Abstract Management of complex diabetic foot wounds with large skin defects poses a challenge for surgeon. We presented a simple skin stretching system and negative pressure wound therapy for the repair of complex diabetic foot wounds to examine the effectiveness and safety.A total of 16 patients with diabetic foot ulcers were retrospectively reviewed between January 2015 to October 2020. All patients underwent the treatment by 3 stages. In stage 2, these difficult-to-close wounds of diabetes foot were residual. This method was applied to the wounds with a median defect size of 20.42 cm² (range: 4.71 -66.76 cm²).The median time for closure of complex diabetic foot wounds was 14 days ranging from 8 days to 19 days. With respect to the absolute rates of reduction, it was observed with a median of 1.86 cm² per day, ranging from 0.29 cm² per day to 8.35 cm² per day. In accordance with the localization of the defect, the patients were divided into 3 groups: side of the foot (37.5%), dorsum of the foot (50.0%), and others (12.5%). There was no statistically difference between side of the foot and dorsum of the foot in terms of the median defect size with P = 0.069 (Kruskal–Wallis test). Otherwise, there were statistically significant differences regarding the median time and the median absolute rates (P < 0.05; Kruskal–Wallis test). No severe complications were encountered in this study.In summary, our results show that application of the simple skin stretching system and NPWT is an effective and safe approach for complex diabetic foot wounds. Nevertheless, more attentions should be paid for the appropriate patient selection and intraoperative judgment to ensure wound closure and avoid undue complications.

Objective: Mechanical negative pressure wound therapy is an ultraportable, light weight and disposable single-use device that has been shown to promote wound healing. This study evaluated home use of a mechanically powered negative pressure wound therapy (NPWT) in diabetic foot wounds. Methods: Patients underwent revascularisation and/or debridement or amputation before starting mechanical NPWT. Wound outcomes and images of the wounds were recorded at each follow-up visit by the wound nurse. Patients were followed up until wound closure or end of therapy. Results: A total of 12 patients (each with one wound) were included in the study. Of the 12 wounds, 33.3% (n=4) of wounds achieved primary wound closure while the remaining 66.6% (n=8) of wounds demonstrated a mean wound size reduction of 37.5±0.13%. Of the closed wounds, mean time to healing was 4.75±2.50 weeks. There was 100% limb salvage with no further debridement or amputations, and no 30-day unplanned readmissions. Mean length of hospital stay before starting home NPWT was 9.75±6.31 days. Mean number of NPWT changes was 8.33±2.67 sessions, while mean duration of therapy was 4.0±1.54 weeks. Mean cost of home NWPT therapy was US$1904±731 per patient. Conclusion: The home use of mechanically powered NPWT in diabetic foot wounds demonstrated excellent wound healing rates and 100% limb salvage, with no complications.

Background We conducted a post-hoc retrospective analysis of patients enrolled in a randomized controlled trial to evaluate overall costs of negative pressure wound therapy (NPWT; V.A.C. Therapy; KCI USA, Inc, San Antonio, Texas) versus advanced moist wound therapy (AMWT) in treating grade 2 and 3 diabetic foot wounds during a 12-week therapy course. Methods Data from two study arms (NPWT [n = 169] or AMWT [n = 166]) originating from Protocol VAC2001-08 were collected from patient records and used as the basis of the calculations performed in our cost analysis. Results A total of 324 patient records (NPWT = 162; AMWT = 162) were analyzed. There was a median wound area reduction of 85.0% from baseline in patients treated with NPWT compared to a 61.8% reduction in those treated with AMWT. The total cost for all patients, regardless of closure, was $1,941,472.07 in the NPWT group compared to $2,196,315.86 in the AMWT group. In patients who achieved complete wound closure, the mean cost per patient in the NPWT group was $10,172 compared to $9,505 in the AMWT group; the median cost per 1 cm2 of closure was $1,227 with NPWT and $1,695 with AMWT. In patients who did not achieve complete wound closure, the mean total wound care cost per patient in the NPWT group was $13,262, compared to $15,069 in the AMWT group. The median cost to close 1 cm2 in wounds that didn't heal using NPWT was $1,633, compared to $2,927 with AMWT. Conclusions Our results show greater cost effectiveness with NPWT versus AMWT in recalcitrant wounds that didn't close during a 12-week period, due to lower expenditures on procedures and use of health-care resources.

