Abstract
BACKGROUND Guidelines recommend biologic prosthetics for ventral hernia repair (VHR) in contaminated fields, yet long-term and patient-reported data are limited. We aimed to determine the long-term rate of hernia recurrence, and other clinical and patient-reported outcomes following the use of porcine small intestine submucosa (PSIS) for VHR in a contaminated field. METHODS Consecutive patients undergoing open VHR with PSIS mesh in a contaminated field from 2004 to 2014 were prospectively evaluated for hernia recurrence and other post-operative complications. Multivariate logistic and Cox regression analyses identified predictors of hernia recurrence and surgical site infection. Patient-reported outcomes were evaluated using SF-36, Hernia-Related Quality-of-Life Survey (HerQLes) and Body Image Questionnaire instruments. RESULTS Forty-six hernias were repaired in clean-contaminated [16 (35 %)], contaminated [11 (24 %)] and dirty [19 (41 %)] fields. Median follow-up was 47 months [interquartile range: 31-79] and all patients had greater than 12-month follow-up. Sixteen patients (35 %) were not re-examined. Incidence of surgical site events and surgical site infection were 43 % (n = 20) and 56 % (n = 25), respectively. American Society of Anesthesiologists score 3 or greater was an independent predictor of surgical site infection (odds ratio 5.34 [95 % confidence interval 1.01-41.80], p = 0.04). Hernia recurrence occurred in 61 % (n = 28) with a median time to diagnosis of 16 months [interquartile range 8-26]. After bridged repair, 16 of 18 patients (89 %) recurred, compared to 12 of 28 (43 %) when fascia was approximated (p < 0.01). Bridged repair was an independent predictor of recurrence (odds ratio 10.67 [95 % confidence interval 2.42-76.08], p < 0.01). Patients with recurrences had significantly worse scores on the SF-36 mental health component and self-perceived body image, whereas HerQLes scores were similar. CONCLUSIONS Hernia recurrences and wound infections are high with the use of biologic PSIS mesh in contaminated surgical fields. Careful consideration is warranted using this approach.

Bone Marrow-Derived Mesenchymal Stem Cells Enhance Bacterial Clearance and Preserve Bioprosthetic Integrity in a Model of Mesh Infection. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2016; 4:e751. [PMID: 27482490 PMCID: PMC4956863 DOI: 10.1097/gox.0000000000000765] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2016] [Accepted: 04/20/2016] [Indexed: 12/27/2022]
Abstract
Background: The reported incidence of mesh infection in contaminated operative fields is as high as 30% regardless of the material used. Recently, mesenchymal stem cells (MSCs) have been shown to possess favorable immunomodulatory properties and improve tissue incorporation when seeded onto bioprosthetics. The aim of this study was to evaluate whether seeding noncrosslinked bovine pericardium (Veritas Collagen Matrix) with allogeneic bone marrow–derived MSCs improves infection resistance in vivo after inoculation with Escherichia coli (E. coli). Methods: Rat bone marrow–derived MSCs at passage 3 were seeded onto bovine pericardium and cultured for 7 days before implantation. Additional rats (n = 24) were implanted subcutaneously with MSC-seeded or unseeded mesh and inoculated with 7 × 105 colony-forming units of E. coli or saline before wound closure (group 1, unseeded mesh/saline; group 2, unseeded mesh/E. coli; group 3, MSC-seeded mesh/E. coli; 8 rats per group). Meshes were explanted at 4 weeks and underwent microbiologic and histologic analyses. Results: MSC-seeded meshes inoculated with E. coli demonstrated superior bacterial clearance and preservation of mesh integrity compared with E. coli–inoculated unseeded meshes (87.5% versus 0% clearance; p = 0.001). Complete mesh degradation concurrent with abscess formation was observed in 100% of rats in the unseeded/E. coli group, which is in contrast to 12.5% of rats in the MSC-seeded/E. coli group. Histologic evaluation determined that remodeling characteristics of E. coli–inoculated MSC-seeded meshes were similar to those of uninfected meshes 4 weeks after implantation. Conclusions: Augmenting a bioprosthetic material with stem cells seems to markedly enhance resistance to bacterial infection in vivo and preserve mesh integrity.

A Cost-Utility Assessment of Mesh Selection in Clean-Contaminated Ventral Hernia Repair. Plast Reconstr Surg 2016; 137:647-659.

Abstract
BACKGROUND Mesh reinforcement can reduce hernia recurrence, but mesh selection is poorly understood, particularly in contaminated defects. Acellular dermal matrix has enabled single-stage ventral hernia repair in clean-contaminated wounds but can be associated with higher complications and cost compared with synthetic mesh. This study evaluated the cost-utility of synthetic mesh and acellular dermal matrix for clean-contaminated ventral hernia repairs. METHODS A systematic review of articles comparing outcomes for synthetic and acellular dermal matrix repairs identified 14 ventral hernia repair-specific health states. Quality-adjusted life years were determined through Web-based visual analog scale survey of 300 nationally representative individuals. Overall expected cost and quality-adjusted life-years for ventral hernia repair were assessed using a Monte Carlo simulation with sensitivity analyses. RESULTS Synthetic mesh reinforcement had an expected cost of $15,776 and quality-adjusted life-year value gained of 21.03. Biological mesh had an expected cost of $23,844 and quality-adjusted life-year value gained of 20.94. When referencing a common baseline (do nothing), acellular dermal matrix (incremental cost-effectiveness ratio, 3378 ($/quality-adjusted life years)) and synthetic mesh (incremental cost-effectiveness ratio, 2208 ($/quality-adjusted life years)) were judged cost-effective, although synthetic mesh was more strongly favored. Monte Carlo sensitivity analysis demonstrated that synthetic mesh was the preferred and most cost-effective strategy in 94 percent of simulations, supporting its overall greater cost-utility. Despite varying the willingness-to-pay threshold from $0 to $100,000 per quality-adjusted life-year, synthetic mesh remained the optimal strategy across all thresholds in sensitivity analysis. CONCLUSION This cost-utility analysis suggests that synthetic mesh repair of clean-contaminated hernia defects is more cost-effective than acellular dermal matrix.

