RESUMEN
OBJECTIVE: Incisional negative pressure wound therapy (iNPWT) applied over all incisions after lower extremity bypass in the prevention of surgical site infections (SSIs) is unclear. The primary and secondary aims of this study were to investigate if prophylactic iNPWT after the elective lower extremity bypass prevents SSI and other surgical wound complications. METHODS: This was a multicenter, parallel, randomized controlled trial. Patients undergoing elective lower extremity bypass in 3 hospitals were randomized to either iNPWT or standard dressings. SSIs or other wound complications were assessed within the first 90 days by wound care professionals blinded to the randomized result. The validated Additional treatment, Serous discharge, Erythema, Purulent exudate, Separation of deep tissues, Isolation of bacteria, and Stay (ASEPSIS) score was used to objectively assess the wounds. ASEPSIS score ≥21 is defined as an SSI. Unilateral and bilateral groups were analyzed with the Fisher exact test and the McNemar test, respectively. RESULTS: In the unilateral group (n = 100), the incidence of SSI in the iNPWT group was 34.9% (15/43), compared with 40.3% (23/57) in the control group, according to the ASEPSIS score (P = .678). In the bilateral group (n = 7), the SSI rate was 14.3% (1/7) in the iNPWT group compared with 14.3% (1/7) in the control group (P = 1.00). In the unilateral group, there was a higher wound dehiscence rate in the control group (43.9%) compared with the iNPWT group (23.3%) (P = .0366). No serious iNPWT-related adverse events were recorded. CONCLUSIONS: There was no reduction of SSI rates in leg incisions with iNPWT compared with standard dressings in patients undergoing elective lower extremity bypass, whereas iNPWT reduced the incidence of wound dehiscence.

INTRODUCTION: Negative pressure wound therapy (NPWT) is part of the temporary abdominal closure in the treatment of patients with traumatic, inflammatory, or vascular disease. However, the use of NPWT when performing an intestinal anastomosis has been controversial. This study aimed to describe the patients managed with NPWT therapy and identify the risk factors for anastomotic dehiscence when intestinal anastomosis was performed. METHODS: A single-center cohort study with prospectively collected databases was performed. Patients who required NPWT therapy from January 2014 to December 2018 were included. Patients were stratified according to the performance of intestinal anastomosis and according to the presence of dehiscence. Bivariate and multivariate analyses were performed for anastomotic dehiscence and mortality. RESULTS: A total of 97 patients were included. Median age was 52 y old [interquartile range 24.5-70]. Male patients corresponded to 75.6% (n = 34) of the population. Delayed fascial closure was performed in 80% (n = 36). The risk of anastomotic dehiscence was higher in females (odds ratio (OR) 11.52 [confidence interval (CI) 1.29-97.85], P = 0.030), delayed fascial closure (OR 18.18 [CI 2.02-163.5], P = 0.010) and use of vasopressors (OR 12.04 [CI 1.22-118.47], P = 0.033). NPWT pressures >110 mmHg were evidenced in the dehiscence group with statistically significant value (OR 1.2 [0.99-2.26] p 0.04) CONCLUSIONS: There is still controversy in the use of NPWT when performing intestinal anastomosis. According to our data, the risk of dehiscence is higher in females, delayed fascial closure, use of vasopressors, and NPWT pressures >110 MMHG.

