Risk Factors for Mortality Among Patients With Fournier Gangrene: A Systematic Review.

Background: Fournier gangrene (FG) is a form of necrotizing fasciitis involving the perineal, peri-anal, and genital structures, and has exceptionally high mortality rates. To help in early detection of high-risk patients, we aimed to systematically review factors associated with mortality from FG. Patients and Methods: Searches were conducted in PubMed, Embase and Scopus. In our review, a minimum of five patients were required and this was to exclude studies with exceedingly small sample sizes, such as case reports and small case series, with minimal relevance in comparison to larger scale studies. Patient characteristics, causative microbes, anatomic areas of infection, presence of comorbidities, severity scores, causes of FG, and complications were extracted and compared to identify factors related to mortality. Results: A total of 57 studies were included in the review. Across 3,646 study participants, the mortality rate of FG was 20.41%. The mean age of non-survivors was 61.27 years. There were more total male deaths, however, the mortality rate was higher in females. Diabetes mellitus was the most common comorbidity in those who died, but the highest mortality rate was seen in HIV patients (54.17%). Mortality rates did not differ widely among antibiotic agents. Regarding causative organisms, fungal infections had the highest rates of mortality (68.18%) and the most common microbe leading to death was Escherichia coli. Conclusions: Female gender, comorbidities, anatomic distribution, development of sepsis, and fungal infection all increased risk for mortality. Early identification of risk factors, and provision of appropriate treatment are crucial in reducing mortality rates of high-risk patients with FG.

Fournier's gangrene in a female: A case report.

Fournier's gangrene is characterized by an acute necrotic infection. The infection can occur in all parts of the body including the scrotum, penis, or perineum, and is a rare condition that is primarily reported in men and seldom in women. Existing literature suggests that it might be underreported, possibly leading to overlooked cases. Risk factors include diabetes, chronic illness, and trauma. This case involves a 52-year-old female with a 10-year medical history of diabetes mellitus, multiple healed skin lesions all over the body, and dermatitis. The presentation was a perianal swelling, which progressed into an extensive necrotizing soft tissue infection of the perineum, making a diagnosis of Fournier's gangrene. She underwent wide local debridement and was managed with antibiotics in a timely manner. The patient's clinical course and subsequent follow-up were uneventful. Uncontrolled diabetes and dermatitis significantly increase the risk of Fournier's gangrene; therefore, it should be suspected in women with such comorbid conditions. This case highlights the need for increased awareness and vigilance regarding this condition among women.

A rare case of Fournier's gangrene developing from colon perforation in an infant: A case report.

Fournier's gangrene, a rare and life-threatening soft tissue infection affecting the genitalia and perineum, results from various microorganisms. This rapidly progressing necrotizing fasciitis yields higher mortality and morbidity rates. We report a case of a 1-month-old male infant with Fournier's gangrene due to perforation transverse colon complicated with septic shock and pneumonia also accompanied by patent processus vaginalis. Radiological findings of pneumonia and pneumoperitoneum were exhibited. Early diagnosis and management are demanded to mitigate life-threatening and improve the prognosis. The patient underwent incision drainage, peritoneal lavage, exploratory laparotomy, colostomy, necrotomy debridement, and patent processus vaginalis ligation after hemodynamic status stabilization.

Role of diverting colostomy and reconstruction in managing Fournier's gangrene-a narrative review.

OBJECTIVE: To examine the role of bowel diversion and reconstructive surgeries in managing Fournier's gangrene (FG) to facilitate multidisciplinary collaboration between urologists, colorectal and plastic surgery teams. METHODS: A review of the literature was conducted using the databases Medline, Embase, PubMed in June 2023. The review included studies that evaluated the outcomes of FG following reconstructive surgeries or diverting colostomies. RESULTS: The existing evidence suggests that bowel diversion and colostomy formation could reduce the need for further debridement, shorten the time to wound healing, and facilitate skin graft or flap uptake in patients with FG. Additionally, the psychological impact of a stoma was shown not to be a major concern for patients. However, stoma carries a risk of perioperative complications and therefore may prolong the length of hospital stay. In reviewing the evidence for reconstruction in FG, large and deep defects seem to benefit from skin grafts or flaps. Noticeably, burial of testicles in thigh pockets has grown out of favour due to concerns regarding the thermoregulation of the testicles and the psychological impact on patients. CONCLUSION: The use of bowel diversion and reconstructive surgeries in managing FG is case dependent. Therefore, it is important to have close discussions with colorectal and plastic surgery teams when managing FG.

