The Effect of Fascial Closure With Triclosan-Coated Sutures on the Incidence of Abdominal Wall Dehiscence: An Individual Participant Data Meta-Analysis.

Introduction: Wound closure with triclosan-coated sutures (TCS) appears to reduce the risk of surgical site infection (SSI). Because there is a strong association between postoperative SSI and the development of acute abdominal wall dehiscence (AWD) after laparotomy, we hypothesized that the use of TCS for wound closure after laparotomy may also reduce the risk of AWD. Methods: The MEDLINE, Embase, and CENTRAL databases were searched from their inception to 01 November 2022. Randomized trials that compared the use of TCS with identical but uncoated sutures for fascial closure were eligible if they could provide individual participant data (IPD) on AWD. From these trials, we only included in the analysis those subjects who underwent open abdominal surgery. The primary outcome was the incidence of AWD within 30 days postoperatively, requiring emergency reoperation. The certainty of evidence was assessed using the GRADE methodology (PROSPERO: CRD42019121173. Results: We identified twelve eligible trials. Eight studies shared IPD. The incidence of AWD within 30 days after surgery was 27/1,565 (1.7%) in the TCS group vs. 40/1,430 (2.8%) in the control group (Relative Risk: 0.70 [95% confidence interval (CI) 0.44-1.11, I 2 = 0%, τ2 = 0.00]). The certainty of evidence was moderate after downgrading for imprecision. The incidence of incisional SSI was 163/1,576 (10.3%) vs. 198/1,439 (13.8%), RR 0.80 (95% CI 0.67-0.97). Conclusion: We found no conclusive evidence to support the use of triclosan-coated sutures for the prevention of acute abdominal wall dehiscence after laparotomy. In these selected studies, a significant reduction in incisional SSI was observed.

Evaluating a novel vertical traction device for early closure in open abdomen management: a consecutive case series.

Background: In emergency surgery, managing abdominal sepsis and critically ill patients with imminent abdominal compartment syndrome (ACS) using an open abdomen (OA) approach has become standard practice for damage control. To prevent significant complications associated with OA therapy, such as abdominal infections, entero-atmospheric fistula (EAF), and abdominal wall hernia formation, early definitive fascial closure (DFC) is crucial. This study aims to assess the feasibility of a novel device designed to facilitate early fascial closure in patients with an open abdomen. Methods: Between 2019 and 2020, nine patients undergoing open abdomen management were enrolled in this study. All patients were treated using vertical mesh-mediated fascial traction combined with a novel vertical traction device (VTD). Data from these cases were collected and retrospectively analyzed. Results: In this study, all patients were treated with OA due to impending ACS. Three patients died before achieving DFC, while the remaining six patients successfully underwent DFC. The mean number of surgical procedures after OA was 3 ± 1, and the mean time to DFC was 9 ± 3 days. The use of the VTD in combination with negative pressure wound therapy (NPWT) resulted in a 76% reduction in fascia-to-fascia distance until DFC was achieved. The application of the VTD did not affect ventilation parameters or the Simplified Acute Physiology Score II (SAPS II), but intra-abdominal pressure (IAP) was reduced from 31 ± 8 mmHg prior to OA to 8.5 ± 2 mmHg after applying the device. The primary complication associated with the device was skin irritation, with three patients developing skin blisters as the most severe manifestation. Conclusion: Overall, the novel VTD appears to be a safe and feasible option for managing OA cases. It may reduce complications associated with OA by promoting early definitive fascial closure.

Case Report: Minimally invasive repair of a traumatic abdominal wall hernia in a child with a fascial closure device.

Abdominal trauma is common in daily life, but a traumatic abdominal wall hernia (TAWH) in children is rare. A TAWH is caused by a huge external force that leads to subcutaneous muscle and fascia rupture, while the skin remains intact. As abdominal pressure increases, the abdominal contents protrude, forming a lump. A TAWH is highly susceptible to missed diagnosis because of other severe injuries. We report a case of a 2-year-old boy with a TAWH who developed a prominent subcutaneous mass on the right side of his abdomen after abdominal trauma; the size of the mass changed significantly with abdominal pressure and crying. In this case, we used a new approach of laparoscopic suture repair technique with the assistance of a fascial closure device and achieved good results. We found that this method offers the advantages of minimally invasive surgery, fast recovery, and no visible surgical incisions. There was no recurrence after 8 months of follow-up.

