Abstract
PURPOSE Ventral hernias are a common complication of laparotomy, posing challenges particularly when primary fascial closure is unattainable. Although chemical component separation using preoperative botulinum toxin A (BTX) injections has emerged as a promising adjunct, objective evidence of its efficacy remains limited. This study aimed to objectively assess the effect of preoperative BTX on traction force during ventral hernia repair. METHODS A prospective, single-blind study was conducted on patients with midline incisional hernias following liver transplantation. BTX was administered unilaterally, and the traction force required to medially advance the anterior rectus sheath was measured intraoperatively. Pre- and post-injection CT scans were analyzed for changes in hernia size and LAW muscle measurements. Statistical analyses were performed to evaluate traction force differences between BTX-injected and uninjected sides. RESULTS Ten patients underwent hernia repair with primary fascial closure achieved in all cases. Comparison of pre- and post-injection CT scans showed no significant changes in hernia size. LAW muscle length increased by 1.8 cm, while thickness decreased by 0.2 cm. Intraoperative traction force measurements revealed a significant reduction on the BTX-injected side compared to the uninjected side (p < 0.0001). The traction force ratio on the BTX-injected to the uninjected side averaged 57%, indicating the efficacy of BTX in reducing tension. CONCLUSION Preoperative BTX significantly reduces traction force during ventral hernia repair, highlighting its potential as an adjunctive therapy in complex cases. While challenges remain in patient selection and outcome assessment, BTX offers a promising avenue for enhancing abdominal wall reconstruction outcomes and reducing surgical complications.

Three-year outcome after anterior component separation repair of giant ventral hernias: A retrospective analysis of the original technique without mesh. Asian J Surg 2021; 45:1117-1121.

Abstract
INTRODUCTION In this study we presented our results with anterior component separation technique utilized in the repair of giant ventral hernias. Our primary endpoints were the rates of surgical site occurrences and recurrence at three years. Besides we investigated the impact of components separation repair on abdominal wall functions. METHODS We retrospectively analyzed the prospectively-collected data of 40 patients that were operated on between April 2004 and February 2012 for their median ventral hernias sizing larger than 15 cm in width. Our inclusion criteria for component separation program excellently corresponded today's "giant ventral hernia" standards. The method used for components separation was identical to the original Ramirez technique, and did not comprise of any mesh reinforcement. The ICU stays, prolonged intubation, early and late complications, mortality and recurrences at three years were recorded. We used a curl-up test to demonstrate the amelioration of the abdominal wall functions postoperatively. RESULTS The older age and larger defect size were the significant risk factors necessitating prolonged intensive care. Surgical site occurrences were recorded in 18 patients (45.0%). A total of 7 recurrences (17.5%) were detected at three years. Patients showed a significant improvement in raising their trunks after repair (p < 0.001). CONCLUSIONS Our findings demonstrated that components separation technique in the original form caused excessive wound complications including skin necrosis which in turn caused delayed discharge from the hospital. The 17.5% recurrence rate seemed higher than those of more recent papers. The already-established newer modifications should be integrated in the repair method. The components separation repair clearly improves abdominal wall functions.

Abstract
Background The surgical treatment of patients with complex ventral hernias is challenging. The aim of this study was to present an international overview of expert opinions on current practice. Methods A survey questionnaire was designed to investigate preoperative risk management, surgical approach and mesh choice in patients undergoing complex hernias repair, and treatment strategies for infected meshes. Geographical location of practice, experience and annual volumes of the surgeons were compared. Results Of 408 surgeons, 234 (57.4 per cent) were practising in the USA, 116 (28.4 per cent) in Europe, and 58 (14.2 per cent) in other countries. Some 412 of 418 surgeons (98.6 per cent) performed open repair and 322 of 416 (77.4 per cent) performed laparoscopic repair. Most recommended preoperative work-up/lifestyle changes such as smoking cessation (319 of 398, 80.2 per cent) and weight loss (254 of 399, 63.7 per cent), but the consequences of these strategies varied. American surgeons and less experienced surgeons were stricter. Antibiotics were given at least 1 h before surgery by 295 of 414 respondents (71.3 per cent). Synthetic and biological meshes were used equally in contaminated primary hernia repair, whereas for recurrent hernia repair synthetic mesh was used in a clean environment and biological or no mesh in a contaminated environment. American surgeons and surgeons with less experience preferred biological mesh in contaminated environments significantly more often. Percutaneous drainage and antibiotics were the first steps recommended in treating mesh infection. In the presence of sepsis, most surgeons favoured synthetic mesh explantation and further repair with biological mesh. Conclusion There remains a paucity of good-quality evidence in dealing with these hernias, leading to variations in management. Patient optimization and issues related to mesh choice and infections require well designed prospective studies.