OBJECTIVE: This study assessed the potential benefits of using incisional negative pressure wound therapy (iNPWT) for patients undergoing revascularisation due to peripheral arterial disease. METHODS: A prospective randomised controlled trial was conducted to compare the inguinal application of iNPWT vs. standard surgical dressings. Patients were enrolled from February 2021 to November 2022. A total of 133 groin incisions were randomised (66 intervention group, 67 control group). The randomisation sequence was carried out by permuted blocks and allocation assigned by opening opaque envelopes once the revascularisation procedure had finished. Wound healing and complication rates were assessed at post-operative days 5, 14, and 30. Primary and secondary endpoints were: 30 day post-operative surgical site infection (SSI) and surgical site occurrence (SSO) rates, defined as a surgical wound complication other than a SSI. Post-operative SSI was defined according to the US Centers for Disease Control and Prevention criteria. SSO included: wound dehiscence, seroma or lymphocele, haematoma, and lymphorrhagia. The study was registered at ClinicalTrials.gov database (NCT04840576) and reported according to the CONSORT guidelines. RESULTS: iNPWT did not modify the 30 day inguinal SSI and SSO rates (16.7% vs. 20.9% and 37.9% vs. 44.8%; p = .53, relative risk [RR] 0.999, 95% confidence interval [CI] 0.52 - 1.88 and p = .42, RR 1.29, 95% CI 0.89 - 1.86, respectively). It reduced the early SSO rate (19.7% vs. 35.8%; p = .044, RR 1.45, 95% CI 1.047 - 2.013) and post-operative seroma rate (4.6% vs. 19.4%; p = .014, RR 1.73, 95% CI 1.296 - 2.397). CONCLUSION: There were no differences in SSI and SSO rates, although statistically significant reductions in early SSO rates and seroma were found in the intervention group.

OBJECTIVE: Open abdomen therapy (OAT) is commonly used to prevent or treat abdominal compartment syndrome (ACS) in patients with ruptured abdominal aortic aneurysms (rAAAs). This study aimed to evaluate the incidence, treatment, and outcomes of OAT after rAAA from 2006 to 2021. Investigating data on resuscitation fluid, weight gain, and cumulative fluid balance could provide a more systematic approach to determining the timing of safe abdominal closure. METHODS: This was a single centre observational cohort study. The study included all patients treated for rAAA followed by OAT from October 2006 to December 2021. RESULTS: Seventy-two of the 244 patients who underwent surgery for rAAA received OAT. The mean age was 72 ± 7.85 years, and most were male (n = 61, 85%). The most frequent comorbidities were cardiac disease (n = 31, 43%) and hypertension (n = 31, 43%). Fifty-two patients (72%) received prophylactic OAT, and 20 received OAT for ACS (28%). There was a 25% mortality rate in the prophylactic OAT group compared with the 50% mortality in those who received OAT for ACS (p = .042). The 58 (81%) patients who survived until closure had a median of 12 (interquartile range [IQR] 9, 16.5) days of OAT and 5 (IQR 4, 7) dressing changes. There was one case of colocutaneous fistula and two cases of graft infection. All 58 patients underwent successful abdominal closure, with 55 (95%) undergoing delayed primary closure. In hospital survival was 85%. Treatment trends over time showed the increased use of prophylactic OAT (p ≤ .001) and fewer ACS cases (p = .03) assessed by Fisher's exact test. In multivariable regression analysis fluid overload and weight reduction predicted 26% of variability in time to closure. CONCLUSION: Prophylactic OAT after rAAA can be performed safely, with a high rate of delayed primary closure even after long term treatment.

BACKGROUND: To analyze surgical site infections (SSIs) after infrainguinal bypass for standard dressings versus closed incision negative pressure wound therapy (ciNPWT) in the Society for Vascular Surgery's Vascular Quality Initiative (VQI). METHODS: We retrospectively analyzed SSI after infrainguinal bypass procedures in the VQI from December 2019 to December 2021 comparing ciNPWT and standard dressings. The primary outcome of any superficial or deep wound infection at 30 days was analyzed in a subset of procedures with 30-day follow-up data (cohort A, n = 1,575). Secondary outcomes including in-hospital SSI, return to the operating room (OR) for infection, and length of stay (LOS) were analyzed for all procedures (cohort B, n = 9,288). Outcomes were analyzed in propensity-matched cohorts. RESULTS: Patients who received ciNPWT (n = 1,389) were more likely to be female (34% vs. 32%, P = 0.04) with a higher rate of smoking history (90% vs. 86%, P = 0.003), diabetes (54% vs. 50%, P = 0.007), obesity (34% vs. 26%, P < 0.001), prior peripheral vascular intervention (57% vs. 51%, P < 0.001), and to prosthetic conduit (55% vs. 48%, P < 0.001) compared to patients with standard dressings (n = 7,899). After propensity matching of cohort A (n = 1,256), the 30-day SSI rate was 4% (12/341) in the ciNPWT and 6% (54/896) in the standard dressing group (P = 0.07, 95% CI 0.03-1.06). In the propensity-matched in-hospital cohort B (n = 5,435), SSI was 3% (35/1,371) in the ciNPWT group and 2% (95/4,064) in the standard dressing group (P = 0.66). There was no difference in the rate of return to the OR for infection, 1% (36/4,064) vs. 1% (19/1,371) (P = 0.13) or LOS, 9.0 vs. 9.0 days (P = 0.86) for the standard versus ciNPWT groups. CONCLUSIONS: In this analysis of the VQI registry, the use of ciNPWT after infrainguinal bypass did not result in a statistically significant decrease in 30-day SSI. We recommend that surgeons consider the use of ciNPWT as part of a bundled process of care for high risk rather than all patients, as it may reduce SSI after infrainguinal bypass.

