[New aspects in Fournier's gangrene - a rapid review]. / Neue Aspekte zur Fournierschen Gangrän ­ Ein Rapid Review.

Fournier's gangrene (FG) is a sporadic, life-threatening, necrotising infection affecting the perineum, perineal region and genitals. Published literature provides hints that the outcome of this disease has failed to improve in recent years. We have therefore performed a rapid evidence synthesis by searching the database MEDLINE. The literature from 2020 was studied to identify new aspects to improve the care of FG patients and plan further therapeutic research. 18 publications were chosen for this review, 15 of these were original research and three systematic reviews. 12 were retrospective case series, 2 epidemiological studies, with one prospective clinical study, one systematic review and 2 systematic reviews, together with a meta-analysis. Most of the authors of the studies concluded that FG is still a severe disease with unacceptable mortality rates, so that there is urgent need for therapy improvement. New risk factors for higher mortality in FG have been identified in these studies, namely dyslipoproteinemia, diabetes mellitus, heart disease, as well as both acute and chronic kidney failure. Furthermore, 4 of the included studies investigated the association of SGLT2- and DDP4-inhibitors, which are drugs used in diabetes mellitus, and the incidence of FG. No studies reported a significant association between these drugs and FG, especially not a meta-analysis with 84 included studies. New promising concepts for wound conditioning are hyperbaric oxygenation (HBO), vacuum-assisted wound closure (VAC) and Maggot therapy (blowfly larvae). In summary, FG is still a severe disease, the prognosis has not improved in recent years and so there is an urgent need for improved therapy. This could only be achieved with further research in FG. In our opinion and due to the rarity of FG, this would be possible with a national registry study. For example, it might be possible to calculate risk stratification from this registry to identify patients who would benefit from treatment in a centre or with special wound conditioning.

Fournier's gangrene - challenge for surgeon.

INTRODUCTION: Fournier gangrene (FG) is life - threatening condition, defined as the necrotizing fascitis of perineum and can spread to the adjacent areas. It is rare disease and infection is caused by mixed bacterial flora, seldom by fungal infection. Risk factors are: male sex, diabetes, hypertension, malignant neoplasms, alcoholism, immunospression. MATERIAL AND METHODS: The analysis of four group patients treateted for Fournier gangrene was made about diagnostic and therapeutic process, assessment of prognosis based on Fournier's Gangrene Severity Index). RESULTS: All patients were males. Average age at the moment of diagnosis was 60 years. All of them had comorbidities resulting with the higher risk of susceptibility to FG. Morbitity was 50%, despite of all of patients had less than 9 points in FGSI. DISCUSSION: The FG, despite of better diagnostic tools and technological progres remaines the significant clinical issue because of the mortality - 80%. "The golden standard" is surgical excision of necrotic tissues, antibiotics support, equation of fluid, electrolytes and base - acid balance, level of glycemia is very important. The treating results were assessed on the base of FGSI. The significance has the moment of performing the surgical intervention - it is proven, that should be carried out during 24 hours. The hyperbaric oxygen therapy is controversial. Seem to be appropriate if the infection is caused by anaerobic bacteria. CONCLUSIONS: Fournier syndrome is significant clinical issue. Its treatment requires early surgical approach with exicision of necrotic tissues, antibiotics support and treatment of hyperbaric oxygen in some cases.

Significance of Hyperbaric Oxygenation in the Treatment of Fournier's Gangrene: A Comparative Study.

