RESUMO
BACKGROUND: After esophagectomy, the postoperative rate of anastomotic leakage is up to 30% and is the main driver of postoperative morbidity. Contemporary management includes endoluminal vacuum sponge therapy (EndoVAC) with good success rates. Vacuum therapy improves tissue perfusion in superficial wounds, but this has not been shown for gastric conduits. This study aimed to assess gastric conduit perfusion with EndoVAC in a porcine model for esophagectomy. MATERIAL AND METHODS: A porcine model (n = 18) was used with gastric conduit formation and induction of ischemia at the cranial end of the gastric conduit with measurement of tissue perfusion over time. In three experimental groups EndoVAC therapy was then used in the gastric conduit (- 40, - 125, and - 200 mmHg). Changes in tissue perfusion and tissue edema were assessed using hyperspectral imaging. The study was approved by local authorities (Project License G-333/19, G-67/22). RESULTS: Induction of ischemia led to significant reduction of tissue oxygenation from 65.1 ± 2.5% to 44.7 ± 5.5% (p < 0.01). After EndoVAC therapy with - 125 mmHg a significant increase in tissue oxygenation to 61.9 ± 5.5% was seen after 60 min and stayed stable after 120 min (62.9 ± 9.4%, p < 0.01 vs tissue ischemia). A similar improvement was seen with EndoVAC therapy at - 200 mmHg. A nonsignificant increase in oxygenation levels was also seen after therapy with - 40 mmHg, from 46.3 ± 3.4% to 52.5 ± 4.3% and 53.9 ± 8.1% after 60 and 120 min respectively (p > 0.05). An increase in tissue edema was observed after 60 and 120 min of EndoVAC therapy with - 200 mmHg but not with - 40 and - 125 mmHg. CONCLUSIONS: EndoVAC therapy with a pressure of - 125 mmHg significantly increased tissue perfusion of ischemic gastric conduit. With better understanding of underlying physiology the optimal use of EndoVAC therapy can be determined including a possible preemptive use for gastric conduits with impaired arterial perfusion or venous congestion.

BACKGROUND: Traumatic esophageal perforations (TEP) are a grave medical condition and require immediate intervention. Techniques such as Esophageal Self-Expandable Metal Stent (E-SEMS) and Endoscopic Vacuum Therapy (EVT) show promise in reducing tissue damage and controlling esophageal leakage. The present study aims to compare the application of EVT to E-SEMS placement in TEP. METHODS: Retrospective cohort study valuated 30 patients with TEP. The E-SEMS and EVT groups were assessed for time of hospitalization, treatment duration, costs, and clinical outcome. RESULTS: Patients treated with EVT (24.4 ± 13.2) demonstrated significantly shorter treatment duration (p < 0.005) compared to the group treated with E-SEMS (45.8 ± 12.9) and patients submitted to E-SEMS demonstrated a significant reduction (p = 0.02) in the time of hospitalization compared to the EVT (34 ± 2 vs 82 ± 5 days). Both groups demonstrated a satisfactory discharge rate (E-SEMS 93.7% vs EVT 71.4%) but did not show statistically significant difference (p = 0.3155). E-SEMS treatment had a lower mean cost than EVT (p < 0.05). Descriptive statistics were utilized, arranged in table form, where frequencies, percentages, mean, median, and standard deviation of the study variables were calculated and counted. The Fisher's Exact Test was used to evaluate the relationship between two categorical variables. To evaluate differences between means and central points, the parametric t-test was utilized. Comparisons with p value up to 0.05 were considered significant. CONCLUSION: E-SEMS showed a shorter time of hospitalization, but a longer duration of treatment compared to EVT. The placement of E-SEMS and EVT had the same clinical outcome. Treatment with E-SEMS had a lower cost compared with EVT.