Abstract
Intestinal failure (IF) is a debilitating condition of inadequate nutrition due to an anatomical and/or physiological deficit of the intestine. Surgical management of patients with acute and chronic IF requires expertise to deal with technical challenges and make correct decisions. Dedicated IF units have expertise in patient selection, operative risk assessment and multidisciplinary support such as nutritional input and interventional radiology, which dramatically improve the morbidity and mortality of this complex condition and can beneficially affect the continuing dependence on parenteral nutritional support. Currently there is little guidance to bridge the gap between general surgeons and specialist IF surgeons. Fifteen European experts took part in a consensus process to develop guidance to support surgeons in the management of patients with IF. Based on a systematic literature review, statements were prepared for a modified Delphi process. The evidence for each statement was graded using Oxford Centre for Evidence-Based Medicine Levels of Evidence. The current paper contains the statements reflecting the position and practice of leading European experts in IF encompassing the general definition of IF surgery and organization of an IF unit, strategies to prevent IF, management of acute IF, management of wound, fistula and stoma, rehabilitation, intestinal and abdominal reconstruction, criteria for referral to a specialist unit and intestinal transplantation.

Abstract
Ventral hernia repair (VHR) in patients with inflammatory bowel disease (IBD) presents unique surgical challenges including impaired wound healing, concomitant intestinal operations, along with likely future abdominal surgeries. Appropriate techniques and mesh choices in these patients remain under active debate. Herein we report our experience with using a retromuscular approach for major VHR in a consecutive cohort of IBD patients. We identified all patients with IBD undergoing open VHR with retrorectus mesh placement between 2007 and 2013 in our prospectively maintained database. Main outcomes included patient and hernia characteristics, perioperative details, wound complications, and hernia recurrence. A total of 38 patients with IBD met inclusion criteria. Mean hernia defect size was 338 cm2. Synthetic mesh was used in 16 patients and biologic mesh was used in 22 of patients. A surgical site occurrence (SSO) occurred in 13 (34.2%) patients, 7 (18.4%) of which were surgical site infections (SSIs). There were no instances of postoperative intestinal complications or enterocutaneous fistulae. At the mean follow-up 37 months, there were 3 (9.4%) recurrences. Our retromuscular repairs were associated with a low rate of wound morbidity and no intestinal complications. Furthermore, we report a relatively low rate of recurrences, especially in this series of complex multiply recurrent hernias. Overall, our retromuscular approach seems to be safe and effective in hernia patients with IBD.

Abstract
BACKGROUND Ileostomy reversals are commonly performed procedures after colon and rectal operations. Laparoscopic ileostomy reversal (LIR) with lysis of adhesions has potential benefits over conventional open surgery. The aim of this study was to compare outcomes of laparoscopic and open ileostomy reversal. METHODS 133 consecutive patients undergoing ileostomy reversal at our institution between June 2009 and August 2013 were analyzed using a retrospective database. The group comprised 53 laparoscopic cases and 80 open cases, performed by four surgeons at a single center. The data were analyzed for patient demographics, operative characteristics, postoperative outcomes, and 30-day morbidity and mortality. RESULTS The two groups had comparable mean age, gender distribution, ASA scores, and BMI. The laparoscopic group had a significantly longer duration of surgery compared to the open reversal group (109 versus 93 min, p < 0.05). However, this group underwent more lysis of adhesions (60.4 % versus 26.3 %, p < 0.01) as well as concurrent stoma site mesh reinforcement (32.1 % versus 6.3 %, p < 0.01). In the laparoscopy group, 20.7 % of patients underwent intra-corporeal ileo-ileal anastomosis. There were no significant differences between the laparoscopic and open groups with regard to estimated blood loss (31 versus 40 ml, respectively) or mean length of stay (5.3 vs. 5.7 days, respectively). The rates of overall 30-day morbidity (16.9 % for laparoscopic vs. 21.3 % for open) as well as rates of specific complications were equivalent between groups. 30-day mortalities were not noted in either group. CONCLUSION LIR is safe and effective with low perioperative morbidity and mortality. The use of laparoscopy as an option in terms of concomitant hernia repair and lysis of adhesions may be considered in selected patients.

Abstract
BACKGROUND Few studies predict which patients have dissolution of their postoperative discomfort or develop chronic pain after ventral hernia repair (VHR). This study develops a predictive model to determine which patients are at the greatest risk of chronic pain after VHR. METHODS A prospective study of VHR patients was performed via the International Hernia Mesh Registry. Anonymous, self-reported, quality of life data using the Carolinas Comfort Scale (CCS) was recorded preoperatively, and 1,6, and 12 months postoperatively. Pain was identified as a score of 2 or more (mild but bothersome to severe) for any Carolinas Comfort Scale pain-specific questions. Logistic regression analyses were performed to determine statistically significant predictors of chronic pain. Univariate analysis selected potential predictors with a P value less than .15, and a subsequent multivariable model was built using backward elimination setting retention criterion at P < .15. Goodness-of-fit of the model was tested using Hosmer-Lemeshow test. A value of greater than 70% for the area under the curve (AUC) was considered most accurate diagnostically. The final model was then internally validated with bootstrap analysis. RESULTS A total of 887 patients underwent VHR between 2007 and 2014. The patients had an average age of 57.2 ± 12.8 years, 52.4% were female, 17.0% were active smokers, and 13.2% used narcotics preoperatively. With 74% follow-up at 1 year, 26.0% of the patients reported chronic discomfort. After logistic regression model, independent predictors of pain at 6 months were preoperative pain score 2 or more (P < .0001), preoperative narcotic use (P = .06), and 1-month postoperative pain score 2 or more (P < .0001), AUC = .74. Baseline, 1-month, and 6-month predictors determined the final multivariate regression model for prediction of chronic pain at 1 year, AUC = .73. Older age was protective against chronic pain (odds ratio [OR] .98, 95%confidence interval [CI] = .96 to .998, P = .03), female sex increased risk with an OR of 1.7(CI = 1.1 to 2.7, P = .02); preoperative pain, and recurrent hernia repair nearly doubled the risk of developing chronic pain postoperatively (OR = 3.0, CI = 1.8 to 4.8, P < .0001 and 1.6, CI = .98 to 2.6, P = .06, respectively). Importantly, presence of pain at 1 month was a strong predictor of chronic pain at 1-year follow-up (OR = 2.6, CI = 1.7 to 4.2, P < .0001). CONCLUSIONS Patients who have preoperative pain and at 1 month postoperatively are significantly more likely to have chronic pain. Both short- and long-term pain can be predicted from female sex, younger age, and repair of recurrent hernias. This predictive model may aid in preoperative counseling and when considering postoperative intervention for pain management in VHR patients.

