Indeterminate Colitis: A Distinctive Clinical Pattern of Inflammatory Bowel Disease in Children

Inflammatory bowel diseases such as Crohn disease and ulcerative colitis are frequently clinical conditions in children. Another clinical entity, indeterminate colitis, is considered a subgroup of pediatric inflammatory bowel disease. It is generally characterized by early onset in the first years of life, and clinical behavior is rapidly progressive to pancolitis. The definition of indeterminate colitis has changed over the years, but it is usually used to identify severe colitis with overlapping features of ulcerative colitis and Crohn disease. Ileal pouch-anal anastomosis is the surgical treatment of choice for patients with ulcerative colitis, but increased rates of complications have been found in indeterminate colitis. Therefore, it is better to be cautious in patients with indeterminate colitis who present with severe attacks and require surgery. Pediatrics 2008; 122: e1278-e1281