Fournier's gangrene: a review of predictive scoring systems and practical guide for patient management.

This article aims to provide a practical guide for patient management and an overview of the predictive scorings for Fournier's gangrene (FG) that are available to aid clinicians. A literature was performed reviewing currently used scoring systems for FG and presenting a practical guide for its management based on the available evidence. There are four specific scoring systems available for the assessment of FG although few other non-specific and generic tools also exist. These specific tools include Laboratory Risk Indicator for Necrotizing Fasciitis, Fournier's Gangrene Severity Index, Uludag Fournier's Gangrene Severity Index, and Simplified Fournier's Gangrene Severity Index and help calculate expected mortality. Our proposed algorithm covers primary assessment, resuscitative interventions, initial investigations, urgent care, post-operative care, and long-term follow-up. The management of the FG patient can be divided into initial resuscitation, surgical debridement, ongoing ward management with antibiotic therapy, wound reconstruction, and long-term follow-up. Each facet of care is vital and requires multidisciplinary team expertise for optimal outcomes. Whilst mortality continues to improve, it remains significant, reflecting the severe and life-threatening nature of FG. More research is certainly needed into how this care is individualised, and to ensure that long-term outcomes in FG include quality of life measures after discharge.

Nursing care plan for a patient with Fournier's gangrene: Clinical case.

INTRODUCTION: Fournier's gangrene, a relatively rare form of necrotizing fasciitis, is a rapidly progressive disease affecting the deep and superficial tissues of the perineal, anal, scrotal, and genital regions. Despite the significant evolution in medical knowledge, there is still scarce evidence regarding the nursing care plan in patients affected by this pathology, which hinders its correct management. For this reason, we present the following clinical case of a 53-year-old male patient with Fournier's gangrene who was admitted to the emergency department for 3 days of pain in the perineal area and fever. OBJECTIVE: The objective was to establish an individualized care plan for the patient detailing the diagnoses, expected outcomes and interventions through nursing taxonomies. CASE DEVELOPMENT: A systematic assessment was performed using Marjory Gordon's model of functional health patterns as a reference. After drawing inferences, three collaborative problems and two nursing diagnoses were established with their outcome criteria and interventions. Once the plan was executed, the results obtained highlighted that the interventions were consistent in achieving the objectives set out in the problems present in the case patient. CONCLUSIONS: The development of an individualized plan made it possible to detect problems, establish realistic objectives and define interventions that optimized nursing care in this patient with Fournier's gangrene.

Post catheterization Fournier's gangrene involving the entire anterior urethra: case report.

INTRODUCTION AND IMPORTANCE: Fournier's gangrene is necrotizing fasciitis involving the penis, scrotum, or perineal region. This is to report necrosis of the entire anterior urethra by necrotizing infection even though the involvement of the urethra by Fournier's is a very rare presentation. A high index of suspicion is important for early intervention. The main Mode of treatment for Fournier's gangrene is debridement. CASE PRESENTATION: This is a case report for a 58-year-old male patient who presented with penile and scrotal swelling after he was catheterized with NG tube for acute urinary retention. The physical finding shows swollen scrotum with ulcerated necrotic glans penis anteriorly. Laboratory result shows leukocytosis and urine analysis is positive for urinary tract infection and ultrasound shows bladder diverticula with normal prostate volume. He underwent debridement up to the level of membranous urethra and suprapubic catheterization was done. He was treated with antibiotics and wound care and finally, the wound closed. Post-operative cystourethrography was done 9 months later and we offered staged urethroplasty but he decided for permanent SPC. DISCUSSION: Fournier's gangrene is a fatal rapidly spreading infection that occurs in the perineal area. Involvement of urethra by necrotizing infection following catheterization is very rare presentation and diagnosis is mostly clinical. Once it is diagnosed the management is surgical debridement. CONCLUSION: Fournier's gangrene with urethral involvement is a very rare presentation and a high index of suspicion is important for early diagnosis and management. Following the standard procedural steps of catheterization is important to avoid this complication.