Abstract
INTRODUCTION Traumatic abdominal wall hernia is a rare but serious diagnosis resulting from blunt abdominal trauma. The clinical diagnosis is not usually straightforward and the hernia is often discovered at the time of the surgical exploration for intra-abdominal injuries or by imaging studies. PRESENTATION OF CASE A 25-year-old obese, restraint, male patient was the victim of a high-speed road traffic accident. Among other injuries, he showed extensive skin maceration and bruising over the lower abdomen and flanks upon presentation, however he did not need any surgical intervention. Contrast-enhanced computed tomography scan of the abdomen and pelvis demonstrated extensive abdominal wall muscular disruption over both flanks with herniation of the right colon. Counselled to follow up in 4-6 weeks to have the hernia surgically repaired, he showed up after 8 months with a large muscular defect resulting in a large hernia containing small and large bowel loops. DISCUSSION The timing and type of the surgical repair of traumatic abdominal wall hernia depends upon the size of the hernia defect and the presence of associated intra-abdominal injuries. Delayed repair; however, may result in a large defect making primary, non-prosthetic repair impossible and increases the risk of abdominal compartment syndrome after surgical correction. CONCLUSION Traumatic abdominal wall hernia presents a diagnostic as well as a therapeutic challenge. The therapeutic approach is governed by a multitude of factors emphasizing the need of a patient-tailored, case by case management plan.

Abstract
BACKGROUND Repair of grade 3 and grade 4 ventral hernias is a distinct challenge, given the potential for infection, and the comorbid nature of the patient population. This study evaluates our institutional outcomes when performing single-stage repair of these hernias, with biologic mesh for abdominal wall reinforcement. METHODS A prospectively maintained database was reviewed for all patients undergoing repair of grade 3 (potentially contaminated) or grade 4 (infected) hernias, as classified by the Ventral Hernia Working Group. All those patients undergoing repair with component separation techniques and biologic mesh reinforcement were included. Patient demographics, comorbidities, and postoperative complications were analyzed. Univariate analysis was performed to define factors predictive of hernia recurrence and wound complications. RESULTS A total of 41 patients underwent single-stage repair of grade 3 and grade 4 hernias during a 4-year period. The overall postoperative wound infection rate was 15%, and hernia recurrence rate was 12%. Almost all recurrences were seen in grade 4 hernia repairs, and in those patients undergoing bridging repair of the hernia. One patient required removal of the biologic mesh. Those factors predicting hernia recurrence were smoking (P = 0.023), increasing body mass index (P = 0.012), increasing defect size (P = 0.010), and bridging repair (P = 0.042). No mesh was removed due to perioperative infection. Mean follow-up time for this patient population was 25 months. CONCLUSIONS Single-stage repair of grade 3 hernias performed with component separation and biologic mesh reinforcement is effective and offers a low recurrence rate. Furthermore, the use of biologic mesh allows for avoidance of mesh explantation in instances of wound breakdown or infection. Bridging repairs are associated with a high recurrence rate, as is single-stage repair of grade 4 hernias.

Cost of ventral hernia repair using biologic or synthetic mesh. J Surg Res 2016; 203:459-65.

Abstract
BACKGROUND Patients undergoing ventral hernia repair (VHR) with biologic mesh (BioM) have higher hospital costs compared with synthetic mesh (SynM). This study compares 90-d pre- and post-VHR hospital costs (180-d) among BioM and SynM based on infection risk. METHODS This retrospective National Surgical Quality Improvement Program study matched patient perioperative risk with resource utilization cost for a consecutive series of VHR repairs. Patient infection risks, clinical and financial outcomes were compared in unmatched SynM (n = 303) and BioM (n = 72) groups. Propensity scores were used to match 35 SynM and BioM pairs of cases with similar infection risk for outcomes analysis. RESULTS BioM patients in the unmatched group were older with higher American Society of Anesthesiologists (ASA) and wound classification, and they more frequently underwent open repairs for recurrent hernias. Wound surgical site infections were more frequent in unmatched BioM patients (P = 0.001) as were 180-d costs ($43.8k versus $14.0k, P < 0.001). Propensity matching resulted in 31 clean cases. In these low-risk patients, wound occurrences and readmissions were identical, but 180-d costs remained higher ($31.8k versus $15.5k, P < 0.001). There were no differences in hospital 180-d diagnostic, emergency room, intensive care unit, floor, pharmacy, or therapeutic costs. However, 180-d operating room services and supply costs were higher in the BioM group ($21.1k versus $7.1k, P < 0.001). CONCLUSIONS BioM is used more commonly in hernia repairs involving higher wound class and ASA scores and recurrent hernias. Clinical outcomes after low-risk VHRs are similar; SynM utilization in low-risk hernia repairs was more cost-effective.

Abstract
INTRODUCTION Although recently published guidelines recommend against the use of synthetic non-absorbable materials in cases of potentially contaminated or contaminated surgical fields due to the increased risk of infection (1, 2), the use of bio-prosthetic meshes for abdominal wall or ventral hernia repair is still controversially discussed in such cases. Bio-prosthetic meshes have been recommended due to less susceptibility for infection and the decreased risk of subsequent mesh explantation. The purpose of this review is to elucidate if there are any indications for the use of biological and biosynthetic meshes in incarcerated abdominal wall hernias based on the recently published literature. METHODS A literature search of the Medline database using the PubMed search engine, using the keywords returned 486 articles up to June 2015. The full text of 486 articles was assessed and 13 relevant papers were identified including 5 retrospective case cohort studies, 2 case-controlled studies, and 6 case series. RESULTS The results of Franklin et al. (3-5) included the highest number of biological mesh repairs (Surgisis(®)) by laparoscopic IPOM in infected fields, which demonstrated a very low incidence of infection and recurrence (0.7 and 5.2%). Han et al. (6) reported in his retrospective study, the highest number of treated patients due to incarcerated hernias by open approach using acellular dermal matrix (ADM(®)) with very low rate of infection as well as recurrences (1.6 and 15.9%). Both studies achieved acceptable outcome in a follow-up of at least 3.5 years compared to the use of synthetic mesh in this high-risk population (7). CONCLUSION Currently, there is a very limited evidence for the use of biological and biosynthetic meshes in strangulated hernias in either open or laparo-endoscopic repair. Finally, there is an urgent need to start with randomized controlled comparative trials as well as to support registries with data to achieve more knowledge for tailored indication for the use of biological meshes.