Abstract
PURPOSE The use of mesh in ventral hernia repair becomes especially challenging when associated with a contaminated field. Permanent synthetic mesh use in this setting is currently debated and this discussion is yet to be resolved clinically or in the literature. We aim to systematically assess postoperative outcomes of non-absorbable synthetic mesh (NASM) used in ventral hernia repair in the setting of contamination. METHODS A literature search of PubMed, Embase, Scopus, Cinahl, and Cochrane Library identified all articles from 2000-2020 that examined the use of NASM for ventral hernia repair in a contaminated field. Postoperative outcomes were assessed by means of pooled analysis and meta-analysis. Qualitative analysis was completed for all included studies using a modified Newcastle-Ottawa scale. RESULTS Of 630 distinct publications and 104 requiring full review, this study included 17 articles published between 2007 and 2020. Meta-analysis demonstrated absorbable mesh was associated with more HR (OR 1.89, 1.15-3.12, p = 0.008), SSO (OR 1.43, 0.96-2.11, p = 0.087), SSI (OR 2.84, 1.85-4.35, p < 0.001), and unplanned reoperation (OR 1.99, 1.19-3.32, p = 0.009) compared to NASM. CONCLUSION The use of NASM for ventral hernia repair in a contaminated field may be a safe alternative to absorbable mesh, as evidenced by lower rates of postoperative complications. This review counters the current clinical paradigm, and additional prospective randomized controlled trials are warranted.

Outcomes of a new slowly resorbable biosynthetic mesh (Phasix™) in potentially contaminated incisional hernias: A prospective, multi-center, single-arm trial. Int J Surg 2020; 83:31-36.

Abstract
BACKGROUND Resorbable biomaterials have been developed to reduce the amount of foreign material remaining in the body after hernia repair over the long-term. However, on the short-term, these resorbable materials should render acceptable results with regard to complications, infections, and reoperations to be considered for repair. Additionally, the rate of resorption should not be any faster than collagen deposition and maturation; leading to early hernia recurrence. Therefore, the objective of this study was to collect data on the short-term performance of a new resorbable biosynthetic mesh (Phasix™) in patients requiring Ventral Hernia Working Group (VHWG) Grade 3 midline incisional hernia repair. MATERIALS AND METHODS A prospective, multi-center, single-arm trial was conducted at surgical departments in 15 hospitals across Europe. Patients aged ≥18, scheduled to undergo elective Ventral Hernia Working Group Grade 3 hernia repair of a hernia larger than 10 cm2 were included. Hernia repair was performed with Phasix™ Mesh in sublay position when achievable. The primary outcome was the rate of surgical site occurrence (SSO), including infections, that required intervention until 3 months after repair. RESULTS In total, 84 patients were treated with Phasix™ Mesh. Twenty-two patients (26.2%) developed 32 surgical site occurrences. These included 11 surgical site infections, 9 wound dehiscences, 7 seromas, 2 hematomas, 2 skin necroses, and 1 fistula. No significant differences in surgical site occurrence development were found between groups repaired with or without component separation technique, and between clean-contaminated or contaminated wound sites. At three months, there were no hernia recurrences. CONCLUSION Phasix™ Mesh demonstrated acceptable postoperative surgical site occurrence rates in patients with a Ventral Hernia Working Group Grade 3 hernia. Longer follow-up is needed to evaluate the recurrence rate and the effects on quality of life. This study is ongoing through 24 months of follow-up.

