In brief
Study examining the rare co-occurrence of Hirschsprung's disease and anorectal malformations in 2.5% of ARM cases. Early diagnostic indicators include bowel caliber changes during initial surgery and nonfunctioning stomas, with delayed diagnosis leading to complications including fecal fistulas and wound dehiscence.
Written by the GCMD Library team from the article.
Background and aim
The association of Hirschsprung's disease (HD) and anorectal malformation (ARM) is rare. The aim of this study is to highlight the frequency of this rare association and comorbidity that may be related to this association.
Patients and methods
Eleven cases out of four hundred forty six cases (2.5%) with ARM found to have HD association presented to Assiut University Children Hospital. All cases were diagnosed by complete clinical, radiological assessment and histopathological examination before correction. The evaluating parameters for those patients were the early warning signs for diagnosis, any unnecessary procedures done and any associated morbidity related to misdiagnosis of this association.
Results
Age at presentation of these eleven cases ranged from 2 days to 10 years. The diagnosis started early during neonatal period only in four cases either by change of bowel caliber or nonfunctioning stoma. In the remaining seven cases the diagnosis was delayed because of unsuspected association. Fecal fistula after closure of stoma and wound dehiscence followed by incisional hernia is evident associated comorbidity.
Conclusions
The incidence of HD in ARM population seems to be more common than its incidence in the general pediatric population. Caliber change of the bowel during the first operation or nonfunctioning stoma is early alarming sign for diagnoses of such association and should direct the attention for stomal biopsy.