Fournier's gangrene revealing an acute arterial occlusion: A case report.

INTRODUCTION AND IMPORTANCE: Fournier gangrene (FG) is a rare form of necrotizing fasciitis that affects both the deep and superficial layers of the perineal genital region. When left untreated, Fournier gangrene can rapidly advance, leading to substantial morbidity and mortality. Herein, we present a case of Fournier's gangrene, which revealed acute arterial occlusion. To the best of our knowledge, few cases of Fournier's gangrene secondary to arterial occlusion have been reported. CASE PRESENTATION: We report the case of a 37-year-old man with no known medical history who presented with fever and painful swelling of the scrotum. Physical examination revealed a large black spot on the scrotum surrounded by erythema, suggestive of Fournier's gangrene. We performed an extended debridement of the scrotal area. Three days later, the patient complained of severe pain in the left foot accompanied by numbness. Lower limb computed tomographic angiography (CTA) revealed multiple arterial occlusions. Thrombectomy and anticoagulation therapy were crucial in managing the vascular thrombosis and preventing the further extension of the gangrene. CLINICAL DISCUSSION: This case underscores the importance of recognizing diverse etiologies of Fournier's gangrene, including vascular involvement, and emphasizes the need for a multidisciplinary approach. Early identification, aggressive surgical debridement, and broad-spectrum antibiotics remain the cornerstone of management, with the added consideration of anticoagulation in cases involving vascular thrombosis. CONCLUSION: FG is a rare yet potentially life-threatening condition. Its multifaceted etiologies, including vascular factors, underscore the complexity of its presentation and challenges for timely diagnosis. The recognition of vascular involvement as a potential etiology of FG warrants further in-depth exploration.

Role of SFGSI, microbial culture and qSOFA as predictive factors in determining the survival rate in Fournier Gangrene patient.

OBJECTIVES: To examine the simplified Fournier Gangrene Severe Index Score (SFGSI) and the number of species in culture findings for predicting death in Fournier Gangrene (FG) patients in terms of their predictive power. METHODS: From January 2017 to July 2022, the medical records of individuals undergoing emergency surgery for FG were obtained. A total of 80 patients were examined for clinical data such as age, gender, laboratory parameters, etiology, isolated bacteria, and mortality rate. RESULTS: We identified a statistically significant mean difference between SFGSI (p<0.0001) and quickSOFA (qSOFA) scores (p=0.002) in determining the survival rate of FG patients. The sensitivity and specificity of the SFGSI score in predicting mortality were 90.1% and 88.3% respectively, whereas the sensitivity and specificity of the qSOFA score were 88.2% and 86.2%. E. Coli comprised 56.2% of the bacteria, followed by S. Haemolyticus, S. Aureus, P. Aeruginosa, and K. Pneumoniae. On the basis of bacterial culture results, P. Aeruginosa had the highest fatality rate (100%) followed by S. Aureus (75%), S. Haemolyticus (30%), and E. Coli (20%), in that order. CONCLUSION: The survival rate of FG patients can be predicted using the sensitivity and specificity of the SFGSI and qSOFA scores together. P. Aeruginosa-infected patients have the greatest mortality rate (100%) compared to the other groups.

Reported outcome measures in necrotising soft tissue infections: a systematic review.

