A Prospective, Interventional, Comparative Study to Evaluate the Efficacy of Using Combined Platelet-Rich Plasma and Platelet-Rich Fibrin Over Standard Cleaning and Dressing in Chronic Wounds.

Chronic wounds are defined as wounds that have failed to proceed through the orderly process that produces satisfactory anatomic and functional integrity or that have proceeded through the repair process without producing an adequate anatomic and functional result. The majority of wounds that have not healed in three months are considered chronic, although a duration as low as four weeks has been used to indicate chronicity.Our study aimed to compare the efficacy of autologous platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) versus standard cleaning and dressing as a regenerative medicine strategy to promote healing in chronic wounds. A prospective randomized controlled trial was undertaken to test the efficacy of autologous PRPand PRFin the healing of chronic wounds. A series of 60 cases was compiled from patients attending the outpatient department regularly for the management of chronic wounds. A total of 30 cases were randomly chosen for study with autologous PRP and PRF and 30 cases received conventional dressing. The average healing duration in the study was significantly shorter for the PRP & PRF group. The mean healing time for this group was 4.45 weeks (31.2 ± 3.07 days) compared to 9.61 weeks (67.27 ± 9.19 days) for the conventional dressing group. PRP and PRF belong to a new generation of platelet concentrates that help efficaciously for enhanced healing and functional recovery, safely and cost-effectively. They help by shortening the recovery period overall, improving the quality of life of patients, and altogether eliminating the additional morbidity of operative procedures.

Polyvinyl alcohol-chitosan-polyethylene glycol-glycerol incorporated with Peganum harmala loaded in lipid nanocapsules as an elastic nanocomposite surgical sealant to control bleeding

Uncontrolled hemorrhage remains a critical threat in trauma and surgery. This study developed a novel hemostatic composite by encapsulating Peganum harmala L. seed extract (PH) with known hemostatic properties into lipid nanocapsules (PH-LNCs) and then embedding them within a polyvinyl alcohol-chitosan-polyethylene glycol-glycerol (PVA-CS-PEG-G) matrix. The composite was physically crosslinked via the dual processes of freezing-thawing and thermal crosslinking and exhibited robust mechanical properties reaching 0.434 ± 0.014 MPa and elasticity of 40.685 % ± 4.04. It also demonstrated excellent biocompatibility, surface morphology, physical stability, and ex-vivo skin deposition/permeation were assessed. The characterization of PH-LNCs revealed optimal PH-LNC formation and successful integration into the composite with particle size, zeta potential, and PDI were approximately 45.45 ± 24 nm, −16.3 ± 1.4 mV, and 0.374 ± 0.1, respectively. In vitro studies highlighted enhanced blood clotting and platelet adhesion, while in vivo experiments confirmed superior hemostatic efficacy in a mouse tail amputation model. The composite's soft texture, conformability, and mechanical strength make it a promising candidate for effective traumatic wound management.

The role of computed tomography angiography and digital subtraction angiography in the diagnosis and management of gunshot wounds to the head

Introduction: Traumatic intracranial pseudoaneurysms (TICAs) and penetrating cerebrovascular injuries (PCVI) complicate gunshot wounds to the head (GSWH) and other forms of penetrating traumatic brain injury (pTBI). Recent developments in neuroimaging have allowed early detection of these lesions in the minutes and hours following the initial injury. CT angiography (CTA) and digitally subtracted angiography (DSA) have different sensitivity, periprocedural risks, and logistical limitations. Growing evidence is defining their role in clinical practice. Methods: A systematic review of the literature was performed for published articles treating the use of CTA and DSA to diagnose PCVI and TICAs after pTBI and GSWH. Four series, three retrospective and one prospective, were selected for this review. Results: In three retrospective and one prospective series (with a sensitivity of ~70% in the former studies vs 36% in the latter), DSA emerges as the modality of choice to study the intracranial vasculature of patients that suffered pTBI. Nonetheless, the use of CTA in the first hours after the injury can provide a wealth of information in emergent scenarios where TICAs and PCVIs can significantly affect surgical management and risk. Further, a significantly higher incidence of TICAs was reported in the first hours after civilian GSWH via CTA. Conclusions: DSA and CTA emerged as two complementary techniques in the study and management of PCVI and TICA related to pTBI and GSWH. Their integration can provide a safe approach to the emergent surgical management of vascular lesions via CTA, allowing for delayed DSA characterization after neurological and hemodynamical stabilization.

