Abstract
INTRODUCTION Postoperative wound infection after spinal surgery might be a challenge to manage. A wide range of procedures have been described for managing infected spinal wounds. An increasingly common procedure in the management of surgical site infections (SSI) is negative pressure wound therapy (NPWT), also known as vacuum-assisted closure. As there is a paucity of clear clinical advice the present investigation aims to update current evidence on the use of NPWT to manage postoperative SSI occurring after instrumented spine surgery. METHODS This systematic review was conducted according to the preferred reporting Items for systematic reviews and meta-analyses: the 2020 PRISMA statement. In January 2024, the following databases were accessed: PubMed, Web of Science, and Google Scholar. No time constraint was set for the search. All the clinical studies investigating the unique use of NPWT in treating postoperative spinal wound infections were accessed. RESULTS A total of 381 patients were included in the present study. Of them 52.5% (200 of 381 patients) were women. The mean age was 52.2 ± 15.2 years. The average length of the NPWT was 21.2 days (range 7-90 days). CONCLUSION NPWT could be a valuable adjuvant therapy for the management of SSI after spine surgery. Additional high-quality investigations are required to assess the efficacy and safety of NPWT in SSI after spine surgery, especially if combined with contraindications or risk factors, such as the presence of intraoperative CSF leak. LEVEL OF EVIDENCE Level IV, Systematic review.

Abstract
Skin wounds accompanied by bacterial infections threaten human health, and conventional antibiotic treatments are ineffective for drug-resistant bacterial infections and chronically infected wounds. The development of non-antibiotic-dependent therapeutics is highly desired but remains a challenging issue. Recently, 2D silicene nanosheets with considerable biocompatibility, biodegradability, and photothermal-conversion performance have received increasing attention in biomedical fields. Herein, copper-containing nanoparticles-loaded silicene (Cu2.8O@silicene-BSA) nanosheets with triple enzyme mimicry catalytic (peroxidase, catalase, and oxidase-like) activities and photothermal function are rationally designed and fabricated for efficient bacterial elimination, angiogenesis promotion, and accelerated wound healing. Cu2.8O@silicene-BSA nanosheets display excellent antibacterial activity through synergistic effects of reactive oxygen species generated from multiple catalytic reactions, intrinsic bactericidal activity of released Cu2+ ions, and photothermal effects, achieving high antibacterial efficiencies on methicillin-resistant Staphylococcus aureus (MRSA) of 99.1 ± 0.7% in vitro and 97.2 ± 1.6% in vivo. In addition, Cu2.8O@silicene-BSA nanosheets exhibit high biocompatibility for promoting human umbilical vein endothelial cell (HUVEC) proliferation and angiogenic differentiation. In vivo experiments reveal that Cu2.8O@silicene-BSA nanosheets with synergistic photothermal/chemodynamic therapeutics effectively accelerate MRSA-infected wound healing by eliminating bacteria, alleviating inflammation, boosting collagen deposition, and promoting angiogenesis. This research presents a promising strategy to engineer photothermal-assisted nanozyme catalysis for bacteria-invaded wound healing.

Abstract
BACKGROUND Assessing the efficacy and safety of Vacuum Sealing Drainage (VSD) in treating deep incision infections (DII) following posterior cervical internal fixation. METHODS We retrospectively studied the clinical effects of VSD and Traditional Negative Pressure Drainage (TND) on 12 patients with deep incision infection after posterior cervical fixation surgery who were treated in our department from 2012 to 2020. A comparison of patient-related factors (age, gender, BMI, comorbidities, initial internal fixation surgery segment, preoperative laboratory inflammation indicators) and surgical-related factors (postoperative duration of fever, positive rate of drainage fluid bacterial culture, Visual Analogue Scale (VAS) score at 3 days after surgery, laboratory indicators at 3 days after surgery, debridement frequency and drainage time, hospital stay, internal fixation retention rate, and infection recurrence rate) between the VSD group and the TND group was conducted using independent sample t tests to draw experimental conclusions. RESULTS This study included 12 patients, with six cases of VSD (5 males and 1 female) and six cases of TND (4 males and 2 females). The VSD group had significantly lower postoperative fever time (1.50 ± 0.46 days vs. 4.28 ± 0.97 days, P < 0.05), a higher positive rate of bacterial cultures in drainage fluid (5/6 vs. 2/6, P < 0.05), lower 3 day VAS scores (3.13 ± 0.83 vs. 3.44 ± 0.88, P < 0.05), lower 3 day CRP levels (66.89 ± 23.65 mg/L vs. 57.11 ± 18.18 mg/L, P < 0.05), a shorter total drainage time (14.50 ± 2.98 days vs. 22.56 ± 3.01 days, P < 0.05), and a higher total drainage flow rate (395.63 ± 60.97 ml vs. 155.56 ± 32.54 ml, P < 0.05) than the TND group (the total drainage volume throughout the entire treatment process). In addition, the frequency of debridement (2.67 ± 0.52 times vs. 3.17 ± 0.41 times, P < 0.05) and average hospital stay (23.13 ± 3.27 days vs. 34.33 ± 6.86 days, P < 0.05) were significantly lower in the VSD group, although both groups retained internal fixation. CONCLUSIONS VSD is a secure and effective treatment for deep incision infections that results from cervical posterior internal fixation surgery.

