Gangrena de Fournier: Estudio retrospectivo de 41 casos

Early Diagnosis and Treatment Outcomes of Fournier Gangrene in a Tertiary Center

INTRODUCTION

Fournier gangrene is an uncommon urological emergency caused by microbial agents, resulting in necrosis of the genitalia and perineum. This study aims to evaluate the outcomes of early diagnosis and management of Fournier gangrene at KAMC in Riyadh, Saudi Arabia.

METHODS

A retrospective cohort study was conducted at KAMC, Saudi Arabia. The study population included all adult patients diagnosed with Fournier gangrene between 2015 and 2022. Data analysis was performed using RStudio (RStudio, Boston, MA). Frequencies and percentages were used to present categorical data, while medians and interquartile ranges were used to express numerical variables.

RESULTS

The study included 41 patients with Fournier gangrene, the majority (95.12%) being male with a median age of 60 years. The most prevalent comorbidity was diabetes mellitus (85.37%). Ten patients presented to the hospital with sepsis, two of whom were in shock. Within 90 days of admission, two of them had expired. This resulted in a 20% mortality rate among septic patients. The mean FGSI in patients who had died during hospital stays was approximately two times the mean in surviving patients (8.17 and 4.32, respectively). The most utilized imaging study was a CT scan (70.7%). Most patients had undergone multiple debridements (87.7%). The median number of debridements per patient was three, and the interval between each debridement was three days. The most frequent tissue culture finding was mixed organisms, followed by Escherichia coli. Regarding empiric antibiotics, tazocin was the most used, accounting for 22.0%. The most frequently performed adjunctive procedure was the placement of a suprapubic catheter, accounting for 41.5%. Roughly 43.90% required a blood transfusion. Within 90 days of admission, six patients had died, which makes the mortality rate 14.6%. Four of them had died within 30 days of admission (9.76%).

CONCLUSION

Fournier gangrene is a surgical emergency that requires prompt attention and resuscitation, antibiotic therapy, and surgical debridement. The study identified the demographic factors of patients who presented with the disease and provided the incidence, mortality rate, and outcomes of the disease. It also identified specifics of the pharmacological and surgical management and hospital courses.

Variables that predict hospital stay and the outcome of Fournier gangrene at King Abdulaziz University Hospital: a retrospective study

BACKGROUND

The aggressive nature of Fournier gangrene and the associated health issues can result in a more complex clinical course and potentially a longer hospital stay. This study aimed to assess factors that affect the length of hospital stay (LHS) and its relation to the outcome of Fournier gangrene patients.

METHODS

A retrospective study was performed at King Abdulaziz University Hospital (KAUH), Saudi Arabia, on patients diagnosed with Fournier gangrene between 2017 and 2023. Data about length of hospital stay (LHS), age, BMI, clinical and surgical data and outcome was obtained.

RESULTS

The mean age of the studied patients was 59.23 ± 11.19 years, the mean body mass index (BMI) was 26.69 ± 7.99 kg/m2, and the mean duration of symptoms was 10.27 ± 9.16 days. The most common presenting symptoms were swelling or induration (64%), 88% had comorbidities with diabetes mellitus (DM) (84%), and 76% had uncontrolled DM. of patients, 24% had a poly-microbial infection, with E. coli being the most common (52%). The mean length of hospital stay (LHS) was 54.56 ± 54.57 days, and 24% of patients had an LHS of more than 50 days. Longer LHS (> 50 days) was associated with patients who did not receive a compatible initial antibiotic, whereas shorter LHS was associated with patients who received Impenem or a combination of vancomycin and meropenem as alternative antibiotics following incompatibility. Reconstruction patients had significantly longer LHS and a higher mean temperature. However, none of the studied variables were found to be predictors of long LHS in the multivariate regression analysis.

CONCLUSION

Knowledge of the values that predict LHS allows for patient-centered treatment and may be useful in predicting more radical treatments or the need for additional treatment in high-risk patients. Future multicenter prospective studies with larger sample sizes are needed to assess the needed variables and predictors of long LHS.