A judicious, well-planned bone and soft tissue debridement remains one of the cornerstones of state-of-the-art treatment of fracture-related infection (FRI). Meticulous surgical excision of all non-viable tissue can, however, lead to the creation of large soft tissue defects. The management of these defects is complex and numerous factors need to be considered when selecting the most appropriate approach. This narrative review summarizes the current evidence with respect to soft tissue management in patients diagnosed with FRI. Specifically we discuss the optimal timing for tissue closure following debridement in cases of FRI, the need for negative microbiological culture results from the surgical site as a prerequisite for definitive wound closure, the optimal type of flap in case of large soft tissue defects caused by FRI and the role of negative pressure wound therapy (NPWT) in FRI. Finally, recommendations are made with regard to soft tissue management in FRI that should be useful for clinicians in daily clinical practice.Level of evidence Level V.

INTRODUCTION: Endoscopic vacuum therapy (EVT) is a novel technique for closing upper gastrointestinal (UGI) defects. Available literature includes single-center retrospective cohort studies with small sample sizes. Furthermore, evidence about factors associated with EVT failure is scarce. We aimed to assess the efficacy and safety of EVT for the resolution of UGI defects in a multicenter study and to investigate the factors associated with EVT failure and in-hospital mortality. METHODS: This is a prospective cohort study in which consecutive EVT procedures for the treatment of UGI defects from 19 Spanish hospitals were recorded in the national registry between November 2018 and March 2022. RESULTS: We included 102 patients: 89 with anastomotic leaks and 13 with perforations. Closure of the defect was achieved in 84 cases (82%). A total of 6 patients (5.9%) had adverse events related to the EVT. The in-hospital mortality rate was 12.7%. A total of 6 patients (5.9%) died because of EVT failure and 1 case (0.9%) due to a fatal adverse event. Time from diagnosis of the defect to initiation of EVT was the only independent predictor for EVT failure (odds ratio [OR] 1.03, 95% confidence interval [CI] 1.01-1.05, P = 0.005). EVT failure (OR 24.5, 95% CI 4.5-133, P = 0.001) and development of pneumonia after EVT (OR 246.97, 95% CI 11.15-5,472.58, P = 0.0001) were independent predictors of in-hospital mortality. DISCUSSION: EVT is safe and effective in cases of anastomotic leak and perforations of the upper digestive tract. The early use of EVT improves the efficacy of this technique.