The Open Abdomen After Intra-Abdominal Contamination in Emergency General Surgery.

INTRODUCTION: Delayed fascial closure (DFC) is an increasingly utilized technique in emergency general surgery (EGS), despite a lack of data regarding its benefits. We aimed to compare the clinical outcomes of DFC versus immediate fascial closure (IFC) in EGS patients with intra-abdominal contamination. METHODS: This retrospective study was conducted using the 2013-2020 American College of Surgeons National Surgical Quality Improvement Program database. Adult EGS patients who underwent an exploratory laparotomy with intra-abdominal contamination [wound classification III (contaminated) or IV (dirty)] were included. Patients with agreed upon indications for DFC were excluded. A propensity-matched analysis was performed. The primary outcome was 30-d mortality. RESULTS: We identified 36,974 eligible patients. 16.8% underwent DFC, of which 51.7% were female, and the median age was 64 y. After matching, there were 6213 pairs. DFC was associated with a higher risk of mortality (15.8% versus 14.2%, P = 0.016), pneumonia (11.7% versus 10.1%, P = 0.007), pulmonary embolism (1.9% versus 1.6%, P = 0.03), and longer hospital stay (11 versus 10 d, P < 0.001). No significant differences in postoperative sepsis and deep surgical site infection rates between the two groups were observed. Subgroup analyses by preoperative diagnosis (diverticulitis, perforation, and undifferentiated sepsis) showed that DFC was associated with longer hospital stay in all subgroups, with a higher mortality rate in patients with diverticulitis (8.1% versus 6.1%, P = 0.027). CONCLUSIONS: In the presence of intra-abdominal contamination, DFC is associated with longer hospital stay and higher rates of mortality and morbidity. DFC was not associated with decreased risk of infectious complications. Further studies are needed to clearly define the indications of DFC.

A descriptive analysis of skin-only closure and Bogota bag techniques for achieving complete fascial closure in damage control abdominal surgery.

BACKGROUND: Temporary abdominal closure (TAC) techniques are essential in managing open abdomen cases, particularly in damage control surgery. Skin-only closure (SC) and Bogota bag closure (BBC) are commonly used methods for TAC, but their comparative effectiveness in achieving primary fascial closure (PFC) remains unclear. The objective of this study was to evaluate the rates of PFC between patients undergoing SC and BBC techniques for TAC in peritonitis or abdominal trauma cases at a tertiary care hospital. METHODS: A retrospective cross-sectional study was conducted at the Surgical A Unit of Hayatabad Medical Complex, Peshawar, from January 2022 to July 2023. Approval was obtained from the institutional review board, and patient consent was secured for data use. Patients undergoing temporary abdominal closure using either skin-only or Bogota bag techniques were included. Exclusions comprised patients younger than 15 or older than 75 years, those with multiple abdominal wall incisions, and those with prior abdominal surgeries. Data analysis utilized SPSS version 25. The study aimed to assess outcomes following damage control surgery, focusing on primary fascial closure rates and associated factors. Closure techniques (skin-only and Bogota bag) were chosen based on institutional protocols and clinical context. Indications for damage control surgery (DCS) included traumatic and non-traumatic emergencies. Intra-abdominal pressure (IAP) was measured using standardized methods. Patients were divided into SC and BBC groups for comparison. Criteria for reoperation and primary fascial closure were established, with timing and technique determined based on clinical assessment and multidisciplinary team collaboration. The decision to leave patients open during the index operation followed damage control surgery principles. RESULTS: A total of 193 patients were included in this study, with 59.0% undergoing skin-only closure (SC) and 41.0% receiving Bogota bag closure (BBC). Patients exhibited similar demographic characteristics across cohorts, with a majority being male (73.1%) and experiencing acute abdomen of non-traumatic origin (58.0%). Among the reasons for leaving the abdomen open, severe intra-abdominal sepsis affected 51.3% of patients, while 42.0% experienced hemodynamic instability. Patients who received SC had significantly higher rates of primary fascial closure (PFC) compared to BBC (85.1% vs. 65.8%, p = 0.04), with lower rates of fascial dehiscence (1.7% vs. 7.6%, p = 0.052) and wound infections (p = 0.010). Multivariate regression analysis showed SC was associated with a higher likelihood of achieving PFC compared to BBC (adjusted OR = 1.7, 95% CI: 1.3-3.8, p < 0.05). CONCLUSION: In patients with peritonitis or abdominal trauma, SC demonstrated higher rates of PFC compared to BBC for TAC in our study population. However, further studies are warranted to validate these results and explore the long-term outcomes associated with different TAC techniques.