INTRODUCTION: Hyperbaric oxygenation (HBO), in addition to anti-infective and surgical therapy, seems to be a key treatment point for Fournier's gangrene. The aim of this study was to investigate the influence of HBO therapy on the outcome and prognosis of Fournier's gangrene. PATIENTS AND METHODS: In the present multicenter, retrospective observational study, we evaluated the data of approximately 62 patients diagnosed with Fournier's gangrene between 2007 and 2017. For comparison, 2 groups were distinguished: patients without HBO therapy (group A, n = 45) and patients with HBO therapy (group B, n = 17). The analysis included sex, age, comorbidities, clinical symptoms, laboratory and microbiological data, debridement frequency, wound dressing, antibiotic use, outcome and prognosis. The statistical analysis was performed with GraphPad Prism 7® (GraphPad Software, Inc., La Jolla, USA). RESULTS: Demographic data showed no significant differences. The laboratory parameters C-reactive protein and urea were significantly higher in group B (group B: 301.7 vs. 140.6 mg/dL; group A: 124.8 vs. 54.7 mg/dL). Sepsis criteria were fulfilled in 77.8 and 100% of the patients in groups A and B respectively. Treatment in the intensive care unit (ICU) was therefore indicated in 69% of the patients in group A and 100% of the patients in group B. The mean ICU stay was 9 and 32 days for patients in groups A and B respectively. The wound debridement frequency and hospitalization stay were significantly greater in group B (13 vs. 5 debridement and 40 vs. 22 days). Initial antibiosis was test validated in 80% of the patients in group A and 76.5% of the patients in group B. Mortality was 0% in group B and 4.4% in the group A. CONCLUSION: The positive influence of HBO on the treatment of Fournier's gangrene can be estimated only from the available data. Despite poorer baseline findings with comparable risk factors, mortality was 0% in the HBO group. The analysis of a larger patient cohort is desirable to increase the significance of the results.

A conservative approach to perineal Fournier's gangrene.

Fournier's gangrene (FG) is a disease involving necrosis of perineum and external genitalia; in 95% of cases it is possible to diagnose the Fournier's gangrene just by physical examination. The clinical presentation of FG varies from an initial localized infection to large areas with necrotizing infection. The disease typically affect elderly men (6°-7° decade) with important systemic comorbidities; women are less frequently affected. Despite improvements in diagnosis and management, the mortality rate nowadays is between 20% and 43%. The severity and mortality of the disease is dependent upon the general condition of the patient at presentation and upon the rate of spread of the infection. Treatment involves a multidisciplinary approach: intensive systematic management, broad-spectrum antibiotic therapy, early surgical debridement (wide abscission of necrotic tissues and surgical drainage of peritoneum, scrotum, penis, and inguinal areas), hyperbaric oxygen therapy; surgery can eventually be repeated if necessary; reconstructive surgery has an important role in the final treatment of the disease. The technical difficulties frequently encountered and the inability to make a complete removal of the necrotizing tissues at the time of surgery in some cases has led to the application of combined techniques, in view of the enhancement effect of specific advanced medications, targeted antibiotic therapy and hyperbaric medicine. We have considered 6 patients affected by Fournier's gangrene treated at our institution; all the patients received treatment with the help of plastic surgeons of the same institution. After debridement, all the patients were treated with advanced specific dressings consisting of plates and strips made of calcium alginate, hydrogels and polyurethane and twodimensional cavity foams. Reconstructive surgery was necessary in one case. Hyperbaric oxygen therapy (HBO) has been performed in all cases. The multidisciplinary approach, the combined use of HBO therapy and the adoption of advanced specific dressings, have made possible the complete healing of the lesions in a shorter period, avoiding further surgery in 5 out of 6 patients.

Hyperbaric Oxygen Therapy as an Adjuvant Therapy for Comprehensive Treatment of Fournier's Gangrene.

