Prevalencia bacteriológica en apendicitis aguda no complicada y su asociación con infección del sitio quirúrgico, Hospital Vicente Corral Moscoso, 2010

Abstract

The acute apendicitis (AA) afects to 12% of the poblation, the morbility of this pathology and its treatment produce suffering, more hospitary stay, delay work and socioeconomic repercussions. The germs culture of the appendix wall is multifactorial depends of: guest, surgeon, hospitary ambient, and clinic phase; the fecuently of the wound infection (WI) vary of 2 to 10% and should relate with appendix germs. Objective: To determine the germs prevalency of the appendix wall in patients with non-complicated acute appendicitis and association with pathology time and WI in patients of Vicente Corral Hospital (octuber 2009 - september 2010). Methodology: We achieved a transversal study to determine the bacteriological prevalency of the wall appendix in patientes with non-complicated acute apendicitis and its relation with wound infection. Outcomes: We study 114 patients, 107 (93.9%) patients show positive culture of the appendix wall; 87,7% show a process upper to 12h. 60,5% of appendix were supuratives. The appendix wall culture show a hight incidence of E. Coli (64,5%), and Bacteroides frágilis (19,6%). The frecuently of ISQ was 10,5%. Therefore, presence of anaerobic germs and the ISQ were associated with a upper to 12 h evolution of this pathology, but the diference was not significantly. Conclusion: The wall appendix culture is not frecuently, the presence of germs in the wall appendix increase according to time of evolution of this pathology and its associated with increase of ISQ but without stadistical significantly. The germs find in non-complicated acute apendicitis were E. Coli y B, Frágilis.
