[Long-term outcomes of ileal pouch-anal canal anastomosis in children with ulcerative colitis].

The present study investigated the long-term outcomes of restorative proctocolectomy in pediatric patients with ulcerative colitis (UC). We report a series of 25 patients who underwent total proctocolectomy with ileal pouch-anal canal anastomosis (IACA). Surgery was performed for medically intractable colitis and severe colitis in 14 and 11 patients, respectively. Early and late complications were observed in 6 (24%) and 14 (56%) patients, respectively. The long-term quality of life outcomes were satisfactory, including both bowel function and social function. Growth retardation was observed in 6 patients. Five patients exhibited catch-up growth and 3 patients overcame growth retardation. Patients with growth retardation tended to have a younger onset and longer duration of UC, as well as a longer duration and higher total dose of steroid use. In conclusion, the long-term outcomes of pediatric patients with UC undergoing IACA are satisfactory. Furthermore, to minimize the risk of growth retardation, surgery should be performed without delay.