OBJECTIVES: To compare simple conventional treatment with the addition of hyperbaric oxygen therapy (HBOT) to conventional therapies in the treatment of Fournier's gangrene (FG). METHODS: A retrospective study of clinical data was performed by reviewing 28 cases of FG from January 2004 to December 2013 at Xiangya Hospital, Central South University. Among them, 12 patients were treated with the conventional therapy (non-HBOT group) and the other 16 cases were combined with hyperbaric oxygen therapy besides conventional therapy (HBOT group). All patients were followed up for 2 months to assess the therapeutic effect. The analyzed data included age, Fournier gangrene severity index (FGSI) score, number of surgical debridement, indwelling drainage tube time, length of stay (LOS), effective time, and curative time. RESULTS: The mortality rate was lower in the HBOT group at 12.5% (2/16) compared to the non-HBOT group, which was 33.3% (4/12). The difference in the number of surgical debridement, indwelling drainage tube time, and curative time between were significantly lower in the HBOT group compared to the non-HBOT group. CONCLUSIONS: Our preliminary research suggests that the effect of combining hyperbaric oxygen therapy with conventional therapy offers considerable advantage in the management of Fournier's gangrene. Multicenter studies with a larger sample size are required to confirm these observations.

Use of adjunctive treatments in improving patient outcome in Fournier's gangrene.

Fournier's gangrene is a polymicrobial necrotising soft tissue infection (NSTI) affecting the perineum and scrotum. It is rapidly progressive and destructive, and is associated with high morbidity and mortality. Management protocol includes prompt diagnosis, early institution of antibiotic therapy and adequate wound debridement, usually requiring multiple operations. The resultant defect can be left to heal by secondary intention, or surgical coverage can be undertaken. We report Fournier's gangrene in a 60-year-old diabetic man and his successful treatment with skin grafting, which utilised a multidisciplinary approach and adjuncts, including negative-pressure wound therapy and hyperbaric oxygen therapy. We also review the literature related to these adjuncts and discuss their usefulness in the management of NSTIs.

Terapia de oxígeno hiperbárico complementaria al desbridamiento en el control de la gangrena de Fournier: utilidad de la puntuación de un índice de severidad en la predicción de la gravedad de la enfermedad y la supervivencia del paciente / 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

Introducción: La terapia de oxígeno hiperbárico (TOHB) concomitante con la cirugía ha demostrado una mejora en la reducción de la mortalidad por gangrena de Fournier (GF) en comparación con la aplicación exclusiva de desbridamiento quirúrgico. La mayoría de los datos provienen de centros con un número relativamente reducido de pacientes, y en los que se emplea solamente un procedimiento quirúrgico. El objetivo planteado consistía en evaluar la eficiencia del desbridamiento agresivo con TOHB complementaria, así como evaluar el valor predictivo del índice de puntuación de gravedad de la gangrena de Fournier (IGGF). Material y métodos: 70 gangrenas de Fournier (GF) tratadas con desbridamiento quirúrgico y TOHB. Los datos evaluados fueron los resultados de las exploraciones físicas, los análisis de laboratorio tanto en el momento del ingreso como los finales, la extensión del desbridamiento quirúrgico y el antibiótico utilizado. Los pacientes recibieron TOHB complementaria. Se desarrolló un IGGF con el fin de adjudicar una puntuación que describiese la gravedad de la enfermedad. Este índice tiene en cuenta las constantes vitales de los pacientes, los parámetros metabólicos (niveles de sodio, potasio, creatinina y bicarbonato, así como recuento de linfocitos) y calcula una puntuación relativa a la gravedad de la enfermedad en ese momento. Se evaluaron los datos en función de la supervivencia o no del paciente. Todos los pacientes fueron sometidos a desbridamiento quirúrgico, realizándose el desbridamiento de la herida de forma periódica en el periodo postoperatorio. Resultados: De un total de 70 pacientes fallecieron 8 (el 11,4%) y sobrevivieron 62 (el 88,5%). La diferencia de edad entre los supervivientes (edad media 50,0 años) y no supervivientes (edad media 54,5 años) no fue significativa (p = 0,321). La extensión media del área del cuerpo afectada por el proceso de necrosis en los pacientes que sobrevivieron y en los que no sobrevivieron era del 2,4 y del 4,9%, respectivamente (p = 0,001). Excepto en lo referente a la albúmina, no se encontraron diferencias significativas entre supervivientes y no supervivientes. Las puntuaciones medias en el IGGF en el momento del ingreso de los supervivientes y de los no supervivientes fueron de 2,1±2,0 y de 4,2±3,8, (p = 0,331). Conclusión: La puntuación del IGGF no resultó ser un factor de predicción de la gravedad, de la enfermedad ni de la supervivencia del paciente. Sin embargo, tanto las alteraciones metabólicas como la extensión de la enfermedad aparecieron como factores significativos de riesgo en cuanto a predicción de la gravedad de la GF y la supervivencia del paciente (AU)