PURPOSE: Anastomotic leak (AL) represents the most relevant and devastating complication in colorectal surgery. Endoscopic vacuum therapy (EVT) using the VACStent is regarded as a significant improvement in the treatment of upper gastrointestinal wall defects. The innovative concept of the VACStent was transferred to the lower GI tract, gaining initial experience by investigating safety and efficacy in 12 patients undergoing colorectal resections. METHODS: The pilot study, as part of a German registry, began with 2 patients suffering from AL, who were treated with the VACStent after stoma placement. Subsequently, 6 patients with AL were treated with the VACStent omitting a stoma placement, with a focus on fecal passage and wound healing. Finally, the preemptive anastomotic coverage was investigated in 4 patients with high-risk anastomoses to avoid prophylactic stoma placement. RESULTS: In total 26 VACStents were placed without problems. The conditioning and drainage function were maintained, and no clogging problems of the sponge cylinder were observed. No relevant clinical VACStent-associated complications were observed; however, in 2 patients, a dislodgement of a VACStent occurred. The 6 patients with AL but without stoma had a median treatment with 3 VACStents per case with a laytime of 17 days, leading to complete wound healing in all cases. The 4 prophylactic VACStent applications were without complications. CONCLUSION: The clinical application of the VACStent in the lower GI tract shows that successful treatment of anastomotic colonic leaks and avoidance of creation of an anus praeter is possible. TRIAL REGISTRATION NUMBER: Clinicaltrials.gov NCT04884334, date of registration 2021-05-04, retrospectively registered.

BACKGROUND: Lateral Epicondylalgia (LE) represents one of the most common injuries of the upper limb. It is necessary to find effective treatments that reduce pain and increase functionality. PURPOSE: To determine the effects of an integrated intervention of Pulsed Negative Pressure Myofascial Vacuum Therapy (VT), Percutaneous Electrolysis (PE) and eccentric exercise (EE) in the treatment of LE compared versus Manual Therapy soft tissue mobilization (MT) and Ultrasound therapy (US) and EE. STUDY DESIGN: Single-blind randomized controlled trial. METHODS: Forty participants, with unilateral LE, were randomly divided into two groups: VT + PE + EE group (n = 20) and MT + US + EE group (n = 20). The VT + PE + EE group received one weekly session for four weeks and a regimen of EE daily at-home, and the MT + US + EE group received 10 sessions over a period of two weeks and a regimen of EE daily at-home. Numerical pain rating scale (NPRS), range of motion (ROM) pressure pain threshold (PPT) and function (PRTEE questionnaire) were measured before treatment, at the end of treatment, and at one- and three-month follow-ups. RESULTS: The statistically significant improvements were found post-treatment, favoring the VT + PE group in pain intensity (p < 0.001; ES = 0.408), PRTEE-S Pain (p = 0.001; ES = 0.377), PRTEE-S Specific function (p = 0.004; ES = 0.306) and PRTEE-S Total (p = 0.001; ES = 0.355). The VT + PE + EE treatment showed greater effectiveness than the MT + US + EE treatment at immediate post-treatment, as well as at the one-month and three-months follow-up. CONCLUSIONS: VT and PE added to an EE program could be an effective treatment for pain, ROM, PPT, and function in patients with LE.
RESUMO
OBJECTIVE: To compare the results of endoscopic vacuum therapy (EVT) and open surgery for esophageal perforations. MATERIAL AND METHODS: The study included 60 patients with esophageal perforations between 2010 and 2022. The main group included 29 patients who underwent minimally invasive treatment with EVT, the control group - 31 patients after open surgical interventions. RESULTS: Pneumonia occurred in 21 (72%) and 14 (45%) patients (p=0.04), esophageal stenosis within the perforation zone - in 4 (13.8%) and 1 (3.2%) patient, respectively (p=0.188). Chronic esophageal fistulas were significantly more common in the control group (6 (20.7%) versus 15 (48.4%) patients, p=0.032). The overall duration of treatment (median) among survivors was significantly shorter in the main group: 33 (23; 48) versus 71.5 (59; 93.7) days (p=0.5). However, length of ICU-stay was slightly higher (11 (6; 16) versus 8.5 (5; 12.75) days, p=0.32). Mortality rate was 13.8% (n=4) and 29% (n=9), respectively (p=0.213). Minimally invasive technologies decreased the risk of fatal outcome by 10 times (OR 10.123, 95% CI 1.491-124.97, p=0.035) compared to traditional surgery. CONCLUSION: EVT in complex minimally invasive treatment of patients with mechanical esophageal injuries is an effective method significantly reducing mortality and duration of inpatient treatment compared to traditional surgical approach.