Abstract
INTRODUCTION The management of chronic mesh infection is challenging and controversial. The use of synthetic material to repair the abdominal wall in the infected setting is not recommended, especially in the presence of active infection caused by Staphylococcus aureus. METHODS This is a prospective observational study designed to evaluate the outcomes in patients with active mesh infection caused by Staphylococcus aureus. Patients underwent simultaneous removal and replacement of polypropylene mesh. The treatment protocol included the complete removal of infected mesh, followed by the anatomical reconstruction, and reinforcement of the abdominal wall using a new onlay polypropylene mesh. Early and late wound complications, medical complications, and hernia recurrences were analyzed. RESULTS From 2006 until 2014, 22 patients with a mean age of 57.2 years and mean BMI of 29,3 kg/m2 were studied. Sinuses were present in 21 patients. A recurrent ventral hernia was observed in 14 patients; two patients required a complex abdominal wall reconstruction due to enteric fistulas. Bowel resections or other potentially contaminated procedures were associated in 10 patients. Fourteen patients (63.6%) had an uneventful postoperative course; 5 (22.7%) patients had wound infections requiring debridement and three required partial (2) or total (1) mesh removal. Two patients died due to medical complications. Adverse results on long-term follow-up included one hernia recurrence after complete mesh removal and one persistent sinus after partial mesh removal requiring a reoperation to remove mesh remnants. All of the patients were considered free of infection after a mean follow-up of 44 months. CONCLUSIONS Synthetic mesh replacement in patients with active Staphylococcus aureus infection has an acceptable incidence of postoperative wound infection and prevents hernia recurrence. Large-pore polypropylene mesh is a suitable material to be used in the infected surgical field as an onlay graft.

Abstract
Introduction The incidence of deep infection using a synthetic mesh in inguinal hernia repair is low and reported to be well below 1%. This is in contrast to incisional hernia surgery where the reported incidence is 3% respective 13% comparing laparoscopic to open mesh repair reported in a Cochrane review. Main risk factors were long operation time, surgical site contamination, and early wound complications. An infected mesh can be preserved using conservative treatment were negative pressure wound therapy (VAC®) could play an important role. If strategy fails, the mesh needs to be removed. This review aims to look at evidence for situations were a biological mesh would work as a replacement of a removed infected synthetic mesh. Materials and methods A literature search of the Medline database was performed using the PubMed search engine. Twenty publications were found relevant for this review. Results For studies reviewed three options are presented: removal of the infected synthetic mesh alone, replacement with either a new synthetic or a new biological mesh. Operations were all performed at specialist centers. Removal of the mesh alone was an option limited to inguinal hernias. In ventral/incisional hernias, the use of a biological mesh for replacement resulted in a very high recurrence rate, if bridging was required. Either a synthetic or a biological mesh seems to work as a replacement when fascial closure can be achieved. Evidence is though very low. Conclusion When required, either a synthetic or a biological mesh seems to work as a replacement for an infected synthetic mesh if the defect can be closed. It is, however, not recommended to use a biological mesh for bridging. Mesh replacement surgery is demanding and is recommended to be performed in a specialist center.

Abstract
BACKGROUND Despite improved operative techniques, open ventral hernia repair (VHR) surgery in high-risk, potentially contaminated patients remains challenging. As previously reported by our group, the use of a modified negative-pressure wound therapy system (hybrid-VAC or HVAC) in patients with grade 2 hernias is associated with lower surgical site occurrence (SSO) and surgical site infection (SSI) rates. Accordingly, the authors aim to evaluate whether the HVAC would similarly improve surgical site outcomes following VHR in patients with grade 3 hernias. METHODS A 4-year retrospective review (2011-2014) was conducted of all consecutive, modified ventral hernia working group (VHWG) grade 3 hernia repairs with HVAC closure performed by a single surgeon (FEE) at a single institution. Operative data and 90-day outcomes were evaluated. Overall outcomes (e.g., recurrence, reoperation, mortality) were reviewed for the study group. RESULTS A total of 117 patients with an average age of 56.7 ± 11.9 years were classified as grade 3 hernias and underwent open VHR with subsequent HVAC closure. Fifty patients were male (42.7 %), the mean BMI was 35.2 (±9.5), and 60.7 % had a history of prior hernia repair. The average fascial defect size was 201.5 (±167.3) cm(2) and the mean length of stay was 14.2 (±9.3) days. Ninety-day outcomes showed an SSO rate of 20.7 % and an SSI rate of 5.2 %. The overall hernia recurrence rate was 4.2 % (n=6) with a mean follow-up of 11 ± 7.3 months. CONCLUSION Modified VHWG grade 3 ventral hernias are associated with significant morbidity. In our series utilizing the HVAC system after VHR, the observed rate of SSO and SSI compared favorably to reported series. Further prospective cost-effective studies are warranted to validate these findings.

Abstract
Grading systems developed by the Ventral Hernia Working Group (VHWG) for complex open abdominal wall reconstruction rely on limited outcomes: surgical site occurrence (SSO) and hernia recurrence. This does not account for the longitudinal restoration of a functional abdominal wall and the ability to correct complications. We performed a single-site, retrospective review of consecutive complex open abdominal wall reconstruction interventions with 24-month minimum follow-up to establish reoperation rates and compare long-term results to the VHWG. About 125 midline hernia repairs (>200 cm2) were studied. All had loss of functional domain and 47-month average follow-up. Demographics included: mean age 57 years, 47 per cent male, 63 per cent obese, and 34 per cent with contamination. Rates of SSO per VHWG grade were 9 per cent grade I, 45 per cent grade II, and 55 per cent grade III. Forty-three of 59 patients who developed complications were eventually successful after reoperation leading to an 87 per cent restoration rate. Select factors independently associated with reoperation included biological mesh and clinical history of infection. Although rates of SSO were higher than the VHWG published, we experienced high salvage rates except in patients who underwent biologic repair. We recommend restricted use of biologic mesh in contaminated and clean fields as well as modifications to the VHWG grading and recommendations.