Open management of rectal wound after transanal endoscopic microsurgery: randomized prospective study

INTRODUCTION: the wound following Transanal Endoscopic Microsurgery (TEM) is traditionally closed by suturing. However, some studies suggest that leaving the wound open after TEM might be a viable alternative. STUDY OBJECTIVE: to compare two methods of managing rectal wounds in patients after TEM. PATIENTS AND METHODS: patients were divided into 2 groups: the main group (open wound management) and the control group (suture wound management). The primary endpoint of the study was the morbidity rate. The secondary endpoints included the need and duration of antibacterial therapy, post-op hospital stay, the severity of the inflammatory response, the wound healing time and the quality of life. RESULTS: from November 2021 to November 2023, 177 patients were included in the randomized study: 68 in the open wound management group and 109 in the suture wound group. The analysis included 50 patients in eachgroup. It was found that the operation time in the main group was significantly shorter (30 (20; 40) minutes versus 55 (40; 60), p < 0.0001). The infectious complications rate was lower in the open wound management group: 11/50 (22 %) versus 16/50 (32 %), p = 0.26; the postoperative bleeding rate was higher: 4/50 (8 %) versus 2/50 (4 %), p = 0.7. Post-op hospital stay did not differ: 6 (4;7) days versus 6 (5; 7), p = 0.22. The duration of antibiotic therapy for infectious complications was longer in the open wound management group: 6 (5;6) days versus 5 (5;6.5), p = 0.02. In the case of infectious complication the inflammatory response was higher in the group of the open wound management: white blood cell counts (15.9 (14.3; 19.5) × 109/L versus 13.1 (12; 15.6) × 109/L, p = 0.01) and temperature (38.6 ± 0.7 °C versus 38 ± 0.6 °C, p = 0.02). Wounds in both groups healed by the 30th day, and the quality of life did not differ between groups. CONCLUSION: the results of the randomized study demonstrated the efficacy and safety of open rectal wound management after TEM.

Investigating the Influence of Natural Compounds on the Healing Process of Wounds

Advancements in modern medicine have not fully resolved the complexities associated with wound healing, particularly for chronic wounds, such as diabetic ulcers and burn injuries. Effective wound management necessitates not only the regeneration of damaged tissue but also minimizing scar formation. In this context, natural compounds derived from plants have emerged as promising candidates for enhancing wound healing. Ethnobotanical research has demonstrated that various herbal extracts possess properties that could significantly improve wound healing outcomes. This review explores the potential of these natural compounds, focusing on their mechanisms of action, efficacy in clinical and preclinical studies, and the challenges that still need to be addressed. By synthesizing findings from traditional medicinal practices and contemporary scientific research, this review aims to provide a comprehensive understanding of how natural compounds can contribute to more effective wound healing strategies. In this review, widely used and studied plants are discussed, along with their ability to induce wound healing through all the phase and their mechanism of action.

Flexible, Electrochemical Skin-Like Platform for Inflammatory Biomarker Monitoring.

Addressing global challenges in wound management has greatly encouraged the emergence of home diagnosis and monitoring devices. This technological shift has accelerated the development of new skin patch sensors for continuous health monitoring. A key requirement is the creation of flexible platforms capable of mimicking human skin features. Here, for the first time, an innovative, highly adaptable electrochemical biosensor with molecularly imprinted polymers (MIPs) is customized for the detection of the inflammatory biomarker interleukin-6 (IL-6). The 3-electrode gold pattern is geometrically standardized onto a 6µm thick polyimide flexible membrane, an optically transparent, and biocompatible polymeric substrate. Subsequently, a biomimetic sensing layer specifically designed for the detection of IL-6 target is produced on these transducers. The obtained MIP biosensor shows a good linear response within the concentration range 50pgmL-1-50ngmL-1, with a low limit of detection (8pgmL-1). X-ray photoelectron spectroscopy, scanning electron microscopy, and Fourier transform infrared spectroscopy characterizations confirm the modifications of the flexible gold transducer. After optimization, the biosensing device shows remarkable potential in terms of sensitivity, selectivity, and reproducibility. Overall, the integration of a low-cost electrochemical sensor on biocompatible flexible polymers opens the way for a new generation of monitoring tools with higher accuracy, less invasiveness, and greater patient comfort.

