Introduction: Acute appendicitis is the leading cause of abdominal surgical emergencies in pediatrics. Between 30% and 75% of cases progress to perforated appendicitis; however, timely diagnosis before perforation occurs remains a challenge. Objective: To identify predictive factors for perforated appendicitis in a pediatric population (<18 years) at the time of admission to the emergency department. Materials and methods: Prospective cohort study conducted in 193 patients (perforated appendicitis=98; nonperforated appendicitis=95) admitted to the emergency department of a pediatric referral hospital in Bogotá D.C., or referred to such hospital, who underwent appendectomy between November 1 and December 31, 2013. Bivariate analyses were performed (Student's t-tests, Mann-Whitney U, chi-square or Fisher's exact), calculating the odds ratios (OR) with their respective 95%CI. In the multivariate analysis (logistic regression), the stepwise regression method was used to select variables according to their statistical significance, and regression models were performed. The explanatory power of the models was verified by calculating the areas under the ROC curve. Results: The mean age of the participants was 9.8 years, and the prevalence of perforated appendicitis was 50.78%. The following predictive factors for perforated appendicitis were identified in the multivariate analysis: presence of emesis on admission to the emergency department (OR=4.28, 95%CI: 1.63-11.21), presence of tachycardia on physical examination (OR=3.38, 95%CI:1.69-6.59), temperature >38.3°C on physical examination (OR=3.36, 95%CI: 1.29-8.70), and duration of symptoms until surgery (OR=1.95, 95%CI: 1.37-2.77). Conclusions: In the present study, duration of symptoms until surgery, presence of emesis during questioning on admission to the emergency department, and presence of tachycardia and fever (>38.3°) on physical examination behaved as predictive factors for acute perforated appendicitis in pediatric patients.

Introducción. La apendicitis aguda es la principal causa de urgencia quirúrgica abdominal en población pediátrica. Entre 30% y 75% de los casos progresan a apendicitis perforada; sin embargo, el diagnóstico oportuno de esta condición antes de que ocurra la perforación continúa siendo un reto. Objetivo. Identificar los factores predictores de apendicitis perforada en población pediátrica (<18 años) al momento de ingreso al servicio de urgencias. Materiales y métodos. Estudio de cohortes prospectivo realizado en 193 pacientes (apendicitis perforada=98; no perforada=95) admitidos al servicio de urgencias de un hospital pediátrico de referencia en Bogotá D.C., Colombia, o remitidos a dicho hospital y a los que se les realizó apendicectomía entre noviembre 1 y diciembre 31 de 2013. Se realizaron análisis bivariados (pruebas t-Student, U de Mann-Whitney, chi cuadrado o exacta de Fisher), calculando Odds ratio (OR) con sus respectivos IC95%. En el análisis multivariado (regresión logística) se utilizó el método de regresión paso a paso para seleccionar las variables según su significancia estadística y se realizaron modelos de regresión. La capacidad de explicación de los modelos se verificó con el cálculo de áreas bajo la curva ROC. Resultados. La edad promedio de los participantes fue 9.8 años y la prevalencia de apendicitis perforada fue 50.78%. En el análisis multivariado se identificaron los siguientes factores predictores para apendicitis perforada: presencia de vómito en el interrogatorio al ingreso a urgencias (OR=4.28, IC95%: 1.63-11.21), presencia de taquicardia en el examen físico (OR=3.38, IC95: 1.69-6.59), temperatura >38.3°C en el examen físico (OR=3.36, IC95%: 1.29-8.70) y la duración de los síntomas hasta la cirugía (OR=1.95, IC95%: 1.37-2.77). Conclusiones. En este estudio, la duración de los síntomas hasta la cirugía, la presencia de vómito en el interrogatorio al ingreso a urgencias y la presencia de taquicardia y de fiebre (>38.3°C) al examen físico se comportaron como factores predictores de apendicitis aguda perforada en pacientes pediátricos.
