OBJECTIVES: To identify the prognostic factors and the new parameters that might predict a worse outcome in nonsurvivors compared with survivors of Fournier's gangrene (FG) and evaluated the validity of the Fournier's Gangrene Severity Index (FGSI) in patients with FG. METHODS: The medical records of 18 patients with FG who were treated and followed up in our clinic were reviewed. Data were collected in terms of medical history, symptoms, and physical examination findings. The biochemical, hematologic, and bacteriologic study (aerobic and anaeorobic wound cultures) results at admission and at the final evaluation, the physical examination findings, the timing and extent of surgical debridement, and the antibiotic therapy were also recorded. The Charlson Comorbidity Index (CCI) and FGSI were evaluated stratified by survival. RESULTS: The results were evaluated for 2 groups: those who survived (n = 14) and those who did not (n = 4). The admission FGSI score was 5.00 +/- 2.91 (range 0-10) for survivors compared with 13.5 +/- 2.62 (range 9-15) for nonsurvivors (P = .001). The CCI score was 3 +/- 1.5 in survivors and 7 +/- 2.2 in nonsurvivors (P = .008). Individual laboratory parameters such as hypomagnesemia, hemoglobin, hematocrit, alkaline phosphatase, creatinine, and the heart and respiratory rates were associated with a worse prognosis. In addition, a FGSI >9, rectal involvement, colostomy diversion, and a high CCI were associated with high mortality. CONCLUSIONS: Low magnesium levels might be a new parameter for a worse prognosis. High CCI and FGSI scores might be associated with a worse prognosis in patients with FG. A FGSI threshold of 9 was a predictor of mortality during the initial assessment. Copyright 2010 Elsevier Inc.
