Male, age 15 with gastrointestinal dysmotility and chronic constipation

Date of Report

Jan 03, 2019


The participant began experiencing chronic constipation at age 6. Testing identified GI issues (gastrointestinal dysmotility) and he was treated with a cecostomy tube at 8 years old. Since then, his constipation has gotten progressively worse and he has not been able to be weaned off of the cecostomy tube. Some of his other symptoms include asthma and a benign brain mass (Rathke’s cleft cyst). With the exception of these symptoms, the participant has had normal development.
