title: [Bowel control after surgery for Hirschsprung's disease].
abstract: Bowel control was studied in 66 children operated by Ikeda's Z-shaped anastomosis for Hirschsprung's disease. At the age of 2 or 3 years, mild constipation was recognized in 16% of the children, incontinence in 12% and soiling in 28%. However, these disorders reduced as the patients grew up and finally over 7 years, constipation was seen in 8% of the patients, incontinence in 8% and soiling in 19%. According to barium enema, megarectum was seen in all constipated children but one, though slight megarectum was sometimes seen even in normal or incontinent children. Frequently, anal canal was wide and leakage of barium through the anus was seen in incontinent or soiling children. Anal canal pressure was high in constipated group, low in soiling group and the lowest in incontinent group. The appearance rate of rhythmical wave of anal canal and recto-anal reflex was the same among all groups. Our treatment of the constipation and incontinence is daily bowel movement using laxative, suppository or enema. For the incontinent patients without rectal sensation, biofeedback method or electrical stimulation is applied.
