Dyssynergic defecation may aggravate constipation: results of mostly pediatric cases with congenital anorectal malformation

摘要

BACKGROUND: Most patients with congenital anorectal malformation suffer from mild chronic constipation. To date, it is unclear why a subgroup of patients develops a persistent form of constipation. Because dyssynergic defecation is a common cause of constipation in the general population, we hypothesized that the severe form of constipation may be caused by dyssynergic defecation.
