Comparing the hydrosurgery system to conventional debridement techniques for the treatment of delayed healing wounds: a prospective,randomised clinical trial to investigate clinical efficacy and cost‐effectiveness

In these uncertain times of high health care costs, clinicians are looking for cost‐effective devices to employ in their everyday practices. In an effort to promote cost‐effective and proper wound repair, the hydrosurgical device allows accurate debridement of only unwanted tissue while precisely conserving viable structures for eventual repair. This prospective, randomised study compared procedures using the hydrosurgery system (VERSAJET?) with conventional debridement in order to assess clinical efficacy and cost‐effectiveness when treating subjects with chronic wounds. A total of 40 subjects were recruited. There was no difference in time to achieve stable wound closure between the treatment groups (P = 0·77). There were no significant differences between the two groups in terms of cost of the first operative procedure (P = 0·28), cost of surgical procedures during the study (P = 0·51), cost of study treatment (P = 0·29) or cost to achieve stable wound closure (P = 0·85). There were no differences in quantitative bacterial counts after debridement with either methods (P = 0·376). However, the time taken for the first excision procedure was significantly faster using the hydrosurgery system (VERSAJET) when compared with conventional debridement (P < 0·001). The total excision time for all procedures was significantly less for the Hydrosurgery group than for the conventional group (P = 0·005). Also, the Hydrosurgery group demonstrated significantly less intraoperative blood loss than conventional group for all procedures (P = 0·003). In this study, although there were no differences in time to stable wound closure or bacterial reduction between the two groups, the hydrosurgery system (VERSAJET) did offer advantages in terms of operative times and intraoperative blood loss and was cost‐neutral, despite the handpiece cost.     

Efficacy of Versajet hydrosurgery system in chronic wounds: A systematic review

Studies demonstrating the effectiveness of hydrosurgery for chronic wounds are extremely limited. This systematic review aimed to evaluate the efficacy of hydrosurgery compared with conventional debridement in chronic wounds, skin ulcers, and non‐acute wounds. This PROSPERO‐registered review was performed following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses statement. A systematic search was performed in PubMed, Scopus, and Cochrane Library databases. Abstracts of all studies were screened independently by two reviewers. The bias of prospective randomised controlled studies was assessed using the Cochrane Collaboration''s tool for assessing the risk of bias and RevMan 5.4 software, whereas the bias of retrospective comparative studies was evaluated using the Risk of Bias Assessment Tool for Non‐randomised Studies. Two prospective randomised controlled trials, two retrospective comparative studies, and three prospective non‐comparative studies were included. Hydrosurgery enabled rapid debridement. The Versajet Hydrosurgery System saved 8.87 minutes compared with the conventional methods. Similarly, the debridement quality was high with this system. The debridement number needed to achieve adequate wound beds was fewer in the hydrosurgery group than in the conventional group. These superiorities lead to subsequent success and cost‐effectiveness. As there were only two prospective randomised controlled studies, and much information was missing, the risk of bias was unclear. This review confirmed that hydrosurgery is useful for the debridement of chronic wounds, considering the procedural speed and quality.

A prospective evaluation of lower extremity ulcers in a Zimbabwean population

Aetiological factors and their frequencies, causes, level and impact of immunosuppression on outcome of lower extremity ulcers were prospectively recorded. A total of 100 patients were evaluated. Consent for HIV testing was given by 68 patients and 31 (46%) of these were HIV infected. Thirty patients were diabetic. CD 4+ T‐lymphocyte count was assessed in 41 patients. Eleven were HIV infected with a mean CD 4+ count of 229 ± 137 cells/µl. Six had non insulin‐dependent diabetes mellitus (NIDDM) with a mean CD 4+ count 430 ± 308 cells/µl. Five had both HIV infection and NIDDM with a mean CD 4+ count of 299 ± 120 cells/µl. All three groups differed from the normal 707 ± 285 cells/µl found in 17 non HIV‐infected non diabetic patients (P < 0· 05). The main aetiologies were bacterial infection, arterial disease, trauma and neuropathy. Ulcer healing and limb salvage were noted in 71%. Mortality was 10%; seven in HIV‐infected and three in non HIV‐infected non diabetic patients (P = 0· 06). Amputation rate was 9%. Persisting ulcers were noted in 8% and 2% were lost to follow‐up. Our evaluation shows that wound aetiologies in Zimbabwe differ from those in the West. Immunosuppression because of HIV infection and NIDDM was noted in more than half of the patients. HIV infection may increase mortality in this group of patients.

