November 13, 2009 updated by: Ankara University

Does Adjuvant Antibiotic Treatment After Drainage of Anorectal Abscess Prevent the Development of Anal Fistulae? A Prospective Randomized, Placebo Controlled, Double Blind, Multi-Center Clinical Study

Purpose: This randomized study assesses the effects of antibiotics on the formation of fistulae after drainage of anorectal abscesses.

Methods: Patients who underwent abscess drainage in 3 major colorectal units between September 2005 and January 2008 were included. Previous anorectal surgery history, immunecompromised states, pregnancy, inflammatory bowel disease, antibiotic usage prior to surgery and the presence of an anal fistulae at the time of surgery were the exclusion criteria.
