Predisposing factors and treatment outcome in Fournier's gangrene. Analysis of 28 cases

A Comprehensive Literature Review of Fournier's Gangrene in Females

Fournier gangrene (FG) is a rare but rapidly progressing disease with a higher mortality rate in women as compared to men. This study aims to perform a literature review about FG in females and associated mortality and morbidity. We searched databases including MEDLINE (Ovid), the National Library of Medicine (Medical Subject Headings (MeSH)), the Cochrane Database of Systematic Reviews (Wiley), as well as Embase (Ovid), Scopus, and Global Index Medicus (WHO), and reviewed literature from 2002 to 2022 and selected 22 studies that met our study's inclusion criteria, which included 134 female patients with a mean age of 55±6 years. The perineal abscess was a more common nidus (n=41, 35%; 95%CI 23-39%) than vulvar pathology (n=29, 22%; 95%CI 15-30%). The most common initial presentation was cellulitis (n=62, 46%; 95%CI 38-55%), followed by perineal pain (n=54, 40%; 95%CI 32-50%), fever (n=47, 35%; 95%CI 27-43%), and septic shock (n=38, 28%; 95%CI 21-37%). Escherichia coli was the most frequently identified bacteria (n=48, 36%; 95%CI 28-46%). All patients had treatment with a mean of three (SD 2) debridement and those with negative pressure dressings received fewer debridements than those who received a conventional dressing. However, of those who had surgical intervention, 28 (20%; 95%CI 14-29%) patients underwent diversion colostomy. General surgeons performed 78% (n=104) of cases out of which 20% (n=20) were consulted by obstetrician-gynecologists, 14% (n=18) were treated by urologists, and only 8% (n=10) by plastic surgeons. The mean length of stay in the hospital was 24±11 days, and the gross mortality rate was 27 (20%; 95%CI 14-28%). In conclusion, while females have a low incidence rate of FG, they carry a higher mortality rate. Lack of cardinal signs and delayed presentation to the hospital from the onset of symptoms are some possible causes for the increased mortality rate along with the disease process being under-recognized in women. A high index of clinical suspicion is essential to avoid delay in the definitive management coupled with an early surgical consult and establishing a common general care pathway could minimize mortality and morbidity.

Factors affecting length of stay in Fournier's gangrene: a retrospective analysis of 10 years' data

BACKGROUND

We aimed to investigate the parameters that have an effect on the length of stay and mortality rates of patients with Fournier's gangrene.

MATERIAL AND METHODS

A retrospective review was performed on 80 patients who presented to the emergency department and underwent emergency debridement with the diagnosis of Fournier's gangrene between 2008 and 2017. The demographic and clinical characteristics, length of stay, Fournier's Gangrene Severity Index score, cystostomy and colostomy requirement, additional treatment for wound healing and the mortality rates of the patients were evaluated.

RESULTS

Of the 80 patients included in the study, 65 (81.2 %) were male and 15 (18.7 %) female. The most common comorbidity was diabetes mellitus. The mean time between onset of complaints and admission to hospital was 4.6 ± 2.5 days. As a result of the statistical analyses, it was found that Fournier's Gangrene Severity Index score, hyperbaric oxygen therapy, negative pressure wound therapy and the presence of sepsis and colostomy were significantly positively correlated with length of stay. Also it was found that the Fournier's Gangrene Severity Index score, administration of negative pressure wound therapy and the presence of sepsis were correlated with mortality.

CONCLUSION

Fournier's gangrene is a mortal disease and an emergency condition. With the improvements in Fournier's gangrene disease management, mortality rates are decreasing, but long-term hospital stay has become a new problem. Knowing the values predicting length of stay and mortality rates can allow for patient-based treatment and may be useful in treatment choice.

Anorectal emergencies: WSES-AAST guidelines

Anorectal emergencies comprise a wide variety of diseases that share common symptoms, i.e., anorectal pain or bleeding and might require immediate management. While most of the underlying conditions do not need inpatient management, some of them could be life-threatening and need prompt recognition and treatment. It is well known that an incorrect diagnosis is frequent for anorectal diseases and that a delayed diagnosis is related to an impaired outcome. This paper aims to improve the knowledge and the awareness on this specific topic and to provide a useful tool for every physician dealing with anorectal emergencies.The present guidelines have been developed according to the GRADE methodology. To create these guidelines, a panel of experts was designed and charged by the boards of the World Society of Emergency Surgery (WSES) and American Association for the Surgery of Trauma (AAST) to perform a systematic review of the available literature and to provide evidence-based statements with immediate practical application. All the statements were presented and discussed during the WSES-AAST-WJES Consensus Conference on Anorectal Emergencies, and for each statement, a consensus among the WSES-AAST panel of experts was reached. We structured our work into seven main topics to cover the entire management of patients with anorectal emergencies and to provide an up-to-date, easy-to-use tool that can help physicians and surgeons during the decision-making process.

Relationship between diversional stoma and mortality rate in Fournier's gangrene: a systematic review and meta-analysis

PURPOSE

Fournier's gangrene (FG) is a rare potentially lethal necrotising infection of the perineum. While the gold standard management is early and aggressive surgical debridement, the evidence in the literature is unclear as to the role and outcomes of diversional stoma.

METHODS

A systematic review was conducted to identify studies investigating the relationship between stoma formation and FG. Meta-analyses were performed using a random-effects model.

RESULTS

Twenty-seven studies (n=1482) were included. There was no significant difference in disease severity scores between the stoma and no stoma groups. Mortality rate was significantly higher in patients who required diversional stoma (OR 1.71, 95% CI 1.13-2.59, p=0.01). Significantly more surgical procedures were performed on patients who underwent stoma formation, and the total hospital cost was also higher in this group. This study may have been limited by bias in patients with more fulminant course or sphincter damage requiring stoma as a medical necessity.