Abstract
Actually the most common indications for Open Abdomen (OA) are trauma, abdominal sepsis, severe acute pancreatitis and more in general all those situations in which an intra-abdominal hypertension condition is present, in order to prevent the development of an abdominal compartment syndrome. The mortality and morbidity rate in patients undergone to OA procedures is still high. At present many studies have been published about the OA management and the progresses in survival rate of critically ill trauma and septic surgical patients. However several issues are still unclear and need more extensive studies. The definitions of indications, applications and methods to close the OA are still matter of debate. To overcome this lack of high level of evidence data about the OA indications, management, definitive closure and follow-up, the World Society of Emergency Surgery (WSES) promoted the International Register of Open Abdomen (IROA). The register will be held on a web platform (Clinical Registers®) through a dedicated web site: www.clinicalregisters.org. This will allow to all surgeons and physicians to participate from all around the world only by having a computer and a web connection. The IROA protocol has been approved by the coordinating center Ethical Committee (Papa Giovanni XXIII hospital, Bergamo, Italy). IROA has also been registered to ClinicalTrials.gov (ClinicalTrials.gov Identifier: NCT02382770).

Abstract
The indications for Open Abdomen (OA) are generally all those situations in which is ongoing the development an intra-abdominal hypertension condition (IAH), in order to prevent the development of abdominal compartmental syndrome (ACS). In fact all those involved in care of a critically ill patient should in the first instance think how to prevent IAH and ACS. In case of ACS goal directed therapy to achieve early opening and early closure is the key: paradigm of closure shifts to combination of therapies including negative pressure wound therapy and dynamic closure, in order to reduce complications and avoid incisional hernia. There have been huge studies and progress in survival of critically ill trauma and septic surgical patients: this in part has been through the great work of pioneers, scientific societies and their guidelines; however future studies and continued innovation are needed to better understand optimal treatment strategies and to define more clearly the indications, because OA by itself is still a morbid procedure.

Abstract
BACKGROUND The aim of this study is to evaluate the impact of concurrent mesh herniorrhaphy on short-term outcomes of colorectal surgery by using a large, nationwide database. METHODS Patients who underwent simultaneous ventral hernia repair (VHR) and colorectal surgery between 2005 and 2010 were identified from the American College of Surgeons National Surgical Quality Improvement Program. Patients who underwent VHR with mesh repair were case matched with patients who underwent VHR without mesh based on the type of colorectal procedure, diagnosis, and American Society of Anesthesiologists score. RESULTS Two hundred sixty-two patients who underwent VHR with mesh were case matched with 524 patients who underwent VHR without mesh. Mean operating time was significantly longer in patients who underwent VHR with mesh (195.8 ± 98.7 vs 164.3 ± 84.4 minutes, P < .001). Postoperative morbidity (P = .58), mortality (P = .27), superficial surgical site infection (SSI) (P = .14), deep SSI (P = .38), organ space SSI (P = .17), wound disruption (P > .99), reoperation (P = .48), and length of hospital stay (P = .71) were comparable between the groups. CONCLUSION The American College of Surgeons National Surgical Quality Improvement Program data suggest that VHR with mesh does not increase 30-day mortality, medical or surgical morbidity in colorectal surgery setting.

Abstract
Preserving patients' native tissues has posed many challenges for surgeons. Increased life expectancy is leading to a proportionately older surgical population with weaker tissues. The growing population of morbidly obese patients in addition to those with multiple comorbidities which influence the native strength and perfusion of tissues compounds the surgeon's challenge. Certainly, there is a rising demand for materials to replace or augment a patient's native tissue when it has been compromised. Over time, the number of products available has increased substantially. The ideal substitute, however, is debatable. The manufacturing and processing of these materials has become more complex and this has resulted in a significant increase in cost. The composition of the mesh, clinical scenario, and operative technique all interact to impact the long-term results. Surgeons require a thorough understanding of these products to guide proper selection and use, to ensure optimal outcomes for patients, and to properly steward financial resources. This review will outline the properties of commonly used materials, highlighting the strength and weakness of each. It will then discuss recommendations regarding mesh selection, coding, and reimbursement. While general principles and trends can be highlighted, further studies of biologic versus synthetic meshes are clearly necessary.

Abstract
BACKGROUND The use of biological materials for the repair of complex abdominal wall defects has increased over the years; however, the role of these materials in routine practice remains unclear. The aim of the study was to evaluate clinical outcomes following the use of Permacol™ porcine collagen surgical implant in complex abdominal wall repair. METHODS This subset analysis of seven European sites from a multicentre retrospective study included patients undergoing open or laparoscopic surgery and treated with Permacol™ surgical implant. Inguinal, parastomal, diaphragmatic, perineal, and hiatal repairs were excluded. Only patients with at least 12 months of follow-up after surgery were included. RESULTS A total of 109 patients (56 males and 53 females) were included. Patients had a median of two comorbidities (range 0-6). Thirty-three per cent of patients were treated for recurrent hernia. All but one case used an open approach. Sixty-six per cent were Center for Disease Control wound class II-IV at the time of surgery. Fascial closure was achieved in 69%. Median follow-up length was 720 days (range 368-2857). Recurrence rates at 1 and 2 years were 9.2 and 18.3 %, respectively, and were higher in cases without fascial closure. One-year recurrence was higher following use of an onlay technique (P = 0.025). In a multivariate analysis, among 16 comorbidities examined only fascial closure significantly impacted 1-year recurrence (P = 0.049). CONCLUSIONS Data from this large retrospective multicentre European study strongly suggest the use of Permacol™ porcine collagen surgical implant to be safe and effective for complex abdominal wall repair. The recurrence rate was impacted by fascial closure.

Abstract
INTRODUCTION Repair of contaminated abdominal wall defect in a geriatric patient is a challenge for the surgeon. We present the case of the oldest patient (105-years old) to successfully undergo a single-stage repair of a contaminated abdominal wall defect with a Permacol™ implant. CASE PRESENTATION A 105-year-old Caucasian woman presented to our emergency room with a clinical and radiological diagnosis of small bowel obstruction due to prior operative adhesions. She underwent laparotomy with small bowel resection and primary closure of her abdomen. There was total eventration of her bowel through the suture line 9 days after surgery. She underwent a second laparotomy that revealed no signs of peritonitis or turbid fluid. Her abdomen was closed with a 15 × 10 cm Permacol™ implant sutured sublay with prolene sutures. Her postoperative period was unremarkable. After a follow-up period of 3 years and 2 months, there was no sign of recurrent hernia or wound contamination. CONCLUSION We suggest that Permacol™ mesh can be considered an efficient alternative to primary closure or synthetic mesh in geriatric patients with contaminated abdominal wall defects.

