Project description:IntroductionVentral hernia repair is one of the most common surgeries performed in the United States. Failure of hernia repairs can be attributed to sutures pulling through tissue or mesh (anchor point failure). T-Line Hernia Mesh is the first mesh designed to specifically prevent anchor point failure by distributing tension. This case study of two patients is the first clinical application of the novel T-Line Hernia Mesh.Presentation of caseTwo separate patients presented with symptomatic ventral hernia secondary to previous laparotomy. Patient 1 is a fifty-five year-old male who underwent open ventral hernia repair with T-Line Hernia Mesh onlay placement. Patient 2 is a fifty-eight year-old female with a symptomatic ventral hernia that underwent bilateral component separation and primary hernia repair with T-Line Hernia Mesh. Both patients postoperative course was uneventful with no reported surgical site occurrences or hernia recurrence.DiscussionT-Line Hernia Mesh provides a new innovative approach to hernia surgery. This provides the first clinical outcomes. No complications were observed. In addition, this manuscript also demonstrates the surgical technique for the first time.ConclusionThis cases and technical description provides the initial report for a new designed T-Line Hernia Mesh that could result in a paradigm shift in hernia surgery concepts.

Project description:The introduction of mesh for reinforcement of ventral hernia repair (VHR) led to a significant reduction in hernia recurrence rates. However, it remains controversial whether synthetic or biologic mesh leads to superior outcomes. Recently, hybrid mesh consisting of reinforced biosynthetic ovine rumen (RBOR) has been developed and aims to combine the advantages of biologic and synthetic mesh; however, outcomes after VHR with RBOR have not yet been compared with the standard of care.MethodsWe performed a retrospective analysis on 109 patients, who underwent VHR with RBOR (n = 50) or synthetic polypropylene mesh (n = 59). Demographic characteristics, comorbidities, postoperative complications, and recurrence rates were analyzed and compared between the groups. Multivariate logistic regression models were fit to assess associations of mesh type with overall complications and surgical site occurrence (SSO).ResultsPatients who underwent VHR with RBOR were older (mean age 63.7 versus 58.8 years, P = 0.02) and had a higher rate of renal disease (28.0 versus 10.2%, P = 0.01) compared with patients with synthetic mesh. Despite an unfavorable risk profile, patients with RBOR had lower rates of SSO (16.0 versus 30.5%, P = 0.12) and similar hernia recurrence rates (4.0 versus 6.78%, P = 0.68) compared with patients with synthetic mesh. The use of synthetic mesh was significantly associated with higher odds for overall complications (3.78, P < 0.05) and SSO (3.87, P < 0.05).ConclusionCompared with synthetic polypropylene mesh, the use of RBOR for VHR mitigates SSO while maintaining low hernia recurrence rates at 30-month follow-up.

Project description:Purpose:Parastomal hernia is a common complication following a stoma and may cause leakage or incarceration. No optimal treatment has been established, and existing methods using mesh repair are associated with high recurrence rates and a considerable risk for short- and long-term complications including death. A double-layer intraperitoneal on-lay mesh (IPOM), the Parastomal Hernia Patch (BARD™), consisting of ePTFE and polypropylene, has been developed and tailored to avoid recurrence. To evaluate the safety of and recurrence rate using this mesh, a nonrandomised prospective multicentre study was performed. Method:Fifty patients requiring surgery for parastomal hernia were enrolled. Clinical examination and CT scan prior to surgery were performed. All patients were operated on using the Parastomal Hernia Patch (BARD). Postoperative follow-up at one month and one year was scheduled to detect complications and hernia recurrence. Results:The postoperative complication rate at one month was 15/50 (30%). The parastomal hernia recurrence rate at one year was 11/50 (22%). The reoperation rate at one month was 7/50 (14%), and further 5/50 (10%) patients were reoperated on during the following eleven months.

Project description:Objective: The aim of this study was to compare the likelihood of bowel obstruction according to the placement of the mesh (either intraperitoneal or extraperitoneal) in ventral hernia repairs. Materials and methods: Patients were divided into two groups, an intraperitoneal (IP) group (mesh placed by laparoscopy or with an open approach) and an extraperitoneal (EP) group, all operated on in the Digestive Surgery Department at the Dijon University Hospital. The primary outcome was the occurrence of an episode of bowel obstruction requiring hospitalization and confirmed by abdominal CT scan. Results: Between March 2008 and July 2021, 318 patients were included, with 99 patients in the EP group (71 meshes placed preperitoneally and 28 placed retromuscularly) and 219 patients in the IP group (175 patients operated on laparoscopically versus 44 patients by direct approach). Three patients presented an episode of acute intestinal obstruction, with no difference between the two groups (p = 0.245), although all bowel obstructions occurred in the IP group and with the laparoscopic approach (1.7% of patients operated on by laparoscopy). The occlusive events occurred at 1 month, 2 years, and 3 years. There was no difference in terms of recurrence or postoperative chronic pain. There were more seroma and mesh infections in the EP group (p < 0.05). Two patients operated on by laparoscopy had undetected bowel injuries, prompting emergent surgery for peritonitis. Conclusions: No statistically significant difference was found in terms of bowel obstruction between the intraperitoneal and the extraperitoneal position, but all cases of obstruction happened in the intraperitoneal mesh group. Visceral lesions remain a major complication of the laparoscopic approach that should not be neglected.

