Abstract
Evaluar la asociación entre el volumen de lavado peritoneal (LP) y absceso residual (AR) en pacientes operados por apendicitis aguda complicada (AAC).
Métodos: Se realizó un estudio observacional analítico transversal en pacientes operados por AAC en el Hospital Regional Docente de Trujillo (HRDT) entre 2016-2019 y 2022. Se analizaron 125 historias clínicas seleccionadas por muestreo censal. Mediante modelos lineales generalizados de la familia de Poisson se calcularon las razones de prevalencias ajustadas (RPa) por edad y sexo.
Resultados: El 63,20% de los pacientes fueron hombres, y el grupo etario predominante tenía entre 18 y 30 años (42,40%). La mediana del volumen de LP fue de 2 litros (RIC 1-4), siendo el rango ≤ 1 litro el más frecuente (37,60%). La frecuencia de AR fue del 20,80%. No se encontraron diferencias estadísticamente significativas en la presencia de AR entre los rangos de volumen de LP (p = 0,540). En los modelos ajustados, el LP de ≥ 5 litros no mostró asociación significativa con AR (RPa: 0,57; IC 95%: 0,23-1,43, p = 0,232).
Conclusión: El volumen de LP no se asoció significativamente con la presencia de AR en pacientes con AAC. Se requieren estudios adicionales para establecer recomendaciones clínicas definitivas.

Abstract To evaluate the association between peritoneal lavage (PL) volume and residual abscess (RA) in patients undergoing surgery for complicated acute appendicitis (CAA). Methods: A cross-sectional analytical observational study was conducted on patients operated on for CAA at the Regional Teaching Hospital of Trujillo (HRDT) between 2016–2019 and 2022. A total of 130 medical records were analyzed, selected through census sampling. Adjusted prevalence ratios (aPR) for age and sex were calculated using generalized linear models of the Poisson family. Results: Of the patients, 63.20% were male, and the predominant age group was 18–30 years (42.40%). The median PL volume was 2 liters (IQR 1–4), with the ≤1-liter range being the most frequent (37.60%). The frequency of RA was 20.80%. No statistically significant differences were found in the presence of RA across PL volume ranges (p = 0.540). In adjusted models, PL volumes ≥5 liters showed no significant association with RA (aPR: 0.57; 95% CI: 0.23–1.43, p = 0.232). Conclusion: PL volume was not significantly associated with the presence of RA in patients with CAA. Further studies are needed to establish definitive clinical recommendations.