Effect of Sarcopenia on Mortality and Morbidity in Patients With Fournier's Gangrene

BACKGROUND

Preoperative sarcopenia is an essential factor that negatively affects postoperative results. The effect of preoperative sarcopenia on postoperative complications and prognosis in patients treated for Fournier's gangrene (FG) is controversial. This retrospective cohort study analyzed the effect of FG to evaluate the effect of preoperative sarcopenia on postoperative complications and prognosis in patients who were operated on.

METHOD

The data of patients who were operated on with FG diagnosis in our clinic between 2008 and 2020 were reviewed retrospectively. Demographic data (age and gender), anthropometric measurements, preoperative laboratory values, abdominopelvic CT, location of FG, number of debridements, ostomy, microbiological culture result, wound closure method, length of hospital stay, and overall survival were recorded. In addition, the presence of sarcopenia was determined according to psoas muscular index (PMI) and Hounsfield unit average calculation (HUAC).

RESULTS

Of the patients, 57 (30.8%) were female and 128 (69.2%) were male. According to the PMI, sarcopenia was detected in 67 (36.2%) patients and 70 (37.8%), according to the HUAC. At the end of one postoperative year, the mortality rate was higher in the sarcopenia group than in the non-sarcopenia group (P = .002, P = .01). According to the PMI, patients with sarcopenia have an 8.17 times greater risk of exitus than non-sarcopenic patients. According to the HUAC, patients with sarcopenia have a 4.21 times greater risk of exitus than non-sarcopenic patients.

CONCLUSION

Based on this large retrospective study, sarcopenia is a strong and independent predictor of postoperative mortality after Fournier's treatment for gangrene.

Importance of emergency department waiting period in Fournier's Gangrene; 10 years of experience

BACKGROUND

Fournier's gangrene (FG) is a disease with high mortality rate. The first diagnosis is performed in the emergency department (ED). In this study, we investigated the importance of the time period for diagnosis in the ED.

METHODS

The data of patients who were treated for FG between 1 January 2010 and 2020 were retrospectively analysed. Waiting period of the patients in ED was calculated. Risk factor score calculations were calculated to predict FG mortality and prognosis. The effects of the ED waiting period on the duration of admission to the hospital, the number of debridements and mortality status and relationship with FG mortality risk factor scores were investigated.

RESULTS

In a 10-year period, a total of 66 patients were included in the study. It was found that the median age of the patients was 56 years. ED waiting period median (IQR) was 105 (115) minutes. It was observed that there was a significant positive correlation between the ED waiting period, duration of admission to hospital (rs: 0.537, P < .001) and patients mortality status (rs: 0.482, P < .001). The ED waiting period was higher in patients with FG mortality. It was observed that the ED waiting period holds a diagnostic value in predicting mortality (P < .001). The cut-off limit predicted for this value was determined as 136 minutes.

CONCLUSION

FG is a urological emergency. ED waiting period affects mortality rate and length of hospital stay. The earlier the diagnosis and treatment is conducted in the ED, the lower the mortality rate and length of stay in the hospital will be.

[Diagnosis and Treatment of Severe Fournier's Gangrene: Introduction of a Surgical Approach, Evaluation of Risk Factors, Microbiological Characteristics and Review of the Literature]

BACKGROUND

Fournier's gangrene is a necrotising fasciitis type I occurring in the perineal and genital region. The disease expands progressively and still has poor outcome, especially in critical ill patients. This study's focus was placed on the evaluation of risk factors and comorbidities, on the bacteriological spectrum, laboratory analyses, mortality and the course according to the algorithmic approach.

METHOD

The medical records were reviewed of 10 patients with severe Fournier's gangrene from 2010 to 2019 who underwent intensive care therapy for at least 48 hours. Ten patients with Fournier's gangrene and sepsis and intensive therapy lasting at least 48 hours were recorded and analysed descriptively.