CONCLUSION

These findings suggest that the use of diversional stoma in FG is a predictor of poor outcomes. This study demonstrated that mortality rate remained high and a diversional stoma did not reduce risk of mortality as suggested by smaller case series. Its use should therefore be individualised based on disease severity and sphincter damage.

[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: pictorial review

Fournier gangrene is an emergency condition that is associated with a high mortality rate. It is defined as a rapidly progressing infective necrotizing fasciitis of the perineal, perianal, and genital regions. Early diagnosis, broad-spectrum antibiotic coverage, and adequate surgical debridement are crucial and lead to better prognosis and patient survival. There is increasing utilization of computed tomography (CT) in the initial evaluation of Fournier gangrene. CT can confirm the diagnosis in equivocal cases, determine the source of infection, and evaluate the disease extent. In this pictorial review, we discuss the pathogenesis of Fournier gangrene and display the imaging spectrum with an emphasis on CT findings, including asymmetrical fascial thickening, soft tissue stranding, soft tissue gas, collection, and abscess formation. The infection originating from colorectal pathology, the affected anatomy, and the involvement of the abdominal wall are important predictors of mortality. The familiarity of the varied imaging appearance of Fournier gangrene is necessary to provide an accurate diagnosis, and evaluation of disease extent is crucial for optimal surgical debridement.

Fournier Gangrene in Men and Women: Appearance on CT, Ultrasound, and MRI and What the Surgeon Wants to Know

Fournier gangrene (FG) is a genitourinary necrotizing fasciitis that can be lethal if not promptly diagnosed and surgically debrided. The diagnosis is often made by physical examination paired with an appropriate clinical suspicion and supporting laboratory values. Imaging, particularly computed tomography (CT), plays a role in delineating involved fascial planes for operative debridement and occasionally in diagnosing FG. Less commonly, the imaging manifestations of FG may also be seen on ultrasound, radiographs, and magnetic resonance imaging. With the ubiquitous use and availability of CT, radiologists have a growing role in recognizing FG. This can be challenging in the absence of fascial gas, but a CT scoring system for necrotizing fasciitis can be helpful in making the diagnosis. Recent series suggest that this predominantly male disease has a rising incidence in women. Women with FG are more likely to be morbidly obese and have vulvar or labial involvement compared to men. Imaging mimics include ulcerative and necrotic tumors, traumatic or iatrogenic fascial gas, and vaginitis emphysematosa. The purpose of this pictorial review is to illustrate the imaging manifestations of FG and its mimics, with emphases on necrotizing fasciitis CT scoring systems and FG in women.

Which Method Is Better to Provide Wound Healing in Fournier Gangrene: Dakin Solution or Conventional Antiseptic Dressings? A Retrospective Study

Fournier gangrene is described as necrotizing fasciitis involving the genital, perineal, and perianal area. Early surgical debridement of necrotic tissues, topical therapy, and antibiotics are fundamental in the treatment of Fournier gangrene. We aimed to compare the effects of Dakin solution and povidone iodine solution on patient outcomes by using the Fournier gangrene severity index (FGSI). The demographic data, comorbid diseases, local therapeutic interventions, FGSI, necessity of diverting colostomy or orchiectomy, hospitalization time, number of debridements, complications, and outcomes of 57 patients with Fournier gangrene were retrospectively analyzed. A total of 47 of 57 patients (82.5%) were male, and 10 patients (17.5%) were female, with a mean age of 62.3 ± 13.8 years (range, 27–85 years). The survivors were significantly younger than the nonsurvivors. The mean FGSI score was 4 (range, 1–9) in survivors, and mean FGSI score was 9 (range, 6–10) in nonsurvivors. FGSI score was significantly higher in the mortality group. The median hospital stay was 13 days (range, 3–34 days) in the Dakin solution group and 20 days (range, 1–41 days) in the povidone iodine group. Overall mortality rate was 17.5%. Advanced age had a statistically significant effect on mortality. The hospitalization time was significantly shorter in the Dakin solution group, and use of Dakin solution decreased the number of debridements. Dakin solution has favorable effects on hospital stay and the necessity of multiple debridements. Dakin solution seems to be a good and cost-effective choice for treatment in local wound healing.

Preoperative CT Findings and Interobserver Reliability of Fournier Gangrene

OBJECTIVE

The objective of our study was to delineate CT findings and anatomic areas of involvement of surgically proven Fournier gangrene (FG) and determine interobserver reliability.

MATERIALS AND METHODS

This study was a single-center retrospective study of patients with FG who underwent CT before surgical débridement of FG during a 9-year period. Thirty-eight patients with FG, 17 male and 21 female patients, underwent preoperative CT. Two radiologists reviewed the CT studies and recorded findings and anatomic areas of involvement. CT findings were categorized according to a previously described CT scoring system for necrotizing fasciitis and included the presence or absence of fascial air, muscle or fascial edema, fluid tracking, lymphadenopathy, and subcutaneous edema. Cohen kappa was calculated for interobserver reliability.

RESULTS

Mean body mass index (BMI [weight in kilograms divided by height in meters squared]) was 42, and 22 of 38 (58%) patients had diabetes. Mean BMI and proportion of patients with diabetes were significantly higher in female patients (mean BMI = 46; 16/21 with diabetes) than male patients (mean BMI = 36; 6/17 with diabetes). CT studies of most patients showed fascial air (36/38 [95%], both readers 1 and 2). Interobserver reliability was substantial to almost perfect for all CT findings except lymphadenopathy, for which it was fair (κ = 0.37). Genital, perineal, and ischiorectal involvement were seen in 87% (33/38), 87% (33/38), and 32% (12/38) of patients for reader 1 and 84% (32/38), 84% (32/38), and 26% (10/38) of patients for reader 2 (κ = 0.29, penis; κ = 0.65, scrotum; κ = 0.91, vulva and labia; κ = 0.68, perineal involvement; κ = 0.80, ischiorectal involvement).

