## TL;DR

This study examines if closed-incision negative-pressure wound therapy helps reduce wound complications in patients with femur bone tumors treated with megaprosthesis.

## Contribution

The study evaluates ciNPWT's effectiveness in minimizing wound complications in megaprosthesis reconstructions after bone tumor resections.

## Key findings

- No significant differences in wound-related complications were found between ciNPWT and conventional dressing groups.
- Wound dehiscence and fluid leakage correlated with surgical site infections and the need for surgical revision.
- ciNPWT appears to help reduce wound dehiscence and leakage despite lack of statistical significance.

## Abstract

Objective
 Surgical management for bone tumors is aggressive in nature and frequently followed by wound-related complications (WRCs). To minimize these events, different strategies have been employed, with closed-incision negative-pressure wound therapy (ciNPWT) emerging as a potential adjuvant. With this study we intend to assess the impact of this technique in minimizing WRCs in patients with proximal and distal femur tumors treated with megaprosthesis.

Methods
 This was an observational retrospective study including 41 participants diagnosed with proximal or distal femur tumors treated with wide resection and reconstruction using a megaprosthesis. Patients were divided into two groups based on the postoperative surgical dressing applied: the vacuum-assisted closure group (VAC) received ciNPWT; and the non-VAC group that received conventional dressings. Data regarding postoperative WRCs and other potential variables of interest were recorded. Statistical analysis was carried out using the IBM SPSS Statistics, version 24.0.

Results
There were 20 patients included in the VAC and 21 in the non-VAC group. The majority of patients presented no complications and there were no differences between groups in terms of WRCs, including infection. Nonetheless, wound dehiscence and persistent fluid leakage had a positive correlation with the diagnosis of infection, which all together presented correlation with the need for surgical revision.

Conclusion
 Despite the absence of statistical significance, ciNPWT seems to help minimize wound dehiscence, persistent wound leakage and surgical site infections in patients with proximal and distal femur bone tumors treated with megaprosthesis. Also, wound dehiscence and persistent wound leakage correlate well with surgical site infection, and those three parameters correlate with the need for surgical revision.

Objetivo
 O tratamento cirúrgico de tumores ósseos é agressivo por natureza e frequentemente seguido por complicações relacionadas com a ferida (CRFs). Para minimizar esses eventos, diferentes estratégias foram empregadas e o penso de pressão negativa (
closed-incision negative-pressure wound therapy
, ciNPWT, em inglês) emergiu como possível adjuvante. Neste estudo, pretendemos avaliar o impacto dessa técnica na minimização de CRFs em pacientes com tumores de fêmur proximal e distal tratados com megapróteses.

Métodos
 Este estudo retrospectivo observacional incluiu 41 participantes diagnosticados com tumores de fêmur proximal ou distal tratados com ressecção alargada e reconstrução com megaprótese. Os pacientes foram divididos em dois grupos com base no penso cirúrgico pós-operatório aplicado: grupo de encerramento assistido por vácuo (
vacuum-assisted closure
, VAC, em inglês), onde foi aplicado ciNPWT; e grupo não-VAC, que recebeu pensos convencionais. Dados sobre CRFs pós-operatórias e outras possíveis variáveis de interesse foram registados. A análise estatística foi realizada recorrendo ao programa IBM SPSS Statistics, versão 24.0.

Resultados
Foram 20 pacientes incluídos no grupo VAC e 21 no grupo não-VAC. A maioria dos pacientes não apresentou complicações e não houve diferenças entre os grupos em termos de CRFs, incluindo infecção. No entanto, deiscência da ferida e extravasamento persistente de fluido tiveram correlação positiva com o diagnóstico de infecção que, juntos, apresentaram correlação com a necessidade de revisão cirúrgica.

Conclusão
 Apesar da ausência de significância estatística, a ciNPWT parece ajudar a minimizar a deiscência da ferida, o extravasamento persistente da ferida e as infecções da ferida operatória em pacientes com tumores ósseos do fêmur proximal e distal tratados com megaprótese. Além disso, a deiscência da ferida e o extravasamento persistente da ferida foram bem correlacionados com a infecção de ferida operatória, e os três parâmetros estão correlacionados com a necessidade de revisão cirúrgica.