Introduction: There are inconsistencies in outcome reporting for patients with necrotising soft tissue infections (NSTI). The aim of this study was to evaluate reported outcome measures in NSTI literature that could inform a core outcome set (COS) such as could be used in a study of hyperbaric oxygen in this indication. Methods: A systematic review of all NSTI literature identified from Cochrane, Ovid MEDLINE and Scopus databases as well as grey literature sources OpenGrey and the New York Academy of Medicine databases which met inclusion criteria and were published between 2010 and 2020 was performed. Studies were included if they reported on > 5 cases and presented clinical endpoints, patient related outcomes, or resource utilisation in NSTI patients. Studies did not have to include intervention. Two independent researchers then extracted reported outcome measures. Similar outcomes were grouped and classified into domains to produce a structured inventory. An attempt was made to identify trends in outcome measures over time and by study design. Results: Three hundred and seventy-five studies were identified and included a total of 311 outcome measures. Forty eight percent (150/311) of outcome measures were reported by two or more studies. The four most frequently reported outcome measures were mortality without time specified, length of hospital stay, amputation performed, and number of debridements, reported in 298 (79.5%), 260 (69.3%), 156 (41.6%) and 151 (40.3%) studies respectively. Mortality outcomes were reported in 23 different ways. Randomised controlled trials (RCTs) were more likely to report 28-day mortality or 90-day mortality. The second most frequent amputation related outcome was level of amputation, reported in 7.5% (28/375) of studies. The most commonly reported patient-centred outcome was the SF-36 which was reported in 1.6% (6/375) of all studies and in 2/10 RCTs. Conclusions: There was wide variance in outcome measures in NSTI studies, further highlighting the need for a COS.

Fournier's gangrene due to rectal cancer: A case report.

Fournier's gangrene (FG) is an extremely rare necrotizing fasciitis that is insidious, rapidly spreading and life-threatening. FGs due to rectal cancer occur rarely and there is a lack of clinical reference. In the present study, a severe FG due to rectal cancer perforation was described and the features of this rare disease were summarized with a literature review. A 57-year-old man was admitted because of rectal cancer-induced FG. The patient was misdiagnosed with extensive perianal abscess until the intraoperative biopsy confirmed that rectal cancer was the culprit. Incision, debridement and drainage were carried out to reduce infectious burdens. After that, the patient was transferred to Peking University People's Hospital for the subsequent therapy. Empirical broad-spectrum antibiotic therapy was used at the initial stage. Diversional transverse loop colostomy was performed to control infection and resume oral feeding. After four rounds of vacuum-assisted closure (VAC) therapy, radical resection and wound closure were accomplished. The scrotal defect was repaired by a skin flap. Pathological results indicated a moderately differentiated adenocarcinoma with perforation. The patient was discharged from the hospital on postoperative day 15 without any post-operative complications. No signs of recurrence were observed during a 22-month follow-up. In the setting of rectal cancer-induced FGs, the liquid resuscitation, broad-spectrum antibiotic therapy, and prompt debridement are the cornerstones of the initial management. Diversional colostomy and VAC therapy were effective in the management of severe infection and large wounds. The present case report also provided a clinical reference for the implementation of staged surgeries and the perioperative multidisciplinary management of FGs.

Crafting Contours: A Comprehensive Guide to Scrotal Reconstruction.

This review delves into reconstructive methods for scrotal defects arising from conditions like Fournier's gangrene, cancer, trauma, or hidradenitis suppurativa. The unique anatomy of the scrotum, vital for thermoregulation and spermatogenic function, necessitates reconstruction with thin and pliable tissue. When the scrotal defect area is less than half the scrotal surface area, scrotal advancement flap can be performed. However, for larger defects, some type of transplantation surgery is required. Various options are explored, including testicular transposition, tissue expanders, split-thickness skin grafts, local flaps, and free flaps, each with merits and demerits based on factors like tissue availability, defect size, and patient specifics. Also, physicians should consider how testicular transposition, despite its simplicity, often yields unsatisfactory outcomes and impairs spermatogenesis. This review underscores the individuality of aesthetic standards for scrotal reconstruction, urging surgeons to tailor techniques to patient needs, health, and defect size. Detailed preoperative counseling is crucial to inform patients about outcomes and limitations. Ongoing research focuses on advancing techniques, not only anatomically but also in enhancing post-reconstruction quality of life, emphasizing the commitment to continuous improvement in scrotal reconstruction.

Fournier's gangrene with Streptococcus Anginosus in the setting of hidrandenitis suppurativa perineal abscess: A case report.