OBJECTIVE: Groin surgical site infections (SSIs) after open revascularization can lead to devastating consequences in patients. As a result, prevention has been crucial in minimizing the rate of SSIs. This review aims to evaluate the current body of literature regarding prevention ,techniques including prophylactic flaps, incision technique, topical antibiotic use, closed-incision negative pressure wound therapy, and adhesive drapes. METHODS: This review was conducted and reported in accordance with the PRISMA statement. A systematic review was conducted using the Google Scholar, PubMed, and Cochrane Review databases regarding the five prevention topics. The authors identified 1371 potential studies with 33 studies selected and analyzed after systematic review regarding the five preventative topics. RESULTS: The primary outcome of interest was how the rate of SSI was affected with each preventative technique. As a result, the recommendations are as follows. We suggest prophylactic flaps be considered in high-risk surgical patients undergoing open arterial exposure of the groin (Grade 2C). We suggest consideration of transverse incisions for open arterial exposure of the groin as a means of SSI prevention (Grade 2C). Given the lack of data regarding topical antibiotics no recommendation can be made regarding its use, we suggest closed-incision negative pressure wound therapy be used in groin surgical incisions at high risk for SSI (Grade 2B). Given the paucity of data regarding adhesive drapes, such as Ioban, no recommendation can be made regarding its use. CONCLUSIONS: This review highlights the effects of various preventative techniques and their potential benefit in the prevention of SSI in the groin. However, there is a glaring deficit in the available data, emphasizing the need for additional robust studies to better delineate their effectiveness and implementation into surgical practice. The use of endovascular techniques continues to increase, thus limiting the number of open arterial procedures and the potential for further studies to be conducted. To provide the high-quality studies needed to better evaluate these prevention techniques, large multi-institutional collaboration will likely be necessary to provide the appropriate number of patients to evaluate true effectiveness.

INTRODUCTION: The aim of this study was to evaluate the indications and management of grade III-IV postoperative complications in patients requiring vacuum-assisted open abdomen after debulking surgery for ovarian carcinomatosis. METHODS: Retrospective study of prospectively collected data from patients who underwent a cytoreductive surgery by laparotomy for an epithelial ovarian cancer that required postoperative management of an open abdomen. An abdominal vacuum-assisted wound closure (VAWC) was applied in cases of abdominal compartmental syndrome (ACS) or intra-abdominal hypertension, to prevent ACS. The fascia was closed with a suture or a biologic mesh. The primary aim was to achieve primary fascial closure. Secondary outcomes considered included complications of cytoreductive surgery (CRS) and open abdominal wounds (hernia, fistula). RESULTS: Two percent of patients who underwent CRS required VAWC during the study's patient inclusion period. VAWC indications included: (i) seven cases of gastro-intestinal perforation, (ii) three necrotic enterocolitis, (iii) two intestinal ischemia, (iv) three anastomotic leakages and (v) four intra-abdominal hemorrhages. VAWC was used to treat indications (i) to (iv) (which represented 73.7% of cases), to prevent compartmental syndrome. Primary fascia closure was achieved in 100% of cases, in four cases (21.0%) a biologic mesh was used. Median hospital stay was 65 days (range: 18-153). Four patients died during hospitalization, three of these within 30 days of VAWC completion. CONCLUSION: VAWC for managing open abdominal wounds is a reliable technique to treat surgical post-CRS complications in advanced ovarian cancer and reduces the early post-operative mortality in cases presenting with severe complications.

BACKGROUND: With the increasing incidence of upper digestive tract tumors, more upper digestive tract surgeries are performed each year, and surgeons have difficulty in the postoperative management of gastrointestinal anastomotic fistula. The use of a new minimally invasive technique, endoluminal vacuum-assisted closure (E-VAC), has increased the success rate of the treatment of gastrointestinal fistula. METHODS: We present 6 cases of gastrointestinal fistula treated in our hospital in 2021: 3 cases of anastomotic fistula after esophageal cancer surgery, 2 cases of anastomotic fistula after gastric cancer surgery, and one case of esophageal rupture after trauma. With E-VAC and other adjuvant treatment measures, the gastrointestinal fistulas were eventually closed or significantly reduced. RESULTS: Both local and systemic infections in all 6 patients were controlled with the use of E-VAC device, resulting in significant reduction or closure of fistulas. CONCLUSION: E-VAC devices can effectively help in the removal of the exudate and necrotic tissue around the fistula, promote the proliferation of granulation tissue, and support closure of the fistula. However, further improvements to the device are needed to improve patient comfort and operational safety.

