Double-nylon purse-string suture in closing postoperative wounds following endoscopic resection of large(≥3 cm)gastric submucosal tumors

BACKGROUND Endoscopic full-thickness resection(EFTR)of gastric submucosal tumors(SMTs)is safe and effective;however,postoperative wound management is equally important.Literature on suturing following EFTR for large(≥3 cm)SMTs is scarce and limited.AIM To evaluate the efficacy and clinical value of double-nylon purse-string suture in closing postoperative wounds following EFTR of large(≥3 cm)SMTs.METHODS We retrospectively analyzed the data of 85 patients with gastric SMTs in the fundus of the stomach or in the lesser curvature of the gastric body whose wounds were treated with double-nylon purse-string sutures after successful tumor resection at the Endoscopy Center of Renmin Hospital of Wuhan University.The operative,postoperative,and follow-up conditions of the patients were evaluated.RESULTS All tumors were completely resected using EFTR.36(42.35%)patients had tumors located in the fundus of the stomach,and 49(57.65%)had tumors located in the body of the stomach.All patients underwent suturing with double-nylon sutures after EFTR without laparoscopic assistance or further surgical treatment.Postoperative fever and stomach pain were reported in 13(15.29%)and 14(16.47%)patients,respectively.No serious adverse events occurred during the intraoperative or postoperative periods.A postoperative review of all patients revealed no residual or recurrent lesions.CONCLUSION Double-nylon purse-string sutures can be used to successfully close wounds that cannot be completely closed with a single nylon suture,especially for large(≥3 cm)EFTR wounds in SMTs.

The Application of Bilayer Artificial Dermis Combined with VSD Technology in Chronic Wounds

Background: Bilayer artificial dermis promotes wound healing and offers a treatment option for chronic wounds. Aim: Examine the clinical efficacy of bilayer artificial dermis combined with Vacuum Sealing Drainage (VSD) technology in the treatment of chronic wounds. Method: From June 2021 to December 2023, our hospital treated 24 patients with chronic skin tissue wounds on their limbs using a novel tissue engineering product, the bilayer artificial dermis, in combination with VSD technology to repair the wounds. The bilayer artificial dermis protects subcutaneous tissue, blood vessels, nerves, muscles, and tendons, and also promotes the growth of granulation tissue and blood vessels to aid in wound healing when used in conjunction with VSD technology for wound dressing changes in chronic wounds. Results: In this study, 24 cases of chronic wounds with exposed bone or tendon larger than 1.0 cm2 were treated with a bilayer artificial skin combined with VSD dressing after wound debridement. The wounds were not suitable for immediate skin grafting. At 2 - 3 weeks post-treatment, good granulation tissue growth was observed. Subsequent procedures included thick skin grafting or wound dressing changes until complete wound healing. Patients were followed up on average for 3 months (range: 1 - 12 months) post-surgery. Comparative analysis of the appearance, function, skin color, elasticity, and sensation of the healed chronic wounds revealed superior outcomes compared to traditional skin fl repairs, resulting in significantly higher satisfaction levels among patients and their families. Conclusion: The application of bilayer artificial dermis combined with VSD technology for the repair of chronic wounds proves to be a viable method, yielding satisfactory therapeutic effects compared to traditional skin flap procedures.

Zinc oxide nanoparticles accelerate the healing of methicillin-resistant Staphylococcus aureus(MRSA)-infected wounds in rabbits

Objective:To synthesize zinc oxide nanoparticles(ZnONPs)and evaluate their antibacterial and wound healing effects against wounds infected with methicillin-resistant Staphylococcus aureus(MRSA).Methods:ZnONPs were prepared by sol-gel method and characterized by X-ray diffraction(XRD)analysis and scanning electron microscopy(SEM).A total of 18 rabbits were divided into three groups:the ZnONPs group,the gentamicin group and the control group.A wound of 3 cm^(2) was inflicted on each rabbit and contaminated with MRSA inoculum.Treatment was started from the fourth day post-surgery.Wound healing,microbiological analysis,and histopathological analysis were performed to assess the efficacy of ZnONPs ointment.Results:XRD analysis confirmed the hexagonal wurtzite structure of the ZnONPs with an average crystallite size of 29.23 nm.SEM revealed discoid-shaped ZnONPs with a rough surface and an average size of 48.36 nm.Energy-dispersive X-ray analysis confirmed the purity of ZnONPs.Moreover,the particle size ranged from 100-700 nm with a high agglomeration trend.Treatment with ZnONPs promoted MRSA-infected wound healing.In addition,ZnONPs showed a good antibacterial effect as evidenced by a dose-dependent increase in the zone of inhibition.Conclusions:ZnONPs accelerate the healing of MRSA-infected wounds.Therefore,it can be explored for the treatment of MRSA infection.