INTRODUCTION: Fournier's gangrene is a rare but life-threatening form of necrotizing soft tissue infection involving the perineal, genital, or perianal region, commonly caused by a mix of aerobic and anaerobic organisms. Initially discovered in dental abscesses, Streptococcus anginosus have been increasingly reported in pyogenic and systemic infections with abscess formation. We present a rare case of perineal abscess that developed into Fournier's gangrene in which the causative pathogen isolated was S. anginosus. PRESENTATION OF CASE: A 58-year-old male with uncontrolled type 2 diabetes, hypertension and hidradenitis suppurativa of the groin, presented with worsening testicular pain. He was found to have a necrotizing soft tissue infection of the perineum, consistent with Fournier's gangrene. He was successfully treated with multiple surgical debridement and broad-spectrum intravenous antibiotics. He was transitioned to oral antibiotics before transferring to a tertiary care facility for reconstruction. DISCUSSION: The setting of uncontrolled diabetes and hidradenitis suppurativa may be the likely etiology for this peculiar case of Fournier's gangrene secondary to S. anginosus. Compromised tissue integrity and impaired local immune defenses from these etiologies predisposes to the development of Fournier's gangrene. Historically, these abscesses typically resolve after intravenous antibiotics and incision and drainage. However, the abscess in this case did not resolve but rather progressed to Fournier's gangrene. Perineal abscesses that grow S. anginosus should raise a high index of suspicion for worse outcomes. CONCLUSION: In conclusion, we recommend a multidisciplinary approach and rapid diagnosis for the management of S. anginosus in the setting of a perineal abscess, with early aggressive surgical debridement and broad-spectrum antibiotics.

Evaluation of Negative Pressure Wound Therapy in the Management of Fournier's Gangrene.

Introduction Necrotizing soft tissue infections (NSTIs), including Fournier's gangrene (FG), are severe polymicrobial bacterial infections characterized by rapidly spreading inflammation and tissue necrosis. This study aims to compare the clinical outcomes of vacuum-assisted closure (VAC) dressing and conventional dressing in patients with FG. Materials and methods A prospective study was conducted from December 2020 to May 2022, including patients with clinical features suggestive of FG. Patients were divided into two groups: conventional dressing and VAC dressing. Relevant clinical data, including age, duration of hospital stay, wound status, Fournier's gangrene severity index (FGSI) scores, sepsis markers (C-reactive protein (CRP), neutrophil-to-lymphocyte ratio, and procalcitonin), and pain assessment, were recorded and compared between the two groups. Results A total of 84 patients were included in the study, with 42 patients in each group. The mean age was 57.48 ± 15.74 years in the conventional dressing group and 50.83 ± 13.95 years in the VAC dressing group. VAC dressing was associated with a significantly shorter duration of hospital stay (8.14 ± 3.13 days) compared to conventional dressing (11.36 ± 4.75 days). The average time taken for wound closure was significantly reduced in the VAC dressing group (63 ± 14.81 days) compared to the conventional dressing group (112.56 ± 13.82 days). FGSI scores showed significant improvement after debridement in both groups, with lower scores in the VAC dressing group at discharge. Sepsis markers such as CRP and serum procalcitonin exhibited a significant decrease after VAC application. Discussion The study demonstrates that VAC therapy is associated with better clinical outcomes in FG, including reduced duration of hospital stay, faster wound closure, improved FGSI scores, decreased sepsis markers, and reduced pain. These findings align with previous studies highlighting the advantages of VAC therapy over conventional dressing methods. Conclusion VAC therapy provides significant benefits in the management of FG, leading to improved clinical outcomes and patient quality of life. It offers advantages such as shorter hospital stays, faster wound closure, and reduced sepsis markers. The application of VAC dressing should be considered a valuable treatment modality for FG.

Biomarkers to predict mortality in patients with Fournier's gangrene admitted to the intensive care unit after surgery in South Korea.