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 toa ssign 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 non survivors. 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 (AU)

Complex wounds and their management.

Complex wounds present a challenge to both the surgeon and patient in operative management, long-term care, cosmetic outcome, and effects on lifestyle, self-image, and general health. Each patient with complex wounds usually manifests multiple risk factors for their development. This article focuses on complex wounds involved with traumatic and orthopedic blunt or penetrating injuries, particularly in the extremities, as well as massive soft tissue infections including necrotizing fasciitis, gas gangrene, and Fournier gangrene. The principles of management of complex wounds involve assessing the patient's clinical status and the wound itself, appropriate timing of intervention, providing antibiotic therapy when necessary, and planning and executing surgical therapy, including the establishment of a clean wound bed and closure/reconstructive strategies.

Gangrena de Fournier / Fournier's gangrene

Se presenta el caso de un paciente con gangrena de Fournier o fascitis necrosante. Después de su ingreso en la Unidad de Cuidados Intensivos se le realizó tratamiento quirúrgico precoz (incisión y drenaje amplio de toda la zona afectada así como desbridamiento de la zona de necrosis); se tomó muestra de pus para estudio microbiológico y se comenzó tratamiento antibiótico de inmediato (ceftriaxona, amikacina y metronidazol). Se identificaron como agentes causantes del proceso Pseudomonas aeruginosa y Escherichia coli (sensibles a la ceftriaxona y la amikacina). Como tratamiento coadyuvante, se aplicaron 10 sesiones de cámara hiperbárica y 12 dosis de factor de crecimiento humano recombinante liofilizado, que se infiltraron en el interior de la zona quirúrgica para contribuir al cierre por tercera intención(AU)

This is the case of a patient presenting with Fournier gangrene of necrotizing fasciitis. After admission in Intensive Care Unit (ICU) he undergoes an early surgical treatment (incision and wide drainage of the whole involved zone as well as debridement of necrosis zone); a pus sample was took for microbiologic study and a immediate antibiotic treatment was started (Ceftriaxone, Amikacin and Metronidazole). Pseudomonas aeruginosa and Escherichia coli (sensitive to Ceftriaxone and Amikacin) were identified as the causative agents of process. As adjuvant treatment ten sessions of hyperbaric chamber were applied and twelve dose of lyophilized recombinant human growth factor with infiltration into the surgical zone for the third intention closure(AU)

Fournier's gangrene.

Fournier gangrene is a rare, but potentially devastating infection. A case is presented and the treatment principles are discussed.

[Fournier's gangrene. Current perspectives]. / Gangrena de Fournier. Perspectivas actuales.

The Fournier Gangrene (FG) is a synergistic, polymicrobial, necrotizing fasciitis with infectious origin that produces gangrene of the perineal, genital or perianal skin. The number bigger than cases happens between 20 at 50 years, the males are affected more than the females in proportion 10:1 and the mortality rate is high yet. The clinical manage of the GF must be fast and opportune with intravenous application of fluids, electrolytes and systemic broad-spectrum antibiotic therapy; and avoid the hemodynamic stabilization of the patient before the surgery. The precocious surgery with debridement of the necrotizing tissues constitutes the main objective of the treatment.

Death of an Arabian Jew.