Abstract
Implant-associated infection (IAI) is an unsolved problem in orthopaedics. Current therapies, including antibiotics and surgical debridement, can lead severe clinical and financial burdens on patients. Therefore, there is an urgent need to reinforce the inherent antibacterial properties of implants. Recently, two-dimensional (2D) silicene nanosheets (SNs) have gained increasing attention in biomedical fields owing to their considerable biocompatibility, biodegradability and strong photothermal-conversion performance. Herein, a dual-functional photosensitive coating on a Ti substrate (denoted as TPSNs) was rationally fabricated for bacterial inhibition and osteogenesis promotion. For the first time, SNs were loaded onto the surface of implants. Hyperthermia generated by the SNs and polydopamine (PDA) coating under 808 nm laser irradiation achieved the in vitro anti-bacterial efficiency of 90.7 ± 2.4 % for S. aureus and 88.0 ± 5.8 % for E. coli, respectively. In addition, TPSNs exhibited promising biocompatibility for the promotion of BMSC (bone marrow mesenchymal stem cells) proliferation and spreading. The presence of silicon (Si) in TPSNs contributed to the improved osteogenic differentiation of BMSCs, elevating the expressions of RUNX2 and OCN. In animal experiments, the combination of TPSNs with photothermal therapy (PTT) achieved an anti-bacterial efficiency of 89.2 % ± 1.6 % against S. aureus. Furthermore, TPSNs significantly improved bone-implant osseointegration in vivo. Overall, the development of a dual-functional TPSNs coating provides a new strategy for combating IAI.

Abstract
Chronic wound, such as skin defect after burn, pressure ulcer, and diabetic foot ulcer is very difficult to cure. Its pathological process is often accompanied with local temperature rise, pH decrease, and other phenomena. Owing to their outstanding hydrophilic, biocompatibility, and responsive properties, hydrogels could accelerate the healing process. In this study, we chose chitosan oligosaccharide (COS) grafted with Pluronic F127 (F127-COS). Aldehyde hyaluronic acid (A-HA) oxidized by NaIO4. And added boric acid (BA) to prepare a thermosensitive and pH-responsive injectable self-healing F127-COS/A-HA/COS/BA (FCAB) hydrogel, loaded with drug deferoxamine (DFO) in order to have an accurate release and promote angiogenesis of diabetic foot ulcer. In vitro experiments had verified that the FCAB hydrogel system loaded with DFO (FCAB/D) could promote migration and angiogenesis of HUVEC. A diabetes rat back wound model further confirmed its role in promoting angiogenesis in wound repair process. The results showed that the FCAB/D hydrogel exhibited unique physicochemical properties, excellent biocompatibility, and significantly enhanced therapeutic effects for diabetic foot ulcer.