CONCLUSION

Most CT findings of FG and anatomic areas of involvement showed good interobserver reliability. A high proportion of female patients with FG were observed in this study compared with prior series.

Successful treatment following early recognition of a case of Fournier's scrotal gangrene after a perianal abscess debridement: a case report

Background

Fournier’s gangrene is an acute surgical emergency characterized by high mortality rates ranging from approximately 13% to 45%. Therefore, aggressive multidisciplinary management is necessary.

Case presentation

A 29-year-old Asian man who had undergone surgical debridement at another hospital to treat a perianal abscess 5 days earlier was admitted to our hospital for severe scrotal and perianal pain, swelling, and high fever. A physical examination revealed a perianal abscess. Furthermore, the scrotum was gangrenous and exhibited extensive cellulitis in the perineum and bilateral inguinal area. Crepitations between the skin and fascia were palpable. A diagnosis of Fournier’s gangrene was made. The patient was treated with immediate surgical debridement under general anesthesia. He received broad-spectrum antibiotics, and debridement was repeated until the wound exhibited healthy granulation. Because both testes were severely exposed, they were transpositioned back into the scrotum 1 week after surgery. The patient was discharged on the 11th postoperative day.

Conclusions

The mainstay of treatment for Fournier’s gangrene should include fluid resuscitation, broad-spectrum antibiotic therapy, intensive care, nutritional support, and early aggressive surgical debridement of all necrotic tissue.

Peri-vulvar reconstruction using internal pudendal artery perforator flap in female Fournier's gangrene

Fournier's gangrene in female patients has low incidence rate but high mortality rate compared with that in males, with many cases resulting in death at acute phase. This is due to the differences in male and female genital anatomy, which should be fully understood by physicians to increase the patient's survival rate. After crossing the acute phase of the disease by an appropriate treatment, it is important to reconstruct vaginal or vulvar defects according to the patient's three-dimensional anatomical structures. Perforator flap based on internal pudendal artery is one of the ideal reconstructive techniques to resolve the aforementioned issue. The authors intend to introduce the distinguishing characteristics of Fournier's gangrene in female patients, and the surgical techniques to reconstruct the defects after the acute phase of disease.

Overview of different scoring systems in Fournier's Gangrene and assessment of prognostic factors

OBJECTIVE

In this study we aimed to evaluate prognostic factors for the survival of patients with Fournier's gangrene (FG), and overview different validated scoring systems for outcome prediction.

MATERIAL AND METHODS

We retrospectively analyzed the data of 39 patients treated for FG in our clinic. Data were collected on medical history, symptoms, physical examination findings, vital signs, laboratory parameters at admission and at the end of treatment, timing and extent of surgical debridement, and the antibiotic treatment used. The Fournier's Gangrene Severity Index (FGSI) and Charlson Comorbidity Index (CCI) were used to predict outcome. The data were analyzed in relation with the survival of the patients. Mann-Whitney U test, chi -square test, Wilcoxon signed rank test, and Cox regression analysis were used for the statistical analysis.

RESULTS

Of 39 patients analyzed, 8 (20.5%) died and 31 (79.5%) survived. The median FGSI score on admission was 2 (0-9) for the survivors and 6 (2-14) for the non-survivors (p=0.004). The median CCI scores of the survivors and non-survivors were 2 (0-10) and 6.5 (5-11), respectively (p=0.001). Except for urea, albumin and hematocrit levels, no significant differences were found between survivors and non-survivors for other laboratory parameters on admission. Lower albumin levels and advanced age were found to be associated with mortality.

CONCLUSION

High blood urea, low albumin, and low hematocrit levels were associated with poor prognosis. High CCI and FGSI scores could be associated with a poor prognosis in patients with FG.

Evaluation of LRINEC Scale Feasibility for Predicting Outcomes of Fournier Gangrene

BACKGROUND

Fournier gangrene (FG) is a fulminant necrotizing infection of the perineal, perianal, and periurethral tissues. The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) scale is used for diagnosis of necrotizing fasciitis. However, data on its relevance and usefulness in FG are lacking. The aim of this study was to evaluate the utility of the LRINEC scale in predicting the outcome of FG.

METHODS

This retrospective case study included 41 patents with FG treated at our institution from 2000 to 2013. The patients were divided into survivors and non-survivors.

RESULTS

The mortality rate was 22%. The median age (75 vs. 62.5 y; p = 0.013), rate of co-existing diabetes mellitus (66.7% vs. 3.1%; p < 0.001), and median affected skin surface (4% vs. 1%; p < 0.001) were greater in the non-survivors. Seven of nine patients (77.8%) who did not survive (compared with 37.5% who survived) had a polymicrobial infection (p = 0.032). Of all the causative pathogens isolated, Proteus mirabilis was more common in non-survivors (55.6% vs. 6.3%; p = 0.001). The median calculated LRINEC score for survivors was 5 compared with 10 for the non-survivors (p < 0.001). Regression analysis showed that all the aforementioned variables, except for polymicrobial culture, were significant risk factors for predicting death. The area under the receiver operating characteristic curve for the LRINEC score was the highest, 0.976 (95% confidence interval 0.872-0.999; p < 0.0001), and the cut-off value was ≥9 with 93.7% specificity and 100% susceptibility for the prediction of a lethal outcome.