A 69-year-old Judean man presents with chronic low-grade fever, pedal edema, and abdominal pain. His condition deteriorates over several weeks with the appearance of shortness and foulness of breath, pruritus, convulsions of every limb, and gangrene of the genitalia. Just before he dies, he orders dozens of the leading men of his kingdom imprisoned and instructs his sister to kill them all after he is gone. Who is he and what is the likely cause of his death?

[Life-threatening cellulitis, or Fournier's gangrene of the perineum]. / Les cellulites graves, ou gangrène de Fournier du périnée.

The global mortality for Fournier's gangrene is one in five. In half the cases, the infection is polymicrobial with either anaerobes or gram negative bacilli. Factors which worsen prognosis include renal insufficiency, streptococcal infection, or need for hospital admission. Diagnosis must be prompt and treatment multidisciplinary involving the surgeon, intensivist, and infectious disease specialist; early and adequate surgical debridement must be accompanied by well-chosen antibiotics and hyperbaric oxygen therapy. Post-debridement therapy requires a long period of dressing changes and skin grafting to achieve final wound closure. This is an aggressive disease with a high mortality, but the depth and extent of invasive infection does not determine prognosis; the first priority is prompt and wide surgical excision/debridement of infected tissues to pre-empt the development of systemic sepsis; this should not be deferred while arranging transfer to a facility with a hyperbaric chamber.

[Perineo-scrotal gangrene: apropos of 31 cases]. / La gangrène périnéo-scrotale: à propos de 31 cas.

Fournier's gangrene is a fascitis of the perineum and of the external genitalia. It is a serious infection with rapid evolution and a severe prognosis. It is also unpredictable towards the necrosis. It concerns a series of 31 cases of the perineal scrotal gangrene supervised in the department of surgical visceral emergency of the Ibn Rochd University hospital of Casablanca between 1992 and 2000. In this investigation, the male predominance is important and the mean age is 49 years. The diagnostic delay is 12 days. The symptomatology was dominated by edema and erythema signs, fever and pain. The skin necrosis was seated in the perineum and the scrotum. A septic shock was noticed in six patients and a condition of deep coma in two other patients. Etiology of gangrene was of coloproctologic origin in 15 cases and of urogenital origin in five patients. The bacteriological parietal swabs was positive in 11 cases. The therapeutic take-in-charge consisted of urgent measures of reanimation for six patients. The likely wide spectrum antibiotic therapy consisting of a triple association (beta lactam antibiotic, nitrite-imidazole compound and aminoglycoside) with a secondary adaptation that was recommended for all patients. All the patient underwent surgical debridement of the necrotic tissue with incisions and drainage of the involved areas of the of all the operated-on patients, 26 had colostomy, five among them had both colostomy and cystostomy. The overall evolution was favorable except in eight cases of death. In all, the authors insist on the positive diagnosis as well as the early take-in-charge of the disease to avoid complications of local or general order and recommended the preventive treatment with the precocious treatment of the causing infection.

Hyperbaric oxygen therapy in acute necrotizing infections with a special reference to the effects on tissue gas tensions.