Modified Application of the Abdominal Re-Approximation Anchor Device in the Closure of Septic Open Abdomen in a Patient With Class III Obesity.

The Abdominal Re-Approximation Anchor (ABRA®) is a pivotal dynamic wound closure system utilized for achieving primary fascial closure in patients undergoing open abdomen surgeries. However, its efficacy can be hindered in patients with class III obesity due to anatomical complexities and compromised tissue characteristics. Here, we present the unique case of a 25-year-old woman with class III obesity (body mass index (BMI) ≥ 40 kg/m2) who required primary abdominal closure following complications of an ileostomy repair. Traditional placement of the ABRA device was not feasible due to thick subcutaneous tissue layers. Consequently, a modified application of ABRA was decided based on clinical judgment, whereby the ABRA button anchors were strategically placed internally under the subcutaneous tissue instead of externally on the skin surface. The patient completed six intraoperative tightenings of the ABRA device via this novel technique and was treated with washouts over the course of two months until complete resolution was achieved. The presented case demonstrates a successful modification of the ABRA wound closure device to suit an open abdomen patient with class III obesity.

Contemporary Abdominal Wall Reconstruction: Emerging Techniques and Trends.

Abdominal wall reconstruction is a common and necessary surgery, two factors that drive innovation. This review article examines recent developments in ventral hernia repair including primary fascial closure, mesh selection between biologic, permanent synthetic, and biosynthetic meshes, component separation, and functional abdominal wall reconstruction from a plastic surgery perspective, exploring the full range of hernia repair's own reconstructive ladder. New materials and techniques are examined to explore the ever-increasing options available to surgeons who work within the sphere of ventral hernia repair and provide updates for evolving trends in the field.

Superiority trial for the development of an ideal method for the closure of midline abdominal wall incisions to reduce the incidence of wound complications after elective gastroenterological surgery: study protocol for a randomized controlled trial.

BACKGROUND: The recent guidelines from the European and American Hernia Societies recommend a continuous small-bite suturing technique with slowly absorbable sutures for fascial closure of midline abdominal wall incisions to reduce the incidence of wound complications, especially for incisional hernia. However, this is based on low-certainty evidence. We could not find any recommendations for skin closure. The wound closure technique is an important determinant of the risk of wound complications, and a comprehensive approach to prevent wound complications should be developed. METHODS: We propose a single-institute, prospective, randomized, blinded-endpoint trial to assess the superiority of the combination of continuous suturing of the fascia without peritoneal closure and continuous suturing of the subcuticular tissue (study group) over that of interrupted suturing of the fascia together with the peritoneum and interrupted suturing of the subcuticular tissue (control group) for reducing the incidence of midline abdominal wall incision wound complications after elective gastroenterological surgery with a clean-contaminated wound. Permuted-block randomization with an allocation ratio of 1:1 and blocking will be used. We hypothesize that the study group will show a 50% reduction in the incidence of wound complications. The target number of cases is set at 284. The primary outcome is the incidence of wound complications, including incisional surgical site infection, hemorrhage, seroma, wound dehiscence within 30 days after surgery, and incisional hernia at approximately 1 year after surgery. DISCUSSION: This trial will provide initial evidence on the ideal combination of fascial and skin closure for midline abdominal wall incision to reduce the incidence of overall postoperative wound complications after gastroenterological surgery with a clean-contaminated wound. This trial is expected to generate high-quality evidence that supports the current guidelines for the closure of abdominal wall incisions from the European and American Hernia Societies and to contribute to their next updates.

Systematic review and meta-analysis comparing surgical site infection in abdominal surgery between triclosan-coated and uncoated sutures.