Ultrasound-guided percutaneous micro-drainage tube irrigation combined with high negative pressure tube drainage versus debridement with closed suction irrigation for treating deep surgical site infection after spinal surgery. Int Wound J 2023; 21:e14435. [PMID: 37878524 PMCID: PMC10828718 DOI: 10.1111/iwj.14435] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 09/21/2023] [Accepted: 10/02/2023] [Indexed: 10/27/2023] Open
Abstract
It is difficult to avoid deep surgical site infection after spinal surgery. Debridement combined with closed suction irrigation (CSI) and other treatment methods lead to greater trauma and lower satisfaction. We developed a new method for the treatment of SSI, which has the advantages of less invasiveness and lower cost. The cohort of this retrospective study comprised 26 patients with SSI after undergoing spinal surgery in our hospital from August 2017 to March 2022. The patients were divided into CSI and microtube drainage group according to treatment methods. The durations of antibiotic use and hospital stay, hospitalization costs, and functional scores during follow-up were compared between the two groups. The only baseline characteristic that differed between the two groups was sex. Infection was controlled in both groups and there were no recurrences during follow-up. However, the length of hospital stay after the first operation and the total length of stay were significantly greater in the CSI group. Hospitalization costs and antibiotic costs were significantly higher in the CSI group. Additionally, the duration of intravenous antibiotic use was significantly longer in the CSI group. Both the CSI and microtube drainage groups had significantly improved of Short Form Health Survey (SF-36) scores 6 months postoperatively. However, 3 months postoperatively, SF-36 scores were significantly lower in the CSI group. Compared with debridement followed by CSI, percutaneous micro-drainage tube irrigation combined with high negative pressure tube drainage is a more efficient and economical means of treating SSI after spinal surgery.

Abstract
There are many debates regarding the risk factors of surgical site infection (SSI) following posterior cervical surgery in previous studies. And, till now there is no such a study to examine cervical laminoplasty surgery. From January 2011 through October 2021, a total of 405 patients who were treated with unilateral open-door laminoplasty surgeries were enrolled in this study. We divided the patients into the SSI group and the non-SSI group and compared their patient-specific and procedure-specific factors. Univariate and multiple logistic regression analysis were performed to determine the risk factors. Of the 405 patients, 20 patients had SSI. The rate of SSI found to be 4.93%. There were significant differences between groups in the thicker subcutaneous fat thickness (FT) (p < 0.001), the higher ratio of subcutaneous FT to muscle thickness (MT) (p < 0.001), the higher preoperative Japanese Orthopaedic Association (JOA) Scores (p < 0.003), the decreased preoperative serum albumin (p < 0.001), the more postoperative drainage (p < 0.05) and the longer time of draining (p < 0.001). Logistic regression analysis of these differences showed that the higher ratio of subcutaneous FT/MT, the higher preoperative JOA scores, the decreased preoperative serum albumin and the longer time of draining were significantly related to SSI (p < 0.05). The higher ratio of subcutaneous FT/MT, the higher preoperative JOA scores, the decreased preoperative serum albumin and the longer time of draining are identified as the independent risk factors of SSI in cervical laminoplasty. Identification of these risk factors could be useful in reducing the SSI incidence and patients counselling.

Abstract
PURPOSE After spinal surgery, negative pressure wound treatment (NPWT) improves deep surgical site infection (DSSI) wound healing. This research compared the healing benefits of two sponge implantation strategies in NPWT for DSSI. METHODS 21 patients with DSSI utilized NPWT to improve wound healing following spine surgery were followed from January 1, 2012 to December 31, 2021. After antibiotic treatment failure, all these patients with DSSI received extensive debridement and NPWT. They are grouped by sponge placement method: centripetal reduction and segment reduction. The two groups' hospital stays, NPWT replacement frequency, wound healing time, healing speed, and quality of wound healing (POSAS score) were compared. RESULTS All patients had been cured by the end of December 2022, and the mean follow-up time was 57.48 ± 29.6 months. Surgical incision length did not vary across groups (15.75±7.61 vs. 15.46±7.38 cm, P = 0.747). The segmental reduction approach had shorter hospital stay and NPWT treatment times than the centripetal reduction method (39.25±16.04 vs. 77.38±37.24 days, P = 0.027). Although there is no statistically significant difference, the mean wound healing duration of segmental reduction group is faster than that of centripetal reduction group (0.82±0.39 vs 0.45±0.28 cm/d, P = 0.238), wound healing quality (POSAS) (33.54±8.63 vs 48.13±12.17, P = 0.408) is better in segmental reduction group, and NPWT replacement frequency (2.62 ± 1.04 vs 3.88 ± 1.25, P < .915) is smaller in segmental reduction group. CONCLUSIONS NPWT heals wounds and controls infection. Segmental reduction method accelerates wound healing, reduces hospital stay, and improves wound quality compared to central reduction method.

