In addition to broad-spectrum parental antibiotics, early and aggressive surgical debridement has been shown to improve survival in patients presenting with FG as patients often undergo more than one debridement during their hospitalization [ Corman et al.

As mentioned previously, testicular involvement in FG is rare and suggests an intraabdominal or retroperitoneal source [ Eke, ]. This finding is likely attributable to more aggressive diagnosis and management of FG at experienced hospitals. Material and Methods We carried out a retrospective study of 37 patients diagnosed with Fournier gangrene between January and October It is a necrotizing fasciitis caused by polymicrobial infection originating in the anorectal fisiopatlogia genitourinary area.

The aerobic bacteria cause platelet aggregation and induce complement fixation, thereby causing acceleration of coagulation.

Usually the infection starts gangrrena a cellulitis adjacent to the portal of entry, commonly in the perineum or perineal region, with an insidious presentation.

As a result of these defects, ensuing exposure of the testicles in the male patient presents a substantial challenge for reconstruction.

By quantifying the severity of infection using common vital signs temperature, heart rate, respiratory rate and laboratory data serum sodium, serum potassium, serum creatinine, serum bicarbonate, hematocrit and white blood cell countthe FGSI score helps prognosticate progression and predict the mortality.

The mean hospital stay was Fecal diversions may have be partially responsible for a higher mean number of surgical procedures in patients treated with VAC therapy compared with those whose wounds were treated with conventional dressings that were more easily changed on the wards.

In 74 patients presenting with FG at an Egyptian medical center, adequate urinary diversion was accomplished with the use of a urethral Foley catheter in all but one patient who had experienced a urethral injury.

Surg Gynecol Obstet The aim of this study was to analyze the epidemiological and clinical characteristics of Fournier gangrene along with the variables that influence disease course and mortality in patients treated in our department. In patients infected with methicillin-resistant S. Moreover, many have suggested adding penicillin for treatment of streptococci and, in particular, when Clostridia is suspected.

All articles are subjected to a rigorous process of revision in pairs, and careful editing for literary and scientific style. Moreover, response to treatment was found to be expedited in those treated with fisiopatklogia honey [ Efem, ]. Postoperative erections were achieved in four of the six patients who were able to achieve erections preoperatively.

Loose wound edge closure was achieved with a nonabsorbable monofilament suture by U-stitch approximation of the scrotal or perineal wound edges [ Akilov et al. Group A streptococcal is the most common cause of monomicrobial necrotizing fasciitis [ Ekelius et al.

FG is a rare necrotizing fasciitis of the perineal, genital and perianal region with an aggressive clinical course.

After extensive debridement, many fisiopaologia sustain significant defects of the skin and soft tissue, fisiopatooogia a need for reconstructive surgery for satisfactory functional and cosmetic results. Conclusions Fournier gangrene is associated with high mortality despite appropriate early treatment.

Early diagnosis remains imperative, as the rate of fascial necrosis has been noted as high as 2—3 cm per hour [ Uppot et al. Am J Sur In a review of 26 cases of FG treated at a university medical center, Hollabaugh and colleagues utilized suprapubic diversion in fislopatologia cases with 15 of those patients receiving diversion at the time of initial debridement. In their study of 44 patients presenting with FG, Ozturk and colleagues found that in 18 patients that required temporary stoma formation, significant increases in healthcare costs were observed without an effect on outcomes.

The degree of deviation from normal is graded from 0 to 4, and individual values are summed to obtain the FGSI score. This article has been cited by other articles in PMC. Ann R Coll Surg Engl In a retrospective study of 19 patients diagnosed with FG, Chawla and colleagues studied the utilization of the FGSI to determine length of stay and survival.

Can J Surg Investigations Despite timely and aggressive treatment, the mortality rate for FG remains high [ Morpurgo and Galandiuk, ; Sorensen et al. It was found that more FG cases were treated per year at teaching hospitals where more surgical procedures, debridements and supportive care were reported. The study of STSGs in the setting of denuded genitalia has been extensively studied and dates back to when Campbell first applied the technique to the testis after traumatic avulsion of the scrotum.

Czymek and colleagues prospectively collected data on 35 patients diagnosed with FG to assess the effectiveness of VAC therapy versus daily antiseptic polyhexadine dressings. This impaired blood supply furthers perifascial dissection with spread of bacteria and progression to gangrene of the overlying subcutaneous tissue and skin.

However, split-thickness skin grafts STSGs are preferred over FTSGs for trauma, avulsions, burns and hidradenitis suppurativa because of better take in these contaminated wounds. Moreover, a drain was left in place to allow for irrigation of the graft with Sulfamylon for the first 5 days.

Four of the gangrna patients experienced genital skin loss secondary to FG. Go to the members area of the website of the AEDV, https: Overall, the authors conclude that meshed STSGs provide a simple and reproducible technique fournler skin coverage after cisiopatologia skin debridement of the genitals with adequate cosmetic and functional results [ Black et al. The anaerobic bacteria promote the formation of clots by producing collagenase and heparinase.

Since the treatment of FG often requires highly acute and intensive multidisciplinary care, Sorensen and colleagues examined the difference in case severity and management between teaching and nonteaching hospitals. Pathogenesis and organisms involved The predisposing and etiologic factors of FG provide a favorable environment for the infection by decreasing the host immunity and allowing a portal of entry for the microorganism into the perineum.

The polymicrobial nature of FG with contributions by both aerobic and anaerobic bacteria is necessary to create the production of various exotoxins and enzymes like collagenase, heparinase, hyaluronidase, streptokinase and streptodornase, which promote rapid multiplication and spread of infection.
