Hydrosurgical and conventional debridement of burns:randomized clinical trial

Background: Tangential excision of burned tissue followed by skin grafting is the cornerstone of burn surgery. Hydrosurgery has become popular for tangential excision, with the hypothesis that enhanced preservation of vital dermal tissue reduces scarring. The aim of this trial was to compare scar quality after hydrosurgical versus conventional debridement before split-skin grafting. Methods: A double-blind randomized within-patient multicentre controlled trial was conducted in patients with burns that required split-skin grafting. One wound area was randomized to hydrosurgical debridement and the other to Weck knife debridement. The primary outcome was scar quality at 12 months, assessed with the observer part of the Patient and Observer Scar Assessment Scale (POSAS). Secondary outcomes included complications, scar quality, colour, pliability, and histological dermal preservation. Results: Some 137 patients were randomized. At 12 months, scars of the hydrosurgical debrided wounds had a lower POSAS observer total item score (mean 2.42 (95 per cent c.i. 2.26 to 2.59) versus 2.54 (95 per cent c.i. 2.36 to 2.72; P =0.023)) and overall opinion score (mean 3.08 (95 per cent c.i. 2.88 to 3.28) versus 3.30 (95 per cent c.i. 3.09-3.51); P = 0.006). Patient-reported scar quality and pliability measurements were significantly better for the hydrosurgically debrided wounds. Complication rates did not differ between both treatments. Histologically, significantly more dermis was preserved with hydrosurgery (P < 0.001). Conclusion: One year after surgery scar quality and pliability was better for hydrosurgically debrided burns, probably owing to enhanced histological preservation of dermis

Long-term scar quality after hydrosurgical versus conventional debridement of deep dermal burns (HyCon trial): Study protocol for a randomized controlled trial

Background: Deep dermal burns require tangential excision of non-viable tissue and skin grafting to improve wound healing and burn-scar quality. Tangential excision is conventionally performed with a knife, but during the last decade hydrosurgery has become popular as a new tool for tangential excision. Hydrosurgery is generally thought to be a more precise and controlled manner of burn debridement leading to preservation of viable tissue and, therefore, better scar quality. Although scar quality is considered to be one of the most important outcomes in burn surgery today, no randomized controlled study has compared the effect of these two common treatment modalities with scar quality as a primary outcome. The aim of this study is, therefore, to compare long-term scar quality after hydrosurgical versus conventional tangential excision in deep dermal burns. Methods/design: A multicenter, randomized, intra-patient, controlled trial will be conducted in the Dutch burn centers of Rotterdam, Beverwijk, and Groningen. All patients with deep dermal burns that require excision and grafting are eligible. Exclusion criteria are: a burn wound 30%, full-thickness burns, chemical or electrical burns, infected wounds (clinical symptoms in combination with positive wound swabs), insufficient knowledge of the Dutch or English language, patients that are unlikely to comply with requirements of the study protocol and follow-up, and patients who are (temporarily) incompetent because of sedation and/or intubation. A total of 137 patients will be included. Comparable wound areas A and B will be appointed, randomized and either excised conventionally with a knife or with the hydrosurgery system. The primary outcome is scar quality measured by the observer score of the Patient and Observer Scar Assessment Scale (POSAS); a subjective scar-assessment instrument, consisting of two separate six-item scales (observer and patient) that are both scored on a 10-point rating scale. Discussion: This study will contribute to the optimal surgi

Health Related Quality of Life in Children After Burn Injuries: A Systematic Review

