Negative pressure wound therapy in pediatric surgery: How and when to use

Use of Vacuum-Assisted Closure to Reduce the Likelihood of Wound Complications After Limb-Sparing Resection of Pediatric Primary Bone Sarcomas of the Femur

BACKGROUND

Limb-sparing surgery is the standard of care for primary bone tumors. However, such procedures are associated with high rates of wound complications, specifically in lower-extremity surgeries. Therefore, identifying and implementing interventions to minimize the likelihood of wound complications after limb-sparing resection of the lower extremity is crucial.

METHODS

Patients who underwent limb-sparing osteosarcoma or Ewing sarcoma resection during a 7-year period at a single institution were retrospectively reviewed. Data were collected on 39 patients who underwent limb-sparing resection of the femur. Patient demographics, tumor characteristics, and perioperative and postoperative data were extracted and analyzed. Patients who underwent resection before April 2017 received conventional postoperative incision dressings. Starting in April 2017, patients received vacuum-assisted closure (VAC) with the 3 M™ Prevena VAC system after surgical closure. Eighteen patients received conventional postoperative incision dressing, and 21 received incisional wound VAC. A wound complication was defined as any Clavien-Dindo classification greater than 0 within a 28-day postoperative period.

RESULTS

Patients who received postoperative incisional wound VAC had lower rates of wound complications than those who received conventional incision dressings (14% vs. 50%; p = 0.035). Additionally, patients in whom wound complications developed had a longer average hospital stay than those without wound complications (5 days vs. 4 days; p = 0.029).

CONCLUSIONS

Wound complications prolong the hospital stay and can delay adjuvant chemotherapy for bone tumors. The use of postoperative incisional wound VAC is associated with less likelihood of wound complications and should be considered in any high-risk surgical closure.

Negative pressure wound therapy for extensive soft tissue defects of the lower extremity in a teenager: A case study

Key Clinical Message

Negative pressure wound therapy (NPWT) aided in the management of complex soft tissue injury in a 14-year-old girl by managing moisture, reducing oedema, and stimulating wound granulation less than 2 months after the accident and prepared the skin for skin grafting, thus successfully saving the limb.

Abstract

This case study describes the use of a tubular bandage encompassing the whole limb to deliver successful NPWT in the treatment and reconstruction of extensive soft tissue damage extending from the right lower extremity to the hip in a 14-year-old female.

Chinese expert consensus on the Management of Pediatric Deep Partial-Thickness Burn Wounds (2023 edition)

Burns are a main cause of accidental injuries among children in China. Because of the unique wound repair capacity and demand for growth in pediatric patients, the management of pediatric deep partial-thickness burn wounds involves a broader range of treatment options and controversy. We assembled experts from relevant fields in China to reach a consensus on the key points of thermal-induced pediatric deep partial-thickness burn-wound management, including definition and diagnosis, surgical treatments, nonsurgical treatment, choice of wound dressings, growth factor applications, infectious wound treatment, scar prevention and treatment. The committee members hope that the Expert Consensus will provide help and guiding recommendations for the treatment of pediatric deep partial-thickness burn wounds.

Roles of negative pressure wound therapy for scar revision

The purpose of this study is to review the research progress of negative pressure wound therapy (NPWT) for scar revision and discuss the prospects of its further study and application. The domestic and foreign literatures on NPWT for scar revision were reviewed. The mechanism and application were summarized. NPWT improves microcirculation and lymphatic flow and stimulates the growth of granulation tissues in addition to draining secretions and necrotic tissue. As a significant clinical therapy in scar revision, NPWT reduces tension, fixes graft, and improves wound bed. In the field of scar revision, NPWT has been increasingly used as an innovative and constantly improving technology.

Primary and secondary vaginal reconstruction with autologous buccal mucosa and intravaginal wound vacuum therapy

BACKGROUND

Vaginal reconstruction with autologous buccal mucosa graft offers a promising alternative to the use of skin grafts and vascularized intestinal segments. Given the novelty of this procedure, the optimal approach to postoperative wound management remains unclear with current practices often requiring many months of vaginal stents/molds. This study aims to evaluate a newly developed negative pressure intravaginal wound vacuum placed at the conclusion of the vaginoplasty with the goals of facilitating graft take and healing.

METHODS

A retrospective review of patients (age 12-21 years) who underwent eight primary and secondary vaginoplasty procedures using autologous buccal mucosa coupled with intravaginal wound vacuum placement was performed.