Efficacy of lidocaine wet compress combined with red-light irradiation for chronic wounds

BACKGROUND Chronic wounds that fail to progress through normal phases of healing present a significant healthcare burden owing to prolonged treatment and associated costs.Traditional wound care typically involves regular dressing changes,which can be painful.Recent approaches have explored the use of lidocaine to manage pain and red-light irradiation(RLI),known for its anti-inflammatory and cell proliferation effects,to potentially enhance wound healing.AIM To investigate the therapeutic efficacy of lidocaine wet compression(LWC)combined with RLI for chronic wounds.METHODS We enrolled 150 patients with chronic wounds from the Wound and Ostomy Outpatient Clinic of the Second Hospital of Anhui Medical University from April to September 2022.The wounds were treated with dressing changes.The patients were randomly assigned to the control and experimental groups using a random number table and given the same first dressing change(2%LWC for 5 min and routine dressing change).From the second dressing change,in addition to 2%LWC for 5 min and routine dressing change,the experimental group received RLI,whereas the control group continued to receive the same LWC and dressing change.The first and second dressing changes were performed on days 1 and 2,respectively.The third dressing change was performed 3 d after the second change.The frequency of subsequent dressing changes was determined based on wound exudation and pain.Pain during the first three dressing changes was evaluated in both groups.The average number of dressing changes within 28 d and the degree of wound healing on day 28 were also recorded.RESULTS During the initial dressing change,no noticeable differences were observed in the pain levels experienced by the two groups,indicating similar pain tolerance.However,during the second and third dressing changes,the experimental group reported significantly less pain than the control group.Furthermore,over 28 d,the experimental group required fewer dressing changes than the control group.CONCLUSION Notably,the effectiveness of wound healing on the 28th day was significantly higher in the experimental group than that of in the control group.The combination of LWC and RLI was effective in reducing early-stage pain,promoting wound healing,decreasing the frequency of dressing changes,and enhancing patients’overall quality of life with chronic wounds.

Antibacterial Properties of Crateva adansonii (Capparidaceae) on Strains Isolated from Chronic Wounds Diagnosed in the Commune of Ouinhi in 2021

Plants have always been used by people for therapeutic purposes. They are still the main source of therapeutic substances in developing countries. Crateva adansonii, a member of the Capparidaceae family, is a medicinal plant with antibacterial properties used in Benin. The aim of this study was to assess the efficacy of an aqueous extract of C. adansonii on bacterial strains isolated from chronic wounds in the Ouinhi population. To achieve this, the bacterial flora present in chronic wounds was identified using the Ikram method (2014) coupled with the API Remoel One method. The antibacterial properties of the aqueous extract of C. adansonii on the microbial strains isolated were then assessed by determining the Inhibition Diameters (ID), the Minimum Inhibitory Concentrations (MIC) and finally the Minimum Bactericidal Concentrations (MBC). A total of eighty (80) strains were isolated and identified on the basis of morphological, cultural and biochemical characteristics. The species S. Aureus species accounted for the largest proportion (67.5%). Other species such as Listeria sp, Pseudomonas proteus, S. epidermidis and Bacillus cereus, Citrobacter freundii, Steno maltophila;Axin calcoaceticus, E. coli, K. pneumonia, Lem. richardii, Salmonella paratyphi A, Salmonella sp, Shigella sp were determined in variable proportions. At a concentration of 10 mg/ml, only S. aureus was sensitive to contact with the extract. However, at 20 mg/ml, 89% of strains were sensitive and 11% very sensitive. The highly sensitive strains are Salmonella sp and E. coli. The Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) are 20 mg/ml and 40 mg/ml respectively. The MBC/MIC ratio of the aqueous mixture of Crateva adansonii (Capparidaceae) varied from 1.2 to 2, with a bactericidal effect on 100% of the strains tested.