BACKGROUND: While endoscopic vacuum assisted closure (EVAC) therapy is a validated treatment for gastrointestinal leaks, its impact on long-term quality of life (QoL) is uncertain. The purpose of this study was to evaluate the impact of successful EVAC management on long-term QoL outcomes. METHODS: An institutional review board approved prospectively maintained database was retrospectively reviewed to identify patients undergoing treatment for gastrointestinal leaks between June 2012 and July 2022. The Short-Form 36 (SF-36) survey was used to assess QoL. Patients were contacted by telephone and sent the survey electronically. QoL outcomes between patients who underwent successful EVAC therapy and those who required conventional treatment (CT) were analyzed and compared. RESULTS: A total of 44 patients (17 EVAC; 27 CT) completed the survey and were included in our analysis. All included patients had foregut leaks with sleeve gastrectomy being the most common sentinel operation (n = 20). The mean time from the sentinel operation was 3.8 years and 4.8 years for the EVAC and CT groups, respectively. When evaluating long-term QoL, the EVAC group scored higher in all QoL domains when compared to the CT group with physical functioning (87.3 vs 69.3, p = 0.04), role limitations due to physical health (84.1 vs 45.7, p = 0.02), energy/fatigue (60.0 vs 40.9, p = 0.04), and social functioning (86.2 vs 64.1, p = 0.04) reaching statistical significance. Overall, patients who achieved organ preservation via successful EVAC therapy scored higher in all domains with role limitations due to physical health (p = 0.04) being statistically significant. In a multivariable regression analysis, increased age and a history of prior abdominal surgery at the time of the sentinel operation were patient characteristics that negatively impacted QoL outcomes. CONCLUSION: Patients with gastrointestinal leaks successfully managed by EVAC therapy have better long-term QoL outcomes when compared to patients undergoing other treatments.

BACKGROUND: Duodenal defects are complex clinical situations, and their management is challenging and associated with high mortality. Besides surgery, endoscopic treatment options exist, but the size and location of the perforation can limit their application. We present a retrospective study, demonstrating a successful application of endoscopic vacuum therapy (EVT) for duodenal leaks. METHODS: We performed a retrospective study of all patients who underwent EVT for duodenal perforations between 2016 and 2021 at two tertiary centers. We analyzed demographic and clinical patient characteristics, surgical outcomes, leak characteristics, sponge-related complications, and success rate. RESULTS: Indications for treatment with EVT in the duodenum consisted of leak after duodenal suture of a perforated ulcer (n = 4), iatrogenic perforation after endoscopic resection (n = 2), iatrogenic perforation during surgery (n = 2), and anastomotic leak after upper gastrointestinal surgery (n = 2). EVT was used as a first-line treatment in seven patients and as a second-line treatment in three patients. EVT was successfully applied in all interventions (n = 10, 100%). Overall, EVT lead to definitive closure of the defects in eight out of ten patients (80%). No severe EVT-related adverse events occurred. CONCLUSION: EVT is safe and technically feasible, so it emerges as a promising endoscopic treatment option for duodenal leaks. However, multidisciplinary collaboration and management are important to reduce the occurrence of postoperative complications, and to improve recovery rates.

BACKGROUND: Endoscopic treatment of esophageal leaks, mostly by covered stents or endoscopic vacuum therapy (EVT), has largely improved the clinical outcome in the last decade. However, both techniques suffer from significant limitations. Covered stents are hampered by a high rate of migration and missing functional drainage, whereas endoluminal EVT devices are limited by obstruction of the GI tract. The new design of the VACStent makes it a fully covered stent within a polyurethane sponge cylinder, allowing EVT while stent passage is still open. Initial clinical applications have demonstrated the fundamental concept of the VACStent. METHOD: A prospective multicenter open-label study was performed with the primary endpoint safe practicality, complete leak coverage, and effective suction-treatment of esophageal leaks. Secondary endpoints were prevention of septic conditions, successful leak healing, and complications, in particular stent-migration, local erosions and bleeding. RESULTS: Fifteen patients with different, mostly postoperative anastomotic leaks were enrolled in three centers. A total of 41 VACStents were implanted. The mean number of VACStents per patient was 2.7, with a mean duration of VACStent treatment of 15 days. The primary endpoint was met in all VACStent applications (41/41 implants), resulting in a leak healing rate of 80% (12/15 patients). Septic episodes were prevented in 93% (14/15 patients) and there was no mortality. There were no severe device-related adverse events (SADE) nor significant local bleeding or erosion. Minor stent-dislocation and migration, respectively, was observed in 7%. Oral intake of liquids or food was documented in 87% (13/15 patients). One anastomotic stenosis was seen during follow-up. CONCLUSIONS: VACStent treatment is a safe and effective treatment in esophageal leaks which can be covered by the sponge cylinder. Its application was described as easy and resembling that of conventional GI stents, with an impressive clinical success rate comparable to EVT outcomes. The VACStent offers a new option for clinical treatment of critical situations in esophageal perforations and anastomotic sutureline failures.

