Purpose To explore the role of vacuum assisted closure (VAC) therapy versus conventional dressings in the Fournier's gangrene wound therapy. Patients and Methods This is a retrospective multi-institutional cohort study. Data of 92 patients from nine centers between 2007 and 2018 were retrospectively analyzed. After surgery, patient having a local or a disseminated FG were managed with VAC therapy or with conventional dressings. The 10-weeks wound closure cumulative rate and OS were analyzed. Results Of the 92 patients, 62 (67.4%) showed local and 30 (32.6%) a disseminated FG. After surgery, 19 patients (20.7%) with local and 14 (15.2%) with disseminated FG underwent to VAC therapy; 43 (46.7%) with local and 16 (17.4%) with disseminated FG were treated using conventional dressings. The multivariable logistic regression analysis demonstrated that the VAC in patients with disseminated FG led to a higher cumulative rate of wound closure than patients treated with no-VAC (OR = 6.5; 95% CI 1.1-37.4, p = 0.036). The Kaplan-Meier survival curves for the OS showed a significant difference between no-VAC patients with local and disseminated FG (OS rate at 90 days 0.90, 95% CI 0.71-0.97 vs 0.55, 95% CI 0.24-0.78, respectively; p = 0.039). Cox regression confirmed that no-VAC patients with disseminated FG showed the lowest OS (hazard ratio adjusted for sex and age HR = 3.4, 95% CI 1.1-10.4; p = 0.033). Conclusions In this large cohort study, VAC therapy in patients with disseminated FG may offer an advantage in terms of 10-weeks wound closure cumulative rate and OS at 90 days after initial surgery.

Introduction: To report the long-term multicenter experience with retrograde intrarenal holmium-laser incision (RIR-HoLI) in the management of symptomatic renal sinus cysts (RSCs). In the literature, RIR-HoLI has been shown to be a safe and effective treatment, but there are only a few reports regarding long-term results and reproducibility of this procedure. Material and Methods: From June 2010 to June 2015, 14 patients with symptomatic RSCs underwent RIR-HoLI. The mean age was 52.1 ± 11.28 years (range 28–77) and the mean cyst size was 53.2 ± 14.23 mm (range 35–90). In all cases, contrast-enhanced computer tomography (CT) showed compression of the renal pelvis by the cyst (no malignancy). Surgical outcome was assessed in terms of symptoms improvement (measured by Visual Analogue Scale [VAS] for pain) and renal ultrasound findings at 3–6–12 months postoperatively and then yearly. CT scan was carried out at 12 months follow-up. Results: RIR-HoLI was successful in all patients. The mean operative time was 47.8 ± 13.54 min (range 30–80) and mean hospital stay was 3.5 days (range 2–5). There were 2 Clavien grade II complications (flank pain and urgency delaying discharge). After surgery, all patients ­became asymptomatic (VAS score change, p = 0.0001). One patient had persistence of a small cyst (10 mm). Mean follow-up is 44 ± 17.24 months (range 24–84); all patients remained asymptomatic, with no signs of recurrence. Conclusions: RIR-HoLI proved to be a safe and effective treatment for symptomatic RSCs. In our experience, it provided excellent long-term results and was reproducible at 4 different ­institutions.

Normothermic cardiopulmonary bypass with vacuum assisted venous drainage makes circulatory arrest and hypothermia unnecessary and avoids the potential complications associated with these procedures. With respect to veno-venous shunts this technique guarantees complete surgical control of the thrombus and avoids the need for extensive dissection of the retrohepatic vena cava and Pringle maneuver.

Objectives: To evaluate the role of the microbiological profile and of disease-related factors in the management of patients affected with Fournier’s gangrene (FG). Patients and methods: Data regarding patients admitted for FG at nine Italian Hospitals (March 2007–June 2018) were collected. Patients were stratified according to the number of microorganisms documented: Group A – one microorganism; Group B – two microorganisms; Group C – more than three microorganisms. Baseline blood tests, dedicated scoring systems, predisposing risk factors, disease’s features, management and post-operative course were analyzed. UpSet technique for visualizing set intersections in a matrix layout and Cuzick’s nonparametric test for trend across ordered groups were used. Results: Eighty-one patients were available for the analysis: 18 included in Group A, 32 in Group B, 31 in Group C. The most common microorganism isolated was Escherichia coli. In Group B-C, Escherichia coli was often associated to Enterococcus faecalis, Pseudomonas aeruginosa, and Klebsiella pneumoniae. Statistically significant positive association was highlighted among the number of pathogens (Group A vs B vs C) and serum C-reactive Protein ( p < 0.001), procalcitonin ( p = 0.02) and creatinine ( p = 0.03). Scoring systems were associated with the number of microorganisms detected ( p < 0.02). A significant association between the number of microorganisms and the use of VAC therapy and need of a fecal diversion was found ( p < 0.02). The number of microorganisms was positively associated with the length of stay (LOS) ( p = 0.02). Ten weeks after initial debridement, wound closure was achieved in 11 (91.7%), 22 (84.6%) and 20 (80%) patients in Group A, B, and C, respectively, with no differences in overall survival. Conclusion: Polymicrobial infections in FG are positively associated with inflammatory scores, the need for fecal diversion and the LOS. This results may help the counseling and the clinical management of this rare niche of patients.