RESULTS

Vaginal reconstruction with fenestrated full-thickness buccal mucosa graft and intravaginal wound vacuum placement was successfully performed eight times in seven patients at a median age of 15.6 years. Four patients underwent robotic vaginal pull-through with buccal mucosa serving as an interposition graft, and four patients underwent vaginoplasty with buccal graft alone. All cases had excellent engraftment at time of wound vacuum removal on postoperative day seven and had healthy-appearing buccal mucosa at a mean follow-up of 148 days. Postoperatively, one patient developed a stricture at the anastomosis between native vagina and buccal mucosa graft, requiring a second buccal mucosa graft six months after the first operation.

CONCLUSIONS

The use of autologous buccal mucosa graft for primary and secondary vaginal reconstruction coupled with intravaginal wound vacuum therapy offers a promising new approach. Negative pressure wound vacuum therapy may provide a more optimal wound healing environment for improved outcomes.

Treatment options for soft tissue defects in severe foot trauma in children

OBJECTIVE

Severe foot trauma in children is a therapeutic challenge, with presence of devitalised and soiled distal tissues. Several reconstruction and covering procedures can be applied, including artificial dermis (AD), negative pressure wound therapy (NPWT), fasciocutaneous flaps and free flaps. Here, we have developed and evaluated an algorithm for treating severe foot injuries with skin defects in children.

METHOD

Paediatric cases of severe foot injury treated over a 16-year period were retrospectively reviewed. Characteristics of the injuries, surgical procedures, complications and the modified Kitaoka score (clinical and functional rating score of the ankle and foot) were recorded.

RESULTS

A total of 18 children were included. The mean age at the time of injury was four years and 10 months (range: 1-11 years). The mean follow-up period was 6.2 years. Of the children, 13 presented with an amputation (12 partial foot amputations and one whole ankle and foot). The skin defect was combined with tendon exposure in nine cases, and/or bone and cartilage in seven cases, and heel damage in two cases. A flap was implemented in eight cases, of which one failed. NPWT was used in 13 patients (for an average of 21 days) and was combined with AD in six patients. The mean modified Kitaoka score was 68 (range: 55-80). Additional surgery during the follow-up period was required in seven patients (dorsal skin retraction, a thick flap, osteoma, trophic ulcer or ankle deviation).

CONCLUSION

Our algorithm suggests different therapeutic strategies for skin coverage and healing, depending on the size of the lesion and the exposed structures, and seems to offer good results. These procedures should be combined with NPWT to optimise these results (improved healing, reduced infections, decreased skin defects and enhanced granulation tissue) and so should be used more frequently.

Negative Pressure Wound Therapy in Pediatric Burn Patients: A Systematic Review

Significance: Negative pressure wound therapy (NPWT) requires the placement of a dressing over a wound, covered with an adhesive film, and applying to these dressing a negative pressure in a controlled fashion. This therapy is a powerful complement to surgical care of wounds. Data are however poor on its use in pediatric burns. Recent Advances: This systematic review, including a total of 466 patients, shows that NPWT as the initial treatment for burned children and after skin grafting has been shown to produce promising results. In the majority of studies, skin graft take rate is close to 100%. This therapy is particularly beneficial in the pediatric population because of less frequent dressing changes and early mobilization. NPWT devices accurately quantify burns water losses and allow tailoring liquid resuscitation. Critical Issues: NPWT is not in the subject of controlled clinical trials in pediatric; most publications are case reports or retrospective reviews. The sporadic complications include bleeding, local infections, and mechanical device issues. Future Directions: NPWT has been used in 2-month up to 18-year-old children with deep second- to third-degree burn of multiple etiologies, from a few days up to several months, on small to 40% total body surface area (%), and in difficult areas. Data gathered provide empirical guidelines on NPWT use in pediatric burns using continuous mode with a pressure of -50 to -75 mmHg for children younger than 2 years, and -75 to -125 mmHg in children over 2 years of age. Prospective randomized studies are needed to provide validated rules.

Vacuum-assisted closure (VAC) prevents wound dehiscence following posterior sagittal anorectoplasty (PSARP): An exploratory case-control study

BACKGROUND

Wound dehiscence (WD) of the anocutaneous anastomosis or perineal body after posterior sagittal anorectoplasty (PSARP) is common. We aimed to evaluate the efficacy of a perineal vacuum-assisted closure (VAC) for prevention of WD following repair of anorectal malformations (ARM) with rectoperineal and rectovestibular fistula.