An electrical plasma dissection tool for surgical treatment of chronic ulcers: Results of a prospective randomised trial

Cutaneous ulceration is a difficult medical problem and a major source of morbidity for patients. In the surgical treatment of ulcers, debridement is the first step, and it can be carried out using several surgical tools. Recently, new surgical devices have emerged using plasma‐mediated electrical discharges with a lower peak temperature. A prospective single‐blind trial was conducted on chronic ulcers not responsive to common non‐surgical management. Patients were randomly separated into 2 groups: Group A received surgical debridement with conventional electrocautery, and Group B received surgical debridement using the plasma‐mediated device. Histological samples were collected intraoperatively to evaluate the thermal damage during the surgical procedure and 2 weeks after surgery to evaluate the inflammatory response and collagen deposition. The width of coagulation necrosis at the incision margins in Group B was significantly shorter compared with Group A (P = .001). The inflammatory cell infiltration showed a cellular distribution percentage that was quite equal between the 2 groups. The granulation tissue showed an abundant deposition of dense and mature collagen in Group B, compared with Group A, where the mature collagen appeared in small quantities (P < .001). Microbial culture showed a lower incidence of postoperative infections in Group B compared with the control group (P < .05). The study demonstrated, based on the results, that the new technology with the use of a lower temperature electrosurgical device represents an effective therapeutic weapon for the surgical treatment of skin ulcers, both vascular and extravascular types.     

Reliability of the mangled extremity severity score in combat-related upper and lower extremity injuries

Background:Decision of limb salvage or amputation is generally aided with several trauma scoring systems such as the mangled extremity severity score (MESS). However, the reliability of the injury scores in the settling of open fractures due to explosives and missiles is challenging. Mortality and morbidity of the extremity trauma due to firearms are generally associated with time delay in revascularization, injury mechanism, anatomy of the injured site, associated injuries, age and the environmental circumstance. The purpose of the retrospective study was to evaluate the extent of extremity injuries due to ballistic missiles and to detect the reliability of mangled extremity severity score (MESS) in both upper and lower extremities.Results:Amputation was performed in 39 extremities and limb salvage attempted in 100 extremities. The mean followup time was 14.6 months (range 6–32 months). In the amputated group, the mean MESS scores for upper and lower extremity were 8.8 (range 6–11) and 9.24 (range 6–11), respectively. In the limb salvage group, the mean MESS scores for upper and lower extremities were 5.29 (range 4–7) and 5.19 (range 3–8), respectively. Sensitivity of MESS in upper and lower extremities were calculated as 80% and 79.4% and positive predictive values detected as 55.55% and 83.3%, respectively. Specificity of MESS score for upper and lower extremities was 84% and 86.6%; negative predictive values were calculated as 95.45% and 90.2%, respectively.Conclusion:MESS is not predictive in combat related extremity injuries especially if between a score of 6–8. Limb ischemia and presence or absence of shock can be used in initial decision-making for amputation.     

Effect of diabetic foot ulcers and other risk factors on the prevalence of lower extremity amputation: A meta-analysis

A meta-analysis study was conducted to measure the consequence of diabetic foot ulcers (DFUs) and other risk factors (RFs) on the prevalence of lower extremity amputation (LEA). A comprehensive literature inspection till February 2023 was applied and 2765 interrelated studies were reviewed. Of the 32 chosen studies enclosed, 9934 subjects were in the chosen studies' starting point, and 2906 of them were with LEA. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to compute the value of the effect of DFUs and other RFs on the prevalence of LEA by the continuous and dichotomous approaches and a fixed or random effect model. Male gender (OR, 1.30; 95% CI, 1.17–1.44, P < .001), smoking (OR, 1.24; 95% CI, 1.01–1.53, P = .04), previous foot ulcer (OR, 2.69; 95% CI, 1.93–3.74, P < .001), osteomyelitis (OR, 3.87; 95% CI, 2.28–6.57, P < .001), gangrene (OR, 14.45; 95% CI, 7.03–29.72, P < .001), hypertension (OR, 1.17; 95% CI, 1.03–1.33, P = .01), and white blood cells count (WBCC) (MD, 2.05; 95% CI, 1.37–2.74, P < .001) were significantly shown to be an RF in LEA in subjects with DFUs. Age (MD, 0.81; 95% CI, −0.75 to 2.37, P = .31), body mass index (MD, −0.55; 95% CI, −1.15 to 0.05, P = .07), diabetes mellitus type (OR, 0.99; 95% CI, 0.63–1.56, P = .96), and glycated haemoglobin (MD, 0.33; 95% CI, −0.15 to 0.81, P = .17) were not shown to be an RF in LEA in subjects with DFUs. Male gender, smoking, previous foot ulcer, osteomyelitis, gangrene, hypertension, and WBCC were significantly shown to be an RF in LEA in subjects with DFUs. However, age and diabetes mellitus type were not shown to be RF in LEA in subjects with DFUs. However, caused of the small sample sizes of several chosen studies for this meta-analysis, care must be exercised when dealing with its values.     

