Outcome of Fournier’s gangrene in relation to Fournier Gangrene Severity Index (FGSI) score

Abstract

ABSTRACT Introduction: Fournier’s gangrene is a rapidly progressive necrotizing fasciitis, involving perineum mainly. The purpose of the study is to evaluate etiology, treatment, and outcome of Fournier’s gangrene so that such type patient’s management can be done by primary care physicians with best outcomes. Method: This was a retrospective study including 156 patients, treated for Fournier’s gangrene, between Jan 2012 and Dec 2018. The outcome and prognosis of Fournier’s gangrene were reviewed. Result: The mean age and mode among survival patients were 47.94 ± 14.9 and 60 years, and the mean age and mode in nonsurvival patients was 47.64 ± 15.9 and 65 years. The most common predisposing factor was diabetes mellitus (n = 49, 31.4%) having mortality rate was 9% (n = 14). Most common causative bacteria were E. coli. In the study, the survival rate was 100% in patients having Fournier Gangrene Severity Index (FGSI)≤3. As FGSI increased from 3, the mortality rate increased. Conclusion: Fournier gangrene is a surgical emergency. Early diagnosis, serial surgical debridement, and broad-spectrum antibiotics decrease the mortality and morbidity of patients. The sensitivity and specificity of FGSI determine the prognosis of Fournier’s gangrene. FGSI is a simple method to know the severity and prognosis.