PURPOSE: The treatment of anastomotic leakage after left colorectal surgery remains challenging. Since its introduction, endoscopic negative pressure therapy (ENPT) has proven to be advantageous, reducing the necessity of surgical revision. The aim of our study is to present our experience with endoscopic treatment of colorectal leakages and to identify potential factors influencing treatment outcome. METHODS: Patients who underwent endoscopic treatment of colorectal leakage were retrospectively analyzed. Primary endpoint was the healing rate and success of endoscopic therapy. RESULTS: We identified 59 patients treated with ENPT between January 2009 and December 2019. The overall closure rate was 83%, whereas only 60% of the patients were successfully treated with ENPT and 23% needed further surgery. The time between diagnosis of leakage and uptake of endoscopic treatment did not influence the closure rate, but patients with chronic fistula (> 4 weeks) showed a significantly higher reoperation rate than those with an acute fistula (94% vs 6%, p = 0.01). CONCLUSION: ENPT is a successful treatment option for colorectal leakages, which appears to be more favorable when started early. Further studies are still needed to better describe its healing potential, but it deserves an integral role in the interdisciplinary treatment of anastomotic leakages.

BACKGROUND AND AIMS: Colorectal endoscopic vacuum therapy (CR EVT) is usually performed using sponges passed through the anus. It may be associated with patient discomfort and displacement of the aspiration tube. METHODS: With the tube-in-tube endoscopic vacuum therapy modification (CR TT-EVT), it is possible to position the aspiration tube in the pelvic cavity through the abdominal wall. In addition, it allows frequent cleaning of the fistula, eliminates the need for programmed device changes, and enables a standardized approach to such a wide variety of fistulas, leaks, and perforations. RESULTS: Here is a technical note on how to perform CR TT-EVT, while we are at the early phase of our case series we have reached 100% of technical success.

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: 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.

OBJECTIVE OF THE STUDY: In esophageal surgery, anastomotic leak (AL) remains one of the most severe and critical adverse events after oncological esophagectomy. Endoscopic vacuum therapy (EVT) can be used to treat AL; however, in the current literature, treatment outcomes and reports on how to use this novel technique are scarce. The aim of this study was to evaluate the outcomes of patients with an AL after IL RAMIE and to determine whether using EVT as an treatment option is safe and feasible. MATERIAL AND METHODS: This study includes all patients who developed an Esophagectomy Complications Consensus Group (ECCG) type II AL after IL RAMIE at our center between April 2017 and December 2021. The analysis focuses on time to EVT, duration of EVT, and follow up treatments for these patients. RESULTS: A total of 157 patients underwent an IL RAMIE at our hospital. 21 patients of these (13.4%) developed an ECCG type II AL. One patient died of unrelated Covid-19 pneumonia and was excluded from the study cohort. The mean duration of EVT was 12 days (range 4-28 days), with a mean of two sponge changes (range 0-5 changes). AL was diagnosed at a mean of 8 days post-surgery (range 2-16 days). Closure of the AL with EVT was successful in 15 out of 20 patients (75%). Placement of a SEMS (Self-expandlable metallic stent) after EVT was performed in four patients due to persisting AL. Overall success rate of anastomotic sealing independently of the treatment modality was achieved in 19 out of 20 Patients (95%). No severe EVT-related adverse events occurred. CONCLUSION: This study shows that EVT can be a safe and effective endoscopic treatment option for ECCG type II AL.