Abstract
OBJECTIVE To evaluate the safety and long-term durability of 1-stage repair of enteric fistulas in the presence of an abdominal wall defect. BACKGROUND Patients with enteric fistulas and an abdominal wall defect present an extreme challenge to surgeons and have been associated with significant morbidity and mortality. Durability of repair is unknown as studies fail to report this or use limited follow-up periods. METHODS Chart review was done of consecutive patients who underwent 1-stage repair. Short-term outcomes included morbidity (wound and medical) and mortality. Long-term durability of repair was determined by prospective outpatient follow-up at least 3 years after surgery. RESULTS Thirty-nine patients were included with a mean age of 61.2 years, a mean BMI of 24.4 kg/m2, and a mean abdominal wall defect size of 247.9 cm2. Component separation technique was used in 34 (87.2%) and synthetic mesh in 13 (33.3%) patients. There was 1 (2.6%) postoperative death. Twenty-four wound complications developed in 18 (46.2%) patients, including surgical-site infection in 8 (20.5%) patients. Two (5.1%) enteric fistulas recurred and were treated conservatively resulting in closure. Medical complications were seen 36 times in 23 (59%) patients. Twelve of 33 (36.4%) living patients developed a recurrent hernia after a mean follow-up of 62.7 months (range: 36-130). CONCLUSIONS One-stage abdominal wall reconstruction with enteric fistula takedown is feasible at the cost of considerable morbidity. Our treatment strategy including component separation technique with synthetic mesh on-demand results in a durable repair in 6 to 7 of 10 patients.

Abstract
Skeletal muscle tissue has an inherent capacity for regeneration following injury. However, severe trauma, such as volumetric muscle loss, overwhelms these natural muscle repair mechanisms prompting the search for a tissue engineering/regenerative medicine approach to promote functional skeletal muscle restoration. A desirable approach involves a bioscaffold that simultaneously acts as an inductive microenvironment and as a cell/drug delivery vehicle to encourage muscle ingrowth. Both biologically active, naturally derived materials (such as extracellular matrix) and carefully engineered synthetic polymers have been developed to provide such a muscle regenerative environment. Next generation naturally derived/synthetic "hybrid materials" would combine the advantageous properties of these materials to create an optimal platform for cell/drug delivery and possess inherent bioactive properties. Advances in scaffolds using muscle tissue engineering are reviewed herein.

Abstract
Patients with incisional hernias (IH) and risk factors for surgical site occurrences (SSOs) such as defined comorbidities and/or potential contaminations are considered to be treated with bioprosthetics. A retrospective analysis of consecutive patients who had undergone elective IH repair with synthetic mesh materials between 2009 and 2013 was conducted. Only patients who were classified into Grades II and III according to the classification of the Ventral Hernia Working Group (VHWG) were considered for the study. Primary outcome parameter was the incidence of SSO. The relationships among demographics, hernia characteristics, surgical technique, and SSOs were also evaluated. Overall, 108 patients were included (Grade II: 68, Grade III: 40). SSO was identified in 14 patients. Having two or more comorbidities ( P = 0.04), an open sublay technique ( P = 0.005), duration of operation ( P = 0.02), larger hernia defects ( P = 0.001), and using larger mesh sizes ( P = 0.01) were associated with significantly higher rates of SSO. Affiliation to VHWG Grading II or III showed no impact on SSO occurrence. Synthetic mesh repair both in an “open sublay” and laparoscopic intraperitoneal technique is safe regarding patients with risk factors for SSO. The recommendations of the VHWG must be declined and a modification of the grading system is warranted overlooking a more liberal use of synthetic meshes.

Abstract
OBJECTIVE The study purpose was to evaluate the associations between patient characteristics or surgical site classifications and the histologic remodeling scores of biologic meshes biopsied from abdominal soft tissue repair sites in the first attempt to generate a multivariable risk-prediction model of nonconstructive remodeling. BACKGROUND Host characteristics and surgical site assessments may predict remodeling degree for biologic meshes used to reinforce abdominal tissue repair sites. METHODS Biologic meshes were biopsied from the abdominal tissue repair sites of n = 40 patients during an abdominal reexploration, stained with hematoxylin and eosin, and evaluated according to a semi-quantitative scoring system for remodeling characteristics (cell types, cell infiltration, extracellular matrix deposition, scaffold degradation, fibrous encapsulation, and neovascularization) and a mean composite score. Biopsies were stained with Sirius Red and Fast Green and analyzed to determine the collagen I:III ratio. On the basis of univariate analyses between subject clinical characteristics or surgical site classification and the histologic remodeling scores, cohort variables were selected for multivariable regression models using P ≤ 0.200. RESULTS The model selection process for cell infiltration score yielded 2 variables: age at mesh implantation and mesh classification (C statistic = 0.989). For the mean composite score, the model selection process yielded 2 variables: age at mesh implantation and mesh classification (r = 0.449). CONCLUSIONS These preliminary results constitute the first steps in generating a risk-prediction model that predicts the patients and clinical circumstances most likely to experience nonconstructive remodeling of abdominal tissue repair sites with biologic mesh reinforcement.

Abstract
The use of biologic mesh has increased greatly in recent years in response to the need for a solution in managing contaminated hernias. Multiple different meshes are commercially available, and are derived from a variety of sources, including human dermis as well as animal sources. For a mesh to be effective, it must be resistant to infection, have adequate tensile strength for hernia repair, and be well tolerated by the host. To achieve this end, biologic meshes go through an intense processing that varies from one product to the next. In this article, the authors review the types of mesh available, how they are processed, and examine these characteristics in terms of their strengths and weaknesses in application to surgical technique.