PURPOSE: Surgical site infection (SSI) is a frequent complication after abdominal surgery and impacts morbidity, mortality and medical costs. This systematic review evaluates whether the use of triclosan-coated sutures for closing the fascia during abdominal surgery reduces the rate of SSI compared to uncoated sutures. METHODS: A systematic review and meta-analysis were conducted using the PRISMA guidelines. On February 17, 2024, a literature search was performed in Medline ALL, Web of Science Core Collection, Cochrane Central Register of Controlled Trials and Embase. Randomized controlled trials (RCTs) on abdominal fascial closure in human adults, comparing triclosan-coated and uncoated sutures, were included. The risk of bias was assessed using the Cochrane RoB 2 tool. Pooled meta-analysis was performed using RevMan. RESULTS: Out of 1523 records, eleven RCTs were included, with a total of 10,234 patients: 5159 in the triclosan-coated group and 5075 in the uncoated group. The incidence of SSI was statistically significantly lower in the triclosan-coated group (14.8% vs. 17.3%) with an odds ratio (OR) of 0.84 (95% CI [0.75, 0.93], p = 0.001). When polydioxanone was evaluated separately (coated N = 3999, uncoated N = 3900), triclosan-coating reduced SSI; 17.5% vs. 20.1%, OR 0.86 (95% CI [0.77; 0.96], p = 0.008). When polyglactin 910 was evaluated (coated N = 1160, uncoated N = 1175), triclosan-coating reduced the incidence of SSI; 5.4% vs. 7.8%, OR 0.67 (95% CI [0.48; 0.94], p = 0.02). CONCLUSION: According to the results of this meta-analysis the use of triclosan-coated sutures for fascial closure statistically significantly reduces the incidence of SSI after abdominal surgery with a risk difference of about 2%.

Anterior versus posterior component separation technique for advanced abdominal wall reconstruction: a proposed algorithm.

OBJECTIVE: The precise indications for employing the anterior component separation technique (ACST) and the Transversus Abdominis Release (TAR) in abdominal wall reconstruction (AWR) remain uncertain, despite the undeniable value of both techniques. The aim of this study was to analyze the anterior fascial closure rate, postoperative wound morbidity, and hernia recurrence rate for both procedures according to the algorithm used for complex AWR. METHODS: A retrospective analysis of prospectively collected data was carried out. Patients undergoing AWR for midline incisional hernias using either open or endoscopic ACST (E-ACST) or TAR between March 2013 and August 2022 were included. Patients with lateral hernia components were excluded. The surgical technique was depending on the pre- and intraoperative findings regarding hernia width and on the estimated traction to achieve anterior fascial closure (see algorithm). Initially, intermediate hernia defects ranging from approximately 10-14 cm in width were repaired using E-ACST. However, as the study advanced, TAR became the preferred method for addressing these types of defects. Open ACST was consistently employed for defects wider than 14-15 cm throughout the entire study duration. Outcomes of interest were anterior fascial closure, surgical site occurrences, and hernia recurrence rate. Follow-up was performed at 1 month, 1 year, and 2 years. RESULTS: A total of 119 patients underwent AWR with CST: 63 patients (52.9%) were included in the ACST group and 56 patients (47.1%) in the TAR group. No significant differences were observed in patient and hernia characteristics. The use of botulinum toxin A (BTA) injection and preoperative progressive pneumoperitoneum (PPP) was more frequently used in the ACST group (BTA 19.0%, PPP 15.9% versus BTA 5.4%, PPP 1.8% for TAR patients). Anterior fascial closure was achieved in 95.2% of the ACST group and 98.2% of the TAR group (p = 0.369). The TAR group demonstrated a significantly lower SSO rate at one month (44.3% versus 14.3%, p < 0.001) and required fewer procedural interventions (SSO-PI) (31.1% versus 8.9%, p = 0.003). The recurrence rate at one year was low and there was no statistically significant difference between the two groups (ACST 1.8% vs TAR 4.5%, p = 0.422). CONCLUSION: Following a proposed algorithm, the anterior fascial closure rate was high and similar for both techniques. As postoperative wound morbidity is significantly increased after ACST, our findings support recommending TAR for defects up to 14 cm in width, while favoring open ACST for larger defects.

