[Value of the assay of cholinesterase activity in superficial biopsies of the rectum in the diagnosis of Hirschsprung's disease].
Cholinesterase activity have been estimated in rectal biopsies of 19 children with Hirschsprung's disease and 80 normal children. A high level of acetyl-cholinesterase is a strong argument for the diagnosis of aganglionosis. However the ratio acetylcholinesterase over butyrylcholinesterase seems to be a better sign allowing a right diagnosis in 99% of the cases.