Abstract
Traumatic abdominal wall hernias (TAWHs) and traumatic abdominal aortic injuries (TAAIs) are complications of severe blunt trauma. CT is a sensitive imaging modality to detect TAWHs. As only severe TAAI will have positive physical exam findings, imaging techniques, surgical exploration, or on-table angiogram may aid in diagnosis.
INTRODUCTION Traumatic abdominal wall hernia (TAWH) and traumatic abdominal aortic injury (TAAI) are two uncommon complications secondary to blunt trauma. In both TAWH and TAAI, reported cases are often associated with poly-trauma. TAWH may be initially missed if more pressing issues are identified during the patient's primary survey. TAAI may be an incidental finding on imaging or, if severe, a cause of an acute abdomen and hemodynamic abnormality. PRESENTATION OF CASE A 54-year-old white male suffered a TAWH and TAAI (pseudoaneurysm) due to severe blunt trauma. TAWH was apparent on physical exam and the TAAI was suspected on computed tomography (CT). The patient's TAWH was managed with a series of abdominal explorations and the TAAI was repaired with endovascular stenting. DISCUSSION TAWH and TAAI are commonly due to severe blunt trauma from motor vehicle collisions. Diagnosis is made through physical exam, imaging studies, or surgical exploration. A variety of surgical techniques achieve technical success. CONCLUSION The patient with blunt trauma to the abdomen is at risk for TAWH and TAAI, which are often associated with other injuries. Investigations should include thorough clinical exam through secondary survey and radiologic imaging in the hemodynamically normal patient.

Abstract
PURPOSE Repair of hernia typically makes use of a prosthetic material; synthetic or biologic in nature. Any material which enters the body is subject to interrogation by the inflammation and immune system in addition to numerous other cell families, the outcome of which ultimately determines the success of the repair. In this review, we discuss the fundamental biology which occurs in situ when a biomaterial associates with a tissue, compare and contrast the techniques available to predict this in vitro, and review how features of hernia repair materials specifically may manipulate tissue interrogation and integration. Finally, we conclude our article by examining how biocompatibility impacts surgical practise and how a better understanding of the manner by which materials and tissues interact could benefit hernia repair. MATERIALS AND METHODS A review of the literature was conducted using appropriate scientific search engines in addition to inclusion of findings from the groups' primary research. RESULTS Using pre-clinical assays to anticipate the biocompatibility of a medical device is critical; however, to maximise the scientific power of in vitro findings, we must carefully consider the in vivo niche of the cells with which we are working. Excessive in vitro culture or contact to non-self materials can add compounding complexity to studies involving leucocytes for instance; therefore, we must ensure careful and stringent assay design when developing techniques for assaying pre-clinical biocompatibility. Furthermore, many of the features associated with hernia repair material design specifically, included to enhance their mechanical or biodegradation characteristics, are inadvertently instructive to cells, and therefore, throughout the prototype stages of a materials development, regular biocompatibility assessment must be performed. CONCLUSION The biocompatibility of a material is rate limiting in its ability to function as a medical device. The future of hernia repair materials will rely on close cohesion between the surgical and scientific communities to ensure the most robust biocompatibility assessment techniques, and models are utilised to predict the efficacy of a given material in a particular surgical application.

Abstract
INTRODUCTION Biologic grafts have been shown to support tissue regeneration in various animal models. Very few reports in the literature exist to show tissue remodeling in patients after placement of a biologic graft. CASE PRESENTATION We report the case of a 69-year-old Caucasian man with a history of small bowel carcinoid resection and concurrent recurrent ventral hernia repair with component separation and underlay biologic graft placement who underwent re-operation for metastatic carcinoid tumor to his liver. Complete incorporation of the biologic graft was observed. Tissue analysis of the incised midline fascia revealed tissue remodeling at the site of the previous abdominal wall defect. CONCLUSION Placement of a biologic graft in ventral hernia repair supports tissue regeneration similar to that previously reported in animal models.

Abstract
BACKGROUND Patient-reported outcomes are an important metric of the effectiveness of care. Ventral hernia repair is a procedure where the effectiveness can best be quantified using health-related quality of life. This study sought to quantify quality of life with respect to costs of ventral hernia repair. METHODS This observational study of patients diagnosed with a ventral hernia between 2004-2011 in a single center identified 3 groups of patients: (1) Patients diagnosed with ventral hernias managed with observation, (2) patients diagnosed with ventral hernias who underwent operative repair only when incarceration occurred, and (3) patients with ventral hernias who underwent herniorraphy before incarceration. The Short Form (SF)12v2 was administered to measure quality of life. The direct costs of care were obtained from Financial Services. Patients were surveyed about direct, non-health costs to obtain a societal perspective. A cost-utility analysis was performed. RESULTS The SF-12v2 was administered to 243 patients; 80 were observed, 69 underwent repair of an incarcerated hernia, and 94 underwent repair of a nonincarcerated hernia. The response rates were similar among groups-59%, 55%, and 52%. Quality of life as measured by utility score was less at 0.68 (95% CI, 0.65-0.71) in patients who did not undergo repair compared with those after repair of a nonincarcerated hernia, 0.76 (95% CI, 0.73-0.79; P < .001). The elective repair of a nonincarcerated hernia was cost-effective with an incremental cost effectiveness ratio of $8,646 per quality-adjusted life-year. CONCLUSION The prompt elective repair of ventral hernias is cost-effective.

Abstract
Traumatic abdominal wall hernia after blunt trauma is a rare entity. They can easily be overlooked in patients who have multiple trauma, as its signs and symptoms may be variable due to the presence of multiple injuries. Imaging with computed tomography or ultrasound confirms the diagnosis as well as identifying any associated injuries. Although surgery is the standard treatment for traumatic abdominal wall hernias, there is no consensus on the early or late repair of the defect. Some authors recommend early surgical intervention in order to avoid the risk of intra-abdominal organ injury, incarceration, and strangulation. In this study, we report our experience in three cases, which did not involve emergency surgery. Long-term outcome is successful. Elective hernia repair may be safe and feasible in stable patients.

