in the case of acute appendicitis, or after a polypectomy, based on being mistaken for a polyp. During a colonoscopy, an appendiceal intussusception should be suspected if the appendiceal orifice is not observed at the cecum and there is a polypoid lesion at the location where the appendiceal orifice is expected. Treatments are usually determined according to preceding diseases. It is important that the colonoscopist avoid careless endoscopic removal by mistaking the intussusception for a polyp.
