Postinfectious gastroparesis: a case series of three adolescent females.

Postinfectious gastroparesis (PIGP) is a subgroup of idiopathic gastroparesis rarely reported in adolescents. This study describes 3 adolescent females with severe PIGP, who each underwent extensive workup prior to referral to a pediatric gastroenterologist. PIGP may be an underrecognized disorder in pediatrics, particularly in adolescents, and if untreated, can lead to significant morbidity.
