Intra-abdominal abscesses are pus-filled pouches in the abdominal cavity. Current standard of
care includes drain placement in the abscess cavity to reach source control as well as
administration of systemic antibiotics. It is common practice to flush the drain on a daily
basis to ensure patency. This study aims to analyze the clinical impact of a higher local
concentration of antibiotics (rather than normal saline) provided through drain irrigation
with an antimicrobial agent (Gentamicin and/or Clindamycin) compare to normal saline.