CONCLUSIONS

The LRINEC score could be used for prediction of disease severity and outcomes. A threshold of 9 could be a high-value predictor of death during the initial evaluation of patients with FG.

Contemporary diagnosis and management of Fournier's gangrene

Fournier's gangrene, an obliterative endarteritis of the subcutaneous arteries resulting in gangrene of the overlying skin, is a rare but severe infective necrotizing fasciitis of the external genitalia. Mainly associated with men and those over the age of 50, Fournier's gangrene has been shown to have a predilection for patients with diabetes as well as people who are long-term alcohol misusers. The nidus for the synergistic polymicrobial infection is usually located in the genitourinary tract, lower gastointestinal tract or skin. Early diagnosis remains imperative as rapid progression of the gangrene can lead to multiorgan failure and death. The diagnosis is often made clinically, although radiography can be helpful when the diagnosis or the extent of the disease is difficult to discern. The Laboratory Risk Indicator for Necrotizing Fasciitis score can be used to stratify patients into low, moderate or high risk and the Fournier's Gangrene Severity Index (FGSI) can also be used to determine the severity and prognosis of Fournier's gangrene. Mainstays of treatment include rapid and aggressive surgical debridement of necrotized tissue, hemodynamic support with urgent resuscitation with fluids, and broad-spectrum parental antibiotics. After initial radical debridement, open wounds are generally managed with sterile dressings and negative-pressure wound therapy. In cases of severe perineal involvement, colostomy has been used for fecal diversion or alternatively, the Flexi-Seal Fecal Management System can be utilized to prevent fecal contamination of the wound. After extensive debridement, many patients sustain significant defects of the skin and soft tissue, creating a need for reconstructive surgery for satisfactory functional and cosmetic results.

Fournier gangrene in pregnancy

BACKGROUND

Fournier gangrene is a rare and rapidly progressive necrosis of the perineal and genitourinary region. Although predominantly affecting men, we describe an unusual presentation in pregnancy.

CASE

A 30-year old primigravid woman in the third trimester of pregnancy presented with a history of low back pain. Subsequently, a diagnosis of perianal sepsis and associated Fournier gangrene was established. The patient underwent an emergency cesarean delivery followed by radical surgical debridement and colostomy.

CONCLUSION

Expedited delivery, timely diagnosis of gangrene, urgent, extensive debridement, and broad-spectrum antibiotic coverage contributed largely to effective management of this rare presentation in pregnancy.

Epidemiological characteristics of Fournier's gangrene: a report of 71 patients

INTRODUCTION

To identify the predisposing factors, etiological and clinical characteristics as well as the Fournier's gangrene (FG) severity index (FGSI) in the outcomes of patients with FG.

MATERIALS AND METHODS

The data from 71 patients diagnosed with FG in a period of 17 years were retrospectively reviewed for the age of the patient, their history, predisposing factors, etiology, prodromal symptoms, FGSI, culture results, hospitalization period, surgical interventions, responses to the therapy and complications.

RESULTS

All of the patients were Caucasian males, and the mean age was 61.3 (range 36-92) years. The mean duration from the onset of symptoms to surgery was 7.5 days. The mean hospitalization time was 27.4 days and the most common etiological factor for FG was a perineal abscess. The overall mortality rate was 29.6%. The relationship between the number of predisposing factors and mortality rates in patients with FG was the most statistically significant parameter (p = 0.001).

CONCLUSIONS

Multiple predisposing factors predict a poor prognosis and correlate significantly with mortality. Extension of the disease and the FGSI score were not predictive of outcome. The most essential intervention for stopping the rapidly progressing infectious process of FG consists of early recognition of the disease, proper management of the predisposing factors and aggressive surgical debridement. Such an intervention can improve clinical outcomes.

Fournier's Gangrene: Conventional Dressings versus Dressings with Dakin's Solution

Purpose. Fournier's gangrene is a fulminant and destructive inflammation of the scrotum, penis, and perineum. The objective of this study was to compare 2 different approaches to wound management after aggressive surgical debridement. Methods. Data from 14 patients with Fournier's gangrene were retrospectively collected (2005–2011). Once the patients were stabilized following surgery, they were treated with either daily antiseptic (povidone iodine) dressings (group I, n = 6) or dressings with dakin's solution (sodium hypochloride) (group II, n = 8). Results. The mean age of the patients was 68.2 ± 7.8 (55–75) years in group I and 66.9 ± 10.2 (51–79) years in group II. Length of hospital stay was 13 ± 3.5 (7–16) days in group I and 8.9 ± 3.0 (4–12) days in group II (P < 0.05). The number and rate of mortality was 1/6 (16.7%) in group I, and 1/8 (12.5%) in group II. Conclusions. The hospitalization time can be reduced with the use of dakin's solution for the dressings in the treatment of FG. Also, dressings with dakin's solution seems to have favorable effects on morbidity and mortality. Consequently dakin's solution may alter the treatment of this disastrous disease by reducing cost, morbidity and mortality.

Gangrène des organes génitaux externes (GOGE): traitement chirurgical et reconstruction plastique

Buts

Présenter notre contribution à la reconstruction chirurgicale de la gangrène des organes génitaux externes (GOGE), selon les lésions.

Matériel et méthodes

Il s’agit d’une étude rétroprospective, portant sur 14 patients traités et guéris dans le service d’urologie du CHU de Cocody à Abidjan, de GOGE entre janvier 2000 et juin 2009.

