Preoperative enterocolitis is associated with poorer long-term bowel function after Soave-Boley endorectal pull-through for Hirschsprung's disease

Abstract

Background/purpose: The purpose of the investigation was to apply a semiquantitative scoring system for bowel function to patients who had undergone endorectal pull-through (ERPT) for Hirschsprung's disease (HD) and to use this to analyse the clinical factors relating to functional outcome.

Methods: The case note details of 63 patients undergoing ERPT for HD were reviewed. A questionnaire using a semiquantitative scoring system for 6 aspects of bowel function was sent to parents of 55 patients. The total functional score (TFS) for each patient was calculated, and a statistical analysis was performed to determine which clinical factors were significantly related to bowel functional outcome.

Results: Fifty (91%) of the parents returned the questionnaire. TFS was "good" in 45%, "fair" in 33% and "poor" in 22%. There was a statistically significant difference in the scores of those who had preoperative Hirschsprung's associated enterocolitis (HAEC) TFS = 8.0 and those who did not, TFS 12.7 (P <.01) The sex of the patient, length of aganglionic segment, timing of ERPT (early/late), staging of ERPT (1 or 2), presence/absence of anastomotic stricture, and presence or absence of Down's syndrome did not statistically significantly affect TFS.

Conclusions: Preoperative HAEC was the most important factor in relation to functional outcome after ERPT for HD. The reason remains unclear.
