          Abstract

          RESUMEN Fundamento: la gangrena de Fournier es una infección polimicrobiana grave ocasionada por microorganismos que actúan de modo sinérgico y determinan una fascitis necrosante progresiva en escroto y periné con manifestaciones de sepsis que pueden evolucionar a choque séptico y fallo de órganos. Objetivo: caracterizar clínica e epidemiológicamente la gangrena de Fournier en pacientes diagnosticados en una unidad hospitalaria de referencia. Métodos: estudio retrospectivo, observacional y descriptivo a partir del análisis de los expedientes clínicos de 64 pacientes masculinos con gangrena de Fournier, diagnosticados en el Hospital Militar Principal/Instituto Superior de Luanda, República de Angola de enero de 2016 a diciembre de 2020. Las variables de estudio fueron: edad, hábitos tóxicos, comorbilidad, manifestaciones clínicas, extensión, localización así como su evolución. Las variables cuantitativas fueron expresadas en medias, mediana y rango, mientras que las variables cualitativas se expresaron en términos de números absolutos y porcentajes. Resultados la edad promedio fue 45,09 años; 36 pacientes (56,2 %) consumen bebidas alcohólicas y 14 (21,87 %) declararon hábitos tabáquicos. La principal comorbilidad fue la diabetes mellitus en 21(32,8 %). El dolor con aumento de volumen del escroto predominó en 43(67,2 %) sujetos; el desbridamiento quirúrgico precoz con antibióticoterapia fue la clave de manejo. Fallecieron cinco pacientes. Conclusiones: la gangrena de Fourner es una enfermedad grave que puede presentar repercusión sistémica y muerte. La piedra angular en el tratamiento es el desbridamiento quirúrgico precoz apoyado en medidas de soporte. La serie presentada mostró un manejo multidisciplinario adecuado y eficaz.

          ABSTRACT Background: Fournier's gangrene is a serious polymicrobial infection caused by microorganisms that act synergistically and determine a progressive necrotizing fasciitis in the scrotum and perineum with manifestations of sepsis that can progress to septic shock and organ failure. Objective: to characterize clinically and epidemiologically Fournier's gangrene in patients diagnosed in a reference hospital unit. Methods: retrospective, observational and descriptive study based on the analysis of the clinical records of 64 male patients with Fournier's gangrene, diagnosed at the Hospital Militar Principal/Instituto Superior de Luanda, Republic of Angola from January 2016 to December 2020. Study variables were: age, toxic habits, comorbidity, clinical manifestations, extension, location as well as its evolution. The quantitative variables were expressed as means, median and range, while the qualitative variables were expressed in terms of absolute numbers and percentages. Results: the average age was 45.09 years; 36 patients (56.2%) consume alcoholic drink and 14 (21.87%) declared smoking habits. The main comorbidity was diabetes mellitus in 21 (32.8%). Pain with increased scrotal volume predominated in 43 (67.2%) subjects; early surgical debridement with antibiotic therapy was the key to management. Five patients died. Conclusions: Fourner's gangrene is a serious disease that can present systemic repercussions and death. The cornerstone of treatment is early surgical debridement supported by support measures. The series presented showed adequate and effective multidisciplinary management.

          Fournier's gangrene. A clinical review.

          Fournier's gangrene is a rare, necrotising fasciitis of the external genitalia, perineal or perianal regions. The disease has a higher incidence in males and risk factors for development include diabetes, HIV, alcoholism and other immune-compromised states. The aggressive disease process is associated with a high mortality rate of 20-30%. In addition, the increasing age and prevalence of diabetes in the population, begs the need for increased clinical awareness of Fournier's gangrene with emphasis on early diagnosis and management. This review aims to highlight the relevant research surrounding Fournier's gangrene, in particular the various prognostic indicators and management strategies.

            A retrospective case series of Fournier’s gangrene: necrotizing fasciitis in perineum and perianal region

            Background To describe the clinical characteristics and management for Fournier’s gangrene. Experience summary and literature references are provided for future treatment improvement. Methods We retrospectively reviewed the cases diagnosed with Fournier’s gangrene in our department from June 2016 to June 2019. Clinical data, including manifestation, diagnosis, treatment and outcomes for Fournier’s gangrene were presented. Results There were 12 patients enrolled in this paper, with the average age of 60 years old. It showed a male predominance with male-to-female ratio of 6:1. The average of laboratory risk indicator for necrotizing fasciitis (LRINEC) score was 10.1. Diabetes mellitus was the main predisposing disease. 11 patients received emergency debridement and 1 patient died of sepsis on the 2nd day after admission. The mortality rate was 8.3%. 6 cases developed complications, including sepsis, pneumonia, renal and heart failure. Negative pressure wound therapy (NPWT) was applied in 10 cases, while the rest 1 received normal daily dressing changes because of fecal contamination. Flaps were utilized in 2 patients to cover the defect, including one with advancement flap and one with pudendal-thigh flap, while others received secondary suture, secondary healing, skin graft or combined management. No relapse was observed during the follow-up visits. Conclusions Fournier’s gangrene is a life-threatening infection that requires early diagnosis and surgery intervention. The predisposing disease, clinical manifestation and LRINEC score should be taken into comprehensive consideration, which is helpful for timely diagnosis. Moreover, further successful treatment depends on the aggressive debridement, broad-spectrum antibiotics therapy, wound management and closure choice.

              Fournier’s Gangrene: Lessons Learned from Multimodal and Multidisciplinary Management of Perineal Necrotizing Fasciitis

              Background Fournier’s gangrene (FG) is a rapidly evolving necrotizing fasciitis of the perineum and the genital area, the scrotum as it most commonly affects man in the vast majority of cases. It is polymicrobial in origin, due to the synergistic action of anaerobes and aerobes and has a very high mortality. There are many predisposing factors including diabetes mellitus, alcoholism, immunosuppression, renal, and hepatic disease. The prognosis of the disease depends on a lot of factors including but not limited to patient age, disease extent, and comorbidities. The purpose of the study is to describe the experience of a general surgery department in the management of FG, to present the multimodal and multidisciplinary treatment of the disease, to identify predictors of mortality, and to make general surgeons familiar with the disease. Methods The current retrospective study is presenting the experience of our general surgery department in the management of FG during the last 20 years. The clinical presentation and demographics of the patients were recorded. Also we recorded the laboratory data, the comorbidities, the etiology, and microbiology and the therapeutic interventions performed, and we calculated the various severity indexes. Patients were divided to survivors and non-survivors, and all the collected data were statistically analyzed to assess mortality factors using univariate and then multivariate analysis. Results In our series, we treated a total of 24 patients with a mean age 58.9 years including 20 males (83.4%) and 4 females (16.6%). In most patients, a delay between disease onset and seeking of medical help was noted. Comorbidities were present in almost all patients (87.5%). All patients were submitted to extensive surgical debridements and received broad-spectrum antibiotics until microbiological culture results were received. Regarding all the collected data, there was no statistically significant difference between survivors and non-survivors except the presence of malignancy in non-survivors (p = 0.036) and the lower hemoglobin (p < 0.001) and hematocrit (p = 0.002) in non-survivors. However, multivariate analysis did not reveal any predictor of mortality. Conclusion Early diagnosis, aggressive thorough surgical treatment, and administration of the proper antibiotic treatment comprise the cornerstone for the outcome of this disease. In small populations like in the present study, it is difficult to recognize any predictors of mortality and even the severity indexes, which take into account a lot of data cannot predict mortality.