Project description:Within the past decade, poly-4-hydroxybutyrate (P4HB) biosynthetic mesh has been introduced as a potential alternative to traditional biologic and synthetic mesh in ventral hernia repair (VHR). The aim of this study was to systematically assess clinical outcomes with the P4HB in VHR.MethodsA literature search identified all articles published in 2000 involving the use of P4HB in VHR. Descriptive statistics were used to synthesize collective data points, including postoperative outcomes. A pooled analysis of postoperative outcomes was performed using chi-square test and Fisher exact test.ResultsAcross 7 studies, the P4HB was used in 453 patients. The mean rate of surgical site infection (SSI) was 6.8% (31/453), reoperation 10.7% (30/281), and recurrence 9.1% (41/453). At an average follow-up of 26.8 months, the incidence of recurrence was 10.4% (28/270). Onlay was significantly associated with increased recurrence (14.2% versus 4.4%, P = 0.001). Among sublay placements, there was no difference in recurrence in clean (Center for Disease Control [CDC] 1) or contaminated (CDC >1) wounds (2.7% versus 6.1%, P = 0.585), but contaminated wounds were associated with increased SSI (2.7% versus 15.2%, P = 0.028). Ventral Hernia Working Group grade 2 and 3 did not have different incidences of recurrence (8.0% versus 5.1%, P = 0.526) nor SSI (5.1% versus 14.6%, P = 0.265).ConclusionsOverall, clinical outcomes of the P4HB mesh in VHR are acceptable. The P4HB mesh serves as a reliable alternative to traditional synthetic and biologic mesh across a range of defect characteristics and patient health conditions. Further research is needed to better understand the conditions in which it may provide a clinical benefit over traditional mesh types.

Project description:PurposeThe use of mesh is a common practice in ventral hernia repair (VHR). Lack of consensus on which prosthetic material works better in different settings remains. This meta-analysis aims to summarize the available evidence on hernia recurrence and complications after repair with synthetic, biologic, or biosynthetic/bioabsorbable meshes in hernias grade 2-3 of the Ventral Hernia Working Group modified classification.MethodsA literature search was conducted in January 2021 using Web of Science (WoS), Scopus, and MEDLINE (via PubMed) databases. Randomized Controlled Trials (RCTs) and observational studies with adult patients undergoing VHR with either synthetic, biologic, or biosynthetic/bioabsorbable mesh were included. Outcomes were hernia recurrence, Surgical Site Occurrence (SSO), Surgical Site Infection (SSI), 30 days re-intervention, and infected mesh removal. Random-effects meta-analyses of pooled proportions were performed. Quality of the studies was assessed, and heterogeneity was explored through sensitivity analyses.Results25 articles were eligible for inclusion. Mean age ranged from 47 to 64 years and participants' follow-up ranged from 1 to 36 months. Biosynthetic/bioabsorbable mesh reported a 9% (95% CI 2-19%) rate of hernia recurrence, lower than synthetic and biologic meshes. Biosynthetic/bioabsorbable mesh repair also showed a lower incidence of SSI, with a 14% (95% CI 6-24%) rate, and there was no evidence of infected mesh removal. Rates of seroma were similar for the different materials.ConclusionsThis meta-analysis did not show meaningful differences among materials. However, the best proportions towards lower recurrence and complication rates after grade 2-3 VHR were after using biosynthetic/slowly absorbable mesh reinforcement. These results should be taken with caution, as head-to-head comparative studies between biosynthetic and synthetic/biologic meshes are lacking. Although, biosynthetic/bioabsorbable materials could be considered an alternative to synthetic and biologic mesh reinforcement in these settings.