RESULTS

The patient cohort consisted of six men and four women with a median age of 62 years (range 42 - 78 years). The median time between the onset of symptoms and hospitalisation was four days (range 3 - 5 days). The commonest aetiological event was a minor trauma. Predisposing factors included diabetes mellitus (30%) and overweight (80% BMI > 25). 90% of patients exhibited polymicrobial infection. All patients had systemic sepsis with SOFA-Score between 3 and 17 points. The mortality rate was 40%. Significant differences between surviving and deceased patients were shown by PCT, INR and aPTT (p < 0.05).

CONCLUSION

Severe Fournier's gangrene continues to be a major challenge with a high mortality rate. Only rapid diagnosis, urgent extensive surgical debridement and intensive care therapy can lead to a favourable outcome in these critically ill patients. Vacuum-assisted closure can be successfully used in the management of soft-tissue defects.

Fournier Gangrene in the Emergency Department: Diagnostic Dilemmas, Treatments and Current Perspectives

Fournier gangrene (FG) is a rare and life-threatening urosurgical emergency characterized most often by a polymicrobial infection of the perineal, genital, or perianal region. FG has an increased incidence in male patients, patients with alcoholism, and patients with immunocompromise including human immunodeficiency virus (HIV) and uncontrolled diabetes. FG often begins as a simple abscess or cellulitis with progression to necrotizing soft tissue infection (NSTI). Delays in diagnosis and treatment confer high mortality. Early recognition and high clinical suspicion are important in making a timely diagnosis, as early manifestations are often subtle. The most significant modifiable risk factor associated with NSTI mortality is delay to surgical intervention. Coordination of both inpatient medical and surgical teams to implement appropriate therapy is vital to successful outcomes. The emergency medicine clinician must be vigilant for this condition and be aware of risk factors, prognostic indicators, and proper treatment protocols to recognize FG early and initiate appropriate management. The objective of this review is to provide updated and relevant information regarding recognition, diagnosis, and management of FG for the emergency medicine provider.

Profile of patients with Fournier's gangrene and their clinical evolution

OBJECTIVE

to analyze the profile of patients with Fournier's gangrene treated in a public tertiary hospital in western Paraná State.

METHODS

we conducted a cross-sectional, retrospective and descriptive study of patients with Fournier's gangrene treated between January 2012 and November 2016.

RESULTS

there were 40 patients with Fournier's gangrene treated in the period, 29 (72.5%) men and 11 (27.5%) women. The mean age was 51.7±16.3 years. The mean time of disease progression, from the initial symptom to hospitalization, was 10.5±1.2 days. All patients had clinical signs such as pain, bulging, erythema, among others, and 38 (95%) had associated comorbidities, the most common being type 2 diabetes mellitus and systemic arterial hypertension. The majority (30 patients - 75%) had perianal abscess as the probable etiology. All patients were submitted to antibiotic therapy and surgical treatment, with a mean of 1.8±1.1 surgeries per patient. Nine (22.5%) patients died. There was a strong correlation between the presence of sepsis on admission and mortality.

CONCLUSION

Fournier's gangrene patients in this series had a long disease duration and a high prevalence of comorbidities, with a high mortality rate.

Prognostic factors and treatment outcomes for patients with Fournier's gangrene: a retrospective study

Fournier's gangrene is a gas-forming, necrotising soft tissue infection affecting the perineum. It spreads rapidly along the deep fascial planes and is associated with a high mortality rate. With a growing elderly population with comorbidities, the frequency of severe cases of Fournier's gangrene is expected to increase. We retrospectively reviewed 20 patients diagnosed with Fournier's gangrene at our institution from 2003 to 2014 and analysed data. Thirteen patients had diabetes mellitus, two had been diagnosed with liver cirrhosis, and four were chronic alcoholics. Of 15 patients admitted to an intensive care unit, 11 underwent colostomy, and 4 required skin grafts for wound healing. The wide wounds of two patients were healed using vacuum-assisted closure (VAC^® ) dressing without additional surgery. The mortality rate was 25%, and the patients whose Fournier's gangrene severity index (FGSI) score was higher than 9 points or whose blood urea nitrogen (BUN) level was higher than 50 mg/dl had a poor prognosis. In order to treat Fournier's gangrene, aggressive surgical treatment, including wide debridement and stoma creation, should be considered as soon as possible to improve survival rates. Additionally, VAC dressing is helpful in healing the wide debridement wound without additional reconstructive surgery.