Small bites versus large bites during fascial closure of midline laparotomies: a systematic review and meta-analysis.

PURPOSE: Incisional ventral hernias (IVH) are common after laparotomies, with up to 20% incidence in 12 months, increasing up to 60% at 3-5 years. Although Small Bites (SB) is the standard technique for fascial closure in laparotomies, its adoption in the United States is limited, and Large Bites (LB) is still commonly performed. We aim to assess the effectiveness of SB regarding IVH. METHODS: We searched for RCTs and observational studies on Cochrane, EMBASE, and PubMed from inception to May 2023. We selected patients ≥ 18 years old, undergoing midline laparotomies, comparing SB and LB for IVH, surgical site infections (SSI), fascial dehiscence, hospital stay, and closure duration. We used RevMan 5.4. and RStudio for statistics. Heterogeneity was assessed with I2 statistics, and random effect was used if I2 > 25%. RESULTS: 1687 studies were screened, 45 reviewed, and 6 studies selected, including 3 RCTs and 3351 patients (49% received SB and 51% LB). SB showed fewer IVH (RR 0.54; 95% CI 0.39-0.74; P < 0.001) and SSI (RR 0.68; 95% CI 0.53-0.86; P = 0.002), shorter hospital stay (MD -1.36 days; 95% CI -2.35, -0.38; P = 0.007), and longer closure duration (MD 4.78 min; 95% CI 3.21-6.35; P < 0.001). No differences were seen regarding fascial dehiscence. CONCLUSION: SB technique has lower incidence of IVH at 1-year follow-up, less SSI, shorter hospital stay, and longer fascial closure duration when compared to the LB. SB should be the technique of choice during midline laparotomies.

The 6:1 short stitch SL-WL-ratio: short term closure results of transverse and midline incisions in elective and emergency operations.

AIM: To analyze laparotomy closure quality (suture/wound length ratio; SL/WL) and short term complications (surgical site occurrence; SSO) of conventional midline and transverse abdominal incisions in elective and emergency laparotomies with a longterm, absorbent, elastic suture material. METHOD: Prospective, monocentric, non-randomized, controlled cohort study on short stitches with a longterm resorbable, elastic suture (poly-4-hydroxybutyrate, [p-4OHB]) aiming at a 6:1 SL/WL-ratio in midline and transverse, primary and secondary laparotomies for elective and emergency surgeries. RESULTS: We included 351 patients (♂: 208; ♀: 143) with midline (n = 194), transverse (n = 103), and a combined midline/transverse L-shaped (n = 54) incisions. There was no quality difference in short stitches between elective (n = 296) and emergency (n = 55) operations. Average SL/WL-ratio was significantly higher for midline than transverse incisions (6.62 ± 2.5 vs 4.3 ± 1.51, p < 0.001). Results in the first 150 patients showed a reduced SL/WL-ratio to the following 200 suture closures (SL/WL-ratio: 5.64 ± 2.5 vs 6.1 ± 2.3; p < 0.001). SL/WL-ratio varied insignificantly among the six surgeons participating while results were steadily improving over time. Clinically, superficial surgical site infections (SSI, CDC-A1/2) were encountered in 8%, while 4,3% were related to intraabdominal complications (CDC-A3). An abdominal wall dehiscence (AWD) occurred in 22/351 patients (6,3%)-twice as common in emergency than elective surgery (12,7 vs 5,1%)-necessitating an abdominal revision in 86,3% of cases. CONCLUSION: We could show that a short stitch 6:1 SL/WL-ratio with a 2-0 single, ultra-long term, absorbent, elastic suture material can be performed in only 43% of cases (85% > 4:1 SL/WL-ratio), significantly better in midline than transverse incisions. Transverse incisions should preferably be closed in two layers to achieve a sufficient SL/WL-ratio equivalent to the median incision. GOV IDENTIFIER: NCT01938222.

The effectiveness of fascial closure with antimicrobial-coated sutures in preventing incisional surgical site infections in gastrointestinal surgery: a systematic review and meta-analysis.