BACKGROUND: Through improved survival of burns, more children have to deal with consequences of burns. Health-related quality of life (HRQL) measurement is important to qualify the perceived burden of burns in children. No systematic study of this outcome in children exists. Therefore, our objective was to review study designs, instruments, methodological quality, outcomes, and predictors of HRQL in children after burns. METHODS: A systematic literature search was conducted in CINAHL, Embase, Google Scholar, Medline, The Cochrane library, and Web of science (PROSPERO ID, CRD42016048065). Studies examining HRQL in pediatric burn patients were included. The risk of bias was assessed using the Quality in Prognostic Studies (QUIPS) tool. RESULTS: Twenty-seven studies using 12 HRQL instruments were included. The Burns Outcome Questionnaire aged 0 to 4 and 5 to 18 years were most often applied. All longitudinal studies showed improvement of HRQL over time. However, problems were reported on the longer term on the domains "(parental) concern" and "appearance." Parental proxy scores were in general comparable to children's self-ratings. Severity of burns, facial burns, hand burns, comorbidity, and short time since burn predicted an impaired HRQL. The risk of bias of the studies was, in general, moderate. CONCLUSION: Health-related quality of life in children after burns increases over time. Domains and patient groups that require special attention are identified. However, due to lack of comparability of studies, the available information could not be used optimally. To further improve our understanding of HRQL, consensus on design, data-analysis, and data presentation are needed. LEVEL OF EVIDENCE: Systematic review, level III

The pedicled internal pudendal artery perforator (PIPAP) flap for ischial pressure sore reconstruction: Technique and long-term outcome of a cohort study

Background: The ischial region is the site most affected by pressure sores and has the highest recurrence and complication rates compared to other affected sites. We developed a practical and safe pedicled flap for reconstruction of ischial pressure sores based on the rich available perforators from the internal pudendal artery and the surplus of skin at the infragluteal fold. Methods: A retrospective cohort study was conducted in all patients who underwent ischial pressure ulcer reconstruction using the PIPAP flap between March 2010 and March 2017. The skin flap was designed along the gluteal fold. The skin perforators of the pudendal artery were marked with a Doppler probe in the medial region of the gluteal fold. Surgery was performed in the jackknife position, and flaps were elevated in the suprafascial plane. Patients were assessed for minor (requiring no additional surgery) and major complications (requiring additional surgery). Results: Twenty-seven patients (34 flaps) were identified. The median follow-up period was 38 months (IQR 37). Primary closure of the donor-site was achieved in all procedures, only one flap required muscle flap transposition in order to fill the dead space. The mean operating time was 60 ± 21 minutes. In six flaps (9%) wound healing problems were noted that did not require an additional operative procedure. Among the nine flaps (27%) that required a second procedure, 3 (9%) were necessary due to recurrent ulcers. Conclusions: The PIPAP flap is a safe and reliable alternative for ischial pressure sore reconstruction, certainly when compared to available techniques. Moreover, it has significant advantages over other techniques including minimal donor-site morbidity, preservation of posterior thigh skin, buttock-line integrity and reliable vascularity

Surgical outcomes of testicular prostheses implantation in transgender men with a history of prosthesis extrusion or infection

Background: Testicular prostheses implantation may be used for neoscrotal augmentation in transgender men. In current literature, explantation rates range from 0.6% to 30% and most are a result of infection or extrusion. Information on the surgical path of individuals after prosthesis explantation is scarce. Aim: To assess the frequency and success rate of testicular prosthesis implantation after previous explantation due to infection or extrusion. Methods: All transgender men who underwent testicular prosthesis explantation between January 1991 and December 2018 were retrospectively identified from a departmental database. A retrospective chart study was conducted, recording demographics, surgical and prosthesis characteristics, reoperations, and outcomes. Results: A total of 41 transgender men were included who underwent testicular prosthesis explantation in the study time period. Of these, 28 (68%) opted for new prosthesis implantation. Most explanted prosthesis had a volume ≥30cc and were replaced with an equally sized one. The postoperative course was uneventful in 19 out of 28 (68%) individuals. Explantation of one or both prostheses occurred in 7 out of 28 (25%) individuals, because of infection (n = 3, 11%) or extrusion (n = 4, 14%). Patients that experienced complications had more often a history of smoking (p = 0.049). The explantation rate was lower if a smaller or lighter prosthesis was reimplanted (p = 0.020). Discussion: Most patients opt for testicular prosthesis implantation after previous explantation due to extrusion or infection. Explantation rates are higher than after the primary implantation procedure. Results of current study can be used to inform individuals on postoperative outcomes