BACKGROUND: The use of biomarkers to predict patient outcomes may be crucial for patients admitted to the intensive care unit (ICU) following surgery because biomarkers guide clinicians in tailoring treatment plans accordingly. Therefore, we aimed to identify potential biomarkers to predict the prognosis of patients with Fournier's gangrene (FG) admitted to the ICU after surgery. METHODS: We enrolled patients with FG admitted to our Hospital between January 2013 and December 2022. We retrospectively analyzed patient characteristics, factors related to management, scores known to be associated with the prognosis of FG, and laboratory data. RESULTS: The study population included 28 survivors and 13 nonsurvivors. The initial serum lactate level taken in the emergency department; white blood cell, neutrophil, and platelet counts; delta neutrophil index and international normalized ratio; albumin, glucose, HCO3, and postoperative lactate levels; and the laboratory risk indicator for necrotizing fasciitis differed between survivors and nonsurvivors. Postoperative lactate and initial albumin levels were independent predictors of mortality in patients with FG. In the receiver operating characteristic curve analysis, the postoperative lactate level was the best indicator of mortality (area under the curve, 0.877; 95% confidence interval, 0.711-1.000). The optimal cutoff postoperative lactate level for predicting mortality was 3.0 mmol/L (sensitivity, 80.0%; specificity, 95.0%). CONCLUSIONS: Postoperative lactate and initial albumin levels could be potential predictors of mortality in patients with FG admitted to the ICU after surgery, and the optimal cutoff postoperative lactate and initial albumin levels to predict mortality were 3.0 mmol/L and 3.05 g/dl, respectively. Large-scale multicenter prospective studies are required to confirm our results.

Fournier gangrene - would you KISS it?

Fournier gangrene is a disease characterized by necrotizing fasciitis of the perineal and genital region, resulting from synergistic polymicrobiotic infection. Most infections can be localized to a cutaneous, urethral, or rectal source and can culminate in a fulminant sepsis. Current state of the art is systemic broad-spectrum antibiotics and serial aggressive debridement which result in superficial perineal defect of wide dimensions. We compiled all the cases of Fournier gangrene that required reconstruction after debridement in Centro Hospitalar Universitário Lisboa Central from 2018 to 2022. Inclusion criteria were reconstruction for Fournier defects and patients' age 18 to 90 years old. Exclusion criteria were patients who didn't require reconstruction or didn't complete it due to death or transfer to another healthcare institution. Reconstructive procedures and complication rates are reported as whole numbers and percentages of total. The initial search yielded 32 patients. There were 2 (6.2%) patients with defects that healed by secondary intention, 6 (18.7%) with delayed primary closure, 4 (12.5%) with implantation of the testicle in a medial thigh pocket, 12 (37.5%) with skin grafts, 4 (12.5%) with scrotal advancement flaps, 2 (6.2%) with flaps, and 2 (6.2%) with flaps and skin grafts in combination. Four outcomes were evaluated: number of patients, defect size, method of reconstruction, and wound-healing complications. Most reconstructive techniques provide reliable coverage and protection of testicular function with an acceptable cosmetic result. The reconstructive options need to be patient tailored in order to achieve long lasting results with a minimum of postoperative morbidity.

Role of High-Resolution Ultrasonography With Colour and Duplex Doppler in the Evaluation of Acute Scrotal Diseases.

Introduction The term 'acute scrotum' denotes the sudden initiation of pain in the scrotal region. Acute scrotum is a frequent medical condition in children and adults. Ultrasound facilitates precise diagnosis and differentiation of numerous causes of acute scrotum. The objective of our research was to assess the utility of ultrasonography in the identification and prevalence determination of causes of acute scrotum. Materials and methods Patients with acute scrotal pain referred to the Department of Radiodiagnosis at Great Eastern Medical School & Hospital (GEMS), Srikakulam, India, were added in the research. This is a prospective observational study. High-frequency linear transducer (4-15 MHz) was used for imaging. Grey scale, colour and duplex Doppler were performed routinely. The ultimate diagnosis was established by considering the clinical results, follow-up observations, intraoperative observations and, when accessible, histopathological analysis. For the statistical analysis, IBM SPSS Statistics for Windows, version 22 (released 2013; IBM Corp., Armonk, New York, United States). was used. Descriptive analysis was conducted. The Kendall rank correlation coefficient was used to evaluate the non-parametric association between side and torsion. Results A total of 120 patients were included for statistical analysis. Inflammatory pathology was the most common cause of acute scrotum, followed by testicular torsion and torsion of testicular appendage. Testicular torsion and side of pain did not show a significant association. Conclusion High-resolution ultrasonography with colour and duplex Doppler sonography is an excellent imaging modality exhibiting exceptional sensitivity and specificity for the accurate diagnosis of acute scrotal diseases. Inflammatory pathology was the most common cause of acute scrotum, followed by testicular torsion and torsion of the testicular appendage.