Résultats

L’âge moyen des patients était de 39 (20–67) ans. Tous étaient des hommes de race noire. Ils présentaient tous un tableau infectieux traité par une réanimation hydroélectrolytique et une triantibiothérapie. Les lésions cutanées observées intéressaient les organes génitaux externes (OGE) dans neuf cas (64,29 %), puis le scrotum et le périnée dans cinq cas (35,71 %). Toutes les lésions cutanées ont été décapées, suivies de pansements locaux. Ainsi, 14 patients (100 %) ont été guéris, complètement cicatrisés, dont trois cas (21,43 %) de lésions scrotales minimes qui ont cicatrisé spontanément à la suite de pansement uniquement, neuf patients (64,29 %) ont cicatrisé à la suite de suture sans tension de la peau scrotale après débridement, décollement, enfin deux patients (14,28 %) avaient cicatrisé après une greffe de peau mince prélevée à la face interne de la cuisse pour plaie périnéopénoscrotale étendue, d’une part, et, d’autre part, pour une perte complète du fourreau pénien. Conclusion: La GOGE est une affection grave, qui réalise, d’une part, une toxi-infection traitée par une réanimation et une triantibiothérapie, d’autre part, des lésions cutanées plus ou moins étendues nécessitant débridement, décapage, pansement, puis une reconstruction chirurgicale plastique qui restaure un environnement pénoscrotal adéquat qui ne compromette pas la qualité des rapports sexuels ainsi que la fonction de reproduction des testicules, surtout chez le sujet jeune.

[Group a streptococcal necrotizing fasciitis of the genital area (Fournier's gangrene): a case report]

A necrotizing fasciitis especially caused by group A streptococcal infection is a life-threatening disease. This infection cause death due to septic shock and multiple organ failure in a short time without the immediate and adequate treatment. Currently a rapid test kit for streptococcal pharyngitis (strep A) is useful for prediction of group A streptococcal infection. We here demonstrate a 61 years old man's case of life-saved necrotizing fasciitis in genital area (Fournier's gangrene) by group A streptococcus infection, and usefulness of this kit for rapid diagnosis, aggressive debridement, and selection of adequate antibiotics.

Is intensive multimodality therapy the best treatment for fournier gangrene? Evaluation of clinical outcome and survival rate of 41 patients

BACKGROUND

To evaluate the effect of surgical wound debridement, antibiotics, and hyperbaric oxygen (HBO) in the treatment of Fournier gangrene (FG).

METHODS

Forty-one patients with a mean age of 54.3±14.6 years were referred to our department with a diagnosis of FG. To calculate a Fourier Gangrene Severity Index (FGSI), nine factors were assessed (temperature; heart rate; ventilatory rate; serum sodium, potassium, creatinine, and bicarbonate concentrations; hematocrit; and leukocyte count). After clinical stabilization, extensive debridement of the necrotic tissue was performed, and a surgical vacuum-assisted closure (V.A.C.®) device was applied. Hyperbaric oxygen was administered; medical therapy consisted of intravenous antibiotics, electrolyte replacement, and parenteral nutrition.

RESULTS

Intraoperative cultures revealed Escherichia coli in 27 patients (66%), Pseudomonas aeruginosa in 28 (68%), gram-positive cocci in 24 (59%), and mixed flora (aerobic and anaerobic bacteria) in 39 (95%). One month after primary debridement, wound granulation was sufficient for plastic surgical reconstruction in all patients.

CONCLUSION

Because of the rapid worsening of FG, early diagnosis and immediate, aggressive multi-modality therapy with surgical debridement and broad-spectrum empiric antibiotics is crucial. The utility of HBO remains unproved.

Pressure sores significantly increase the risk of developing a Fournier's gangrene in patients with spinal cord injury

STUDY DESIGN

Retrospective chart review.

OBJECTIVES

The aim of our study was to evaluate the mortality rate and further specific risk factors for Fournier's gangrene in patients with spinal cord injury (SCI).

SETTING

Division of Spinal Cord Injury, BG-University Hospital Bergmannsheil Bochum, Ruhr-University Bochum, Germany.

METHODS

All patients with a SCI and a Fournier's gangrene treated in our hospital were enrolled in this study. Following parameters were taken form patients medical records: age, type of SCI, cause of Fournier's gangrene, number of surgical debridements, length of hospital and intensive care unit stay, co morbidity factors and mortality rate. In addition, laboratory parameter including the laboratory risk indicator for necrotizing fasciitis (LRINEC) score and microbiological findings were analyzed. Clinical diagnosis was made via histological examination.

RESULTS

A total of 16 male patients (15 paraplegic and one tetraplegic) were included in the study. In 81% of all cases, the origin of Fournier's gangrene was a pressure sore. The median LRINEC score on admission was 6.5. In the vast majority of cases, a polybacterial infection was found. No patient died during the hospital stay. The mean number of surgical debridements before soft tissue closure was 1.9 and after a mean time interval of 39.1 days wound closure was performed in all patients.

CONCLUSIONS

Pressure sores significantly increase the risk of developing Fournier's gangrene in patients with SCI. We reported the results of our patients to increase awareness among physicians and training staff working with patients with a SCI in order to expedite the diagnosis.

[Hyperbaric oxygen therapy adjunctive to surgical debridement in management of Fournier's gangrene: usefulness of a severity index score in predicting disease gravity and patient survival]

INTRODUCTION

Hyperbaric oxygen therapy (HBOT) concomitant to surgery has been reported to reduce Fournier's gangrene (FG) mortality compared to exclusive surgical debridement. Most report from centers with relatively few patients using only surgical procedure. To assess efficiency of aggressive debridement with adjunctive HBOT. To evaluate Fournier's gangrene severity score index (FGSI) predictive value.