BACKGROUND: Management of anastomotic leaks after Ivor-Lewis esophagectomy remains a challenge. Although intracavitary endoscopic vacuum therapy (EVT) has shown great efficacy for large dehiscences, the optimal management of smaller leaks has not been standardized. This study aims to compare EVT versus self-expandable metal stent (SEMS) in the treatment of leaks < 30 mm in size, due to the lack of current data on this topic. METHODS: Patients undergoing EVT (cases) or SEMS (controls) between May 2017 and July 2022 for anastomotic leaks < 3 cm following oncologic Ivor-Lewis esophagectomy were enrolled. Controls were matched in a 1:1 ratio based on age (± 3 years), BMI (± 3 kg/m2) and leak size (± 4 mm). RESULTS: Cases (n = 22) and controls (n = 22) showed no difference in baseline characteristics and leak size, as per matching at enrollment. No differences were detected between the two groups in terms of time from surgery to endoscopic treatment (p = 0.11) or total number of procedures per patient (p = 0.05). Remarkably, the two groups showed comparable results in terms of leaks resolution (90.9% vs. 72.7%, p = 0.11). The number of procedures per patient was not significant between the two cohorts (p = 0.05). The most frequent complication in the SEMS group was migration (15.3% of procedures). CONCLUSION: EVT and SEMS seem to have similar efficacy outcomes in the treatment of anastomotic defects < 30 mm after Ivor-Lewis esophagectomy. However, larger studies are needed to corroborate these findings.

BACKGROUND: Wound complication, skin blister formation in particular, causes devastating consequences after total knee arthroplasty (TKA). Negative Pressure Wound Therapy (NPWT) tries to improve wound management leading to decrease length of hospital stay and better clinical outcomes. Low body mass index (BMI) could play a part in wound recovery management although lacking evidence. This study compared length of hospital stay and clinical outcomes between NPWT and Conventional groups, and factors affected and how BMI affected. METHODS: This was a retrospective clinical record review of 255 (160 NPWT and 95 Conventional) patients between 2018 and 2022. Patient demographics including body mass index (BMI), surgical details (unilateral or bilateral), length of hospital stay, clinical outcomes including skin blisters occurrence, and major wound complications were investigated. RESULTS: Mean age of patients at surgery was 69.95 (66.3% were female). Patients treated with NPWT stayed significantly longer in the hospital after joint replacement (5.18 days vs. 4.55 days; p = 0.01). Significantly fewer patients treated with NPWT found to have blisters (No blisters: 95.0% vs. 87.4%; p = 0.05). In patients with BMI < 30, percentage of patients requiring dressing change was significantly lower when treated with NPWT than conventional (0.8% vs. 33.3%). CONCLUSION: Percentage of blisters occurrence in patients who underwent joint replacement surgery is significantly lower using NPWT. Patients using NPWT stayed significantly longer in the hospital after surgery because significant proportion received bilateral surgery. NPWT patients with BMI < 30 were significantly less likely to change wound dressing.