A dual-layer nano dressing with enhanced antimicrobial and healing properties via sesame nanoemulgel with efficient levofloxacin delivery for wound management

Creating suitable wound dressings is considered a promising approach for treating severe skin injuries, as they can provide the environment for healing and protection against infection. The optimum wound dressing should possess biocompatibility, high absorbency, antimicrobial activity, breathability, and mechanical strength. So, in this study, we created a two-layer dressing that includes a surface layer composed of xanthan, polyvinyl alcohol, and sesame oil, as well as a nanofibrous sublayer that contains polyvinyl alcohol, collagen, levofloxacin, and sesame oil nanoemulsion (Video 1). This dual structure is designed to offer antimicrobial properties and facilitate wound healing while having suitable physical stability. The films showed desirable morphological features and significantly increased flexibility (less than 1000). These features were respectively proven through scanning electron microscopy and tensile strength. Laboratory investigations were conducted to examine the precise compatibility and anti-inflammatory features. According to the obtained results, the nanosystems showed compatibility with hemolysis below 5 percent and by adding sesame oil to the films, their anti-inflammatory properties (88 ± 0.19 %) and blood compatibility (1.3507 ± 0.20) increased. In-vivo studies using the rat skin defect model showed that the dressings significantly accelerate the closure of skin wounds and enhance the reconstruction of skin appendage structures. The therapeutic effect resulted from reducing inflammatory factors, and the film's antimicrobial properties effectively prevent the growth of harmful microorganisms. In conclusion, the study suggests that the new nano-biocomposite films suit wound management.

Fighting A New Front On An Old Battlefield: Examining the Development of Topical Antimicrobial Care to Control Burn Wound Sepsis.

Recognition of invasive burn wound sepsis as a major cause of morbidity and mortality in burn injured patients has profoundly changed the management of burn wounds and its associated complications. The development of effective topical antimicrobial therapy is one of the last major developments of modern burn care and has been driven by major world events and scientific breakthroughs. Topical antimicrobial burn care has evolved from the use of anecdotal remedies to scientific breakthroughs such as Moyer's successful dilution of silver nitrate solution, Fox's described benefit of silver sulfadiazine use in animal models, and Pruitt's dramatic improvement in post-burn mortality using topical mafenide acetate in burn wounds. The objective of this manuscript is to review the definition of burn wound sepsis and highlight the major developments and breakthroughs in topical burn wound care throughout history. This includes historical events like major wars or domestic fires that have influenced or impacted the understanding and treatment of burn wounds. Newer advances in topical antimicrobial care such as nanosilvers and dressing technologies that improve the morbidity and mortality associated with burn wound sepsis and novel approaches to management will also be discussed. To improve burn care, it is prudent to look to the past and learn from the experiences of those who contributed to the control of burn wound sepsis.

Amputação do membro pélvico e reabilitação de equino

Injuries in the locomotor system of equines is a common reality all around the world; however, due the severity of some cases, there is no effective treatment, with euthanasia as the only option. Limb amputation in this species offers an alternative for the recovery and preservation of the animal’s life, which can be a satisfactory result depending on the patient’s temperament and owner’s dedication. This report describes the case of a horse that suffered a total laceration due to an accident with smooth wire, and the tutor opted for amputation of the right pelvic limb instead of euthanasia. Post-operatively, dehiscence of the suture occurred, so the recovery process required continuous monitoring for wound management and correct scar modeling. Rehabilitation included tests with two protheses, which still weren’t properly suited. In the end, the patient adapted to tripedal locomotion and returned to its normal grazing habits after recovery.

SPRR1B+ keratinocytes prime oral mucosa for rapid wound healing via STAT3 activation

Oral mucosal wounds exhibit accelerated healing with reduced scarring compared to cutaneous wounds, representing an optimal wound healing paradigm. However, the specific cellular subtypes orchestrating the efficient healing of mucosal tissues remain elusive. Through a comprehensive analysis integrating bulk-mRNA and single-cell sequencing data during the wound healing process in oral mucosa and skin, we have delineated a distinct set of genes markedly upregulated during tissue repair. This collection of wound healing-associated genesets was highly enriched in a specific keratinocyte subpopulation identified as STAT3-activated SPRR1B+ keratinocytes. Notably, despite the inherent rapidity of oral mucosal healing, the induction of SPRR1B+ keratinocytes is evident in both skin and mucosal wound healing processes in murine model. Intriguingly, these wound healing-promoting SPRR1B+ keratinocytes, which are induced via STAT3 activation, inherently abundant in unwounded normal mucosa but absent in normal skin. SPRR1B knockdown significantly inhibits mucosal keratinocyte migration, a critical attribute for effective wound healing. In summary, through analysis of human oral and skin wound healing processes at single-cell resolution, coupled with validation in murine model, suggests STAT3-activated SPRR1B+ keratinocytes are associated with the rapid mucosal repair process. This discovery underscores the potential application of SPRR1B+ keratinocytes in the therapeutic management of chronic or non-healing wounds.

