Objetivos. El objetivo de este estudio fue evaluar el riesgo clínico de la apendicitis con apendicolito y su importancia al elegir las estrategias terapéuticas.Métodos. Se analizó retrospectivamente a niños con diagnóstico de apendicitis aguda entre junio de 2011 y enero de 2017. Se dividió en un grupo con apendicolito(GA) y un grupo sin apendicolito (GSA) según la presencia o no de apendicolito durante la cirugía abierta. Se revisaron y compararon la presentación clínica, de laboratorios, los resultados de la tomografía computada y los cambios patológicos.Resultados. De 163 pacientes, se incluyó a 23 (media de edad: 6,1 años) en el GA y a 140 (media de edad: 8,1 años) en el GSA. Los pacientes en el GA tuvieron una hospitalización más extensa, mayor temperatura corporal, mayor frecuencia de diarrea, signo de Blumberg, aumento del porcentaje de neutrófilos, proteína C-reactiva y mayor riesgo de perforación. La puntuación en las escalas de Alvarado (8,3 ± 1,2 frente a 7,0 ± 1,3; P < 0,05) y de respuesta inflamatoria a apendicitis (10,7 ± 1,6 frente a 7,7 ± 1,9; P < 0,05) fue mayor en el GA que en el GSA; la presencia de fiebre y apendicolito se asoció con una mayor tasa de apendicitis perforada.Conclusiones. La apendicitis pediátrica con apendicolito representa un mayor riesgo clínico y tiende a causar apendicitis complicada

Objectives. This study aims to assess the clinical risk of pediatric appendicitis with appendicolith and its guiding significance in therapeutic strategies' selection.Methods. Children diagnosed with acute appendicitis from June 2011-January 2017 were analyzed retrospectively. Patient cohort was divided to appendicolith group (AG) and non- appendicolith group (NAG) based on whether the appendicolith presents or not in the open surgery. Clinical presentations, laboratory parameters, computed tomography findings, and pathological changes were reviewed and compared between two groups. Results. Among 163 patients, 23 (meanage,6.1yearsold)weredefinedin AG and 140; mean age, 8.1 years old) in NAG. The patients in AG demonstrated prolonged length of stay (12.4 ± 5.6d vs. 8.7 ± 5.0d, P <0.05), higher body temperature (38.2 ± 0.8 °C vs. 37.3 ± 0.8 °C, P <0.05), higher frequency of diarrhea (17 % vs. 3%, P <0.05), rebound tenderness (100 % vs. 87 %, P <0.05), increased neutrophil percentage (81.4 ± 8.0 % vs. 65.3 ± 22.8 %, P <0.05), C-reactive protein (33.13 ± 10.3 mg/L vs. 23.7 ± 13.7 mg/L, P <0.05), and great risk of perforation (78 % vs. 29 %, P <0.05). Alvarado score (8.3 ± 1.2 vs. 7.0 ± 1.3, P <0.05) and AIR score (10.7 ± 1.6 vs. 7.7 ± 1.9, P <0.05) of AG, were higher than NAG he presence of fever and appendicolith was associated with a high rate of perforated appendicitis.Conclusions.

Quiste pulmonar congénito gigante que imita neumotórax a tensión en un niño / Huge congenital cystic lung lesion mimicking tension pneumothorax in a child

El tratamiento de los lactantes con quistes pulmonares congénitos conlleva una resección quirúrgica. Las variaciones en la ubicación y el tamaño del quiste de aire en el pulmón afectado implican la selección de diferentes estrategias quirúrgicas. La presencia de quistes pulmonares congénitos gigantes que imitan un neumotórax a tensión no permitiría tomar una decisión precisa y realizar un tratamiento oportuno durante una emergencia respiratoria. Los escasos informes sobre este tipo de experiencia hacen referencia a quistes a tensión durante la niñez. En este artículo, presentamos el caso de un niño con un quiste pulmonar congénito gigante que imita neumotórax a tensión según las manifestaciones clínicas y las evaluaciones del diagnóstico por imágenes. La descompresión instantánea del neumotórax a tensión no logró aliviar la dificultad respiratoria del niño. En los niños que presentan evidencia clínica de neumotórax a tensión, se debe excluir la posibilidad de un quiste pulmonar congénito gigante.

Treats of symptomatic infants with congenital cystic lung lesions (CCLLs) need surgical resection. Variable location and size of the air cyst of involved lung mean that different surgical strategies must be selected. The presence of huge CCLLs mimicking tension pneumothorax would hamper accurate judgment and timely treatment in dealing with respiratory emergencies. Rare experience reports are coping with childhood tension cystic lung lesion. We present a case of childhood huge CCLLs which was similar to tension pneumothorax based on clinical manifestations and imaging evaluations. Implementation of instant decompression measure against tension pneumothorax failed to alleviate respiratory distress of child. We should exclude the possibility of huge lung cystic lesion in children when clinical evidence inclines to the diagnosis of tension pneumothorax.
