Purpose: Previous studies have reported decreased continence in patients undergoing transanal endorectal pull-through (TERP) for Hirschsprung's disease compared to the older transabdominal approach (TAA). To address this, we examined long-term stooling outcomes in a large, multicenter cohort of patients undergoing either TERP or TAA.
Methods: Data were collected from 5 large pediatric institutions. Patient families were surveyed using a stooling score system (0-40, best to worst total score). Inclusion criteria included patients older than 3 years and those who had more than 6 months of recovery after pull-through. Those with total colonic aganglionosis were excluded. Statistical analysis included univariate and multivariate linear regression (significance, P < .05).
Results: Two hundred eighty-one patients underwent TERP (192) or TAA (89). Interviews were completed in 149 (104 [52%] TERP vs 45 [52%] TAA). The TAA group had a significantly greater number of daily bowel movements for each respective postoperative year and experienced more early complications (3% vs 1% with >1 complication; P = .061) and late complications (19% vs 4% with >1 complication; P < .001). Although the TAA group had a higher mean enterocolitis score (3.3 +/- 0.4 vs 1.8 +/- 0.2; P < .001), this was not borne out by multivariate regression analysis (P = .276). Parental survey showed that there were no significant differences between procedures in mean total, continence, or stooling pattern scores.
Conclusion: Transanal endorectal pull-through was associated with fewer complications and fewer episodes of enterocolitis. In contrast to prior studies, TERP patients did not have a higher rate of incontinence. These results support use of TERP as an excellent surgical approach for children with Hirschsprung's disease.