Fournier's Gangrene Secondary to Perforated Sigmoid Adenocarcinoma Within an Incarcerated Inguinal Hernia.

Colon cancer is the third most common cancer worldwide. Approximately one-fifth of colon cancers will present emergently due to obstruction or perforation. Necrotizing soft tissue infection is a rare presentation of perforated colon cancer and represents a surgical emergency due to high mortality rate.  A man in his 80s presented with several days of scrotal pain and weakness. On physical exam he was found to have scrotal edema and erythema and bilateral inguinal hernias. Imaging revealed a large scrotal abscess and concern for necrotizing soft tissue infection. He was taken to the operating room for surgical debridement and exploration and was discovered to have perforated colon within an incarcerated inguinal hernia. He underwent exploratory laparotomy with sigmoid resection and end colostomy creation. Pathology returned demonstrating invasive sigmoid adenocarcinoma. Fournier's gangrene requires a high index of suspicion. It is a rapidly progressing infection associated with high mortality. Early initiation of antibiotics and surgical debridement are mainstays of treatment. When associated with perforated colonic malignancy, workup must include imaging of the chest, abdomen, and pelvis as well as carcinoembryonic antigen (CEA) level to complete staging. Fournier's gangrene secondary to perforated sigmoid adenocarcinoma is a unique presentation. Treatment first involves antibiotics and aggressive surgical debridement. Once the patient is stabilized, further oncologic workup should be completed to determine treatment course.

Introduction: Fournier's gangrene is currently defined as a specific form of synergistic, rapid, progressive and multibacterial necrotizing fasciitis, which mainly affects the muscular fascia of the perineal, genital, or perianal region and even the abdominal wall; with genitourinary, colorectal, or idiopathic starting point. All of this, accompanied by skin gangrene in these areas due to thrombosis of subcutaneous blood vessels. Objectives: To describe the epidemiological and surgical characteristics of the sequelae patients of Fournier's disease in the Plastic Surgery Unit of the Hospital de Clínicas in a period of 2 years. Materials and methods: Observational, descriptive, cross-sectional, temporally retrospective, case series type study. The type of sampling was non-probabilistic at convenience. Eighteen sequelae patients of Fournier's disease reconstructed in the Plastic Surgery Unit of Hospital de Clínicas between 2020 and 2021 are presented. Results: During the study period, 395 surgeries were performed in the Plastic Surgery Service of the Hospital de Clínicas, of which 18 patients underwent surgery for sequelae of Fournier's disease, which represents 5% of the total. Regarding demographic variables, age ranged between 37 and 85 years with greater impact in the sixth decade of life with an average of 61 years. 94% of the patients were male; 89% of the patients had type 2 diabetes mellitus as an underlying pathology, followed by obesity in 72% and high blood pressure in 56% of cases; In 83% of the cases, the scrotal region was affected, followed by the perineal region in 56% of the patients and the penis in 50% of the cases. The most frequently used reconstructive technique was flaps in 10 patients, followed by skin grafting in 8 patients, and primary closure in 6 patients. It is worth mentioning that in some patients several reconstructive techniques were used following the concept of reconstruction by sub- anatomical units, among the flaps the most used were the medial femoral circumflex perforator flap (gracilis perforator) with 50% of the cases followed by the fasciocutaneous transposition flap of the internal pudendal with 30%, and finally the fasciocutaneous advancement flap with 20% (Table 3). The average hospital stay was 3 days, with a minimum of 1 day and a maximum of 5 days postoperatively. Suture dehiscence was reported as a complication in 3 patients; no complications were observed in 77% of the cases. Conclusion: The sequelae of Fournier's disease undergoing surgeries represent 5% of the total number of surgeries performed in our Service, they are more prevalent in the sixth decade of life, it affects more males with type 2 diabetes mellitus as the underlying pathology, the reconstructive techniques used in the sequelae are variable according to the anatomical regions affected and can range from primary closure to the use of flaps for repair.