[PMID: 24933669 DOI: 10.1016/j.amjsurg.2014.02.013] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2013] [Revised: 02/04/2014] [Accepted: 02/24/2014] [Indexed: 11/18/2022]
Abstract
BACKGROUND Recurrence rates after component separation technique (CST) are low in the literature but may be underestimated because of inadequate follow-up methods. METHODS Prospective patient follow-up was performed of consecutive patients who underwent repair of large and complex ventral hernias using CST without mesh utilization. Primary outcome was recurrent hernia determined by clinical examination at least 1 year after surgery in all living patients. Current literature underwent meta-analysis regarding outcomes and mode of follow-up. RESULTS Seventy-five patients were included with a mean age of 52.2 years and a mean defect size of 214.9 cm(2), respectively. Twenty-nine patients (38.7%) had a recurrent hernia after a mean of 40.9-month follow-up, and this was significantly higher than in the literature (14.0%, P < .01). Sixty-four percent of studies in the literature were unclear about the method of determining recurrent hernia or included telephone follow-up and questionnaires. CONCLUSIONS CST coincides with a high recurrence rate when clinical follow-up is longer than a year. Reported recurrence rates are probably underestimated because the method and duration of follow-up are inadequate.

Abstract
Complex abdominal wall reconstruction (AWR) is commonly performed, but with a significant rate of surgical complications and hernia recurrence. The aim of this experiential review is to assess risk factors for hernia recurrence after complex AWR. A retrospective review of AWR patients from 2007-2012 was performed. Rates of hernia recurrence were assessed. Univariate analyses and subsequent multivariate logistic regression analysis was used to assess independent predictors of early hernia recurrence. One hundred and thirty-four consecutive cases of AWR were performed over a 5-year period. Hernia recurrence developed in 14 (10.4%) patients. Hernias derived from trauma (OR = 19.76, p = 0.011) and those who experienced postoperative wound infections (OR = 18.81, p = 0.004) were at increased risk for hernia recurrence. In conclusion, increased vigilance must be paid to patients presenting after trauma with massive loss of domain and those who experience postoperative infection, as these cohorts are at added risk for failed reconstruction.

Abstract
BACKGROUND Guidelines recommend the use of bioprosthetics for abdominal wall reinforcement in contaminated fields, but the evidence supporting the use of biologic over synthetic non-absorbable prosthetics for this indication is poor. Therefore, the objective was to perform a systematic review of outcomes after synthetic non-absorbable and biologic prosthetics for ventral hernia repair or prophylaxis in contaminated fields. METHODS The systematic literature search identified all articles published up to 2013 that reported outcomes after abdominal wall reinforcement using synthetic non-absorbable or biologic prosthetics in contaminated fields. Studies were included if they included at least 10 cases (excluding inguinal and parastomal hernias). Quality assessment was performed using the MINORS instrument. The main outcomes measures were the incidence of wound infection and hernia at follow-up. Weighted pooled proportions were calculated using a random effects model. RESULTS A total of 32 studies met the inclusion criteria and were included for synthesis. Mean sample size was 41.4 (range 10-190), and duration of follow-up was >1 year in 72 % of studies. Overall quality was low (mean 6.2, range 1-12). Pooled wound infection rates were 31.6 % (95 % CI 14.5-48.7) with biologic and 6.4 % (95 % CI 3.4-9.4) with synthetic non-absorbable prosthetics in clean-contaminated cases, with similar hernia rates. In contaminated and/or dirty fields, wound infection rates were similar, but pooled hernia rates were 27.2 % (95 % CI 9.5-44.9) with biologic and 3.2 % (95 % CI 0.0-11.0) with synthetic non-absorbable. Other outcomes were comparable. CONCLUSIONS The available evidence is limited, but does not support the superiority of biologic over synthetic non-absorbable prosthetics in contaminated fields.

Abstract
The presence of a contaminated surgical field in abdominal wall defects caused by trauma presents a challenge for surgeons. Both primary suture and synthetic meshes are strongly discouraged as surgical treatments in such cases. We describe the use of a porcine dermal collagen (Permacol) implant in an eight-year-old patient with multiple injuries. Three months after discharge, the child remains well with good cosmetic results. He is free of pain and has returned to full activity levels with complete wound closure and without any evidence of residual hernia. In conclusion, our experience indicates that the use of Permacol can be considered an efficient technique for reconstructing an infected abdominal wall defect of a pediatric multitrauma patient.

Abstract
Soft-tissue reconstruction for a variety of surgical conditions, such as abdominal wall hernia or pelvic organ prolapse, remains a challenge. There are numerous meshes available that may be simply categorized as either synthetic or biologic. Within biologic meshes, porcine dermal meshes have come to dominate the market. This review examines the current evidence for their use and the limitations of knowledge. Although there is increasing evidence to support their safety, long-term follow-up studies that support their efficacy are lacking. Numerous clinical trials that remain ongoing may help elucidate their precise role in soft-tissue reconstruction.

A retrospective review and observations over a 16-year clinical experience on the surgical treatment of chronic mesh infection. What about replacing a synthetic mesh on the infected surgical field? Hernia 2014; 19:239-46. [PMID: 24509890 DOI: 10.1007/s10029-014-1225-9] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2013] [Accepted: 01/26/2014] [Indexed: 10/25/2022]
Abstract
PURPOSE To review the short- and long-term results in patients who underwent removal of infected or exposed mesh and reconstruction of the abdominal wall with simultaneous mesh replacement. METHODS Patients undergoing removal of an infected or exposed mesh and single-staged reconstruction of the abdominal wall with synthetic mesh replacement over a 16-year period were retrospectively reviewed from a prospectively maintained database. Patients were operated and followed by a single surgeon. Outcome measures included wound complications and hernia recurrence. RESULTS From 1996 until 2012, 41 patients (23 F, 18 M), with a mean age of 53.4 years and mean BMI of 31.2 ± 8 kg/m(2), were treated for chronic mesh infection (CMI). A suppurative infection was present in 27 patients, and 14 had an exposed mesh. The need for recurrent incisional hernia repair was observed in 25 patients; bowel resections or other potentially contaminated procedures were associated in 15 patients. The short-term results showed an uneventful post-operative course after mesh replacement in 27 patients; 6 (14.6%) patients developed a minor wound infection and were treated with dressings and antibiotics; 5 (12%) patients had wound infections requiring debridement and one required complete mesh removal. On the long-term follow-up, there were three hernia recurrences, one of which demanded a reoperation for enterocutaneous fistula; 95% of the patients submitted to mesh replacement were considered cured of CMI after a mean follow-up of 74 months. CONCLUSIONS CMI can be treated by removal of infected mesh; simultaneous mesh replacement prevents hernia recurrence and has an acceptable incidence of post-operative acute infection. Standard polypropylene mesh is a suitable material to be used in the infected surgical field as an onlay graft.
