Abstract
Purpose: Transanal single-stage endorectal pull-through (TERPT) procedure for patients with Hirschsprung disease (HD) has favorable outcomes, with a lower complication rate. Nevertheless, various degrees of bowel dysfunction and fecal incontinence can persist for a long time in some patients. The aim of this study was to assess the mid- and long-term outcomes of TERPT performed during the infantile period after the completion of toilet training.

Methods: We retrospectively reviewed 82 patients aged ¡Ã4 years who underwent TERPT during the infantile period after the pathological diagnosis of HD between 2001 and 2013. Functional outcomes were investigated according to the answers of the Bowel Function Score (BFS) questionnaire, a previously validated 7-item questionnaire about bowel habits. Normal values were obtained in a previous study on BFS for children in Western countries, and a one-sample t-test was used for statistical analysis.

Results: Overall, BFS was similar in all investigated age groups. On comparing fecal soiling and social problems between the HD and normal populations, a lower score at an early age in patients with HD was noted; however, the scores became similar when the patients were 7 years of age. Stool frequency decreased continuously but was not significantly different between the 2 groups.

Conclusion: The functional outcomes of TERPT performed during the infantile period, after completing toilet training, were similar to that of the normal population. In most cases, uncomfortable symptoms were diminished and functions improved with age.
