Fournier's Gangrene: A Review and Outcome Comparison from 2009 to 2016.

The outcome of Fournier's gangrene (FG) may be affected by comorbidities, demographics, and choice of treatment modality. We sought to evaluate our institution's management protocol of FG measured by mortality rate (MR) and length of hospital stay (LHS) in a retrospective cohort study. A database of 20 FG cases at our institution throughout the 2009-2016 study period was assembled by a retrospective review of medical records. A Fournier's Gangrene Severity Index Score (FGSIS) was calculated for each case. Data were analyzed for statistical significance using logistic regression. The most common presentation of FG at our institution was a hyperglycemic diabetic male in his fifth decade of life with a second risk factor such as recent surgery or active malignancy. The average FGSIS was 9 overall and 14 for the mortalities. An increased FGSIS was predictive of having an increased MR or hospital stay above the median (>25 days) ( = 0.0194). The average LHS was 32 days overall, 22 days for patients treated with hyperbaric oxygen therapy and 40 days for patients treated with tangential hydrosurgery. Overall MR was 15%. This is the second known study to characterize usage of tangential hydrosurgery in the management of FG. Treatment outcomes at our institution are comparable to those reported in recent literature, a significant decline from the historical MR of 50-60%.