MATERIAL AND METHODS

70 Fournier's gangrene (FG) treated by surgical debridement and HBOT. Data were evaluated physical examination findings, admission and final laboratory tests, surgical debridement extent, and antibiotic used. Patients had adjunctive (HBOT). FGSI, developed to assign a score describing the acuity of disease, was used. This index presents patients' vital signs, metabolic parameters (sodium, potassium, creatinine, and bicarbonate levels, and white blood cell count) and computes a score relating to the severity of disease at that time. Data were assessed according to whether the patient survived or died. All patients underwent surgical debridement. Wound debridement was regularly performed in the post operative period.

RESULTS

Of 70 patients, 8 died (11.4%) and 62 survived (88.5%). Difference in age between survivors (median age, 50.0 yr) and non survivors (median age, 54.5 yr) was not significant (p=0.321). Median extent of body surface area involved in necrotizing process in patients who survived and did not survive was 2.4% and 4.9%, respectively (p=0.001). Except for albumin, no significant differences were found between survivors and nonsurvivors. Median admission FGSI scores for survivors and non survivors were 2.1±2.0 and 4.2±3.8, (p=0.331).

CONCLUSION

FGSI score did not predict disease severity and the patient's survival. Metabolic aberrations, extent of disease seemed to be important risk factors for predicting FG severity and patient survival.

Successful Treatment of a Severe Case of Fournier's Gangrene Complicating a Perianal Abscess

A 67-year-old male patient with diabetes mellitus and nephritic syndrome under cortisone treatment was admitted to our hospital with fever and severe perianal pain. Upon physical examination, a perianal abscess was identified. Furthermore, the scrotum was gangrenous with extensive cellulitis of the perineum and left lower abdominal wall. Crepitations between the skin and fascia were palpable. A diagnosis of Fournier's gangrene was made. He was treated with immediate extensive surgical debridement under general anesthesia. The patient received broad-spectrum antibiotics, and repeated extensive debridements were performed until healthy granulation was present in the wound. Due to the fact that his left testicle was severely exposed, it was transpositioned into a subcutaneous pocket in the inner side of the left thigh. He was finally discharged on the 57th postoperative day. Fournier's gangrene is characterized by high mortality rates, ranging from 15% to 50% and is an acute surgical emergency. The mainstay of treatment should be open drainage and early aggressive surgical debridement of all necrotic tissue, followed by broad-spectrum antibiotics therapy.

New insights into the epidemiology and etiology of Fournier's gangrene: a review of 33 patients

BACKGROUND

Fournier's gangrene is a necrotizing fasciitis involving the perineal and genital regions. Even today, this often polymicrobial infection still carries a high mortality rate and continues to be a major challenge to the medical community. The purpose of this study was to report our experience with this condition and to compare it with those reported in published studies. We also introduce our approach to treatment.

METHODS

We analyzed data from 33 patients with Fournier's gangrene who were managed in our hospital from 1996 to 2007, focusing on patient gender, age, etiology, predisposing conditions, comorbidities, bacteriology, sepsis, blood results, mortality, and spread of gangrene.

RESULTS

18 (54.5%) of the 33 patients had been referred to our department by smaller district hospitals. The patient cohort consisted of 23 men and ten women with a median age of 59 years (range 40-79 years). The median time between the onset of symptoms and progression to gangrene was 6 days (range 2-28 days). An underlying cause was identified in 27 patients (81.8%). The commonest etiological events were perianal and perirectal abscesses (n = 13; 39.4%). Predisposing factors included diabetes mellitus in 12 cases (36.4%), chronic alcoholism in ten cases (30.3%), immunosuppression in six cases (18.2%), and prolonged immobilization in five cases (15.2%). 17 patients (51.5%) had a body mass index (BMI) of 25 or higher, and 13 patients (39.4%) had a BMI of 30 or higher. Positive cultures were obtained in 30 cases (90.9%). In 26 cases (78.8%), multiple microorganisms were recovered, including nine cases (27.3%) with both aerobes and anaerobes. Sepsis was present in 26 patients (78.8%). The mortality rate was 18.2%.

CONCLUSION

Fournier's gangrene remains a major challenge with a high mortality. Our results suggest that women are more commonly affected than has generally been assumed. Contrary to published reports, we found that anorectal sources appear to account for more cases of Fournier's gangrene than urological sources.

Fournier's gangrene: vacuum-assisted closure versus conventional dressings

BACKGROUND

Fournier's gangrene is a fulminant and destructive inflammation of the scrotum, penis, and perineum. The objective of this study was to compare 2 different approaches to wound management after aggressive surgical debridement.

METHODS

Data from 35 patients with Fournier's gangrene were prospectively collected (1996-2007). Once the patients were stabilized following surgery, they were treated with either daily antiseptic (polyhexanide) dressings (group I, n = 16) or vacuum-assisted closure (VAC) therapy (group II, n = 19).

RESULTS

The mean age of the patients was 58.2 years in group I and 57.2 years in group II. In both groups, the most common predisposing conditions were diabetes mellitus, chronic alcoholism, and obesity. Escherichia coli, streptococcal species, Pseudomonas aeruginosa, and Staphylococcus aureus were the most frequently isolated organisms. Length of hospital stay was 27.8 days +/- 27.6 days (mortality: 37.5%) in group I and 96.8 days +/- 77.2 days (mortality: 5.3%) in group II. Enterostomies were performed in 43.8% of group I patients and in 89.5% of group II patients.

CONCLUSIONS

VAC was associated with significantly longer hospitalization and lower mortality. A partial explanation is that some patients with severe sepsis died within the first 3 days after admission and thus could not undergo vacuum therapy. Since our clinical experience has shown that vacuum dressings are particularly effective in the management of large wounds, we use VAC primarily for this indication despite the considerable material requirements involved.

Fournier's gangrene: is the female gender a risk factor?

