Background
The aim of this study was to assess long-term outcomes of neonatal patients with Hirschsprung disease (HD) after single-stage transanal endorectal pull-through (TEPT) and to explore the predictive factors contributing to subnormal bowel function.
Methods
Patients aged > 3 years operated for HD with TEPT during neonatal period between 2007 and 2019 answered the bowel function score (BFS) questionnaire. The patients were retrospectively divided into two groups according to whether they had normal bowel function. The clinical variables were compared between the subnormal and normal BFS groups. Univariate and multivariable logistic regression analysis were performed to identify the predictive factors contributing to subnormal bowel function.
Results
A total of 160 children (71.7%) were included in this study, with mean follow-up time of 7.3 years (range 3.0–15.1 years). The level of aganglionosis were determined to be the short-segment (124/160, 77.5%), long-segment (33/160, 20.6%), and TCA (3/160, 1.9%). One hundred and thirty-four patients (83.8%) had a BFS ≥ 17, and 26 patients (16.2%) with subnormal bowel function (BFS < 17). Univariate and multivariate logistic regression analysis showed that level of aganglionosis with long-segment or TCA and postoperative hospital stay > 8.5 days were independent risk factors with OR of 3.213 (1.252, 8.246) and 3.813 (1.371, 10.606) for subnormal BFS, respectively.
Conclusion
Most HD patients who underwent one-stage TEPT in the neonatal period have favorable long-term results, and the level of aganglionosis with long-segment or TCA and long postoperative hospital stay may be closely related to subnormal bowel function.
