Surgical outcomes for patients with rectosigmoid hirschsprung disease who underwent transanal endorectal pull-through after 1 year of age.

PURPOSE

This study aimed to compare the differences in postoperative complications and long-term bowel function outcomes between patients with rectosigmoid Hirschsprung disease (HD) who underwent transanal endorectal pull-through (TEPT) beyond infancy (age> 1 year of age) and those during infancy (≤ 1 year of age).

METHODS

All patients with rectosigmoid HD at Beijing Children's Hospital between January 2011 and December 2020 were analyzed retrospectively. They were divided into two groups based on age at TEPT: group A was defined as patients who performed TEPT beyond infancy (age>1 year of age), and group B as patients who performed TEPT during infancy (age ≤ 1 year of age). Clinical details were collected from medical records. Bowel function outcomes were assessed by the Rintala questionnaire (age ≥ 4 years).

RESULTS

A total of 339 patients were included: 216 (63.7%) who operated with TEPT beyond infancy (group A) and 123 (36.3%) during infancy (group B). Regarding postoperative complications, all patients suffering anastomosis leakage following TEPT (7/216, 3.2%) occurred in group A, and the rate of anastomosis leakage in group A was significantly higher than in group B (3.2% vs. 0.0%, p = 0.044). 228 patients (228/327, 69.7%) completed the Rintala questionnaire. There was no significant difference in long-term bowel function outcomes between the two groups.

CONCLUSION

Compared with patients who performed TEPT during infancy, those beyond infancy are more likely to suffer anastomosis leakage. however, the long-term bowel function outcomes seem comparable.