Management of Complex Wounds with Dermal Substitute Assisted by a Negative Pressure System

Introduction: The standard treatment for complex wound care is autografting. The advent of dermal substitutes has provided a novel tool for the preparation of the bed to be grafted. However, most types of dermal matrices require the application of a skin graft a second time. Currently, other strategies have been developed to improve the vascularization process, such as negative pressure wound therapy (NPWT), which has been reported to reduce the time required for vascular growth and dermal matrix integration and thus achieve a shorter waiting period for autologous graft application. The present study aims to evaluate the effectiveness and safety of dermal matrix management associated with NPWT in the treatment of complex wounds. Methods: Seven patients with a diagnosis of complex wounds were enrolled in this study between July 1, 2015, and June 31, 2016. After debridement and having an adequate wound bed, patients who met the criteria for the application of combined therapy were treated with dermal substitutes and a negative pressure system. The percentage of graft integration into the wound bed, complications, length of hospital stay, and duration of therapy were analyzed. Results: The mean age was 42.5 ± 16 (39 - 54) years old;three women and four men were included in the study. The approximate size of skin loss was 120.7 ± 75 cm2 (25 - 250 cm2). The combined therapy of dermal matrix plus NPWT was instituted in all cases for a period of 14 days. There were no complications, with 100% graft integration in 6 of 7 cases. Patients were discharged after a mean hospital stay of 5.4 days. Conclusions: This study demonstrates that the utilization of combined dermal matrix plus NPWT therapy can be performed safely and effectively in patients with complex wounds with low complication rates and a short hospital stay.

Antibacterial activities of selected medicinal plants in traditional treatment of human wounds in Ethiopia

Objective:To evaluate the activity of selected Ethiopian medicinal plants traditionally used for wound treatment against wound-causing bacteria.Methods:Samples of medicinal plants(Achyranthes aspera,Brucea antidysenteriea,Datura stramonium,Croton macrostachyus,Acokanthera xchimperi.,Phytolacca dodecandra,Milhttia ferruginea,and Solanum incanum)were extracted using absolute methanol and water and tested for their antimicrobial activities against clinical isolates and standard strains of wound-causing bacteria using agar well diffusion and micro titer plate methods.Results:Most of the plant extracts had antibacterial activities,among which Acokanthera schimperi and Brucea antidysenteriea inhibited growth of 100%and 35%of the test organisms,respectively.Methanolic extracts had higher activities compared with their corresponding aqueous extracts.The most susceptible organism to the extracts was Streptococcus pyogens while the most resistant were Escherichia coli and Proteus vulgaris.Conclusions:This finding justifies the use of the plants in wound healing and their potential activity against woundcausing bacteria.Their toxicity level and antimicrobial activity with different extraction solvents should further be studied to use them as sources and templates for the synthesis of drugs to control wound and other disease-causing bacteria.