OBJECTIVE

Fournier's gangrene is a necrotizing fasciitis that affects the perineal, genital, or perianal regions. The objective of this study was to highlight this uncommon condition with a particular focus on the disease course in females.

MATERIALS AND METHODS

From 1996 to 2008, we prospectively collected data from 38 patients with Fournier's gangrene (12 women, 26 men) and retrospectively analyzed relevant parameters.

RESULTS

The mean age was 60.9 +/- 11.3 years for females (group I) and 56.2 +/- 11.7 years for males (group II). In both groups, the main predisposing factors were diabetes mellitus and obesity (body mass index of 30 or higher). Twelve men (46.2%), but no women, had chronic alcoholism. The most commonly isolated agents were Escherichia coli (n = 22), streptococcal species (n = 18), Pseudomonas aeruginosa (n = 9), and Staphylococcus aureus (n = 7). Mortality was significantly higher among females (50%) than males (7.7%; p = 0.011). Peritonitis was present in seven group I patients (58.3%) and in two group II patients (7.7%). The retroperitoneum was involved in seven female patients (58.3%) and four male patients (15.4%).

CONCLUSION

The female gender is a risk factor for mortality in patients with Fournier's gangrene and is associated with a higher incidence of inflammation of the retroperitoneal space and abdominal cavity. Differences in male and female genital anatomy may be the reason for the rapid spread of infection to the retroperitoneum and the fatal outcome in women. Fournier's gangrene as a high-risk disease in females should attract exceeding attention.

Fournier gangrene: role of imaging

Fournier gangrene is a rapidly progressing necrotizing fasciitis involving the perineal, perianal, or genital regions and constitutes a true surgical emergency with a potentially high mortality rate. Although the diagnosis of Fournier gangrene is often made clinically, emergency computed tomography (CT) can lead to early diagnosis with accurate assessment of disease extent. CT not only helps evaluate the perineal structures that can become involved by Fournier gangrene, but also helps assess the retroperitoneum, to which the disease can spread. Findings at CT include asymmetric fascial thickening, subcutaneous emphysema, fluid collections, and abscess formation. Subcutaneous emphysema is the hallmark of Fournier gangrene but is not seen in all cases. Compared with radiography and ultrasonography, CT provides a higher specificity for the diagnosis of Fournier gangrene and superior evaluation of disease extent; however, diagnosis and evaluation can also be performed with these other modalities. The administration of broad-spectrum antibiotics and aggressive surgical débridement of the nonviable tissue are both essential for successful treatment. An awareness of the CT features of Fournier gangrene is imperative for prompt diagnosis and effective treatment planning.

Fournier's gangrene: exists and it is still lethal

BACKGROUND

Fournier's gangrene is an aggressive form of necrotizing fascitis of the perineal, perianal or genital regions, caused by a polymicrobial infection that includes virulent organisms.

PATIENTS AND METHODS

Eleven cases of Fournier's gangrene were treated in our department during the last 20 years. Portals of entry were ischiorectal abscess, perirectal abscesses, scrotal abscess and trauma in the perianal area. The documents were analyzed according to clinical and epidemiologic patterns.

RESULTS

We dispensed systemic chemotherapy with broad-spectrum antibiotics, and performed surgical debridement for all patients. In addition, one patient was treated by local use of 100% oxygen, with excellent results in wound healing. All patients made a full recovery, except one who died of sepsis.

CONCLUSION

These cases are presented with some notes underlying the reasons for the persisting incidence and mortality of this disease.

Factors affecting mortality of Fournier's gangrene: review of 70 patients

BACKGROUND

Fournier's disease is a potentially fatal, acute, gangrenous infection of the scrotum, penis or perineum associated with a synergistic bacterial infection of the subcutaneous fat and superficial fascia.

METHODS

The clinical records of 70 patients treated for Fournier's gangrene were evaluated retrospectively to determine prognostic indices and to stress Fournier's Severity Index (FSI), influencing outcome.

RESULTS

The mortality rate in this study was 22.8%. Length of the hospitalization time and FSI were detected as effective factors on mortality of Fournier's gangrene (P < 0.05) by Binary Logistic Regression analysis and the area under the receiver operating characteristic curve of these variables was also found to be significant (P < 0.001). The average FSI was determined as 4.66 +/- 2.31 in survivors and 11.56 +/- 2.68 in non-survivors and 5.11 +/- 2.83 in patients with primary genito-urinary infection but 7.56 +/- 4.35 in primary anorectal infection. The FSI was also found predictive of hospitalization time and number of debridements among survivors.

CONCLUSION

Fournier's Severity Index is a simplified way of comparing patients with this disease and may also have some significance in predicting outcome. The FSI is a more significant and predictive tool that should be popularized to predict the prognosis in Fournier's gangrene.

Intraurethral honey application for urethral injury: an experimental study

OBJECTIVES

To evaluate the effect of honey applied intraurethrally after urethral injury on histopathological healing.

MATERIALS AND METHODS

A total of Wistar male rats were used. The rats were divided into four groups: control (Group 1), sham (Group 2), 1 week honey applied group (Group 3) and 3 weeks honey applied group (Group 4). The urethral damage was caused with a 29 G needle. In sham group, only intraurethral saline solution was given, and 10% of honey was applied to rats in Groups 3 and 4 intraurethrally. After killing, penile tissues were investigated under a light microscopy.

RESULTS

The irregularities of urethral epithelium and connective tissue were observed in Group 1. Also narrowing of lumen was present in control group rats except one rat in which no inflammation and total healing were observed. Hyperemia-bleeding was found in whole rats. In Group 2, there were irregularities in urethral epithelium and connective tissue. Total healing was observed in one rat. In Group 3, while regularity in urethral epithelium was present in six rats, inflammation and fibrosis was absent in rats. In Group 4, inflammation and fibrous tissue accumulation were not observed in rats.