Abstract
Surgical site infection (SSI) remains a major threat for implant failure in orthopedics. Herein, we report a dual-functional coating on Ti implants (named Ti/PDA/BP) with the integration of two-dimensional (2D) photo-sono sensitive black phosphorus nanosheets (BPNSs) and polydopamine (PDA) for efficient bacterial inhibition and bone-implant integration. For the first time, we employ BPNSs as generators of reactive radicals (ROS) under ultrasound (US) stimuli for implant associated infection. Additionally, the application of PDA improves the stability of BPNSs, the biocompatibility and photothermal performance of this hybrid coating. The as-prepared Ti/PDA/BP coating exhibits superior biocompatibility, bioactivity, photothermal and sonodynamic conversion abilities. Owing to the synergistic effect of hyperthermia and ·OH, Ti/PDA/BP damages the membrane and antioxidant system of Staphylococcus aureus, reaching a high antibacterial activity of 96.6% in vitro and 97.3% in vivo with rapid 10 min NIR irradiation and 20 min US treatment. In addition, we firstly unveil the significant effect of Ti/PDA/BP-based sonodynamic therapy (SDT) on bacterial membrane and oxidative stress at the transcriptome level. Moreover, the Ti/PDA/BP coating remarkably promotes osteogenesis in vitro and bone-implant osseointegration in vivo. Overall, development of Ti/PDA/BP bioactive coating provides a new strategy for combating the implant associated infection.

Abstract
BACKGROUND Postoperative incisional negative pressure wound vacuum-assisted closure (VAC) dressings are being used as a primary dressing to optimize wound healing and help avoid complications of infection and dehiscence. Few studies have investigated whether application of VAC dressings on postoperative posterior spinal wounds can reduce the incidence of surgical site infections. OBJECTIVE To describe our single-surgeon experience of using primary VAC after posterior spinal fusion (PSF) in a large sample of trauma patients. METHODS This was an Institutional Review Board-approved retrospective comparative study and included all trauma patients presenting to our level 1 safety-net trauma center who required PSF and were operated on by the senior surgeon between 2016 and 2021. Primary outcomes were complications (surgical site infection, readmission for infection, and wound-related return to operating room [OR]) within 90 days after surgery. χ2 testing and Student t testing were used to assess differences between treatment groups while bivariate and multivariate regression was performed for outcome assessment. RESULTS Two hundred sixty-four patients met criteria and were included. One hundred fifty-seven (59%) were treated with standard dressing and 107 (41%) with VAC. Patients treated with VAC were more likely to be older (P = .015), have diabetes (P = .041), have an elevated body mass index (P = .020), and had more levels of fusion (P = .002). Despite this, presence of VAC was independently associated with decreased 90-day infection (hazard ratio = 0.397, P = .023) and decreased 90-day return to OR for wound-related reasons (hazard ratio = 0.099, P = .031). CONCLUSION Compared with the use of standard dressing, VAC was found to decrease surgical site infection and return to OR risk in trauma patients undergoing PSF.

Abstract
PURPOSE To evaluate the efficacy and safety of negative pressure wound therapy (NPWT) for post-operative deep surgical site infection (SSI) after posterior instrumented spinal surgery. METHODS We retrospectively compared the clinical outcomes of NPWT with standard debridement for deep SSI after posterior instrumented spinal surgery from 2012 to 2020 in our department. The primary outcomes were peri-operative characteristics including positive organism results, duration of fever, and visual analogue scale (VAS) pain scores three days after re-operation. The secondary outcomes were post-operative characteristics including implant infection recurrence, implant retention rate, duration of hospitalization, and VAS at discharge. Pearson's chi-squared analysis (categorical) and Student's t test (continuous) were used to determine the differences. RESULTS Thirty-four patients were included, of which 19 underwent NPWT, and 15 underwent standard debridement. Patients in the NPWT group all significantly improved primary outcomes including duration of fever after re-operation (0.95 ± 1.13 vs 4.07 ± 5.35, P = 0.001), positive organism results (14 of 19 vs 2 of 15, P < 0.01), and VAS at 3 days after re-operation (2.58 ± 0.69 vs 3.40 ± 1.06, P < 0.05). Patients in NPWT group exhibited significant decrease in implant infection recurrence (0 of 19 vs 5 of 15, P < 0.01), implant retention rate (19 of 19 vs 10 of 15, P < 0.01), duration of hospitalization (27.74 ± 10.95 vs 37.67 ± 13.67, P < 0.01). CONCLUSIONS NPWT is a feasible and safe treatment option for deep SSI after posterior instrumented spinal surgery.