METHODS

A retrospective dual-center case-control study of children undergoing PSARP without colostomy between 2011 and 2019 was performed. The VAC group received preoperative bowel preparation (PBP), postoperative application of a VAC, loperamide (only Location A), intravenous antibiotics (IA), and total parenteral nutrition (TPN). The non-VAC group underwent PBP, loperamide (Location A), IA, and TPN without VAC. Primary outcome was WD at the anocutaneous anastomosis or reconstructed perineal body within the first 14 days after surgery.

RESULTS

The study population included 18 patients (VAC group) and 20 children (non-VAG group) with rectoperineal and rectovestibular fistula. The incidence of WD in the VAC group was 0% compared to 25% in the non-VAC group (0/18 vs. 5/20, p = 0.04). No VAC related complications occurred.

CONCLUSION

Postoperative application of a VAC embedded in a perioperative treatment protocol has the potential to prevent wound dehiscence of the neoanus and reconstructed perineal body following PSARP.

Complex ventral hernia repair in a child: An association of botulinum toxin, progressive pneumoperitoneum and negative pressure therapy. A case report on an arising surgical technique

•

Giant omphalocele establish a therapeutic challenge to the surgeon - mainly because of the increased visceroabdominal disproportion and underlying malformations - and the best approach is still debatable worldwide.

•

This is the second report on the literature and states the management of a child born with giant omphalocele that developed a very complex ventral hernia secondary to an unsuccessful attempt of closing the primary defect.

•

It seems that the use of botulinum toxin agents in the abdominal wall is safe and effective in children with giant omphaloceles and it eliminates the use of a mesh even in more difficult cases.

•

This technique seems safe and effective and it should be encouraged and best evaluated.

•

It is time to start defining better criteria to categorize giant omphalocele in order to choose the best management for each patient.

Introduction

The purpose of this manuscript is to report the management of a child born with giant omphalocele (GO) that developed a complex ventral hernia secondary to an unsuccessful attempt of closing the primary defect.

Presentation of case

The patient underwent a one-step surgery to correct a ventral hernia associated with a largely prolapsed enteroatmospheric fistula (EAF) along with an ileostomy. It was managed by a pre-operative association of botulinum toxin agent (BTA) application with preoperative progressive pneumoperitoneum (PPP) and trans-operative negative pressure wound therapy (NPWT) dressing with staged abdominal closure. The patient needed 4 reoperations due to enteric fistulas. Nine days after the first surgery, it was possible to completely close the abdominal wall without mesh substitution. No signs of hernia in 9 months of follow-up.

Discussion

This is the second report in the literature and it reinforces the safety and effectiveness of the BTA injection associated with PPP in children.

Conclusion

The use of BTA in association with PPP should be encouraged and best investigated in patients with GO. The fistulas were not attributed to the negative pressure. Maybe it is time to start defining better criteria to categorize GO in order to choose the best management for each patient.

Pediatric necrotizing soft tissue infection after elective surgery: A case report and literature review

INTRODUCTION

Necrotizing soft tissue infections (NSTIs) are rare but often lethal. Early diagnosis and aggressive surgical debridement are essential to achieve the best possible outcome.

CASE PRESENTATION

A 12-year old boy was diagnosed with a necrotizing soft tissue infection following elective revision surgery for functional impairment resulting from scar tissue of the neck. Fever and inflammation of the surgical wound manifested 24-36 hours postoperatively. Antibiotic therapy with amoxicillin-clavulanic acid was initiated, but the patient was unresponsive. Ultrasonography, a wound culture and surgical exploration confirmed the diagnosis. The culture was positive for a Streptococcus pyogenes infection and antibiotic treatment was switched to penicillin and clindamycin. Following the diagnosis, surgical debridement was performed subcutaneously, and only necrotic tissue was removed to preserve as much skin tissue as possible. After eradication of the infection, vacuum-assisted closure of the wound was used to close the subcutaneous space. The patient was discharged after 40 days.

CONCLUSION

In this patient, we treated a necrotizing soft tissue infection with antibiotics, skin sparing surgeries and negative pressure wound therapy (NPWT). We used ultrasonography as imaging technique to help with the diagnosis. The extensiveness of surgical debridement was rather limited. We focused on opening all affected fascial layers. The surgical debridement was subcutaneous, and only necrotic tissue was removed. Because of the location in the neck, we tried to avoid an aggressive skin debridement to preserve as much skin tissue as possible. Negative pressure wound therapy is not frequently used in this context but it contributed to an enhanced wound healing. Ultrasonography for diagnosing NSTIs is useful, but the clinical findings and an explorative surgery will remain most important.

