congenital megacolonmedical dictionary

A congenital condition which results in an enlarged and poorly functioning colon due to abnormal intestinal motility. These patients are at risk for intestinal obstruction. Constipation, vomiting, abdominal distention, poor weight gain, a retarded growth are common. Treatment include the use of a temporary colostomy with later resection of the affected portion of bowel.

Symptoms are eliminated in up to 90% of patients after surgery. Outcomes are better with early intervention.