ObjectivesThe aim of the DiaFu study was to evaluate effectiveness and safety of negative pressure wound therapy (NPWT) in patients with diabetic foot wounds in clinical practice.DesignIn this controlled clinical superiority trial with blinded outcome assessment patients were randomised in a 1:1 ratio stratified by study site and ulcer severity grade using a web-based-tool.SettingThis German national study was conducted in 40 surgical and internal medicine inpatient and outpatient facilities specialised in diabetes foot care.Participants368 patients were randomised and 345 participants were included in the modified intention-to-treat (ITT) population. Adult patients suffering from a diabetic foot ulcer at least for 4 weeks and without contraindication for NPWT were allowed to be included.InterventionsNPWT was compared with standard moist wound care (SMWC) according to local standards and guidelines.Primary and secondary outcome measuresPrimary outcome was wound closure within 16 weeks. Secondary outcomes were wound-related and treatment-related adverse events (AEs), amputations, time until optimal wound bed preparation, wound size and wound tissue composition, pain and quality of life (QoL) within 16 weeks, and recurrences and wound closure within 6 months.ResultsIn the ITT population, neither the wound closure rate (difference: n=4 (2.5% (95% CI−4.7% – 9.7%); p=0.53)) nor the time to wound closure (p=0.244) was significantly different between the treatment arms. 191 participants (NPWT 127; SMWC 64) had missing endpoint documentations, premature therapy ends or unauthorised treatment changes. 96 participants in the NPWT arm and 72 participants in the SMWC arm had at least one AE (p=0.007), but only 16 AEs were related to NPWT.ConclusionsNPWT was not superior to SMWC in diabetic foot wounds in German clinical practice. Overall, wound closure rate was low. Documentation deficits and deviations from treatment guidelines negatively impacted the outcome wound closure.Trial registration numbersNCT01480362and DRKS00003347.

Abstract Purpose Traditionally, previous wound infection was considered a contraindication to secondary skin closure; however, several case reports describe successful secondary wound closure of wounds “preconditioned” with negative pressure wound therapy (NPWT). Although this has been increasingly applied in daily practice, a systematic analysis of its feasibility has not been published thus far. The aim of this study was to evaluate secondary skin closure in previously infected abdominal wounds following treatment with NPWT. Methods Single-center retrospective analysis of patients with infected abdominal wounds treated with NPWT followed by either secondary skin closure referenced to a group receiving open wound therapy. Endpoints were wound closure rate, wound complications (such as recurrent infection or hernia), and perioperative data (such as duration of NPWT or hospitalization parameters). Results One hundred ninety-eight patients during 2013–2016 received a secondary skin closure after NPWT and were analyzed and referenced to 67 patients in the same period with open wound treatment after NPWT. No significant difference in BMI, chronic immunosuppressive medication, or tobacco use was found between both groups. The mean duration of hospital stay was 30 days with a comparable duration in both patient groups (29 versus 33 days, p = 0.35). Interestingly, only 7.7% of patients after secondary skin closure developed recurrent surgical site infection and in over 80% of patients were discharged with closed wounds requiring only minimal outpatient wound care. Conclusion Surgical skin closure following NPWT of infected abdominal wounds is a good and safe alternative to open wound treatment. It prevents lengthy outpatient wound therapy and is expected to result in a higher quality of life for patients and reduce health care costs.

Abstract Introduction Complex wounds (CW) resulting from necrotizing soft tissue infections (NSTIs) and soft tissue traumatic injuries create unique challenges. Radical debridement is often the first step in management but can result in disfigurement with impaired function and compromised cosmesis. The standard of care at our institution for full-thickness burn injuries of similar complexity is widely meshed autografting with application of autologous skin cell suspension (ASCS). Our study is a case series reviewing outcomes using ASCS for CW from non-burn etiology. Methods A retrospective chart review from March 2019 through July 2020 was performed to evaluate the effectiveness of ASCS and widely meshed autografting in CW. Patients presenting with CW underwent serial excisions of devitalized tissue by acute care and burn surgeons. Dermal substitute utilization for wound preparation was at the discretion of the surgeon. Definitive wound closure was achieved using ASCS in combination with a widely meshed autograft. The wounds were covered with a non-adherent, non-absorbent, small pore primary dressing along with bismuth-impregnated, petroleum-based gauze or negative pressure wound therapy dependent on wound bed contour. Further padding with gauze was applied along with compressive dressing. Results In total, 8 patients with CW were included in this review. The mean age was 58 years (range 27-85) with an equal number of males and females. Wound etiology included NSTI (n=5), degloving injury (n=2), and traumatic amputation (n=1). The average wound size measured 1,300cm2 (range 300-3,000). 50% of the patients were treated with a dermal substitute and negative pressure wound therapy prior to ASCS and autograft placement. 7 of 8 patients received split-thickness skin grafting in the ratio of 3:1 with one patient grafted at a 2:1 expansion. 7 of the 8 patients had &gt;90% wound closure within 8-10 days of ASCS and autograft application. One patient had significant graft failure after removing surgical dressings and autograft in the early post-operative period secondary to dementia. One patient expired during the follow-up period secondary to medical comorbidities. The 6 remaining patients had durable wound closure and acceptable cosmetic outcome. All patients were discharged within 10 days of ASCS application with 4 patients discharging home and 4 patients discharging to an acute inpatient rehabilitation. Conclusions This study is the first case series to review ASCS in combination with widely meshed skin grafts in the management of CW from a non-burn etiology. Durable, timely wound closure and an acceptable cosmetic outcome was achieved in these often-challenging CW.