INTRODUCTION: The susceptibility to surgical site occurrence (SSO) is high following ventral hernia repair (VHR) surgery. SSO severely increases the physical and mental burden on patients. The main purpose of this review was to analyze the efficacy of negative pressure wound therapy (NPWT) after open VHR(OVHR) and explore benefits to patients. METHODS: The Cochrane Library, PubMed, and Embase databases were searched from the date of establishment to 15 October 2022. All randomized controlled trials and retrospective cohort studies comparing NPWT with standard dressings after OVHR were included. The Revman 5.4 software recommended by Cochrane and the STATA16 software were used in this meta-analysis. RESULTS: Fifteen studies (involving 1666 patients) were identified and included in the meta-analysis, with 821 patients receiving NPWT. Overall, the incidence rate of SSO in the NPWT group was lower compared to the control group (odds ratio [OR] = 0.44; 95% confidence interval [CI] = 0.21-0.93; I2 = 86%; P = 0.03). The occurrence rate of surgical site infection (SSI; OR = 0.51; 95% CI = 0.38-0.68, P < 0.001), wound dehiscence (OR = 0.64; 95% CI = 0. 43-0.96; P = 0.03), and hernia recurrence (OR = 0.51; 95% CI = 0.28-0.91, P = 0.02) was also lowered. There was no significant difference in seroma (OR = 0.76; 95% CI = 0.54-1.06; P = 0.11), hematoma (OR = 0.53; 95% CI = 0.25-1.11; P = 0.09), or skin necrosis (OR = 0.83; 95% CI = 0.47-1.46; P = 0.52). CONCLUSION: NPWT can effectively decrease the occurrence of SSO, SSI wound dehiscence and hernia recurrence and should be considered following OVHR.

OBJECTIVES: Endoscopic vacuum therapy (EVT) possesses a unique mechanism of action providing a less invasive alternative for the management of transmural gastrointestinal defects (TGID). This study evaluates the efficacy and safety of a novel homemade EVT (H-EVT) for the treatment of TGID. METHODS: Retrospective multicenter study including patients who underwent H-EVT for TGID between January 2019 and January 2022. Main outcomes included technical and clinical success as well as safety outcomes. Subgroup analyses were included by defect location and classification. Logistic regression analyses were performed to determine predictors for successful closure. RESULTS: A total of 144 patients were included. Technical success was achieved in all patients, with clinical success achieved in 88.89% after a mean of 3.49 H-EVT exchanges over an average of 23.51 days. After excluding 10 cases wherein it was not possible to achieve negative pressure, successful closure occurred in 95.52% of patients. Time to clinical success was less for defects caused by endoscopic (hazard ratio [HR] 0.63; 95% confidence interval [CI] 0.33-1.20) compared to surgical procedures and for patients with simultaneous intracavitary and intraluminal H-EVT placement (HR 0.70; 95% CI 0.55-0.91). Location and classification of defect did not impact clinical success rate. Simultaneous placement of both an intraluminal and intracavitary H-EVT (odds ratio 3.08; 95% CI 1.19-7.95) was a significant predictor of clinical success. Three device-related adverse events (2.08%) occurred. CONCLUSIONS: The use of the H-EVT is feasible, safe, and effective for the management of TGID.

BACKGROUND AND AIMS: We investigated whether the use of a prophylactic negative pressure wound therapy (NPWT) system in women undergoing caesarean would decrease wound complications in a high-risk population. MATERIALS AND METHODS: A randomised controlled trial was performed. Women with risk factors for wound complications undergoing caesarean delivery were randomised to a standard dressing or NPWT placed over their caesarean wound. We standardised the closure of the subcutaneous fat and skin layers, both with Vicryl. Patients were followed for wound complications for up to 6 weeks after their caesareans. The incidence of wound complications was the primary outcome. The single-use NPWT system, PICO, was provided by Smith and Nephew for use in this trial. The trial was registered on clinicaltrials.gov, # NCT03082664. RESULTS: We report here on 154 women randomised to either a standard dressing or to the NPWT. Wound complication rates were equivalent between groups, with 19.4 and 19.7% (P = 0.43) of women with follow-up information available experiencing wound complications. CONCLUSION: We found no difference in wound complications in women with risk factors treated with a prophylactic NPWT system or standard wound dressing at the time of caesarean birth.