World Neurosurg 2022; 164:374-380. [PMID: 35671992 DOI: 10.1016/j.wneu.2022.05.138] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2022] [Revised: 05/30/2022] [Accepted: 05/31/2022] [Indexed: 11/30/2022]
Abstract
STUDY DESIGN Systematic review OBJECTIVE: The objective of this systematic review is to determine the fate of spinal implants when the patients develop postoperative wound infection after posterior instrumental fusion in a degenerative spine. METHODS A systematic review of the English-language literature (published between January 2001 and July 2020) was undertaken to identify articles documenting the management strategy for surgical-site infections after posterior lumbar spinal fusion. Studies on pedicle screw fixation after trauma, immunocompromised, metastatic spine disease, and combined anterior/posterior approach were excluded. Two independent reviewers assessed the level of evidence quality using the criteria set by the North American Spine Society, and disagreements were resolved by consensus. RESULTS Out of the 3,071 citations identified, 49 met the criteria to undergo full-text review. Outcomes after surgical site infections were studied from a combined pool of 1,150 patients undergone instrumental spinal fusion. The collected data showed that 456 patients (39.97%) had undergone spinal implant removal following SSI while 694 patients (60.03%) had their implants retained until the resolution of SSI. There was an absolute risk reduction of 29% (ARR-0.292) and a relative risk reduction of 50.3% (RRR- 0.503) of implant removal if the patient underwent wound debridement following SSI. The NNT for wound debridement was calculated at 3.31 from our pooled cohort. The absolute risk reduction in implant removal following VAC therapy was 16.6% and relative risk reduction was noted at 40.4%. This led to a high value of NNT at 6.0 patients. There was an absolute risk reduction of 33.5% while a Relative Risk Reduction of 70.7% was estimated in patients undergoing continuous irrigation. CONCLUSION Our review of the literature suggests that successful eradication of surgical site infection after posterior lumbar spinal fusion can be achieved by wound debridement or VAC therapy with appropriate antimicrobial coverage in most cases. Implant removal is generally reserved for cases refractory to the other treatment modalities.

Abstract
OBJECTIVES To describe the novel technique of continuous local antibiotic perfusion (CLAP) for a surgical site infection (SSI) after instrumented spinal surgery. METHODS CLAP was applied to 4 continuous patients at our institution who developed SSI after instrumented spinal surgery. RESULTS All 4 patients were successfully treated and the infection was controlled. The implant was retained in all patients. The duration of CLAP ranged from 2 to 3 weeks. The blood level of the antibiotic used (gentamicin) at 1 week after the initiation of CLAP did not increase in any patient. No other adverse events occurred in any patient. Dramatic improvements in laboratory parameters, including the white blood cell (WBC) counts and C-reactive protein (CRP) levels were seen in every patient at 1 week after the initiation of CLAP. CONCLUSIONS CLAP controlled the infection without severe adverse events in all 4 patients, and the implants were retained. Despite its cost and the discomfort of patients, CLAP may become an option for the treatment of SSIs after instrumented spinal surgery. A large number of case series are needed to verify the efficacy of CLAP for patients with SSIs after instrumented spinal surgery.

Abstract
PURPOSE Study of negative pressure wound therapy (NPWT) safety for patients with intraoperative exposure of the dura. METHODS We analyzed the literature on the NPWT usage after spinal surgery in patients with exposure of the dura. We also described our experience of NPWT in 3 pediatric patients with spinal dysraphism. Due to the peculiarities of the anatomy (spina bifida), all of these patients had dural sac exposure during spinal surgery. RESULTS The reasons for NPWT in all three cases were different. In the first patient with segmental spinal dysgenesis, surgery was complicated by extensive postoperative wound necrosis and the formation of soft tissue deficiency. The second patient with post-myelomeningocele kyphosis had a deficiency of soft tissues during spinal surgery due to a large bedsore at the apex of the deformity. And in the third patient also with post-myelomeningocele kyphosis, NPWT was applied with surgical site infection. In all three cases, NPWT was used when the dura was exposed, without complications and with satisfactory results. The observation period for the patients was 3 years, 2.5 years, and 2 years, respectively. CONCLUSIONS The usage of NPWT in cases of wound complications in the spinal surgery may be a useful option, which allows saving implants. NPWT is not contraindicated in cases of intraoperative dural exposure if there are no signs of cerebrospinal fluid (CSF) leak.