BACKGROUND: Anastomotic leakages after esophagectomies continue to constitute significant morbidity and mortality. Intrathoracic anastomoses pose a high risk for mediastinitis, sepsis, and death, if a leak is not addressed timely and appropriately. However, there are no standardized treatment recommendations or algorithms as for how to treat these leakages. METHODS: The study included all patients at the University Hospital Regensburg, who developed an anastomotic leakage after esophagectomy with gastric pull-up reconstruction from 2007 to 2022. Patients receiving conventional treatment options for an anastomotic leakage (stents, drainage tubes, clips, etc.) were compared to patients receiving endoscopic vacuum-assisted closure (eVAC) therapy as their mainstay of treatment. Treatment failure was defined as cervical esophagostomy formation or death. RESULTS: In total, 37 patients developed an anastomotic leakage after esophagectomy with a gastric pull-up reconstruction. Twenty patients were included into the non-eVAC cohort, whereas 17 patients were treated with eVAC. Treatment failure was observed in 50% of patients (n = 10) in the non-eVAC cohort and in 6% of patients (n = 1) in the eVAC cohort (p < 0.05). The 90-day mortality in the non-eVAC cohort was 15% (n = 3) compared to 6% (n = 1) in the eVAC cohort. Cervical esophagostomy formation was required in 40% of cases (n = 8) in the non-eVAC cohort, whereas no patient in the eVAC cohort underwent cervical esophagostomy formation. CONCLUSION: eVAC therapy for leaking esophagogastric anastomoses appears to be superior to other treatment strategies as it significantly reduces morbidity and mortality. Therefore, we suggest eVAC as an essential component in the treatment algorithm for anastomotic leakages following esophagectomies, especially in patients with intrathoracic anastomoses.

PURPOSE: This study aimed to investigate the effect of epicutaneous vacuum therapy on the rate of unplanned spinal wound revisions compared with conventional wound dressing. METHODS: This retrospective study included patients who underwent unplanned revision spine surgery after primary aseptic spine surgery who were treated at a level I spine centre between December 2011 and December 2019. Patients with revision surgery who required a further unplanned revision surgery during the inpatient stay were considered a treatment failure. The epicutaneous vacuum-assisted closure (Epi-VAC) therapy was the standard treatment method beginning in 2017 (the epi-VAC group). Before, conventional wound dressing was used (the control group (CG)). In addition, a one-to-one matched-pair comparison analysis was performed between both groups. RESULTS: Of 218 patients, 48 were in the epi-VAC group. The mean age was 65.1 years (epi-VAC 68.2 to CG 64.3 years (P = 0.085)), and the mean body mass index (BMI) was 28.2 kg/m2 (epi-VAC 29.4 to CG 27.9 kg/m2 (P = 0.16)). No significant differences in the treatment failure rate could be detected between the two groups (epi-VAC 25% to CG 22.4% (P = 0.7)). There was also no significant difference for the matched-pair analysis (epi-VAC 26.1% to CG 15.2% (P = 0.3)). An elevated CRP level (C-reactive protein) immediately before the first wound revision was a significant risk factor for further revision surgery (treatment failure: 135.2 ± 128.6; no treatment failure: 79.7 ± 86.1 mg/l (P < 0.05)). CONCLUSION: Concerning repeat unplanned wound revision after spinal revision surgery, we cannot demonstrate an advantage of the epicutaneous vacuum therapy over conventional wound dressing.

OBJECTIVE: To evaluate the effectiveness and clinical aspects of advanced endoscopic vacuum therapy for esophagogastric, esophagointestinal and gastrointestinal anastomotic leakage, to identify disadvantages and further possibilities for its improvement. MATERIAL AND METHODS: The study included 69 people. Esophagodudodenal anastomotic leakage was detected in 34 patients (49.27%), gastroduodenal anastomotic leakage - in 30 patients (43.48%), esophagogastric anastomotic leakage - in 4 (7.25%) patients. Advanced endoscopic vacuum therapy was used for these complications. RESULTS: Vacuum therapy in patients with esophagodudodenal anastomotic leakage led to complete healing of defect in 31 (91.18%) cases. In 4 (14.8%) cases, minor bleeding was noted during replacement of vacuum dressing. There were no other complications. Three (8.82%) patients died from secondary complications. Treatment of gastroduodenal anastomotic failure resulted complete healing of defect in 24 (80%) patients. Six (20%) patients died including 4 (66.67%) cases associated with secondary complications. Vacuum therapy for esophagogastric anastomotic leakage resulted complete healing of defect in 4 (100%) patients. CONCLUSION: Advanced endoscopic vacuum therapy is a simple, effective and safe method of therapy for esophagogastric, esophagoduodenal and gastrointestinal anastomotic leakage.

