Abstract
Appendiceal intussusception is an uncommon type of intussusception with the incidence of 0.01% in children and adults. In many cases it was developed by secondary conditions, such as polyps, carcinoma or lymphoma. But some other cases was reduced after barium enema study and had none of initiating causes. Therefore, making an accurate diagnosis is important in providing the optimal treatment for the patient. We present an appendiceal intussusception spontaneously reduced after colonoscpic examination. A 61-year-old woman with indigestion, nausea and right lower quadrant abdominal tenderness was admitted for further evaluation and treatment. Colonoscopic exam revealed a invaginated appendix with normal appearing covring mucosa intraluminaly. Blind mucosal biopsies on the appendiceal orifice yielded mild inflammatory cell infiltration. Two days after the colonoscopic procedure, patient's abdominal symptoms and sign were disappeared. Abdominal CT scan revealed that appendiceal intussusception was spontaneously reduced and a few several reactive mesenteric lymphadenopathy was observed. The ultrasound scan revealed the appendiceal wall swelling. The patient was discharged after the relief of abdominal symptom without further treatment. (Korean J Gastrointest Endosc 2004;28:257261)
