ABSTRACT

Objective To explore the stooling patterns and colonic motility after transanal onestage pull through operation for Hirschsprung' s disease in children. Methods Follow-up of more than 6 mos was obtained in all 58 children. The stooling pattern was investigated through questionnaire. Barium enema and colonic transit time with the simplified radio opaque markers were performed. Results Frequent stools was found in 4 cases, postoperative soiling in 9, constipation in 5 and Hirschsprungassociated enterocolitis in 3. No patients suffered from postoperative incontinence. Barium enema showed normal shape of the colon in most children, the sigmoid loops decreased or disappeared and was believed to be related to the length of removed colonic segment. Defecography showed the anorectal angle was larger and fixed than that of preoperative and control group[(123?15)?vs. (85?8)?vs. (79?12)?,P 168 h, P 0. 05 ]. TCTT and RSTT in symptomatic group were significantly shorter [ (25?6) h vs. (29?8) h,P
