As reported in the media, The Children’s Hospital of Philadelphia’s (CHOP’s) Division of Gastroenterology is conducting an FDA-funded study to determine if components of PEG 3350 are absorbed into children’s blood. PEG 3350 is contained in certain over-the-counter medications commonly prescribed by physicians to treat children with constipation. The FDA has received reports from parents who are concerned that this medicine has caused neurobehavioral symptoms in their children.

Hirschsprung Disease Risk Factor Study

Join our human research studies!
We believe that both genetic and non-genetic factors cause Hirschsprung disease. We hope you will help us to identify the causes of Hirschsprung disease so that we can develop new prevention strategies.
We are currently enrolling children with Hirschsprung disease, their siblings and parents in our study. We need to enroll as many people as possible to have the greatest chance of success.
