Abdominal migraines: Variations in diagnosis and care between pediatric gastroenterologists and neurologists.

INTRODUCTION: Abdominal migraine (AM) is uncommon and understudied. Our objective was to investigate the diagnosis and treatment of children and adolescents with AM and compare with that of pediatric gastroenterologists and neurologists.

PATIENTS AND METHOD: All AM cases (1-18 years) from a USA hospital with diagnosis of abdominal migraine or its variants (ICD-9 346.2 or IC-10 G43.D, G43.D0, G43.D1) between 2011 and 2017 were reviewed. Information on diagnosis, interval from onset of symptoms, diagnostic criteria, diagnostic tests, treatment, and outcome were analyzed.

RESULTS: 69 medical records were identified. The mean age at diagnosis was 9.7 years, and 48% of patients were female. 50/69 (72.4%) patients were exclusively treated by a pediatric gastroenterologist and 10/69 (14.5%) exclusively by a pediatric neurologist. 6/69 (8.7%) were initially evaluated by gas troenterology and referred to neurology, and 2/69 (2.9%) were initially evaluated by neurology and then referred to gastroenterology. 3/10 (30%) of the AM diagnosed by neurologists did no report ab dominal pain (AP), however, all diagnoses made by gastroenterologists did (p = 0.0035). 5/50 (10%) of the gastroenterology medical records and no neurology medical records mentioned Rome criteria.

CONCLUSIONS: Most of the children were diagnosed by pediatric gastroenterologists. Gastroenterolo gists rarely use the Rome criteria. Patients evaluated by neurologists are frequently diagnosed with AM even without AP (a criterion that is required for its diagnosis). Education is recommended for the correct and timely diagnosis of AM.