The aim of this study was to conduct a systematic review and meta-analysis of the efficacy of fascial closure using antimicrobial-sutures specifically for the prevention of surgical site infections (SSIs) in gastrointestinal surgery, as part of the revision of the SSI prevention guidelines of the Japanese Society of Surgical Infectious Diseases (JSSI). We searched CENTRAL, PubMed and ICHUSHI-Web in May 2023, and included randomized controlled trials (RCTs) comparing antimicrobial-coated and non-coated sutures for fascial closure in gastrointestinal surgery (PROSPERO No. CRD42023430377). Three authors independently screened the RCTs. We assessed the risk of bias and the GRADE criteria for the extracted data. The primary outcome was incisional SSI and the secondary outcomes were abdominal wall dehiscence and the length of postoperative hospital stay. This study was supported partially by the JSSI. A total of 10 RCTs and 5396 patients were included. The use of antimicrobial-coated sutures significantly lowered the risk of incisional SSIs compared with non-coated suture (risk ratio: 0.79, 95% confidence intervals: 0.64-0.98). In subgroup analyses, antimicrobial-coated sutures reduced the risk of SSIs for open surgeries, and when monofilament sutures were used. Antimicrobial-coated sutures did not reduce the incidence of abdominal wall dehiscence and the length of hospital stay compared with non-coated sutures. The certainty of the evidence was rated as moderate according to the GRADE criteria, because of risk of bias. In conclusion, the use of antimicrobial-coated sutures for fascial closure in gastrointestinal surgery is associated with a significantly lower risk of SSI than non-coated sutures.

Damage Control Surgery and Transfer in Emergency General Surgery.

Selective non traumatic emergency surgery patients are targets for damage control surgery (DCS) to prevent or treat abdominal compartment syndrome and the lethal triad. However, DCS is still a subject of controversy. As a concept, DCS describes a series of abbreviated surgical procedures to allow rapid source control of hemorrhage and contamination in patients with circulatory shock to allow resuscitation and stabilization in the intensive care unit followed by delayed return to the operating room for definitive surgical management once the patient becomes physiologic stable. If appropriately applied, the DCS morbidity and mortality can be significantly reduced.

The impact of hypertonic saline on damage control laparotomy after penetrating abdominal trauma.

PURPOSE: The inability to achieve primary fascial closure (PFC) after emergency laparotomy increases the rates of adverse outcomes including fistula formation, incisional hernia, and intraabdominal infection. Hypertonic saline (HTS) infusion improves early PFC rates and decreases time to PFC in patients undergoing damage control laparotomy (DCL) after injury. We hypothesized that in patients undergoing DCL after penetrating abdominal injury, HTS infusion would decrease the time to fascial closure as well as the volume of crystalloid required for resuscitation without inducing clinically relevant acute kidney injury (AKI) or electrolyte derangements. METHODS: We retrospectively analyzed all penetrating abdominal injury patients undergoing DCL within the University of Pennsylvania Health System (January 2015-December 2018). We compared patients who received 3% HTS at 30 mL/h (HTS) to those receiving isotonic fluid (ISO) for resuscitation while the abdominal fascia remained open. Primary outcomes were the rate of early PFC (PFC within 72 h) and time to PFC; secondary outcomes included acute kidney injury, sodium derangement, ventilator-free days, hospital length of stay (LOS), and ICU LOS. Intergroup comparisons occurred by ANOVA and Tukey's comparison, and student's t, and Fischer's exact tests, as appropriate. A Shapiro-Wilk test was performed to determine normality of distribution. RESULTS: Fifty-seven patients underwent DCL after penetrating abdominal injury (ISO n = 41, HTS n = 16). There were no significant intergroup differences in baseline characteristics or injury severity score. Mean time to fascial closure was significantly shorter in HTS (36.37 h ± 14.21 vs 59.05 h ± 50.75, p = 0.02), and the PFC rate was significantly higher in HTS (100% vs 73%, p = 0.01). Mean 24-h fluid and 48-h fluid totals were significantly less in HTS versus ISO (24 h: 5.2L ± 1.7 vs 8.6L ± 2.2, p = 0.01; 48 h: 1.3L ± 1.1 vs 2.6L ± 2.2, p = 0.008). During the first 72 h, peak sodium (Na) concentration (146.2 mEq/L ± 2.94 vs 142.8 mEq/L ± 3.67, p = 0.0017) as well as change in Na from ICU admission (5.1 mEq/L vs 2.3, p = 0.016) were significantly higher in HTS compared to ISO. Patients in the HTS group received significantly more blood in the trauma bay compared to ISO. There were no intergroup differences in intraoperative blood transfusion volume, AKI incidence, change in chloride concentration (△Cl) from ICU admit, Na to Cl gradient (Na:Cl), initial serum creatinine (Cr), peak post-operative Cr, change in creatinine concentration (△Cr) from ICU admission, creatinine clearance (CrCl), initial serum potassium (K), peak ICU K, change in K from ICU admission, initial pH, highest or lowest post-operative pH, mean hospital LOS, ICU LOS, and ventilator-free days. CONCLUSIONS: HTS infusion in patients undergoing DCL after penetrating abdominal injury decreases the time to fascial closure and led to 100% early PFC. HTS infusion also decreased resuscitative fluid volume without causing significant AKI or electrolyte derangement. HTS appears to offer a safe and effective fluid management approach in patients who sustain penetrating abdominal injury and DCL to support early PFC without inducing measurable harm. LEVEL OF EVIDENCE: Level III.