INTRODUCTION: High body mass index (BMI) and wound drainage following total joint arthroplasty (TJA) can lead to wound healing complications and periprosthetic joint infection. Silver-embedded occlusive dressings and negative pressure wound therapy (NPWT) have been shown to reduce these complications. The purpose of this prospective trial was to compare the effect of silver-embedded dressings and NPWT on wound complications in patients with BMI ≥ 35 m/kg2 undergoing TJA. METHODS: We conducted a randomized control trial of patients who had a BMI > 35 m/kg2 and were undergoing primary TJA between October 2017 and February 2020. Patients who underwent revision surgery, or those with an active infection, previous scar, history of wound healing complications, post-traumatic degenerative joint disease with hardware, or inflammatory arthritis were excluded. Patients were randomized to receive either a silver-embedded occlusive dressing (control) or NPWT. Frequency distributions, means, and standard deviations were used to describe patient demographics, postoperative complications, 90-day readmissions, and reoperations. T-test and chi-squared tests were used to test for significant differences between continuous and categorical variables, respectively. RESULTS: Two hundred-thirty patients with 3-month follow-up were included. One-hundred-fifteen patients received the control and 115 patients received NPWT. There were six patients (5.2%) in the control group with wound complications (drainage: n = 5, non-healing wound: n = 1) and two patients (1.7%) in the NPWT with complications (drainage: n = 2). There were no 90-day readmissions in the control group versus two (1.8%) 90-day readmissions in the NPWT group. Finally, three patients (2.6%) in the control group underwent reoperations (irrigation and debridement [I&D], I&D with modular implant exchange, and implant revision), while none in the NPWT group had undergone reoperation. The two groups showed insignificant differences in wound complications (p = 0.28), 90-day readmissions (p = 0.50), and reoperations (p = 0.25). CONCLUSION: Patients with BMI ≥ 35 m/kg2 undergoing TJA have no statistical difference in early wound complications, readmissions, or reoperations when treated with either silver-embedded dressings or NPWT.

PURPOSE: The purpose of this study was to determine whether a single-use negative pressure wound therapy (NPWT) system achieves individualized goals of therapy when used to treat patients with a variety of wound types. DESIGN: Multiple case series. SUBJECTS AND SETTING: The same comprised 25 participants; their mean age was 51.2 years (SD: 18.2; range: 19-79 years); 14 were male (56%) and 11 were female (44%). Seven study participants withdrew from study participation. Wound etiologies vary; 4 had diabetic foot ulcers; 1 had a full-thickness pressure injury; 7 were treated for management of an abscess or cyst; 4 had necrotizing fasciitis, 5 had nonhealing postsurgical wounds, and 4 had wounds of other etiologies. Data were collected at 2 ambulatory wound care clinics located in the Southeastern United States (Augusta and Austell, Georgia). METHODS: A single-outcome measure was selected for each participant by his or her attending physician at a baseline visit. Selected end points were (1) decrease in wound volume, (2) decrease in size of the tunneling area, (3) decrease in size of the undermining, (4) decrease in the amount of slough, (5) increase in granulation tissue formation, (6) decrease in periwound swelling, and (7) wound bed progression toward transition to another treatment modality (such as standard dressing, surgical closure, flap, or graft). Progress toward the individualized goal was monitored until the goal was achieved (study end point) or a maximum of 4 weeks following initiation of treatment. RESULTS: The most common primary treatment goal was to achieve a decrease in wound volume (22 of 25 study participants), and the goal to increase granulation tissue was chosen for the remaining 3 study participants. A majority of participants (18 of 23, 78.3%) reached their individualized treatment outcome. The remaining 5 participants (21.7%) were withdrawn during the study (for reasons not related to the therapy). The median (interquartile range [IQR]) duration of NPWT therapy was 19 days (IQR: 14-21 days). Between baseline and the final assessment, median reductions in wound area and volume were 42.7% (IQR: 25.7-71.5) and 87.5% (IQR: 30.7-94.6). CONCLUSIONS: The single-use NPWT system achieved multiple individualized treatment objectives in a variety of wound types. Individually selected goals of therapy were met by all study participants who completed the study.
