Plain-language verified summary

Question

Wholemount of the colon of a 1-week-old Ednrb−/− rat.

Methods

Up until the time of weaning, 3 weeks after the rescue surgery, KO rats that had undergone surgery grew similarly to WT rats (Fig.

Scale or participants

Growth curves of Ednrb−/− and WT rats from the Ednrb colony, showing the effect of supplementation with an oral rehydration and energy solution.

Key findings

In Hirschsprung disease, there is failure of the enteric nervous system of the distal bowel to form during development.

Limitations and uncertainty

Patients with Hirschsprung disease lack enteric ganglia in the distal colon and propulsion of colorectal content is substantially impaired.