Role of stem cell therapies in treating chronic wounds:A systematic review

BACKGROUND The impairment of cutaneous wound healing results in chronic,non-healing wounds that are caused by altered wound environment oxygenation,tissue injury,and permissive microbial growth.Current modalities for the treatment of these wounds inadequately address the complex changes involved in chronic wound pathogenesis.Consequently,stem cell therapies have emerged as a potential therapeutic modality to promote cutaneous regeneration through trophic and paracrine activity.AIM To investigate current literature regarding use of stem cell therapies for the clinical treatment of chronic,non-healing wounds.METHODS PubMed,EMBASE,Cochrane Library,Web of Science,and Scopus were queried with combinations of the search terms“mesenchymal stem cells,”“adult stem cells,”“embryonic stem cells,”“erythroid precursor cells,”“stem cell therapies,”and“chronic wounds”in order to find relevant articles published between the years of 2000 and 2019 to review a 20-year experience.Reference lists from the articles were reviewed to identify additional pertinent articles.Retrieved manuscripts(reviews,case reports/series,retrospective/prospective studies,and clinical trials)were evaluated by the authors for their depiction of clinical stem cell therapy use.Data were extracted from the articles using a standardized collection tool.RESULTS A total of 43 articles describing the use of stem cell therapies for the treatment of chronic wounds were included in this review.While stem cell therapies have been explored in in vitro and in vivo applications in the past,recent efforts are geared towards assessing their clinical role.A review of the literature revealed that adipose-derived stem cells,bone marrow-derived stem cells,bone marrowderived mononuclear cells,epidermally-derived mesenchymal stem cells,fibroblast stem cells,keratinocyte stem cells,placental mesenchymal stem cells,and umbilical cord mesenchymal stem cells have all been employed in the treatment of chronic wounds of various etiologies.Most recently,embryonic stem cells have emerged as a novel stem cell therapy with the capacity for multifaceted germ cell layer differentiation.With the capacity for self-renewal and differentiation,stem cells can enrich existing cell populations in chronic wounds in order to overcome barriers impeding the progression of wound healing.Further,stem cell therapies can be utilized to augment cell engraftment,signaling and activity,and resultant patient outcomes.CONCLUSION Assessing observed clinical outcomes,potential for stem cell use,and relevant therapeutic challenges allows wound care stakeholders to make informed decisions regarding optimal treatment approaches for their patients’chronic wounds.

Therapeutic effect of autologous concentrated growth factor on lower-extremity chronic refractory wounds:A case report

BACKGROUND Management of chronic refractory wounds is one of the toughest clinical challenges for surgeons.Because of poor blood supply,less tissue coverage,and easy exposure,the lower leg is a common site for chronic refractory wounds.The current therapeutic regimens often lead to prolonged hospital stay and higher healthcare costs.Concentrated growth factor(CGF)is a novel blood extract that contains various growth factors,platelets,and fibrins to promote wound healing process.However,there has been little research reported on the treatment of lower extremity wounds with CGF.CASE SUMMARY A 37-year-old man,without any past medical history,presented an ulcerated chronic wound on his right lower leg.The skin defect exhibited clear boundaries,with a size of 2.0 cm×3.5 cm.The depth of wound was up to the layer of deep fascia.Staphylococcus aureus was detected by bacterial culture.The final diagnosis was right lower extremity ulcers with infection.Cefathiamidine,silver sulfadiazine,and mupirocin cream were applied to control the infection.CGF gel was prepared from the patient’s blood sample,and was used to cover the wound after thorough debridement.The skin wound was successfully healed after three times of CGF treatment.CONCLUSION CGF displays an excellent wound healing promoting effect in patients with lowerextremity chronic refractory wounds.

Benefits of multidisciplinary collaborative care team-based nursing services in treating pressure injury wounds in cerebral infarction patients

BACKGROUND Cerebral infarction patients need to be bedridden for long periods of time often resulting in pressure injuries,which may represent a serious threat to patients'life and health.An effective nursing program should be adopted for timely intervention in patients with pressure wounds.AIM To explore the value of nursing services based on a multidisciplinary collaborative treatment team in patients with pressure injury wounds following cerebral infarction.METHODS Patients with cerebral infarction pressure injury wounds in our hospital from December 2016 to January 2021 were selected and divided into one study group and one control group based on the simple random number table method.The control group was treated with conventional nursing care(CNC),and the study group was treated with care services based on multidisciplinary collaborative care(MDCC).The Pressure Ulcer Scale for Healing(PUSH),healing effect,Self-Perceived Burden Score(SPBS),and satisfaction with the intervention were calculated before and after 2 and 4 wk of intervention in both groups.RESULTS Sixty-two patients were enrolled,and 31 patients were assigned to each group.The results of the interventions were as follows:(1)There was no significant difference between the PUSH scores of the MDCC group(11.19±2.46)and CNC group(12.01±2.79)before the intervention(P>0.05),and the PUSH scores were lower after 2 and 4 wk of intervention in the MDCC group(6.63±1.97 and 3.11±1.04)than in the CNC group(8.78±2.13 and 4.96±1.35 points)(P<0.05);(2)The rate of wound healing in the MDCC group(96.77%)was higher than that in the CNC group(80.65%)(P<0.05);(3)There was no significant difference between the SPBS scores of emotional factors(21.15±3.11),economic factors(9.88±2.15),and physical factors(8.19±2.23)in the two groups before the intervention.The scores of emotional factors(13.51±1.88),economic factors(6.38±1.44),and physical factors(5.37±1.08)were lower in the MDCC group than in the CNC group(16.89±2.05,7.99±1.68 and 7.06±1.19)after 4 wk of intervention(P<0.05);and(4)Satisfaction with the intervention was higher in the MDCC group(93.55%)than in the CNC group(74.19%)(P<0.05).CONCLUSION Interventions for patients with cerebral infarction pressure wounds based on an MDCC treatment team can effectively reduce patients'self-perceived burden,improve pressure wound conditions,facilitate wound healing,and increase patient satisfaction with the intervention.