Silk-enriched hydrogels with ROS-scavenging dendrimers for advanced wound care

This study explores the development of novel hydrogel composites for wound care, incorporating silk fibroin and reactive oxygen species (ROS)-scavenging dendrimers into a polyvinyl alcohol (PVA) matrix. Utilizing ionizing gamma radiation, we fabricated pristine PVA, silk-PVA (SPVA) binary, and dendrimer-silk-PVA (DSPVA) ternary hydrogel composites, with their composition confirmed via UV–visible absorption spectroscopy. Fourier-transform infrared (FTIR) and Raman spectroscopy analyses indicated complex interactions between the hydrogel components, enhancing their structural and biocompatible properties. Scanning electron microscopy (SEM) analysis revealed that dendrimer integration in DSPVA hydrogels significantly increased surface porosity, vital for tissue regeneration. The DSPVA hydrogels demonstrated effective ROS scavenging, reducing hydrogen peroxide (H2O2) concentrations by approximately 70 % within 24 h. In vivo wound healing studies in a diabetic mouse model showed enhanced wound closure in the DSPVA group, with a relative wound area reduction to 30 ± 4.3 % on day 10, compared to 56.5 ± 2.7 % in the control group. By the 16th day, the treated group exhibited near-complete wound contraction, markedly outperforming the control group. These findings underscore the potential of DSPVA hydrogels in diabetic wound management, combining silk fibroin's mechanical support, dendrimers' antioxidative properties, and PVA's structural benefits. Thus, DSPVA hydrogels are promising candidates for advanced wound care applications.

C-di-GMP@ZIF-8 nanocomposite injectable hydrogel based on modified chitosan and hyaluronic acid for infected wound healing by activating STING signaling

The treatment of infected wounds relies on antibiotics; however, increasing drug resistance has made therapeutic processes more difficult. Activating self-innate immune abilities may provide a promising alternative to treat wounds with bacterial infections. In this work, we constructed an immunogenic injectable hydrogel crosslinked by the Schiff base reaction of carboxymethyl chitosan (NOCC) and aldehyde hyaluronic acid (AHA) and encapsulated with stimulator of interferon genes (STING) agonist c-di-GMP loaded ZIF-8 nanoparticles (c-di-GMP@ZIF-8). Nanocubic ZIF-8 was screened as the most efficient intracellular drug delivery vector from five differently-shaped morphologies. The NOCC/AHA hydrogel released c-di-GMP@ZIF-8 more quickly (43 %) in acidic environment (pH = 5.5) of infected wounds compared with 34 % in non-infected wound environment (pH = 7.4) at 96 h due to pH-responsive degradation performance. The released c-di-GMP@ZIF-8 was found to activate the STING signaling of macrophages and enhance the secretion of IFN-β, CCL2, and CXCL12 5.8–7.6 times compared with phosphate buffer saline control, which effectively inhibited S. aureus growth and promoted fibroblast migration. In rat models with infected wounds, the c-di-GMP@ZIF-8 nanocomposite hydrogels improved infected wound healing by promoting granulation tissue regeneration, alleviating S. aureus-induced inflammation, and improving angiogenesis. Altogether, this study demonstrated a feasible strategy using STING-targeted and pH-responsive hydrogels for infected wound management.

Hyaluronic acid methacryloyl/chitosan methacryloyl/3-methacrylamidophenylboronic acid multifunctional hydrogel loading exosome for diabetic wound healing

The management of diabetic wounds presents a formidable challenge in clinical settings due to elevated glucose levels, drug-resistant bacterial infections, and a deficiency of bioactive molecules in the microenvironment. To address this challenge, a glucose-responsive Hyaluronic acid Methacryloyl (HAMA)-Chitosan Methacryloyl (CSMA)-3-Methacrylamidophenylboronic acid (MPBA) loading Exosome (H-C-M@Exo) multifunctional hydrogel has been developed to enhance diabetic wound healing in this study. The H-C-M@Exo hydrogel exhibits remarkable features, including high hydrophilicity, excellent pressure resistance, antibacterial properties, and good biocompatibility. It uniquely possesses the ability to sustain the release of exosomes in response to glucose fluctuations. The H-C-M@Exo hydrogel can effectively reduce inflammation, significantly promote rapid re-epithelization, facilitate favorable collagen deposition, and stimulate abundant angiogenesis at the wound sites. Furthermore, the hydrogel induces localized regulation of M2 macrophage polarization, synergistically promoting diabetic angiogenesis and wound healing. These findings suggest H-C-M@Exo hydrogel is a promising biomaterial for the treatment of chronic diabetic wounds.