Negative Pressure Wound Therapy in children: A 25 cases series

Negative Pressure Wound Therapy is a device applied to a wound that causes local depression. There are a few series showing the effectiveness of this treatment in Pediatric. The objective of this work is to try to clarify the indications in children. This is a retrospective series of 25 children between 2004 and 2019. The inclusion criteria were all children with a wound treated with Negative Pressure Wound Therapy. The characteristics retained were their age, the context of occurrence, the treatment time, the depression applied, the technique of skin covering wound and the average healing time. We included 25 patients. The average age was 8.8 years. The context of the wound occurrence was mainly a road (44%) or a domestic (36%) accident. Substance losses were mainly located in the lower limb (84%). The depression applied was -90mmHg. The healing time was 18.4 days. Thin skin grafting was the main method chosen (88%). No complications related to Negative Pressure Wound Therapy equipment have been identified. Despite the weakness of the literature and the lack of consensus regarding its use, Negative Pressure Wound Therapy is an essential therapy in pediatric. It is a simple and effective technique in children. It can reduce the need for flaps coverage, even in the event of exposure of noble elements. The flaps should not, however, be excluded from the decision-making algorithm, on pain of complications or sequelae.

Traditional and advanced therapeutic modalities for wounds in the paediatric population: an evidence-based review

OBJECTIVE

Children can have non-healing wounds due to a wide range of pathologies, including epidermolysis bullosa (EB), pilonidal disease and Stevens-Johnson syndrome, with some causes being iatrogenic, including extravasation injuries and medical device-related hospital-acquired pressure ulcers. Furthermore, paediatric wounds are vastly different from adult wounds and therefore require a different treatment approach. While there are numerous types of dressings, topical remedies, and matrices with high-tier evidence to support their use in adults, evidence is scarce in the neonatal and paediatric age groups. The purpose of this review is to discuss the basic principles in paediatric wound management, as well as to present new treatment findings published in the literature to date. The benefits and risks of using different types of debridement are discussed in this review. Various topical formulations are also described, including the need to use antibiotics judiciously.

METHOD

Databases were searched for relevant sources including Pubmed, Embase, Web of Science and DynaMed. Search terms used included 'wound care', 'wound management', 'paediatrics', 'children', 'skin substitutes', and 'grafts'. Additionally, each treatment and disease entity was searched for relevant sources, including, for example: 'Apligraf', 'dermagraft', 'Manuka honey', 'antibiotic', 'timolol', and 'negative pressure wound therapy' (NPWT).

RESULTS

Amniotic membrane living skin equivalent is a cellular matrix that has been reportedly successful in treating paediatrics wounds and is currently under investigation in randomised clinical trials. Helicoll is an acellular matrix, which shows promise in children with recessive dystrophic EB. NPWT may be used as a tool to accelerate wound closure in children; however, caution must be taken due to limited evidence to support its safety and efficacy in the paediatric patient population. Integra has been reported as a useful adjunctive treatment to NPWT as both may act synergistically. Hospitalised children and neonates frequently have pressure ulcers, which is why prevention in this type of wound is paramount.

CONCLUSION

Advancements in wound care are rapidly expanding. Various treatments for non-healing wounds in paediatric and neonatal patients have been reported, but high tier evidence in these populations is scarce. We hope to shed light on existing evidence regarding the different therapeutic modalities, from debridement techniques and dressing types to tissue substitutes and topical remedies. There have been promising results in many studies to date, but RCTs involving larger sample sizes are necessary, in order to determine the specific role these innovative agents play in paediatric wounds and to identify true safety and efficacy.

Inpatient Versus Outpatient Management of Negative Pressure Wound Therapy in Pediatric Patients

BACKGROUND

Negative pressure wound therapy (NPWT) is commonly used to manage complex wounds in the pediatric population. With recently developed portable NPWT devices, providers have the opportunity to transition NPWT to the outpatient setting. However, there are no studies describing outpatient NPWT in pediatric patients. Therefore, the purpose of our study was to leverage a population-level analysis to advance our current knowledge about outpatient NPWT use in pediatric patients.

MATERIALS AND METHODS

We analyzed the Truven Health Analytics MarketScan Commercial Claims Database from 2006 to 2014 to identify children treated with NPWT. We compared patient characteristics, indications, complications before and after NPWT, health care utilization within 30 d of NPWT initiation, and health care cost profile of patients treated with NPWT primarily as outpatients versus inpatients. Outpatient NPWT was defined as patients with ≤50% of NPWT coded during an inpatient hospitalization, whereas inpatient NPWT was defined as patients with >50% of NPWT.

