Clinico-pathological Features of Colonic Intussusception in Adults

children that are half a year to 2 years old, but intestinal or colonic invagination is a rare disease in adults. Intussusception in adult patients represents 1% of patients with bowel obstruction and 5% of all intussusception. It is usually primary and benign in children intussusception and pneumatic or hydrostatic reduction of the intussusception is enough to treat the condition in 80% of the patients. In contrast, 70% to 90% cases of intussusception in adults are secondary to a pathologic leading point that can be only identified intraoperatively, and surgery is necessary in most cases. Lesions that result in enteric intussusceptions are much different from colonic intussusceptions, and most colonic intussusceptions are caused by tumors, especially colon adenocarcinoma. The incidence of colonic intussusceptions is more rare than intestinal intussusception and is about one-third of intestine intussusception cases. Because of limited experience with such clinical entities and the various considerations involved in diagnosis and treatment, we report J Soc Colon Rectal Surgeon (Taiwan) March 2010