Abstract
OBJECTIVE To introduce a novel technique of using incisional vacuum-assisted closure (VAC) after 1-stage incision suture combined with closed suction irrigation system (CSIS) for treating early deep surgical site infection (SSI) after posterior lumbar fusion with instrumentation and to compare it with traditional CSIS. METHODS This was a retrospective study. Patients with early deep SSI after posterior lumbar fusion with instrumentation from January 2013 to May 2020 who were treated by meticulous debridement followed by either CSIS or incisional VAC after 1-stage incision suture combined with CSIS were identified. The demographic characteristics, treatment features, and outcomes were analyzed and compared between the 2 treatment methods. RESULTS A total of 48 patients (48/5016, 0.96%) developed early deep SSI, 46 of whom were enrolled in this study. This included 24 patients in the CSIS group (group 1) and 22 patients in the incisional VAC after 1-stage incision suture combined with CSIS group (group 2). All patients received follow-up, with an average of 19.7 months (range, 13-30 months). There were no significant differences in demographic characteristics in both groups (P > 0.05). The number of VAC foam dressing or ordinary dressing changes (P < 0.001), number of debridements (P = 0.028), intravenous antibiotic duration (P = 0.042), oral antibiotic duration (P = 0.019), and hospital stay (P = 0.029) in group 1 were significantly higher than those in group 2. The irrigation duration in group 1 was significantly shorter than that in group 2 (P = 0.007). All patients were eventually cured with satisfactory outcomes. CONCLUSIONS Compared with CSIS, incisional VAC after 1-stage incision suture combined with CSIS may be recommended considering that it has fewer dressing changes, fewer debridements, longer irrigation duration, shorter duration of antibiotic use, shorter hospital stay, and more convenient nursing care.

Abstract
Background Previous reports concerning deep surgical site infection (SSI) after posterior spinal instrumentation treated with vacuum-assisted closure (VAC) system indicated that most patients must suffer from a delayed incision suture. To date, there are no published reports about the application of incisional VAC following a one-stage incision suture in the treatment of spinal infections. The purpose of this study was to evaluate the feasibility and efficacy of using an incisional VAC system following a one-stage incision suture combined with continuous irrigation to treat early deep SSI after posterior lumbar fusion with instrumentation. Methods Twenty-one patients who were identified as early deep SSI after posterior lumbar fusion with instrumentation were treated by incisional VAC following a one-stage incision suture combined with continuous irrigation at our spine surgery center between January 2014 and March 2020. Detailed data from medical records were collected and analyzed, including age, gender, primary diagnosis, original operation, number of VAC dressing changes, duration of continuous irrigation, hospital stay, risk factors for infection, bacteria type, and laboratory data. Clinical efficacy was assessed using the pre- and postoperative visual analog scale (VAS) for back pain and Kirkaldy-Willis functional criteria by regular follow-up. Results All the patients were cured and retained implants with an average of 1.9 times of VAC dressing replacement, and an average of 10.2 days of continuous irrigation. There were significant differences between pre-operation and post-operation in ESR, CRP, and VAS score of back pain, respectively (P < 0.05). The satisfactory rate was 90.5% according to Kirkaldy-Willis functional criteria. One patient developed a back skin rash with itching around the wound because of long-time contact with the VAC dressing. There was no recurrent infection or other complications during follow-up. Conclusions Our preliminary results support that the treatment protocol is feasible and effective to treat early deep SSI following posterior lumbar fusion with instrumentation.

