ABSTRACT

Objective To investigate the clinical features and therapy of fournier's gangrene.Methods The clinical data of 12 patients with fournier's gangrene who were treated at the Third Affiliated Hospital of Nanjing University of Chinese Medicine from January 2010 to February 2012 were retrospectively analyzed.Eleven patients had perianal abscess and 1 patient had perianal foreign body,most of the patients were presented with perianal pain,fever (＞ 38.5 ℃) and tachycardia.The mean interval between the onset of symptoms and admission to the hospital was 8 days (range,3-20 dyas).Seven patients were complicated with diabetes.Only 2 patients were administered hypoglycemic agents,but the effects were poor.Six patients were complicated with hypertension.One patient had the history of resection of sigmoid colon cancer 2 months before operation.Debridement and drainage were applied to all the patients after examination.Antimicrobial therapy applied to all the patients according to the results of drug sensitivity test.The incisions were washed by hydrogen peroxide solution postoperatively.Redebridement was applied if the disease was progressed.All patients were followed up via out-patient examination and phone call till June 2012.Results Results of clinical featuresPerianal tissues necrotized,with the color of black.The scrotum or labia majora of 8 patients were invaded by the necrotic tissues.Results of laboratory testthe white blood cell count was (3.8-27.6) × 109/L,the white blood cell count of 6 patients was above 10 × 109/L,3 was above 20 × 109/L.The ratio of neutrophil granulocytes was 0.61-0.93.Four patients received single debridement,5 received redebridement,and 3 patients received debridement for more than 2 times.Two patients had sapremia and infectious shock,and they received treatment for 3 days and 4 days at the intensive care unit.Results of bacterial culture6 patients were infected by the escherichia coli,4 by klebsiella pnenmoniae,and 1 by pseudomonas aeruginosa.The mean duration of hospital stay was (25± 14)days (range,1-49 days).All patients were followed up for 4-29 months,1 patient was discharged at postoperative day 2,and the prognosis of the 11 patients was good,no mortality was observed.Conclusions The clinical features of fournier's gangrene include severe pain and rapid spread of infections caused by necrosis of perianal subcutaneous tissues.Diabetes might be the risk factor of fournier's gangrene.Early diagnosis and prompt and aggressive surgical debridement are critical for improving survival.