CONCLUSIONS

Intraurethral honey, applied after urethral injury, prevents inflammation, accelerates urethral healing and provides perfect healing.

Fournier's gangrene: risk factors and strategies for management

OBJECTIVE

The prognosis of Fournier's gangrene (FG) depends on early diagnosis and management. In this study, our objective was to identify the distinct features of FG that may influence the clinical outcome.

METHODS

A retrospective chart review was performed in patients with a diagnosis of FG between January 1999 and December 2003. Etiological and predisposing factors, causative microbiological organisms, and clinical outcome were investigated.

RESULTS

Twenty-five men (71%) and 10 women (29%) were included in the study. Mean age was 59.7 +/- 10.7 (range: 43-88) years. As a predisposing factor, diabetes mellitus (DM) was found to be in 46% of patients. All patients were treated by immediate debridement and wide-spectrum antibiotics. More than one bacterium was found in 75% of the patients' tissue cultures, and most frequently E. coli (43%) was identified. Although there were no etiological factors in 25 patients (71%), various etiological factors were found in 10 patients (29%). Multiple debridements were performed in the majority of the cases. The overall mortality rate was 40%. The mortality rates were found to be relatively higher in patients with diabetes mellitus (DM; 50%), with delayed admission to the hospital (45%), and in patients presenting with sepsis at the first admission to the hospital (78%) compared with others. In the logistic regression model, the presence of sepsis was as the only significant independent risk factor for mortality in FG.

CONCLUSIONS

Despite the use of contemporary effective antibiotic treatment, aggressive debridements, and state-of-the-art intensive care conditions, FG still has high mortality and morbidity rates. In our series mortality rates were found to be higher in patients with delayed admission to the hospital, those with DM, and those who initially presented with sepsis.

Fournier's gangrene: report of thirty-three cases and a review of the literature

BACKGROUND

Fournier's gangrene (FG) is an extensive fulminant infection of the genitals, perineum or the abdominal wall. The aim of this study is to share our experience with the management of this difficult infectious disease.

METHODS

Thirty-three male patients were admitted to our clinic with the diagnosis of FG between February 1988 and December 2003. The patient's age, etiology and predisposing factors, microbiological findings, duration of hospital stay, treatment, and outcome were analyzed. The patients were divided into two groups. The first 21 patients (Group I) were treated with broad-spectrum triple antimicrobial therapy, broad debridement, exhaustive cleaning, and then they underwent split-thickness skin grafts or delayed closure as needed. The other 12 patients (Group II) were treated with unprocessed honey (20-50 mL daily) and broad-spectrum triple antimicrobial therapy without debridement. Their wounds were cleaned with saline and then dressed with topical unprocessed honey. The wounds were inspected daily and the honey was reapplied after cleaning with normal saline. Then, the patients' scrotum and penis were covered with their own new scrotal skin. The mean age of the patients was 53.9 +/- 9.56 years (range = 23-71).

RESULTS

The source of the gangrene was urinary in 23 patients, cutaneous in seven patients, and perirectal in three patients. The predisposing factors included diabetes mellitus for 11 patients, alcoholism for 10 patients, malnutrition for nine patients, and medical immunosuppression (chemotherapy, steroids, malignancy) for three patients. The mean duration of hospital stay was 41 +/- 10.459 (range = 14-54) days. Two patients in Group I died from severe sepsis. The clinical and cosmetic results were better in Group II than Group I.

CONCLUSION

Necrotizing fasciitis of the perineum and genitalia is a severe condition with a high morbidity and mortality. Traditionally, good management is based on aggressive debridement, broad-spectrum antibiotics, and intensive supportive care but unprocessed honey might revolutionize the treatment of this dreadful disease by reducing its cost, morbidity, and mortality.

Fournier's gangrene: Three years of experience with 20 patients and validity of the Fournier's Gangrene Severity Index Score

OBJECTIVE

To evaluate effective factors in the survival of patients with Fournier's gangrene (FG) and to determine the validity of the Fournier's Gangrene Severity Index (FGSI), which was designed for determining disease severity in these patients.

METHODS

The study included 20 men with a median age of 63.5 yr treated for FG between July 2002 and June 2005. The data were evaluated about medical history, symptoms, physical examination findings, vital signs, admission and final laboratory tests, timing and extent of surgical debridement, and antibiotic treatment used. All the patients had radical surgical debridement. The FGSI, which was developed to assign a numerical score that describes the acuity of the disease, was used in our study. This index presents patients' vital signs (temperature, heart and respiratory rates) and metabolic parameters (sodium, potassium, creatinine, and bicarbonate levels, hematocrit, white blood cell count) and computes a score relating to the severity of the disease at that time. The data were assessed according to whether the patient survived or died.

RESULTS

Of the evaluated 20 patients, 6 died (30%) and 14 survived (70%). The difference in age between survivors (median age, 60.0 yr) and those who died (median age, 64.5 yr) was not significant (p = 0.321). The median extent of the body surface area involved in the necrotizing process in patients who survived and did not survive was 2.3% and 4.8%, respectively (p = 0.001). Except for the albumin and alkaline phosphatase levels, no significant differences were found between survivors and who those died in the other admission laboratory parameters. The median admission FGSI scores for survivors and nonsurvivors were 2.0+/-2.2 and 4.0+/-3.7, respectively (p = 0.331).

CONCLUSIONS

The FGSI score did not predict the disease severity and the patient's survival. Metabolic parameters, predisposing factors, and extent of the disease seemed to be important risk factors for predicting FG severity and whether or not a patient survived.
