Overview

Other diagnostic studies include rectal biopsy, barium enema, and anorectal manometry. A rectal biopsy, which will show an absence of ganglionic cells, is the gold standard confirmatory test for Hirschsprung's disease.^[1]^[2]

A rectal biopsy presenting the absence of ganglionic cells is the gold standard confirmatory test for Hirschsprung's disease.^[1]^[2]

Diagnostic Test	Findings
Rectal biopsy	Absence of ganglionic cells Presence of thickened, unmyelinated nerves Increased activity of acetylcholinesterase; absence of nicotinamide adenine dinucleotide phosphate (NADP) diaphorase-containing neurons Increase in the amount of acetylcholinesterase-containing nerve bundles
Enema	Contracted distal bowel and dilated proximal bowel with demonstration of the transition zone location in between
Anorectal manometry	Absent anal reflex and increased pressure