Hernia Prevention: The Role of Technique and Prophylactic Mesh to Prevent Incisional Hernias.

Millions of laparotomies are performed annually, carrying up to a 41% risk of developing into a hernia. Incisional hernias are associated with morbidity, mortality, and costs; an estimated $9.6 billion is spent annually on repair of ventral hernias. Although repair is possible, surgeons must prevent incisional hernias from occurring. There is substantial evidence on surgical technique to reduce the risk of incisional hernia formation. This article aims to critically summarize the use of surgical technique and prophylactic mesh augmentation during fascial closure to inform decision-making and reduce incisional hernia formation.

Fascial Defect Closure During Ventral Hernia Repair: A Systematic Review of Randomized Controlled Trials.

Background: During minimally invasive ventral hernia repair (VHR) it is unknown if a fascial defect closure, as opposed to a bridged repair (current care), is beneficial for patients. We sought to systematically review the published literature on the role of fascial defect closure during minimally invasive VHR. Methods: PubMed, Embase, Scopus, Cochrane, and Clinicaltrials.gov were reviewed for randomized controlled trials (RCTs) that compared fascial defect closure with bridged repair. The primary outcome was major complications defined as deep/organ-space surgical site infections (SSIs), reoperations, hernia recurrences, or deaths. Secondary outcomes included SSI, seroma, eventration, hernia recurrence, post-operative pain, and quality of life (QOL). Pooled risk ratios with 95% confidence intervals were obtained through random effect meta-analyses. Results: Of 579 screened articles, 6 publications of 5 RCTs were included. No significant difference in major complications (10.6% vs 10.4%, RR=1.05, 95% CI=0.51-2.14, P=.90) or recurrences (9.0% vs 10.6%, RR=0.92, 95% CI=0.32-2.61, P=.87) were found between groups. Fascial defect closure decreased the risk of seromas (22.9% vs 34.2%, RR=0.60, 95% CI=0.37-0.97, P=.04) and may decrease the risk of eventrations (6.7% vs 9.0%, RR=0.74, 95% CI=0.37-1.50, P=.41) at the expense of potentially increasing the risk of SSI (3.2% vs 1.4%, RR=1.89, 95% CI=0.60-5.93; P=.28). Reporting of pain and QOL scores was inconsistent. Conclusion: While most individual RCTs demonstrated benefit with fascial defect closure during minimally invasive VHR, our meta-analysis of fascial defect closure demonstrated only a statistically significant difference in seromas compared to bridged repair. Large, multi-center RCTs are needed.

National Open Abdomen Audit (NOAA) - protocol for an observational audit of the use and management of the open abdomen in secondary care across Great Britain and Ireland.

