RESUMO
BACKGROUND: Children who experience alkaline injury are at risk for the development of esophageal strictures and the need for esophageal dilations. OBJECTIVE: We aimed to assess predictors for a higher number of esophageal dilatations in children following alkali ingestion. METHODS: Single-center retrospective cohort study including children who underwent esophagogastroduodenoscopy (EGD) after alkali ingestion. Possible predictive factors for the need for esophageal dilatations were evaluated. RESULTS: A total of 34 patients were included, and 19 were female (55.9%). The median age at the time of the accidents was 20.6 months (IQR 15-30.7). All alkali ingestions were accidental, in all cases involving liquid products, and most (24/34; 70%) occurred at the child's home. Homemade liquid soap was the agent in half of the cases. The most frequently reported symptom at presentation was vomiting (22/34, 64.7%). The median follow-up time was 3.2 years (IQR 1.1-7.4). On follow-up, the median number of esophageal dilatations required for these patients was 12.5 (IQR 0-34). Among demographic factors, male gender (P=0.04), ingestion of homemade products (P<0.01), and accidents happening outside of the household environment (P=0.02) were associated with a greater number of esophageal dilations on follow-up. An endoscopic classification Zargar of 2B or higher (P=0.03), the presence of stricture at the time of the second EGD (P=0.01), and gastroesophageal reflux disease (GERD) as a late complication (P=0.01) were also associated with a greater number of esophageal dilations on long term follow-up. CONCLUSION: Beyond the endoscopic classification severity - a well-known risk factor for the strictures after alkali ingestions, we found that male gender, accidents with homemade products, and accidents occurring outside the household environment were significantly associated with a greater number of esophageal dilatations in the long-term follow-up of children following alkali ingestion.

RESUMO Contexto: Crianças que sofrem lesões cáusticas correm alto risco de desenvolver estenose esofágica e necessidade de dilatações esofágicas. Objetivo: Objetivamos avaliar preditores de necessidade de maior número de dilatações esofágicas em crianças, após uma ingestão cáustica. Métodos: Estudo de coorte retrospectivo de centro único incluindo crianças submetidas a esofagogastroduodenoscopia (EGD) após ingestão cáustica. Foram avaliados possíveis fatores preditivos para a necessidade de dilatações esofágicas. Resultados: Foram incluídos 34 pacientes, 19 do sexo feminino (55,9%). A idade mediana no momento dos acidentes foi de 20,6 meses (IQR 15-30,7). Todas as ingestões cáusticas foram incidentais, de substâncias líquidas, e a maioria dos acidentes (24/34; 70%) ocorreu no domicílio da criança. Em metade dos casos, a substância ingerida foi um sabão caseiro. O sintoma mais reportado na apresentação foi vômito (22/34 -64,7%). O tempo médio de acompanhamento foi de 3,2 anos (IQR 1,1- 7,4). No seguimento, o número médio de dilatações esofágicas necessárias foi de 12,5 (IQR 0-34). Entre os fatores demográficos, o sexo masculino (P=0,04), acidentes com produtos caseiros (P=<0,01) e a localização do acidente fora do ambiente domiciliar (P=0,02) foram associados a um maior número de dilatações esofágicas no seguimento. A classificação endoscópica Zargar 2B ou mais (P=0,03), a presença de estenose na segunda EGD (P=0,01) e a DRGE como complicação tardia (P=0,01) também se associaram a maior número de dilatações esofágicas no acompanhamento a longo prazo. Conclusão: Além da gravidade da classificação endoscópica - fator de risco bem conhecido para as estenoses após ingestão de cáusticos, observamos que o sexo masculino, os acidentes com produtos caseiros e os acidentes ocorridos fora do ambiente doméstico foram fatores significativamente associados a um maior número de dilatações esofágicas em acompanhamento em longo prazo de crianças após ingestão de soda cáustica.
