The aim of this study was to determine the guideline of usage of antibiotics for<br>anonectal suppurative disease. This study was conducted in consecutive 96 patients, who<br>were taken surgical treatments for the anorectal abscess at the department of general<br>surgery of Ewha Womans University Hospital, from January 1990 to December 1994. All<br>subjects were classified in terms of age, gender, duration, history, associated disease,<br>classification, location, and isolation of organism. The incidence of the anorectal abscess<br>was highest in the 3rd and 4th decade of age and male in terms of gender. 80.3% of all<br>patients were admitted within 10 days after onset. The most common past history of<br>anorectal disease was the anorectal abscess(15 cases, 15.6%) and the associated systemic<br>disease was tuberculosis(9 cases, 9.4%). The main type of anoreclal abscess was the<br>perianal abscess(87.5%) and the most frequent location was posterior area(39.6%). In the<br>pus culture and isolation test, 90.6% of all patients had colony formation and the most<br>frequently cultured organism was E.coli(55 cases,57.3%), followed by Klebsiella<br>species(15 cases,15.6%) and anaerobic Bacteroid species(14 cases,14.6%). In antibiotic<br>sensitivity test, the 3rd generation of aminoglycoside was sensitive in 89 cases and<br>resistant in 3 cases, and the 3rd generation of cephalosporin was sensitive in 87 cases<br>and resistant in 5 cases. These results suggest that the 3rd generation of<br>aminoglycoside or the 3rd generation of cephalosporin could be selected to treat the<br>anorectal suppurative disease.<br>
