The value of the ileoanal pull-through operation in the surgical treatment of children with ulcerative colitis is shown by this 10-year postoperative follow-up study of 6 patients. The results are based on a questionnaire and the performance of ileoscopic and histological follow-up examinations. In 5 of the 6 children (now adults), normal continence was present and there were no complaints. Postoperative difficulties in a girl now 17 years of age are attributed to an incorrect initial diagnosis.