Analysis of prognostic factors affecting mortality in Fournier's gangrene: A study of 72 cases

INTRODUCTION

Fournier's gangrene is a rapidly progressing necrotizing fasciitis of the perineum and genital area associated with a high mortality rate. We presented our experience in managing this entity and identified prognostic factors affecting mortality.

METHODS

We carried out a retrospective study of 72 patients treated for Fournier's gangrene at our institution between January 2005 and December 2014. Patients were divided into survivors and non-survivors and potential prognostic factors were analyzed.

RESULTS

Of the 72 patients, 64 were males (89%) and 8 females (11%), with a mean age of 51 years. The most common predisposing factor was diabetes mellitus (38%). The mortality rate was 17% (12 patients died). Statistically significant differences were not found in age, gender, and predisposing factors, except in heart disease (p = 0.038). Individual laboratory parameters significantly correlating with mortality included hemoglobin (p = 0.023), hematocrit (p = 0.019), serum urea (p = 0.009), creatinine (p = 0.042), and potassium (p = 0.026). Severe sepsis on admission and the extent of affected surface area also predicted higher mortality. Others factors, such as duration of symptoms before admission, number of surgical debridement, diverting colostomy and length of hospital stay, did not show significant differences. The median Fournier's Gangrene Severity Index (FGSI) was significantly higher in non-survivors (p = 0.002).

CONCLUSION

Fournier's gangrene is a severe surgical emergency requiring early diagnosis and aggressive therapy. Identification of prognostic factors is essential to establish an optimal treatment and to improve outcome. The FGSI is a simple and valid method for predicting disease severity and patient survival.

Predictive factors for mortality in Fournier' gangrene: a series of 59 cases

AIMS

Fournier's gangrene (FG) is the necrotizing fasciitis of the perineum and genital area and presents a high mortality rate. The aim was to assess prognostic factors for mortality, create a new mortality predictive scale and compare it with previously published scales in patients diagnosed with FG in our Emergency Department.

METHODS

Retrospective analysis study between 1998 and 2012.

RESULTS

Of the 59 patients, 44 survived (74%) (S) and 15 died (26%) (D). Significant differences were found in peripheral vasculopathy (S 5 [11%]; D 6 [40%]; P=.023), hemoglobin (S 13; D 11; P=.014), hematocrit (S 37; D 31.4; P=.009), white blood cells (S 17,400; D 23,800; P=.023), serum urea (S 58; D 102; P<.001), creatinine (S 1.1; D 1.9; P=.032), potassium (S 3.7; D 4.4; P=.012) and alkaline phosphatase (S 92; D 133; P=.014). Predictive scores: Charlson index (S 1; D 4; P=.013), severe sepsis criteria (S 16 [36%]; D 13 [86%]; P=.001), Fournier's gangrene severity index score (FGSIS) (S 4; D 7; P=.002) and Uludag Fournier's Gangrene Severity Index (UFGSI) (S 9; D 13; P=.004). Independent predictive factors were peripheral vasculopathy, serum potassium and severe sepsis criteria, and a model was created with an area under the ROC curve of 0.850 (0.760-0.973), higher than FGSIS (0.746 [0.601-0.981]) and UFGSI (0.760 [0.617-0.904]).

CONCLUSIONS

FG showed a high mortality rate. Independent predictive factors were peripheral vasculopathy, potassium and severe sepsis criteria creating a predictive model that performed better than those previously described.