Clostridial gas gangrene and perineal necrotizing fasciitis or Fournier's gangrene are rare but serious infections with an acute onset, rapid progression, systemic toxemia and a high mortality rate. The aim of this study was to investigate the efficacy of surgery, antibiotic treatment, surgical intensive care and in particular the role of hyperbaric oxygen (HBO) in the management of these infections. An experimental rat model was used to investigate the possibilities for measuring tissue oxygen and carbon dioxide tensions during hyperbaric oxygen treatment. In addition to this preliminary experimental study, Silastic tube tonometer and capillary sampling techniques were tested to measure the effect of hyperbaric oxygen treatment on subcutaneous oxygen and carbon dioxide tensions in patients with necrotizing fasciitis and healthy controls. Between January 1971 and April 1997, 53 patients with Clostridial gas gangrene were treated in the Department of Surgery, University of Turku. The patients underwent surgical debridement, broad spectrum antibiotic therapy and a series of hyperbaric oxygen treatments at 2.5 atmospheres absolute pressure (ATA). Twelve patients died (22.6%). Hyperbaric oxygen therapy in gas gangrene seems to be life-, limb- and tissue saving. Early diagnosis remains essential. Patient survival can be improved if the disease is recognized early and appropriate therapy instituted promptly. Between February 1971 and September 1996, 33 patients with perineal necrotizing fasciitis were treated in the Department of Surgery, University of Turku. The management included surgical debridement of the necrotic tissue with incisions and drainage of the involved areas, antibiotic therapy, hyperbaric oxygen treatment at 2.5 ATA pressure and surgical intensive care. Three patients died giving a mortality rate of 9.1%. The survivors received hyperbaric oxygen therapy for 2-12 times. Our results indicate that hyperbaric oxygenation is an important therapeutic adjunct in the treatment of Fournier's gangrene. Electrical equipment should not be used unsheltered in a hyperbaric chamber due to the increased risk of fire. The subcutaneous tissue gas tensions of rats were therefore measured using a subcutaneously implanted Silastic tube tonometer and a capillary sampling technique. The method was successfully adapted to hyperbaric conditions. The subcutaneous oxygen tension levels increased five fold and the carbon dioxide tension levels two fold compared to initial levels. The PO2 and PCO2 of subcutaneous tissue and arterial blood were measured directly in six patients with necrotizing fasciitis and three healthy volunteers in normobaric conditions and during hyperbaric oxygen exposure at 2.5 ATA pressure. The measurements were carried out in healthy tissue and at the same time in the vicinity of the infected area of the patients. During HBO at 2.5 ATA subcutaneous oxygen tensions increased several fold from baseline values and carbon dioxide tensions also increased, but to a lesser degree in both healthy and infected tissues. When examining the subcutaneous PO2 levels measured from patients with necrotizing fasciitis, the PO2 was regularly higher in the vicinity of the infected area than in healthy tissue. In general, HBO treatment resulted in a marked increase in tissue oxygenation in both healthy tissue and in the vicinity of infected tissue. The hyper-oxygenated tissue zone surrounding the infected area may be of significance in preventing the extension of invading microorganisms.

[Gangrene of the external genital organs. Apropos of 55 cases]. / La gangrène des organes génitaux externes. A propos de 55 cas.

Gangrène of the male external genitalia (GMEG) is characterized by necrotizing cell evolving toward necrotizing of the soft tissues of the male genitalia and possibly death. The cause may be primary infection called Fournier's gangrene (5%) or secondary infection (95%) due to general or local factors. GMEG is a real urinary emergency because of its local and general complications which lead to death in 20% of cases. Precocious and massive antibiotherapy, a surgery to unbridle and possibly reanimation, oxygenotherapy, urinary diversion or colostomy, are required. We have treated 55 men with this affection from january 1988 to may 1996. Mean age was 58 years (range 20 to 85). The prodromial period was about 12 days. Toxi-infectious shock was noted in 8 patients (14%). Six patients (10%) developed renal acute insufficiency. Lesions were localized to the male external genitalia in 24 cases and stretched to the inguinalis, to the abdomen or to the thorax in 34 patients. The cause was a stricture of urethra in 23 cases (41%) diabetes in 18 cases (32%), anal abscess in 7 cases (13%). No etiology was found in 6 cases (10%). Emergency treatment involved three antibiotics, surgery to unbridle necrotizing tissue in all patients, reanimation in 20 patients (35%), oxygenotherapy in 4 patients (7%), colostomy in 2 cases and urinary drainage in 23 patients (42%). Free skins grafts were necessary in 6 patients (10%), 5 patients (9%) died due to septic shock. On the basis of these observations and a review of the literature, we analyzed the ethiopathogenic, bacteriological and therapeutic aspects of this affection marked by high mortality in spite of therapeutic progress.
