Abstract:
OBJECTIVE: Recent guidelines made recommendations for the management of gastroesophageal reflux in patients with esophageal atresia (EA). However, the timing for some diagnostic tests remained somehow unclear. This investigation studied the tests for gastroesophageal reflux in children aged one year old and children aged two or three. MATERIALS AND METHODS: Patients with EA who underwent Multichannel Intraluminal Impedance-pH monitoring (MII-pH) and endoscopy-histology were studied retrospectively. Patients aged one when the test was performed were the YO group and patients aged two or three years old formed the OL group. Substantially impaired MII-pH was defined as total number of reflux episodes >105 or >85 (depending on age), or reflux index >10%. Substantially impaired endoscopy was defined as erosive esophagitis or Barrett's esophagus. Substantially impaired histology was defined as moderate-severe esophagitis or Barrett's esophagus. Conventional parameters and substantially impaired values of the tests were compared. RESULTS: Twenty-four patients were studied. Twenty-three MII-pH were performed (12 in YO and 11 in OL): percentages of abnormal conventional parameters of MII-pH were not significantly different in both groups. Twenty endoscopies with biopsies were performed (7 in YO and 13 in OL): percentages of esophagitis were not significantly different. Interestingly, 26.9% of all the tests performed in YO were substantially impaired vs. 10.8% of all the tests in OL (χ2 = 2.7; p = 0.1). CONCLUSION: Considering the percentage of alarming results of diagnostic tests in the YO group it would be advisable that patients with EA undergo MII-pH and endoscopy-histology at one year of age. OBJETIVOS: Recientemente se han publicado recomendaciones para el manejo del reflujo gastroesofágico en pacientes con atresia de esófago (AE). Sin embargo, el momento de realización de algunas pruebas no está completamente aclarado. Esta investigación evalúa las pruebas para reflujo gastroesofágico en niños de 1 año y niños de 2-3 años. MATERIAL Y METODOS: Estudio retrospectivo de pacientes con AE sometidos a impedanciometría-phmetría (IMpH) y a endoscopia-histología. Los pacientes con 1 año en el momento de la prueba formaron el grupo MEN, y los pacientes con 2-3 años, el grupo MAY. Se consideró IMpH sustancialmente alterada aquella con un número total de reflujos >105 o >85 (según la edad), o un índice de reflujo >10%. La endoscopia se consideró sustancialmente alterada si presentaba esofagitis erosiva o esófago de Barrett. La histología se consideró sustancialmente alterada si presentaba esofagitis severa-moderada o esófago de Barrett. Se compararon los parámetros convencionales y los sustancialmente alterados. RESULTADOS: Se estudiaron 24 pacientes. Se realizaron 23 IMpH (12 en el grupo MEN y 11 en el MAY); los porcentajes de los parámetros convencionales patológicos no fueron estadísticamente diferentes en ambos grupos. Se realizaron 20 endoscopias (7 en el grupo MEN y 13 en el MAY); los porcentajes de esofagitis no fueron estadísticamente diferentes. El 26,9% de todas las pruebas en el grupo MEN resultaron sustancialmente alteradas, frente al 10,8% en el MAY (χ2 = 2,7; p = 0,1). CONCLUSION: Teniendo en cuenta el porcentaje de resultados alarmantes en el grupo MEN, sería recomendable realizar una IMpH y una endoscopia con biopsias a los pacientes con AE a la edad de un año.
