Comparative review of functional outcomes post surgery for Hirschsprung's disease utilizing the paediatric incontinence and constipation scoring system.

PURPOSE

We aim to analyze differences in functional outcomes in children operated on for Hirschsprung's disease (HD) using the Paediatric incontinence/constipation scoring system (PICSS) validated in a normative group.

METHODS

A retrospective review of the records of all children operated on for HD between 1997 and 2010 was performed. Patients had either a Soave or transanal endorectal pull-through. Children with total colonic aganglionosis and Down's syndrome were excluded. Utilizing the PICSS children who scored below their age-specific lower limit 95 % confidence interval PICSS scores were considered to have incomplete continence or constipation. The rates of incomplete continence and constipation were compared between groups. Significance was set at p < 0.05.

RESULTS

PICSS analysis could be completed in 51 (Soave 35, transanal 16). The median age at interview was 71 months (range 6-191 months). The rate of incomplete continence was 75 % (n = 21) and 71 % (n = 10) for the Soave and transanal groups, respectively (p = 1.00). The constipation rate was 34 % (n = 12) and 25 % (n = 4) for the Soave and transanal groups, respectively (p = 0.74). The overall rates of incomplete continence and constipation rates were 74 and 31 %, respectively, compared with 14 and 10 %, respectively, when rates were calculated by review of records.

CONCLUSION

The PICSS is a sensitive tool for assessing functional outcome post HD surgery. The Soave and transanal procedures have similar functional outcomes.
