BACKGROUND: International guidelines on the prevention and treatment of parastomal hernias are lacking. The European Hernia Society therefore implemented a Clinical Practice Guideline development project. METHODS: The guidelines development group consisted of general, hernia and colorectal surgeons, a biostatistician and a biologist, from 14 European countries. These guidelines conformed to the AGREE II standards and the GRADE methodology. The databases of MEDLINE, CINAHL, CENTRAL and the gray literature through OpenGrey were searched...

AIMS: To present a narrated video designed to demonstrate the steps involved in a laparoscopic mesh repair of a labial hernia. METHODS: This was in a 76-year-old woman who presented with a small bowel hernia in to her left labium majus. In 2014 she had a robotically assisted radical cystectomy for bladder cancer with anterior exenteration. She developed the hernia in February 2015 and initially a vaginal approach was attempted to repair the hernia (with layered non-absorbable sutures to close the fascia over the defect) at her local hospital, although this was unsuccessful...

Processed fibers are highly present in our daily life and can be either natural, artificial (regenerated cellulose) and synthetic (made with petrochemicals). Their widespread use lead inevitably to a high contamination of environment. Previous studies focus on plastic particles regardless of their type or shape as long as they are comprised between 330μm and 5mm. On the contrary, this study focuses exclusively on fibers using a smaller mesh size net (80μm) to sample freshwater. Moreover, all processed organic fibers are considered, irrespective to their nature...

Background: One-stage direct-to-implant immediate breast reconstruction (IBR) is performed simultaneously with breast cancer resection. We explored indications, techniques, and outcomes of IBR to determine its feasibility, safety, and effectiveness. Material and Methods: We reviewed the available literature on one-stage direct-to-implant IBR, with or without acellular dermal matrix (ADM), synthetic mesh, or autologous fat grafting. We analyzed the indications, preoperative work-up, surgical technique, postoperative care, outcomes, and complications...

The authors document their experience in the use of synthetic 100% bioresorbable surgical mesh (TIGR Matrix, Novus Scientific, Uppsala, Sweden) in breast reconstruction as well as in breast aesthetic surgery. They performed a retrospective review on patients who underwent implant-based breast reconstruction as well as patients who underwent breast reduction mammoplasty procedures with the use of TIGR Matrix Surgical Mesh. When compared with other synthetic but nonresorbable meshes, it appears to show a potentially lower seroma and infection rates, but most importantly, a lower rate of revisional and mesh explantation surgeries...

BACKGROUND: Given concern for hernia mesh infection, surgeons often use biologic mesh which may provide reduced risk of infection but at the cost of decreased repair durability. We evaluated mesh coating to provide sustained release of antibiotics to prevent prosthetic mesh infection and also allow a durable repair. MATERIALS AND METHODS: Cyclodextrin-based polymer was crosslinked onto multifilament polyester mesh and loaded with vancomycin (1.75 mg/cm(2)). Pigs received modified meshes (n = 6) or normal, untreated meshes (n = 4), which were implanted into acute 10 × 5 cm ventral hernia, then directly inoculated with 10(6) colony-forming unit (CFU) of methicillin-resistant Staphylococcus aureus (MRSA)...

Extensive chest wall resection and reconstruction are a challenging procedure that requires a multidisciplinary approach, including input from thoracic surgeon, plastic surgeon and oncologist. In particular chest wall neoplastic pathology is associated with high surgical morbidity and can result in full thickness defects hard to reconstruct. The goals of a successful chest wall reconstruction are to restore the chest wall rigidity, preserve pulmonary mechanic and protect the intrathoracic organs minimizing the thoracic deformity...

John Y S Kim, Alexei S Mlodinow
Of the nearly 90,000 implant-based breast reconstructions performed in the United States, the majority use internal soft-tissue support. Aesthetically, these constructs may allow for better positioning of prosthesis, improve lower pole expansion, and increase projection. They may have particular utility in direct-to-implant, nipple-sparing mastectomies, and prepectoral reconstructions. In recent years, new permutations of acellular dermal matrices have evolved with diverse shapes, sizes, form-factor innovations, and processing characteristics...

OBJECTIVE: The aim of this study was to determine whether parastomal hernia (PSH) rate can be reduced by using synthetic mesh in the sublay position when constructing permanent end colostomy. The secondary aim was to investigate possible side-effects of the mesh. BACKGROUND: Prevention of PSH is important as it often causes discomfort and leakage from stoma dressing. Different methods of prevention have been tried, including several mesh techniques. The incidence of PSH is high; up to 78%...

INTRODUCTION: Incisional hernias are a relatively common occurrence after ostomy takedown with a incidence of 30-35%. The use of biologic mesh offers a means to bolster the stoma incision site with a lower risk of infection than synthetic mesh. METHODS: This study represents a retrospective chart review of six patients who underwent stoma takedown and had biologic mesh placed in the retrorectus position during repair from March 2015 until March 2016. RESULTS: There has been a zero-rate of hernia occurrence for the six patients who underwent stoma takedown...

PURPOSE: Cranial defects in children have been repaired with various materials ranging from autologous bone to synthetic materials. There is little published literature on the outcomes of titanium mesh cranioplasty (TMC) in calvarial reconstruction in the pediatric population. This study evaluates a pediatric cohort who underwent calvarial defect reconstruction with titanium mesh and assesses the efficacy and outcomes of TMC. METHODS: An Institutional Review Board approved retrospective review of patients ≤18 years of age who underwent cranioplasty from 1999 to 2014 at 2 centers was performed...

Technologies that use stretchable materials are increasingly important, yet we are unable to control how they stretch with much more sophistication than inflating balloons. Nature, however, demonstrates remarkable control of stretchable surfaces; for example, cephalopods can project hierarchical structures from their skin in milliseconds for a wide range of textural camouflage. Inspired by cephalopod muscular morphology, we developed synthetic tissue groupings that allowed programmable transformation of two-dimensional (2D) stretchable surfaces into target 3D shapes...

BACKGROUND: The use of surgical drains after ventral hernia repair (VHR) remains controversial. Some have concerns of increased infectious complications; others advocate that drains reduce fluid accumulation and surgical site occurrences (SSO). The aim of our study was to investigate the impact of retromuscular drains on SSO following retromuscular VHR with synthetic mesh. METHODS: Utilizing the Americas Hernia Society Quality Collaborative, patients between January 2013 and January 2016 undergoing retromuscular VHR with synthetic mesh were assessed for the presence of a drain...

Protein enzymes are the main catalysts in the crowded and complex cellular interior, but their activity is almost always studied in dilute buffered solutions. Studies that attempt to recreate the cellular interior in vitro often utilize synthetic polymers as crowding agents. Here, we report the effects of the synthetic polymer cosolutes Ficoll, dextran, and polyvinylpyrrolidone, and their respective monomers, sucrose, glucose, and 1-ethyl-2-pyrrolidone, on the activity of the 18-kDa monomeric enzyme, Escherichia coli dihydrofolate reductase...

The use of prostheses for hernia surgery, made from synthetic polymers may lead to development of postoperative complications. The reason for this can be the mismatch of the mechanical properties of meshes and the loads acting on them. The aim of this work was to investigate the behavior of 3 different hernia meshes under in vitro simulated physiological conditions followed by cyclic loadings. Meshes, Ultrapro (poliglecaprone and polypropylene), Dynamesh (polyvinylidenefluoride) and Surgipro (polypropylene) were selected...
