Background: Esophageal stricture is one of the most important complication of the caustic ingestion. Objective: The aim of this study was to evaluate complications of balloon dilatation among children with esophageal stenosis. Material and methods: In this retrospective study 82 children were included. Children who underwent balloon dilatation for esophageal stenosis were included in our study. Duration of study was 14 year starting from 2001. Mean age of the cases was 3.95±0.4 year (Min: 15 days, Max: 14 year). Chart review and telephone calling were the methods of data collection. Data was analyzed using SPSS. Results: In this study, 47% of the patients were male and 53% of the cases were female. Caustic ingestion (33.7%) was the most common etiology for the esophageal stricture. Vomiting (87.8%) was the most common presenting symptom. Among our cases, 76.8% had no compliant after esophageal dilatation. Chest pain was the most common compliant after esophageal dilatation. Response rate was similar among boys and girls. Toddler age had the best treatment response after esophageal dilatation. Conclusion: Among our cases, 76.8% had no post procedural compliant after esophageal dilatation. Esophageal perforation was seen in 4.9% of the cases. Chest pain was the most common post dilatation complication.

Antecedentes: La estenosis esofágica es una de las más importantes complicaciones de la ingesta de caústicos. Objetivo: El objetivo del estudio fue evaluar las complicaciones de la dilatación endoscópica con balón en niños con estenosis esofágica. Material y métodos: En este estudio retrospectivo se incluyeron 82 niños. Se incluyeron todos los niños que se sometieron a una dilatación endoscópica con balón por estenosis esofágica. La duración del estudio fue 14 años iniciando en el año 2001. La edad media de los pacientes fue 3,95 +/- 0,4 años (Min. 15 días, Máx. 14 años). La recolección de datos se realizó revisando las historias clínicas y con llamadas telefónicas. Los datos se analizaron con el Sistema SPSS. Resultados: En este estudio, 47% de los casos fueron varones y 53% fueron mujeres. La ingesta de caústicos fue la causa más frecuente de estenosis esofágica (33,7%). El síntoma más común fueron los vómitos (87,8%). Entre nuestros casos, 76,8% no presentaron molestias luego de la dilatación esofágica. El dolor torácico fue la molestia más común luego de la dilatación esofágica. La tasa de respuesta al tratamiento fue similar entre hombres y mujeres. Los niños pequeños tuvieron la mejor respuesta al tratamiento luego de la dilatación esofágica. Conclusiones: Entre nuestros casos, 76,8% no presentaron molestias luego de la dilatación esofágica. La perforación esofágica se presentó en 4,9% de los casos. El dolor torácico fue la complicación más común posterior a la dilatación.