Identification of High-Risk Lower Extremity Wounds Using Point-of-Care Test for Bacterial Protease Activity; A Single-Centre, Single-Blinded, Prospective Study.

Clinician observation is the mainstay to determine if wound infection is present, and focuses on presence of erythema, purulence, and odour. However, non-visible bacterial protease activity can delay wound healing and lead to complications. In this study, a point-of-care test to detect the presence of bacterial protease activity (BPA, tested with Woundchek Bacterial Status test) was appraised. A total of 130 patients with lower extremity wounds were recruited in vascular and podiatry clinics, and across two time-points 182 BPA tests were conducted subsequent to initial (blinded) clinician's wound appraisal. Clinical opinion ('no infection', 'possible' or 'definite' infection) and BPA result (negative or positive test) had a moderate Kendall's tau-c rank correlation coefficient of 0.32 (P < 0.001). Binary logistic regression analysis and principal component analysis showed that infection determined by clinical opinion was significantly associated with abovementioned clinical signs and a positive BPA test. However, a positive BPA result was also significantly linked with wound severity, such as number of lesions, chronicity and size. Throughout a 12-week follow-up period, median ulcer size was larger for wounds positive for BPA test at baseline (P 0.001) and week-12 (P 0.036; both Mann-Whitney U-test) respectively. As a pilot initiative, clinical staff were allowed to act on the BPA result if they wished; in 11 out of 71 test-positive cases (15%) this happened and antimicrobial dressing was applied instead of planned standard dressing. These results show that protease-releasing bacteria may be active in ulcers that do not (yet) exhibit hallmark signs of infection, and are associated with delayed healing. Targeted point-of-care testing for bacterial protease activity may have the potential to identify and enable pro-active (antimicrobial) management of these high-risk wounds.

3D Bilayered Hydrogel and Nanofiber Multifunctional Sponge Dressing: An Efficacious Healing Agent for Chronic Wound Healing.

Chronic wound management using biomaterial-based dressings has significantly impacted the standard and efficiency of wound healing. However, various available wound healing aids are ineffective in treating deep open injuries and chronic wounds such as diabetic wounds. Herein, we developed a 3D bilayered multifunctional sponge, which addresses the structural and functional issues faced by biomaterial dressings in treating deep and chronic wounds. The 3D bilayered sponge consists of a hydrogel base functionalized with wound healing peptide (Tylotoin)-carrying nanoparticles and topped with a nanofiber layer functionalized with an antimicrobial peptide (LLKKK18). The 3D bilayered sponge, with its highly porous, elastic, and enhanced fluid absorption ability, makes it a suitable wound treatment aid. The developed multifunctional 3D sponge shows antibacterial action and promotes a microenvironment similar to the extracellular matrix (ECM) in regulating dermal cell survival and migration. Study in a full-thickness skin defect diabetic mouse model has shown that the developed 3D bilayered sponge accelerated wound closure and promoted functional skin regeneration through reduced inflammation, faster granulation tissue formation, re-epithelialization, neovascularization, and skin appendage restoration, which make the developed 3D bilayered multifunctional sponge an efficient and advanced chronic wound management aid with potential for future clinical application.

