Incidence and evolution of foreign body impaction in the upper gastrointestinal tract and its relationship with eosionophilic oesophagitis.

BACKGROUND: Foreign body impaction is a frequent indication of urgent endoscopy. One of the reasons for impaction is eosinophilic oesophagitis (EE). To analyze characteristics of oesophageal foreign body impactions and their relationship with eosinophilic oesophagitis. METHODS: In this retrospective study, urgent endoscopies in a tertiary care centre were analyzed. We included all urgent endoscopies due to bolus and foreign body impactions performed between September 1st 2018 and September 1st 2020. We reviewed clinical data of all patients who were diagnosed with EE and compared it to impactions that were due to other motives. The mean follow-up time was 18.7 months. RESULTS: 693 urgent endoscopy procedures were performed. 239 (34%) of these were due to foreign body ingestion. Mean age of the patients was 63 years old and 135 (63%) were men. EE was diagnosed in 36 (17%) patients. The factors associated with EE were age, to be younger than 50 years (OR, 7.3; 95% CI, 1.1-48.4; p=0.04), asthma/rhinitis/atopic dermatitis (OR, 8.9; 95% CI, 2.3-35.3; p=0.002), findings in the endoscopy as trachealization (OR, 9.7; 95% CI, 1.3-70.9; p=0.03) and psychotropic/calcium channel blocker drugs (OR, 0.09; 95% CI, 0.009-0.9; p=0.04). 15 (7%) patients died. In 6 of them death was impaction-related. None patients with EE died. CONCLUSIONS: Foreign body impaction in the upper gastrointestinal tract due to EE is a frequent cause of urgent endoscopy. Being under 50 years of age, having asthma/rhinitis/atopic dermatitis, trachealization on the oesophagus and not taking psychotropic/calcium channel blocker drugs are factors associated with the diagnosis of EE. Mortality in the follow-up of patients without EE is important.

Antecedentes: La impactación por cuerpos extraños es una indicación frecuente de endoscopia urgente. Una de las causas de impactación es la esofagitis eosinofílica. Nuestro objetivo es analizar las características de las impactaciones por cuerpos extraños en el esófago y su relación con la esofagitis eosinofílica.Métodos: En este estudio retrospectivo, se analizan todas las endoscopias urgentes realizadas por impactación de alimentos y cuerpos extraños en un hospital terciario entre el 1 de septiembre de 2018 y el 1 de septiembre de 2020. Se analizan las características clínicas de los pacientes diagnosticados de esofagitis eosinofílica y se comparan con las impactaciones debidas a otros motivos. El seguimiento medio fue de 18,7 meses.Resultados: Se realizaron 693 procedimientos de endoscopia urgentes; de ellos, 239 (34%) fueron por impactación por cuerpos extraños. La edad media fue de 63 años y 135 (63%) eran hombres; 36 (17%) de todos los pacientes con impactación fueron diagnosticados de esofagitis eosinofílica. Los factores asociados a ella fueron la edad, ser menor de 50 años (OR 7,3; IC 95%: 1,1-48,4; p=0,04), el antecedente de asma y/o rinitis y/o dermatitis atópica (OR 8,9; IC 95%: 2,3-35,3; p=0,002), los hallazgos endoscópicos como traquealización (OR 9,7; IC 95%: 1,3-70,9; p=0,03) y el consumo de fármacos psicotrópicos o antagonistas del calcio (OR 0,09; IC 95%: 0,009-0,9; p=0,04). Fallecieron 15 (7%) pacientes, todos sin esofagitis eosinofílica y en 6 el fallecimiento se relacionó con las impactaciones.Conclusiones:La impactación por cuerpos extraños en el tubo digestivo por esofagitis eosinofílica es una entidad frecuente en los servicios de endoscopia de urgencia.(AU)