ContextoA peritonite bacteriana espontânea é definida como uma infecção do fluido ascítico sem evidente origem intra-abdominal cirurgicamente tratável. A peritonite bacteriana espontânea é uma das complicações graves em pacientes com cirrose e ascite. Sem tratamento antibiótico precoce, esta complicação é associada com alta taxa de mortalidade. Portanto, o diagnóstico precoce e tratamento de peritonite bacteriana espontânea são necessários para a sobrevivência. O reagente de esterase de leucócitos pode rapidamente diagnosticar a peritonite bacteriana espontânea.ObjetivoEste estudo teve como objetivo descobrir a acurácia diagnóstica do teste com tiras de esterase de leucócitos para o diagnóstico de peritonite bacteriana espontânea.MétodosUm estudo transversal hospitalar unicêntrico foi realizado entre julho de 2013 e agosto de 2014 em crianças com cirrose hepática e ascite que foram admitidas no Departamento de Gastroenterologia Pediátrica no Hospital de Nemazee afiliado à Universidade de Ciencias Médicas de Shiraz (Irã). Todos os pacientes foram submetidos a paracentese abdominal, e o líquido ascítico foi processado para contagem de células, teste de tira de reagente de esterase de leucócitos (Combiscreen SL10) e cultura. Peritonite bacteriana espontânea foi definida como tendo uma contagem de polimorfonucleares (PMN ≥250/m3) no líquido ascítico. Sensibilidade, especificidade, valor preditivo positivo negativo do teste de esterase de leucócitos foram calculados de acordo com a fórmula.ResultadosForam analisados um total de 150 amostras de líquido ascítico de pacientes cirróticos; (53,2%) eram do sexo masculino e sua média de idade (4,33±1,88 anos). A atresia biliar (n=44, 29,4%) e hepatite neonatal idiopática (n=29, 19,3%) foram as etiologias mais frequentes de cirrose. Além disso, dor abdominal (68,6%) e distensão (64%) foram as queixas mais comuns de apresentação. De todos os casos, 41 (27,35%) foram diagnosticados com peritonite bacteriana espontânea (PMN ≥250/mm3). A sensibilidade e especificidade do teste de reagente de esterase de leucócitos segundo PMN ≥250mm3 foi de 87,80% e 91,74% e, para os resultados de cultura de líquido ascítico, de 88,23% e 77,44%. Valor preditivo positivo e valor preditivo negativo do teste em PMN ≥250mm3 foi de 80% e 95,23% e em casos com cultura positiva 33,33% e 98,09%, respectivamente. A eficiência do teste de reagente esterase de leucócitos no diagnóstico de peritonite bacteriana espontânea, de acordo com resultados de ≥250mm3 e cultura PMN, foi de 90,66% e 78,66%.ConclusãoO teste de tiras de esterase de leucócitos pode ser usado como um teste rápido para diagnóstico de peritonite bacteriana espontânea, devido a sua alta validade diagnóstica.

BackgroundSpontaneous bacterial peritonitis is defined as an ascetic fluid infection without an evident intra-abdominal surgically treatable source. Spontaneous bacterial peritonitis is one of the severe complications in patients with cirrhosis and ascites. Without early antibiotic treatment, this complication is associated with high mortality rate; therefore, early diagnosis and treatment of spontaneous bacterial peritonitis is necessary for survival. Leukocyte esterase reagent can rapidly diagnose the spontaneous bacterial peritonitis.ObjectiveThis study aimed to find out the diagnostic accuracy of leukocyte esterase dipstick test for the diagnosis of spontaneous bacterial peritonitis.MethodsA single centered hospital-based cross-sectional study was conducted during July 2013 to August 2014 on children with cirrhotic liver disease and ascites who were admitted in the Department of Pediatric Gastroenterology in Nemazee Hospital affiliated to Shiraz University of Medical Sciences (Iran). All patients underwent abdominal paracentesis, and the ascitic fluid was processed for cell count, leukocyte esterase reagent strip test (Combiscreen SL10) and culture. Spontaneous bacterial peritonitis was defined as having a polymorphonuclear count (PMN ≥250/m3) in ascitic fluid. Sensitivity, specificity, positive predictive value and negative predictive value of leukocyte esterase test were calculated according to the formula.ResultsTotally, 150 ascitic fluid sample of cirrhotic male patients (53.2%) and their mean age (4.33±1.88 years) were analyzed. Biliary atresia (n=44, 29.4%) and idiopathic neonatal hepatitis (n=29, 19.3%) were the most frequent etiology of cirrhosis. Also, abdominal pain (68.6%) and distension (64%) were the most common presenting complaint. Of all cases, 41patients (27.35%) were diagnosed to have spontaneous bacterial peritonitis (PMN ≥250/mm3). Sensitivity and specificity of leukocyte esterase reagent test according to PMNs ≥250mm3 were 87.80% and 91.74%, also on ascitic fluid culture results were 88.23% and 77.44%. Positive predictive value and negative predictive value of this test in PMNs ≥250mm3 were 80% and 95.23% and in cases with positive culture 33.33% and 98.09% were obtained, respectively. Efficiency of leukocyte esterase reagent test in diagnosing spontaneous bacterial peritonitis, according to PMNs ≥250mm3 and culture results were 90.66% and 78.66%.ConclusionThe leukocyte esterase strip test may be used as rapid test for diagnosis of spontaneous bacterial peritonitis due to its high diagnostic validity.