The efficacy of topical royal jelly on healing of diabetic foot ulcers: a double‐blind placebo‐controlled clinical trial

Foot ulcers are major sources of morbidity in individuals with diabetes mellitus. As royal jelly (RJ, a worker honey bee product) contains enzymatic, antibacterial and vasodilative properties, it can potentially help in healing of diabetic foot ulcers (DFUs). This study aimed to evaluate the efficacy of topical RJ on healing of DFUs. Diabetic patients with foot ulcers who were referred to us at Khorshid Hospital, Isfahan, Iran, were managed by offloading, infection control, vascular improvement and debridement (if required). Then, all ulcers were randomly selected to receive either 5% sterile topical RJ or placebo on their total surface area. Patients were followed for 3 months or until complete healing. Twenty‐five patients (6 females and 19 males) and a total of 64 ulcers were included and randomly allocated to case or control group (32 per group). Four ulcers were excluded and 60 ulcers included in the final analysis. Healing parameters including depth, length and width reduction rate, duration of complete healing and incidence of complete healing did not show any significant difference (P = 0·69, 0·95, 0·7, 0·74 and 0·6, respectively) between groups. We did not observe any side effect of topical RJ application. This study could not confirm any significant superiority of 5% topical RJ over placebo for the treatment of DFUs.     

Serial surgical debridement: A retrospective study on clinical outcomes in chronic lower extremity wounds

This investigation was conducted to determine if a correlation exists between wound healing outcomes and serial debridement in chronic venous leg ulcers (VLUs) and diabetic foot ulcers (DFUs). We retrospectively analyzed the results from two controlled, prospective, randomized pivotal trials of topical wound treatments on 366 VLUs and 310 DFUs over 12 weeks. Weekly wound surface area changes following debridement and 12-week wound closure rates between centers and patients were evaluated. VLUs had a significantly higher median wound surface area reduction following clinical visits with surgical debridement as compared with clinical visits with no surgical debridement (34%, p =0.019). Centers where patients were debrided more frequently were associated with higher rates of wound closure in both clinical studies ( p =0.007 VLU, p =0.015 DFU). Debridement frequency per patient was not statistically correlated to higher rates of wound closure; however, there was some minor evidence of a positive benefit of serial debridement in DFUs (odds ratio—2.35, p =0.069). Our results suggest that frequent debridement of DFUs and VLUs may increase wound healing rates and rates of closure, though there is not enough evidence to definitively conclude a significant effect. Future clinical research in wound care should focus on the relationship between serial surgical wound debridement and improved wound healing outcomes as demonstrated in this study.     

Intermediate-level disinfection with accelerated hydrogen peroxide prevents accumulation of bacteria in Versajet™ tubing during repeated daily debridement using simulated-use testing with an inoculated pork hock

Objective

This study assesses the feasibility of using the Versajet™ system (VJS) on an inoculated pork hock (PH) skin surface sequentially for 8 days with daily cleaning and intermediate-level disinfection (ILD).

Methods

Daily, PHs were inoculated with bacteria suspended in artificial test soil (ATS). An ILD protocol with accelerated hydrogen peroxide (AHP, Oxivir_TB^®) was employed to clean and disinfect the VJS between debridements.

Results

PH skin contains 6.1–6.8 × 10⁶ cfu/cm² bacteria. Bacterial counts in the handpiece and discharge hoses immediately after debridement of the PHs, and before cleaning, increased throughout the study period (5.19–6.43 log₁₀ cfu/mL). Cleaning with the ILD protocol was reduced bacterial counts on the VJS by 6-log. Protein, a surrogate marker of organic contamination, was also reduced post-cleaning and ILD. Compared to a maximum post-debridement level of protein (57.9 μg/mL) obtained before ILD, VJS protein levels dropped to 9.8 (handpiece) and 13.8 μg/mL (discharge hose).

Conclusions

Disinfection of the handpiece and discharge hose after debridement with AHP resulted in a 6-log reduction in bacterial count and 4.2 fold reduction in protein. An ILD protocol with an AHP may be a feasible method for serial skin surface debridements with the VJS for up to eight days.

Enhanced postoperative recovery pathways in emergency surgery: a randomised controlled clinical trial

Background

Enhanced recovery pathways are now widely used in elective surgical procedures. The feasibility of enhanced postoperative recovery pathways in emergency surgery for perforated peptic ulcer disease was investigated in this randomized controlled clinical trial.

Methods

Patients with perforated peptic ulcer disease who underwent laparoscopic repair were randomized into 2 groups. Group 1 patients were managed with standard postoperative care and group 2 patients with enhanced postoperative recovery pathways. The primary endpoints were the length of hospital stay and morbidity and mortality.

Results

Forty-seven patients were included in the study. There were 26 patients in group 1 and 21 in group 2. There were no significant differences in the morbidity and mortality rates, whereas the length of hospital stay was significantly shorter in group 2.

Conclusions

The application of enhanced postoperative recovery pathways in selected patients with perforated peptic ulcer disease who undergo laparoscopic Graham patch repair seems feasible.
