Objective: This multicentric study aimed to evaluate the quality of life (QOL) in children with Hirschsprung's disease (HD). Methods: HD patients aged from 6 to 18 years and followed-up in 2 French pediatric surgery centers were included in this study. QOL was assessed using the HAQL questionnaires according to age (6–11 and 12–18), filled by patients and their parents (proxy reports) and correlated with initial disease characteristics, nutritional status, and functional score of Krickenbeck. Results: Sixty-three patients were included. The acquisition of satisfactory voluntary bowel movements was found in only 50% of the 6 to 11 years old and 68% of the teenagers. Seventy percentage of the children and 55% of teenagers had soiling issues. The overall HAQLproxy6--11 score was 528/700; best scores were found for “fecal continence” (94/100), “social functioning” (94/100), and “urinary continence” (92/100) whereas the worst scores were for “general well-being” (64/100) and “diurnal fecal continence” (58/100). The overall HAQLproxy12--16 score was 607/700; best scores were for “urinary continence” (96/100) and “social functioning” (93/100). In a multivariate analysis, soiling was the only factor significantly associated with low QOL (P = 0.03). Conclusions: Soiling remains frequent in children operated on for HD and negatively affects their QOL. Assessment and treatment of soiling should be the priority for medical teams in the follow-up of these children.< Réduire