Abstract
BACKGROUND Ventral hernias are common after Hartmann's procedure and add complexity to Hartmann's reversal. Colostomy reversal and abdominal wall reconstruction may be performed in a staged or concurrent fashion, although data are limited as to which strategy is optimal. We aimed to define the complication profile of concurrent abdominal wall reconstruction with colostomy reversal as compared to either procedure alone. MATERIALS AND METHODS For this retrospective cohort study, we used the National Surgery Quality Improvement Project Database from 2012 to 2015. All patients undergoing elective colostomy reversal, abdominal wall reconstruction with component separation, or combined colostomy reversal with component separation were identified. Propensity score matching was used to compare outcomes among similar patients undergoing colostomy reversal alone versus combined procedure. Groups were evaluated for postoperative morbidity including reoperation. RESULTS We identified 11,689 patients; 6951 (64%) underwent component separation alone, 4563 (35%) colostomy reversal alone, and 175 (1%) combined component separation and colostomy reversal. The combined group, as compared to colostomy reversal alone, showed an increased overall complication rate (39% versus 25%; P < 0.01) and increased rate of reoperation (9% versus 5%; P = 0.03). Differences in overall complication rate (43% versus 24%; P < 0.01) and reoperation rate (9% versus 3%; P = 0.03) persisted on propensity matched analysis. CONCLUSIONS This analysis shows that in patients undergoing colostomy takedown, concurrent abdominal wall reconstruction is associated with increased morbidity including increased rate of reoperation, even when controlling for patient factors. Consideration may be given to a staged approach.

Abstract
Background The component separation technique (CST) is considered an excellent technique for complex ventral hernia repair. However, postoperative infectious complications and reherniation rates are significant. Risk factor analysis for postoperative complication and reherniation has focused mostly on patient history and co-morbidity and shows equivocal results. The use of abdominal morphometrics derived from CT scans to assist in risk assessment seems promising. The aim of this study is to determine the predictability of reherniation and surgical site infections (SSI) using pre-operative CT measurements. Methods Electronic patient records were searched for patients who underwent CST between 2000 and 2013 and had a pre-operative CT scan available. Visceral fat volume (VFV), subcutaneous fat volume (SFV), loss of domain (LOD), rectus thickness and width (RT, RW), abdominal volume, hernia sac volume, total fat volume (TFV), sagittal distance (SD) and waist circumference (WC) were measured or calculated. Relevant variables were entered in multivariate regression analysis to determine their effect on reherniation and SSI as separate outcomes. Results Sixty-five patients were included. VFV (p = 0.025, OR = 1.65) was a significant predictor regarding reherniation. Hernia sac volume (p = 0.020, OR = 2.10) and SFV per 1000 cm3 (p = 0.034, OR = 0.26) were significant predictors of SSI. Conclusion Visceral fat volume, subcutaneous fat volume and hernia sac volume derived from CT scan measurements may be used to predict reherniation and SSI in patients undergoing complex ventral hernia repair using CST. These findings may aid in optimizing patient-tailored preoperative risk assessment.

Abstract
Surgeons' comfort with abdominal wall reconstruction techniques and use of prosthetic reinforcement in contaminated fields has made repair of complex hernias during concomitant procedures an attractive endeavor. Understanding the precarious nature of this practice, tenets of thoughtful patient selection, and principles of repair that mitigate morbidity can allow for an educated thought process when deciding whether or not to pursue concomitant abdominal wall reconstruction.

