Fournier's gangrene by perianal abscess

Gangrena de Fournier por abscesso perianal



To describe and analyze the cases of Fournier's Gangrene caused by perianal abscess treated in a tertiary hospital in western Paraná, correlating possible factors that influence mortality, with emphasis on late diagnosis and therapy.


A retrospective and descriptive case series was carried out based on the analysis of medical records of patients with Fournier's Gangrene due to perianal abscess from January 2012 to December 2017.


Thirty-one patients with Fournier's Gangrene due to perianal abscess were treated in the period: 26 men and 5 women. Mean age was 53.51 ± 14.5 years. The most prevalent comorbidity in this group was type 2 diabetes mellitus, showing a strong correlation with mortality. The mean time from disease progression, from the initial symptom to the admission at the service, was 9.6 ± 6.81 days. All patients were submitted to antibiotic therapy and surgical treatment, with a mean of 3.25 ± 2.89 procedures/patient. Seven (22.58%) patients died and all of them showed signs of sepsis on admission; only 2 patients with sepsis did not die.


The presence of sepsis on admission and type 2 diabetes mellitus were strongly correlated with mortality.