Project description:BackgroundMany patients develop seroma after laparoscopic ventral hernia repair. It was hypothesized that leaving the hernial sac in situ may cause this complication.MethodsIn this patient- and outcome assessor-blinded, parallel-design single-centre trial, patients undergoing laparoscopic intraperitoneal onlay mesh ventral hernia repair were randomized (1 : 1) to either conventional fascial closure or peritoneal bridging. The primary endpoint was the incidence of seroma 12 months after index surgery detected by CT, evaluated in an intention-to-treat analysis.ResultsBetween September 2017 and May 2018, 62 patients were assessed for eligibility, of whom 25 were randomized to conventional closure and 25 to peritoneal bridging. At 3 months, one patient was lost to follow-up in the conventional and peritoneal bridging groups respectively. No seroma was detected at 6 or 12 months in either group. The prevalence of clinical seroma was four of 25 (16 (95 per cent c.i. 2 to 30) per cent) versus none of 25 patients in the conventional fascial closure and peritoneal bridging groups respectively at 1 month after surgery (P = 0·110), and two of 24 (8 (0 to 19) per cent) versus none of 25 at 3 months (P = 0·235). There were no significant differences between the groups in other postoperative complications (one of 25 versus 0 of 25), rate of recurrent hernia within 1 year (none in either group) or postoperative pain.ConclusionConventional fascial closure and peritoneal bridging did not differ with regard to seroma formation after laparoscopic ventral hernia repair.Trial registrationClinicalTrials.gov (NCT03344575).

Project description:BACKGROUND:Current data on shrinkage of intraperitoneal meshes come mainly from animal studies. High-quality human data in prospective studies are scarce. METHODS:We used the ability to visualize intraperitoneal PVDF meshes enhanced with iron particles (DynaMesh IPOM visible) with magnetic resonance imaging (MRI) to determine the amount of shrinkage between 1 and 13 months postoperatively. All measurements of the width, length, and surface area of the mesh were performed with a standardized methodology independently by four radiologists blinded for the timing of the MRI. RESULTS:Of the 15 patients undergoing laparoscopic ventral hernia repair, 13 patients received an MRI both at 1 and at 13 months. Evaluation of inter-rater reliability between the radiologists showed intra-class correlations of 0.95 (95% CI 0.92-0.98) for the width, 0.96 (95% CI 0.93-0.98) for the length, and 0.99 (90% CI 0.99-1.00) for the surface area of the mesh. The change between measurement at implantation and 1-month MRI was - 0.7 cm (P = 0.023; - 3.6%) for the width and - 1.9 cm (P = 0.001; - 7.2%) for the length. The change between 1 and 13 months was - 0.06 cm (P = 0.74; shrinkage = 0.3%) for the width, - 0.12 cm (P = 0.56; shrinkage = 0.5%) for the length, and - 4.0 cm2 (P = 0.20; shrinkage = 1.0%) for the surface area of the mesh. CONCLUSION:There is excellent inter-rater reliability between radiologists when measuring width, length, and surface area of visible intraperitoneal PVDF mesh with MRI. There is no significant shrinkage between 1 and 13 months of intraperitoneal PVDF mesh after laparoscopic ventral hernia repair.

Project description:BackgroundIn ventral hernia surgery, mesh implants are used to reduce recurrence. Infection after mesh implantation can be a problem and rates around 6-10% have been reported. Bacterial colonization of mesh implants in patients without clinical signs of infection has not been thoroughly investigated. Molecular techniques have proven effective in demonstrating bacterial diversity in various environments and are able to identify bacteria on a gene-specific level.ObjectiveThe purpose of this study was to detect bacterial biofilm in mesh implants, analyze its bacterial diversity, and look for possible resemblance with bacterial biofilm from the periodontal pocket.MethodsThirty patients referred to our hospital for recurrence after former ventral hernia mesh repair, were examined for periodontitis in advance of new surgical hernia repair. Oral examination included periapical radiographs, periodontal probing, and subgingival plaque collection. A piece of mesh (1×1 cm) from the abdominal wall was harvested during the new surgical hernia repair and analyzed for bacteria by PCR and 16S rRNA gene sequencing. From patients with positive PCR mesh samples, subgingival plaque samples were analyzed with the same techniques.ResultsA great variety of taxa were detected in 20 (66.7%) mesh samples, including typical oral commensals and periodontopathogens, enterics, and skin bacteria. Mesh and periodontal bacteria were further analyzed for similarity in 16S rRNA gene sequences. In 17 sequences, the level of resemblance between mesh and subgingival bacterial colonization was 98-100% suggesting, but not proving, a transfer of oral bacteria to the mesh.ConclusionThe results show great bacterial diversity on mesh implants from the anterior abdominal wall including oral commensals and periodontopathogens. Mesh can be reached by bacteria in several ways including hematogenous spread from an oral site. However, other sites such as gut and skin may also serve as sources for the mesh biofilm.