Early experience using vacuum-assisted closure for managing soft tissue injuries in open type IIIB tibial fractures, a non-randomised controlled trial from a North African level one trauma centre

Purpose: The primary objective was to investigate our early results of using vacuum-assisted closure (VAC) for wound management in patients with open IIIB tibial fractures and compare the results with a group subjected to conventional daily dressing. Methods: A prospective non-randomised clinical trial (NRCT) with a parallel design and allocation ratio of 1:1 was conducted after obtaining ethical committee approval. Forty skeletally mature patients with unilateral type IIIB open tibia fractures were included over two years, starting from April 2019. In group A, patients were treated with VAC, which was changed every four days if needed, and in group B, patients had daily conventional dressings. Results: Both groups had no differences in the basic demographic, comorbidities, injury mechanism, and associated injuries. The need for secondary debridement surgeries was significantly lower in Group A than in Group B, 1 ± 0.50 versus 2.50 ± 0.85, respectively ( P &lt; 0.001). The time till definitive coverage was significantly lower in Group A than in Group B, 12.22 ± 2.90 versus 23.56 ± 8.68 (days); P &lt; 0.001. All coverage procedures succeeded in Group A, while four (20%) failed in Group B, P = 0.04. Infection was higher in Group B, with six (30%) patients compared to one (5%) in Group A, P = 0.01. Conclusion: Reports on VAC's role in managing severe open fracture wounds are rare in our area, and the initial results we obtained are encouraging, with lower infection rates and less cumbersome reconstruction procedures; however, further evaluation of the procedure's cost-effectiveness is mandatory.

Development and Preliminary Validation of a Central Venous Access Device-Associated Skin Impairment Classification Tool Using Modified Delphi and Clinimetric Methods.

An evidence and consensus-based instrument is needed to classify central venous access device-associated skin impairments. The aim of this study was to design and evaluate the central venous access device-associated skin impairment classification tool. A two-phase modified Delphi study. This two-phase study consisted of a literature review, followed by the development and validation of a classification instrument, by experts in the fields of central venous access devices and wound management (Phase 1). The instrument was tested (Phase 2) using 38 clinical photographs of a range of relevant skin impairments by the same expert panel. The expert panel consisted of registered nurses who were clinical researchers (n = 4) and clinical experts (n = 3) with an average of 24 years of nursing and research experience and 11 years of experience in wound management. Measures to assess preliminary content validity and inter-rater reliability were used. The instrument consists of five overarching aetiological classifications, including contact dermatitis, mechanical injury, infection, pressure injury and complex clinical presentation, with 14 associated subcategory diagnoses (e.g., allergic dermatitis, skin tear and local infection), with definitions and signs and symptoms. High agreement was achieved for preliminary scale content validity and item content validity (I-CVI = 1). Inter-rater reliability of aetiologies was high. The overall inter-rater reliability of individual definitions and signs and symptoms had excellent agreement. The development and preliminary validation of this classification tool provide a common language to guide the classification and assessment of central venous access device-associated skin impairment. The comprehensive and validated classification tool will promote accurate identification of central venous access device-associated skin impairment by establishing a common language for healthcare providers. The availability of this tool can reduce clinical uncertainty, instances of misdiagnosis and the potential for mismanagement. Consequently, it will play a pivotal role in guiding clinical decision-making, ultimately enhancing the quality of treatment and improving patient outcomes. The Guidance on Conducting and Reporting Delphi Studies (CREDES) was adhered to. No patient or public contribution.

Pressure makes diamonds? The impact of closed incision negative pressure wound therapy on complications following abdominoplasty in patients with massive weight loss—results from a case controlled trial

BackgroundThe effectiveness of closed incision negative pressure wound therapy (ciNPWT) has been shown across various studies. However, studies with large patient cohorts comprising post-bariatric patient populations are missing. The objective of this research was to assess the influence of ciNPWT on post-operative wound complications in this demanding patient collective. MethodsWe conducted a retrospective case-control study. Between 1 January 2013 and 31 December 2023, a total of 251 abdominoplasty procedures following massive weight loss were identified. Patients were matched based on resection weights. We matched 118 patients separated into two groups depending on post-surgical wound management (conventional wound dressings vs ciNPWT). The primary outcomes were wound-related disorders and secondary outcomes were the number of readmissions or reoperations within 30 days after the initial surgery. ResultsThe study revealed equal incidence of seroma formation (15 vs 15, p = 1.0), rates of wound dehiscence (23 vs 20, p = 0.56), surgical site infection (11 vs 6, p = 0.18), hematoma (17 vs 9, p = 0.07), complete removal of all drainages (6.7 vs 6.1 days, p = 0.34) and total number of readmission (12 vs 11, p = 0.77) or reoperations (12 vs 10, p = 0.63) within 30 days. The second hospital stay caused by revision was significantly shorter in the ciNPWT group (5.8 days vs 12.0 days, p = 0.02). ConclusionConsequently, we did not find evidence to support the hypothesis that ciNPWT reduces complications after abdominoplasty in patients with massive weight loss.