Brandwonddiepte bepalen met laser-Doppler-imaging

Voor het instellen van de optimale therapie van brandwonden – conservatief of operatief – is een vroege, accurate bepaling van de brandwonddiepte belangrijk. ‘Laser Doppler imaging’ (LDI ) is een techniek waarmee een nauwkeurige inschatting van de brandwonddiepte kan worden gemaakt door het meten van de dermale perfusie. Hoewel is aangetoond dat de keuze voor het wel of niet verrichten van een operatie met LDI eerder kan worden gemaakt, heeft dit niet geleid tot een kortere tijd tot wondgenezing of kostenbesparing in de Nederlandse brandwondenzorg. LDI wordt in alle Nederlandse brandwondencentra gebruikt. Bij twijfel over de brandwonddiepte in de eerste of tweede lijn is doorverwijzing naar een brandwondencentrum raadzaam

Patient-reported scar quality of donor-sites following split-skin grafting in burn patients: Long-term results of a prospective cohort study

Background: Skin grafting is the current gold standard for treatment of deeper burns. How patients appraise the donor-site scar is poorly investigated. The aim of this study was to evaluate long-term patient-reported quality of donor-site scars after split skin grafting and identify possible predictors. Methods: A prospective cohort study was conducted. Patients were included in a Dutch burn centre during one year. Patient-reported quality of donor-site scars and their worst burn scar was assessed at 12 months using the Patient and Observer Scar Assessment Scale (POSAS). Mixed model analyses were used to identify predictors of scar quality. Results: This study included 115 donor-site scars of 72 patients with a mean TBSA burned of 11.2%. The vast majority of the donor-site scars (84.4%) were rated as having at least minor differences with normal skin (POSAS item score ≥2) on one or more scar characteristics and the overall opinion on 80.9% of the donor-site scars was that they deviated from normal skin 12 months after surgery. The overall opinion on the donor-site scar was 3.2 ± 2.1 vs. 5.1 ± 2.4 on the burn scar. A younger age, female gender, a darker skin type, and location on the lower leg were predictors of reduced donor-site scar quality. In addition, time to re-epithelization was associated with scar quality. Conclusion: This study provided new insights in long-term scar quality of donor-sites. Donor-site scars differed from normal skin in a large part of the population 12 months after surgery. Results of this study can be used to inform patients on the long-term outcomes of their scars and to tailor preventive or therapeutic treatment options

Course of scar quality of donor sites following split skin graft harvesting: Comparison between patients and observers

There exists little to no data on the development of donor-site scars that remain after split skin graft harvesting. The objectives of this study were to (a) examine changes in characteristics of donor-site scar quality over time and (b) assess the agreement between patient-reported and observer-reported donor-site scar quality in a burn population. A prospective cohort study was conducted including patients who underwent split skin grafting for their burn injury. Patients and observers completed the Patient and Observer Scar Assessment Scale (POSAS) for the first harvested donor site at 3 and 12 months post-surgery. This study included 80 patients with a median age of 34 years. At 3 months post-surgery, the patients scored the POSAS items itch and color as most deviant from normal skin, both improved between 3 and 12 months (3.1 vs 1.5 and 5.0 vs 3.5, respectively [P '.001]). Other scar characteristics did not show significant change over time. The patients' overall opinion score improved from 3.9 to 3.2 (P '.001). Observers rated the items vascularization and pigmentation most severe, only vascularization improved significantly between both time points. Their overall opinion score decreased from 2.7 to 2.3 (P '.001). The inter-observer agreement between patients and observers was considered poor (ICC ' 0.4) at both time points. Results of current study indicate that observers underestimate the impact of donor-site scars. This has to be kept in mind while guiding therapy and expectations.
