Introduction: Appendicitis can be classified as non-perforated and perforated; based on such classification, the reported organ-space surgical site infection (OS-SSI) rate is 0.8% and 18%, respectively.
Objective: To establish the prevalence of OS-SSI in patients with perforated appendicitis treated in a pediatric hospital in 2012.
Materials and methods: Retrospective, observational and descriptive study conducted at Fundación Hospital Pediátrico La Misericordia, with a random sample of 200 patients, of which 160 met the inclusion criteria.
Results: 20 patients (12.5%) presented with OS-SSI and all of them received antibiotic treatment; 70% did not require abscess drainage. Patients ≥8 years of age had 5 times more abscesses than younger ones (17.6% vs. 3.4%). OS-SSI was found in 33% of patients with free fecalith and in 50% of the patients who required postoperative management at the ICU vs. 9.5% of the patients who received management in the intermediate care unit and the inpatient hospital floors. The total rate of surgical site infection was 24.3% (11.8% superficial, 0% deep and 12.5% organ-space).
Conclusions: The prevalence of OS-SSI found here is lower than what has been reported in the literature. Being 8 years or older and having free fecalith are risk factors to develop this type of infection. The higher frequency of OS-SSI in patients treated at the ICU during the post-operative period observed here suggests that this condition may be associated with septic shock.
Introducción. La apendicitis se clasifica en no perforada y perforada; de acuerdo a esta clasificación, la tasa de infección del sitio operatorio órgano-espacio (ISO-OE) es de 0.8% y 18%, respectivamente.
Objetivo. Determinar la prevalencia de ISO-OE en pacientes con apendicitis perforada en un hospital pediátrico en 2012.
Materiales y métodos. Estudio retrospectivo y observacional descriptivo de corte transversal. La muestra fue aleatoria y de 200 pacientes, 160 cumplieron los criterios de inclusión.
Resultados. Los 20 pacientes (12.5%) que presentaron ISO-OE recibieron manejo antibiótico; 70% no requirió drenaje de colección. Los pacientes ≥8 años presentaron 5 veces más ISO-OE (17.6% vs. 3.4%). El 33% de los pacientes con fecalito en cavidad y el 50% que se hospitalizó en post-operatorio inmediato en la unidad de cuidados intensivos (UCI) desarrollaron ISO-OE versus 9.5% de los pacientes atendidos en la unidad de cuidados intermedios y pisos. El total de ISO fue 24.3%: 11.8% superficial, 0% profunda y 12.5% de órgano-espacio.
Conclusiones. La prevalencia de ISO-OE encontrada es menor a la reportada en la literatura. La edad ≥8 años y el fecalito en cavidad son factores de riesgo para desarrollar este tipo de infección. La mayor frecuencia de ISO-OE en pacientes manejados en el posoperatorio en UCI sugiere que esta condición puede estar asociada con el choque séptico.
