Risk factors for infection in the residual cavity after liver hydatidosis surgery in patients from the Peruvian highlands

Abstract

Objective: To determine the risk factors with the infection in the residual cavity after hepatic cystectomy in the patients of the Ramiro Prialé Prialé hospital - EsSalud -Huancayo. Materials and Methods: A retrospective cohort was conducted, between January 2014 and January 2018. A data collection sheet was used. Crude and adjusted relative risks (RR) were obtained, with 95% confidence intervals. Results: 83 patients participated. 41.2% of women infected in the post-cystectomy cavity and the median age of infected patients was 33 years. The pathological antecedents that were related to the infection were obesity or overweight (62.5%), previous neoplasia (100%) and previous immune disease (31%). Post-cystectomy residual cavity infection was affected by the presence of obesity or overweight (aRR: 1.56; 95% CI: 1.15-2.13; p value = 0.005), diabetes mellitus (aRR: 2.67; 95% CI : 2.09-3.41; p value <0.001), previous neoplasia (aRR: 2.49; 95% CI: 1.94-3.20; p value <0.001), previous surgery (aRR: 1.49; 95% CI: 1.36-1.64; p value <0.001) and the use of post-surgery antibiotics (aRR: 2.14; 95% CI: 1.30-3.51; p value = 0.003) Conclusions: Obesity or overweight, diabetes mellitus, having suffered some neoplasia or previous surgery and the use of antibiotics after surgery; they are factors associated with infection in the residual post-cystectomy liver cavity in patients of the Ramiro Prialé Prialé EsSalud National Hospital in Huancayo, Peru