RESULTS

We identified 3184 patients (1621 inpatients and 1563 outpatients) aged 0-17 y, who were treated with NPWT from 2006 to 2014. Outpatient NPWT was implemented across multiple ages, comorbidities, and indications, with a low complication rate (2.4%). After controlling for hematologic comorbidity and indications, outpatient NPWT was associated with lower risk of complications (odds ratio: 0.57, 95% confidence interval 0.38-0.86) and lower median total costs ($5602.03) compared with inpatient ($15,233.21) therapy.

CONCLUSIONS

Outpatient NPWT management in pediatric patients was associated with low complication rates. Additional studies are necessary to determine the most overall cost-effective treatment setting for NPWT in the pediatric population.

Surgical Management of Pediatric Hidradenitis Suppurativa: A Case Series and Review of the Literature

BACKGROUND

Hidradenitis suppurativa (HS) is a chronic and physically debilitating condition. Achieving long-term remission is difficult and sometimes remains elusive despite use of multiple pharmacological agents. However, surgery remains underused in the pediatric population.

METHODS

We conducted a retrospective review for a 10-year period of all patients younger than 18 years who had undergone surgery for HS at a tertiary university hospital. In addition, we performed a literature review for English language articles related to the surgical management of pediatric HS patients.

RESULTS

Eleven patients with a total of 23 operative sites were included in the study. The cohort was predominantly female (10:1) with an average age of 15.4 years and mean body mass index 31.9 kg/m. Lesion size ranged from 12.6 to 400 cm. Overall complication rate was 87% with a 7% reoperation rate to manage complications. Remission was achieved after a single procedure in 57% of sites. Three articles met our inclusion criteria for the literature review.

CONCLUSIONS

Our article adds to the sparse literature and represents the largest study on surgical management of pediatric HS patients. Although surgery is not without its challenges, it presents a safe option and for pediatric HS patients with extensive scar or sinus tract formation.

Microdeformational wound therapy: A novel option to salvage complex wounds associated with the Nuss procedure

BACKGROUND

Complex wounds associated with the Nuss procedure are a resource intensive complication that may lead to significant morbidity with potential removal of the implanted device and abandonment of the repair. We report our management technique of this complication utilizing microdeformational wound therapy (MDWT) that is safe, is efficacious and allows for salvage of the repair.

OPERATIVE TECHNIQUE

We defined a complex wound as a wound that became suppurative and drained in the postoperative period and failed to resolve with a trial of conventional wound management and antibiotics. Upon recognition of a complex wound, we recommend an initial operative wound debridement. This allows wound cultures, wound assessment and precise initiation of MDWT. It is not uncommon to have exposed hardware in the wound early in the course of therapy. Metal allergy must be excluded. The patient is transitioned to oral antibiotics following resolution of the acute process. MDWT is performed until the wounds are completely epithelialized with no clinical signs of drainage or infection. The average length of MDWT in our patients was 39 days. Following complete wound healing the patients are maintained on antibiotics until implant removal.

CONCLUSIONS

The use of microdeformational wound therapy in complex wounds associated with the Nuss procedure is a safe and effective modality. The technique may reduce the likelihood of implant removal with potential recurrent pectus excavatum.

TYPE OF STUDY

Operative technique.

Negative pressure wound treatment with computer-controlled irrigation/instillation decreases bacterial load in contaminated wounds and facilitates wound closure

Microbial wound contamination is known to be a hindrance to wound healing. Negative pressure wound therapy (NPWT) with or without irrigation is known to optimise conditions in problem wounds. The aim of this study was to investigate the influence of computer-controlled wound irrigation with NPWT on the bacterial load in contaminated wounds. A total of 267 patients were treated with NPWT with automated instillation because of problematic wounds using an antiseptic instillation solution. In 111 patients, a minimum of 4 operative procedures were necessary, and swabs were taken at least at the first and at the fourth operation in a standardised procedure. The number of different bacteria and the amount of bacteria were analysed during the course. In a subgroup of 51 patients, swabs were taken at all 4 operative procedures and analysed separately. In an overall analysis, the number of different bacteria and the amount of bacteria significantly decreased independent of wound localisation and diagnosis. NPWT with automated instillation demonstrates a positive influence in the reduction of bacterial load in problem wounds. Thus, it may help to optimise wound conditions before definite wound closure.