The incidence of intestinal fistulas after laparotomy for various reasons (peritonitis, acute pancreatitis or trauma) is 1.5%. Fistula formation in patients with chronic gastrointestinal diseases has a rapid onset, severe course, and poor prognosis. Against the background of a long course of the disease and depletion of the body, there is a decrease in the activity of reparative processes, which leads to the manifestation of postoperative complications: the formation of fistulas, insolvency of intestinal anastomoses, peritonitis. Vacuum drainage is a treatment method aimed at eliminating exudate, reducing the area of the wound and its epithelization. The inclusion of a succinate-containing solution in the treatment regimen improves metabolic processes and improves the prognosis of the disease. As an illustration, a description of the clinical observation of patients with similar pathology and different treatment regimens is given.

OBJECTIVE: To analyze the results of simultaneous surgical treatment of sternomediastinitis compared to stage-by-stage approach. MATERIAL AND METHODS: The study included 27 patients between October 2022 and March 2023. All patients underwent heart surgery through median sternotomy. There were 11 (40.7%) women and 16 (59.3%) men. Mean age of patients was 68.4±9.8 years. All patients were divided into 2 groups: 12 patients underwent partial necrectomy and vacuum wound therapy (or long-term dressings) before surgery (group 1), 15 patients underwent surgery without prior conservative treatment (group 2). RESULTS: The most common causative agent of infection was staphylococcus (48.1%). In all patients, we found histological signs of osteomyelitis. Preoperative clinical status was similar in both groups. There were differences in the following indicators: C-reactive protein upon admission - 74.9±18.6 versus 94.8±23.8 mg/l, procalcitonin - 0.13 [0.02; 1.43] versus 0.21 [0.02; 0.94] ng/ml. Postoperative outcomes were similar in both groups. Mortality was 8.3% (n=1) and 13.3% (n=2), respectively. CONCLUSION: Simultaneous combined surgical treatment (sequestrectomy + muscle flap grafting) demonstrates optimal results in the treatment of sternomediastinitis.

BACKGROUND: Endoscopic vacuum therapy (EVT) has become a standard treatment method for esophageal perforations in adults. However, experience with EVT in infants is scarce. In this retrospective case series, we report on four very young infants who were successfully treated with EVT for esophageal perforations of different etiology. METHODS: Four infants were diagnosed with esophageal perforations on day 7, 32, 35 and 159 of life, respectively. The youngest one was prematurely born in the 31st week of pregnancy weighing 980 g only. Three infants had perforations due to foreign body insertion (nasogastric tube or pulling through of percutaneous endoscopic gastrostomy (PEG) tube through the esophagus). One child had an anastomotic dehiscence after Foker's surgery for atresia. In three children EVT was applied as first-line therapy for perforation, in one child EVT was a rescue therapy due to persisting leakage after surgical closure involving thoracotomy. Depending on the esophageal diameter, either an open-pore drainage film or polyurethane sponge was attached to a single-lumen 8 Fr suction catheter, endoscopically (or fluoroscopically by wire-guidance) placed into the esophagus (intraluminal EVT) and supplied with continuous negative pressure (ranging between 75 and 150 mmHg). The EVT system was exchanged twice per week. RESULTS: Complete closure of the perforation/leakage could be achieved in all four infants (100%) after 22 days of continuous EVT (median value; range 7-39) and 4.5 EVT exchanges (median value; range 1-12). No serious adverse events occurred. CONCLUSIONS: EVT is an effective and safe addition to our therapeutic armamentarium in the management of esophageal perforations irrespective of its etiology. Here we prove the feasibility of EVT even in very young infants. The use of an extra thin vacuum open-pore drainage film is helpful to cope with the small esophageal diameter. EVT settings and exchange rates similar to those known from adult treatment were used.