Abstract
BACKGROUND We sought to evaluate the results of a new mesh sutured repair technique for closure of contaminated incisional hernias. METHODS 48 patients with contaminated hernias 5 cm wide or greater by CT scan were closed with mesh sutures. Surgical site occurrence, infections, and hernia recurrence were compared to similar patient series reported in the literature. RESULTS Of the 48 patients, 20 had clean-contaminated wounds, 16 had contaminated wounds, and 12 were infected. 69% of the patients underwent an anterior perforator sparing components release for hernias that averaged 10.5 cm transversely (range 5 cm-25 cm). SSO occurred in 27% of patients while SSI was 19%. There were no fistulas or delayed suture sinuses. With a mean follow-up of almost 12 months, 3 midline hernias recurred (6%). In these same patients, three parastomal hernias repaired with mesh sutures failed out of 4 attempted for a total failure rate of 13%. CONCLUSION Mesh sutured closure represents a simplified and effective surgical strategy for contaminated midline incisional hernia repair.

Abstract
Background: The reported incidence of mesh infection in contaminated operative fields is as high as 30% regardless of material used. Our laboratory previously showed that augmenting acellular bioprosthetic mesh with allogeneic mesenchymal stem cells (MSC) enhances resistance to bacterial colonization in vivo and preserves mesh integrity. This study’s aim was to determine whether augmentation of non-crosslinked porcine dermis (Strattice) with commercially available, cryopreserved, viable MSC-containing human placental tissue (Stravix) similarly improves infection resistance after inoculation with Escherichia coli (E. coli) using an established mesh infection model. Methods: Stravix was thawed per manufacturer’s instructions and 2 samples were tested for cell viability using a Live/Dead Cell assay at the time of surgery. Rats (N = 20) were implanted subcutaneously with 1 piece of Strattice and 1 piece of hybrid mesh (Strattice + Stravix sutured at the corners). Rats were inoculated with either sterile saline or 106 colony-forming units of E. coli before wound closure (n = 10 per group). At 4 weeks, explants underwent microbiologic and histologic analyses. Results: In E. coli–inoculated animals, severe or complete mesh degradation concurrent with abscess formation was observed in 100% (10/10) hybrid meshes and 90% (9/10) Strattice meshes. Histologic evaluation determined that meshes inoculated with E. coli exhibited severe acute inflammation, which correlated with bacterial recovery (P < 0.001). Viability assays performed at the time of surgery failed to verify the presence of numerous live cells in Stravix. Conclusions: Stravix cryopreserved MSC-containing human umbilical tissue does not improve infection resistance of a bioprosthetic mesh in vivo in rats after inoculation with E. coli.

Abstract
BACKGROUND Ventral hernia represents a surgical challenge plagued by high morbidity and recurrence rates. Primary closure of challenging hernias is often prohibited by severe lateral retraction and tension of the abdominal wall musculature. Botulinum toxin injections have recently been identified as a potential pre-operative means to counteract abdominal wall tension, reduce hernia size, and facilitate fascial closure during hernia repair. This systematic review and meta-analysis reviews outcomes associated with botulinum toxin injections in the setting of ventral hernia, and demonstrates an opportunity to leverage this mainstream aesthetic product for use in abdominal wall reconstruction. METHODS A literature review was conducted according to PRISMA guidelines using MeSH terms 'ventral hernia', 'herniorrhaphy', 'hernia repair', and 'botulinum toxins'. Relevant studies reporting pre- and postinjection data were included. Outcomes of interest included changes in hernia defect width and lateral abdominal muscle length, recurrence, complications, and patient follow-up. Qualitative findings were also considered to help demonstrate valuable themes across the literature. RESULTS Of 133 results, 12 were included for qualitative review and three for quantitative analysis. Meta-analysis revealed significant hernia width reduction (mean = 5.79 cm; n = 29; p < 0.001) and lateral abdominal wall muscular lengthening (mean = 3.33 cm; n = 44; p < 0.001) following botulinum injections. Mean length of follow-up was 24.7 months (range = 9-49). CONCLUSIONS Botulinum toxin injections offer tremendous potential in ventral hernia management by reducing hernia width and lengthening abdominal wall muscles prior to repair. Although further studies are needed, there is a significant opportunity to bridge the knowledge gap in preoperative practice measures for ventral hernia risk reduction.

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.