AIM: Use of open abdomen (OA) remains an important life-saving manoeuvre in the management of trauma and the abdominal catastrophe. The National Open Abdomen Audit (NOAA) is an audit project investigating the indications, management, and subsequent outcomes of OA treatment throughout the UK. The aim is to generate a snapshot of practice which will inform the management of future patients and potentially reduce the significant harm that can be associated with OA. METHODS AND ANALYSIS: NOAA is a collaborative, prospective observational audit recruiting patients from across Great Britain and Ireland. The study will open from July 2023 with rolling recruitment across participating sites. All adult patients who leave theatre with an OA will be included and followed-up for 90 days. The primary objective is to prospectively audit the national variability in the management of the OA. Secondary outcomes include the treatment modality used for OA, indication, outcome of treatment and complications, including mortality and development of intestinal failure. All data will be recorded and managed using the secure REDCap electronic data capture and analysed using Stata (version 16.1). Results will be reported in accordance with the STROBE statement. CONCLUSION: Results will be used to formulate a practical clinical guideline on when to implement an OA along with a stepwise management plan once initiated to reduce the associated morbidity and mortality. It is hoped that participation in this study will facilitate education of surgeons with a "trickle down" effect on all members of the surgical team and remove variability in the management.

Surgeon perspectives on the STITCH trial: a mixed methods study.

BACKGROUND: Incisional hernia prevention strategies related to fascial closure technique during laparotomy are well described yet poorly implemented in practice. The factors hindering the surgeon's adoption of evidence-based techniques for fascial closure are poorly understood and characterized. METHODS: Using an exploratory sequential mixed methods design, we first collected 139 responses to a validated quantitative survey based on a Theoretical Domain Framework for adoption of healthcare practices. Mean scores from survey responses were tabulated, and the findings were used to develop an interview guide for subsequent qualitative individual semi-structured phone interviews. Fourteen practicing surgeons were purposively sampled from social media outlets and our institution. The interviews were recorded and transcribed verbatim for coding and thematic analysis using NVivo 12 Plus. Data from the surveys and interviews were integrated using joint displays. RESULTS: Quantitative and qualitative analyses from surveys and semi-structured interviews revealed various themes related to surgeon decision-making related to fascial closure technique. Surgeons cited limitations of prior studies, applicability of findings, anecdotal experiences, and situation-specific environments that influence their decision-making. Peer influence and lack of training also affected surgeons' perspectives on integrating small bite technique into practice. CONCLUSION: Trial design limitations, peer influence, and patient-specific factors impacted surgeon decision-making in the choice of fascial closure technique. Future clinical trials in diverse patient populations may improve surgeons' confidence in implementing technique for fascial closure.

Cierre dinámico y toxina botulínica: una alternativa novedosa para el cierre definitivo del abdomen abierto y contenido / Dynamic closure system and botulinum toxin: a novel alternative for definitive closure of open abdomen

RESUMEN Se presenta el caso de un paciente masculino de 54 años que, cursando internación por neumonía- COVID-19, intercurrió con shock séptico por diverticulitis aguda Hinchey IV, por lo que se realizó cirugía de Hartmann. Evolucionó con isquemia colónica, se realizó colectomía total y abdomen abierto y contenido (AAyC). El manejo del AAyC se realizó con sistema de vacío (VAC) durante 7 semanas, resultando un AAyC tipo IIIa (Björck) con un gap de 16 cm. Se decidió iniciar, una vez dadas las condiciones clínicas del paciente, el cierre dinámico (CD) con tracción fascial con malla de polipropileno asociado a inyección de toxina botulínica (TB). Esta estrategia permitió el cierre fascial primario (CFP) de la pared abdominal en la quinta semana de comenzado el tratamiento, evitando de esta manera la morbilidad de un cierre por segunda intención.

ABSTRACT We report the case of a 54-year-old male patient hospitalized for COVID-19 pneumonia who developed septic shock due to acute Hinchey IV diverticulitis and required Hartmann's surgery. The patient evolved with colonic ischemia and underwent total colectomy and open abdomen (OA) with temporary abdominal closure (TAC) that was managed with a vacuum-assisted wound closure (VAWC) system for 7 weeks, resulting in a Björck grade 3A OA with a 16-cm gap. As he had a favorable clinic course, dynamic closure with mesh-mediated fascial traction was decided, associated with botulinum toxin (BT) injection. This strategy allowed primary fascial closure (PFC) of the abdominal wall 5 weeks after treatment was initiated, thus avoiding the complications of healing by secondary intention.