BACKGROUND: Obesity is associated with increased surgical-site infection (SSI) following caesarean section (CS). OBJECTIVE: To summarise the evidence on the effectiveness of negative-pressure wound therapy (NPWT) for preventing SSI and other wound complications in obese women after CS. SEARCH STRATEGY: MEDLINE, Embase, CINAHL, Cochrane CENTRAL databases and ClinicalTrials.gov were systematically searched in March 2021. SELECTION CRITERIA: Randomised controlled trials (RCTs) of NPWT compared with standard dressings after CS birth. DATA COLLECTION AND ANALYSIS: Pooled effect sizes were calculated using either fixed or random effects models based on heterogeneity. The Cochrane risk of bias and Grading of Recommendations Assessment, Development and Evaluation tools were used to assess the quality of studies and overall quality of evidence. MAIN RESULTS: Ten RCTs with 5583 patients were included; studies were published between 2012 and 2021. Nine RCTs with 5529 patients were pooled for the outcome SSI. Meta-analysis results suggest a significant difference favouring the NPWT group (relative risk [RR] 0.79, 95% CI 0.65-0.95, P < 0.01), indicating an absolute risk reduction of 1.8% among those receiving NPWT compared with usual care. The risk of blistering in the NPWT group was significantly higher (RR 4.13, 95% CI 1.53-11.18, P = 0.005). All studies had high risk of bias relative to blinding of personnel/participants. Only 40% of studies reported blinding of outcome assessments and 50% had incomplete outcome data. CONCLUSIONS: The decision to use NPWT should be considered both in terms of its potential benefits and its limitations. TWEETABLE ABSTRACT: NPWT was associated with fewer SSI in women following CS birth but was not effective in reducing other wound complications.

BACKGROUND: During the last two decades, vacuum-assisted wound therapy has been successfully transferred to an endoscopic treatment approach of various upper and lower gastrointestinal leaks called endoscopic vacuum therapy (EVT). As mostly small case series are published in this field, the aim of our systematic review and meta-analysis was to evaluate the efficacy and safety of EVT in the treatment of colorectal leaks. METHODS: A systematic search of MEDLINE/PubMed and Cochrane databases was performed using search terms related to EVT and colorectal defects (anastomotic leakage, rectal stump insufficiency) according to the PRISMA guidelines. Randomized controlled trials (RCTs), observational studies, and case series published by December 2020 were eligible for inclusion. A meta-analysis was conducted on the success of EVT, stoma reversal rate after EVT as well as procedure-related complications. Statistical interferences were based on pooled estimates from random effects models using DerSimonian-Laird estimator. RESULTS: Only data from observational studies and case series were available. Twenty-four studies reporting on 690 patients with colorectal defects undergoing EVT were included. The mean rate of success was 81.4% (95% CI: 74.0%-87.1%). The proportion of diverted patients was 76.4% (95% CI: 64.9%-85.0%). The mean rate of ostomy reversal across the studies was 66.7% (95% CI: 58.0%-74.4%). Sixty-four patients were reported with EVT-associated complications, the weighted mean complication rate across the studies was 12.1% (95% CI: 9.7%-15.2%). CONCLUSIONS: Current medical evidence on EVT in patients with colorectal leaks lacks high quality data from RCTs. Based on the data available, EVT can be seen as a feasible treatment option with manageable risks for selected patients with colorectal leaks.

BACKGROUND: Postoperative reflux can compromise anastomotic healing after Ivor-Lewis oesophagectomy (ILE). We report on Pre-emptive Active Reflux Drainage (PARD) using a new double-lumen open-pore film drain (dOFD) with negative pressure to protect the anastomosis. METHODS: To prepare a dOFD, the gastric channel of a triluminal tube (Freka®Trelumina, Fresenius) is coated with a double-layered open-pore film (Suprasorb®CNP drainage film, Lohmann & Rauscher) over 25 cm. The ventilation channel is blocked. The filmcoated segment is placed in the stomach and the intestinal feeding tube in the duodenum. Negative pressure is applied with an electronic vacuum pump (- 125 mmHg, continuous suction) to the gastric channel. Depending on the findings in the endoscopic control, PARD will either be continued or terminated. RESULTS: PARD was used in 24 patients with ILE and started intraoperatively. Healing was observed in all the anastomoses. The median duration of PARD was 8 days (range 4-21). In 10 of 24 patients (40%) there were issues with anastomotic healing which we defined as "at-risk anastomosis". No additional endoscopic procedures or surgical revisions to the anastomoses were required. CONCLUSIONS: PARD with dOFD contributes to the protection of anastomosis after ILE. Negative pressure applied to the dOFD (a nasogastric tube) enables enteral nutrition to be delivered simultaneously with permanent evacuation and decompression.