Abstract
OBJECTIVE Negative pressure wound therapy is one of the most common treatments for infected wounds. The aim of this meta-analysis was to compare the efficacy of negative pressure wound therapy with conventional treatment methods in the treatment of surgical site infection. DESIGN This study is registered with International Prospective Register of Systematic Reviews. DATA SOURCES The Pubmed, Embase and the Cochrane Central Register of Controlled Trials databases were searched. METHODS The systematic review was searched by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses method. All trials reporting the use of negative pressure wound therapy for surgical site infection treatment were included regardless of surgery type. The primary outcome measure was wound healing. Secondary outcomes were length of hospital stay, medical costs, adverse events, and reoperation rates. Results are presented with 95% confidence intervals and report estimates as odds ratios. Heterogeneity was determined through the I2 test, with I2 > 50% indicating substantial heterogeneity and p < .10 significance. The search was performed on 10 March 2020. RESULTS We identified 13 eligible trial comparisons, of which 2 were randomized controlled trials and 11 cohort study. Negative pressure wound therapy in surgical site infection (SSI) patients significantly increased wound healing rate, accelerated wound healing time, increased daily wound healing area, reduced hospital stay, and reduced adverse events. However, negative pressure wound therapy was associated with increased medical costs. CONCLUSION Negative pressure wound therapy may be more effective for the treatment of surgical site infection relative to conventional debridement, dressings and other treatments. However, further high-quality randomized controlled trials are needed to determine the most optimal application of negative pressure wound therapy. IMPACT Negative pressure wound therapy is the best treatment strategy for surgical site infection. This study can improve medical practitioners' awareness of negative pressure wound therapy for surgical site infection, promoting the development of relevant randomized controlled trials.

Purpose High rate of perineal surgical site infection (SSI) is the most common complication following abdominoperineal resection (APR), especially for extralevator abdominoperineal excision (ELAPE). The purpose of this study was to investigate the effect of continuous negative pressure drainage combined with intermittent irrigation (CNPDCII) in the presacral space on the perineal SSI following laparoscopic ELAPE for low rectal cancer. Patients and Methods The clinical data of 99 patients with low rectal cancer who underwent laparoscopic ELAPE surgery were retrospectively analyzed. Among the 99 patients, 46 patients received CNPDCII and 53 patients received conventional drainage in the presacral space after ELAPE. Self-made irrigation drainage tube: took a silicone drainage tube, cut 3 side holes at every 2cm intervals at the front end, and fixed a flexible tube of an intravenous needle at the front end of the silicone drainage tube. The conventional drainage tube or self-made irrigation drainage tube was placed in the presacral space and poked out from the inside of the ischial tuberosity. The incidence of SSI and other perioperative indicators between the two groups was compared within 30 days after surgery. Results There was no statistical difference in clinicopathological features between the two groups of patients (p>0.05). A statistically lower rate of SSI was found in CNPDCII group (17.4%, 8/46) than the conventional drainage group (35.8%, 19/53). The drainage tube retention time (7.8±1.2 d VS 9.4±1.6 d) and the postoperative hospital stay (9.7±1.4 d VS 11.9±2.3 d) in CNPDCII group were significantly shortened than the conventional drainage group. There was no statistical difference in operating theatre time and intraoperative blood loss between the two groups. Multivariate analysis confirmed that CNPDCII was an independent protective factor for SSI after ELAPE. Conclusion CNPDCII can effectively reduce the incidence of SSI following laparoscopic ELAPE, which is simple, safe and effective.

Abstract
Post-operative wound complications are some of the most common acute complications following spine surgery. These surgical site infections (SSI) contribute to increased healthcare related costs. Negative pressure wound therapy (NPWT) has long been used for treatment of soft tissue injury or defects. NPWT may reduce the incident of SSI following spinal fusion procedures; however, its potential applications need further clarification. Thus, we conducted a retrospective analysis of two cohorts to compare NPWT to traditional sterile dressings following spinal fusions in regards to post-operative outcomes. Following institutional review board approval, 42 patients who had a NPWT were matched by type of surgery to 42 patients who had traditional dressings. A retrospective chart-review was completed. Outcome measures, particularly SSI and need for reoperation, were analyzed using one-way ANOVA for both univariate and multivariate analysis. When controlled for sex and body-mass index, the use of a NPWT was independently correlated with decreased SSI (P = .035). Superficial dehiscence, seroma, need for additional outpatient care, and need for operative revision were all found to occur at higher rates in the traditional dressing cohort. Closed incisional negative pressure wound therapy provides a cost-effective method of decreasing surgical site infection for posterior elective spine surgeries.
