Y1 - 2010 N1 - T2 - Pediatric Practice: Gastroenterology AB - Gastrointestinal (GI) motility disorders (GMDs) are represented by a spectrum of conditions that range from benign prevalent disorders (gastroesophageal reflux (GER) and childhood constipation) to more rare and severe entities (chronic intestinal pseudo-obstruction (CIP) and Hirschsprung’s disease). Altered GI motility adds considerable co-morbidity to structural anomalies such as intestinal atresia, stenosis, or gastroschisis. Pediatric GMDs are classified according to the results of GI motility testing. It is likely that with advanced methods of studying the brain–gut axis, classification of these disorders will eventually be based on pathophysiology. Within the pediatric population, GMDs are also known to be either congenital or acquired, depending on the presence or absence of symptoms at birth.1,2 Congenital disorders usually cause symptoms within the first 2 months of life and can be sporadic or familial. Acquired motility disorders present later in life and can be secondary to a variety of insults including infections and adverse reactions to medications.3 Within the pediatric population, GMDs account for up to 15% of all intestinal failures.