Fournier's gangrene

Fournier's gangrene (FG) is a synergistic polymicrobial gangrenous infection of the perineum, scrotum and penis which is characterised by obliterative endarteritis of the subcutaneous arteries, resulting in gangrene of the subcutaneous tissue and the overlying skin. FG affects all ages and both genders, with a male preponderance. It is a rare but life-threatening disease, and despite therapeutic advances in recent years, the mortality rate is 3%-67%, with an incidence of 1:7500-1:750,000. Anorectal, genitourinary and cutaneous sources of infection are the most common causes of FG, with diabetes mellitus being the most common risk factor. The clinical condition presents evolution from 2 to 7 days and is characterised by uneasiness, local swelling and discomfort, fever, crepitus and sometimes frank septic shock. Current imaging techniques for initial evaluation of the disease include radiography, Ultrasonography (USG), Computed Tomography (CT) and Magnetic Resonance Imaging (MRI). However, the diagnosis of FG is usually clinical and imaging can be helpful in uncertain diagnosis and when clinical findings are ambiguous. Treatment of FG is based on a multimodal approach which includes intensive fluid resuscitation to stabilise the patient and correction of electrolyte imbalance, if any. This is followed by extensive debridements and resections in order to remove all necrotic and infected tissue, wide spectrum antibiotics and reconstructive surgery, whenever required. However, despite all the advances in treatment today, FG remains a surgical emergency, hence, early recognition with aggressive haemodynamic stabilisation, parenteral broad spectrum antibiotics and urgent surgical debridement are the mainstay of treatment.

Treatment of two cases of Fournier's gangrene and review of the literature

Fournier's gangrene is a rare polymicrobial necrotising soft tissue infection affecting the perineum and scrotum. It is rapidly progressive, destructive and associated with high morbidity and mortality. Management protocol includes prompt diagnosis, early institution of antibiotic therapy and adequate wound debridement, usually requiring multiple operations. Rapid accurate diagnosis is crucial for successful outcome, while early aggressive surgical intervention together with fluid, hemodynamic and nutritional support and broad-spectrum antibiotics are essential to reduce mortality. Dermatologists are often the first specialist consulted. Two cases of Fournier's gangrene are reported in this report. The aim of the report is to underline the importance of an immediate diagnostic approach to save patients, favoured by a close collaboration among dermatologist, surgeon and urologist.

Fournier gangrene: description of 37 cases and analysis of associated health care costs

BACKGROUND AND OBJECTIVES

Fournier gangrene is a urological emergency associated with a high mortality. It is a necrotizing fasciitis caused by polymicrobial infection originating in the anorectal or genitourinary area. The aim of this study was to analyze the epidemiological and clinical characteristics of Fournier gangrene along with the variables that influence disease course and mortality in patients treated in our department.

MATERIAL AND METHODS

We carried out a retrospective study of 37 patients diagnosed with Fournier gangrene between January 2001 and October 2010.

RESULTS

All the patients were men, 43.2% had diabetes, and the mean age of the patients was 57.68 years. Statistically significant differences were observed between the age of surviving patients and that of patients who died (55.8 and 69.6 years, respectively). The mean hospital stay was 27.54 days and 32.4% of patients required admission to the intensive care unit. Etiology was unknown in 39.8% of cases. Polymicrobial infection was observed in 59.5% of cases. The mean health care cost associated with a patient diagnosed with Fournier gangrene admitted to intensive care and requiring at least 1 procedure in the operating room was €25,108.67. Mortality was 13.5%. Based on analysis of individual comorbid conditions, only ischemic heart disease displayed a statistically significant association with mortality due to Fournier gangrene; ischemic heart disease was also associated with longer hospital stay.

CONCLUSIONS

Fournier gangrene is associated with high mortality despite appropriate early treatment. Although the condition is infrequent, the high associated health care costs suggest that primary and secondary prevention measures should be implemented.
