| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| Determine the clinical response of the addition of local antibiotic therapy to the standard treatment of intra-abdominal abscesses |  
| Determinar la respuesta clínica de la adición de antibioterapia local al tratamiento estándar de los abscesos intraabdominales. |  | 
| E.2.2 | Secondary objectives of the trial | 
| - Determine the time until microbiological eradication / negativization of cultures in the groups under study
 - Study the development of clinical complications: severe sepsis,
 kidney failure, others.
 - To establish if local antibiotic therapy addition reduces the risk of
 subsequent invasive or surgical procedures; such as:
 percutaneous drains, endoscopic drainage or open laparotomy.
 - Assess systemic antimicrobial use by episode
 |  
| − Determinar el tiempo hasta la erradicación microbiológica /negativización de los cultivos en los grupos a estudio
 − Estudiar el desarrollo de complicaciones clínicas: sepsis grave,
 insuficiencia renal, otras.
 − Establecer si la adición de antibioterapia local reduce el riesgo de
 procedimientos invasivos o quirúrgicos subsecuentes; tales como:
 drenajes percutáneos, drenajes vía endoscópica o laparotomía abierta.
 − Valorar el consumo de antimicrobianos por vía sistémica por episodio
