The above features are suggestive of short segment Hirschsprung disease.
Hirschsprung disease is a condition resulted by aganglionosis (absence of ganglion cells) in the distal colon and rectum.
Among the 4 types, short segment is the most common type and accounts 75% of the cases.
Carefully performed contrast enema helps in diagnosis of the disease, as well as the length of involved bowel segment.
Full-thickness rectal biopsy is needed for confirmation.