A randomized controlled trial of topical tea tree preparation for MRSA colonized wounds

Background:The prevalence of MRSA(Methicillin-resistant Staphylococcus aureus)colonized wounds in home care residents is expected to grow continuously as a result of the substantial proportion of older people requiring institutionalized care due to chronic disease and declining functional status,which contribute to more frequent skin breakdown and wound formation.Tea tree oil has been claimed to have anti-bacterial,analgesic and anti-inflammatory effects that have been suggested in many in-vitro studies to have good efficacy against MRSA.The aims of this study were to evaluate the effectiveness of 10%topical tea tree preparation to eradicateMRSA and to ascertain its influence on wound healing forMRSA-colonized wounds.Methods:It was a randomized controlled trial,single-blind study.Those with stage II or above MRSA-colonized wounds and who had given their informed consent formed the sample.The determined sample sizewasbasedonthe effect size of our previouspilot study,whichwas 0.46.Five outcome measurements were taken for the MRSA bacterial count and wound healing condition at baseline and at 1-week intervals during the 4-week dressing intervention period.Results:Thirty-two participants were recruited from two non-government nursing homes,16 in the control group and 16 in the tea tree oil group.The control group residents received routine saline gauze dressing,while the tea tree oil group residents received the 10%topical tea tree preparation dressing.In the tea tree oil group,all chronic wounds that had previously been delayed in healing were healed within 28 days without adverse reaction.MRSA was also completely eradicated in 14(87.5%)out of 16 wounds in the group receiving the 10%topical tea tree preparation.

Effect of hydrogen intervention on refractory wounds after radiotherapy:A case report

BACKGROUND Patients with keloids who receive radiotherapy(RT)after surgery can develop refractory wounds that cannot be healed by the patient's own repair system.Such chronic wounds are uneven and complex due to persistent abscess and ulceration.Without external intervention,they can easily result in local tissue necrosis or,in severe cases,large area tissue resection,amputation,and even death.CASE SUMMARY This article describes the use of hydrogen to treat a 42-year-old female patient with a chronic wound on her left shoulder.The patient had a skin graft that involved implanting a dilator under the skin of her left shoulder,and then transferring excess skin from her shoulder onto scar tissue on her chest.The skin grafting was followed by two rounds of RT,after which the shoulder wound had difficulty healing.For six months,the patient was treated with 2 h of hydrogen inhalation(HI)therapy per day,in addition to application of sterile gauze on the wound and periodic debridement.We also performed one deep,large,sharp debridement to enlarge the wound area.The wound healed completely within 6 mo of beginning the HI treatment.CONCLUSION After HI therapy,the patient showed superior progress in reepithelialization and wound repair,with eventual wound closure in 6 mo,in comparison with the previous failures of hyperbaric oxygen and recombinant bovine basic fibroblast growth factor therapies.Our work showed that HI therapy could be a new strategy for wound healing that is cleaner,more convenient,and less expensive than other therapies,as well as easily accessible for further application in clinical wound care.

Healing Wounds under Mechanical Stress: A Case Example

This paper challenges the concept that the essential element in wound healing is to offload pressure. We suggest a change in approach that recognizes the integumentary system as one which, like all other body systems, adapts to the stresses put upon it. We use a clinical case example to illustrate the use of intentional mechanical stress to promote wound healing and include a review of the relevant literature. The intent of this publication is to call for a new look at clinical practice regarding wound healing and to call for future research directed at investigation of this theory.
