Male infertility is a rare but certainly underestimated iatrogenic complication of inguinal hernia repair. The use of polypropylene mesh, recommended by the European Hernia Society, either via the traditional, open or laparoscopic approach, is responsible for surrounding inflammation followed by fibrosis, but there is no proven increase in vas deferens obstruction found in the literature. Prevention is essential to reduce the incidence of this complication including screening for patients at risk and mastery of surgical techniques...

Bacterial cellulose modified with chitosan (MBC) is an innovative biomaterial used in regenerative medicine which may potentially improve treatment outcomes mesh for hernia repair surgery by facilitating better absorption in native tissue with less risk of mesh-related infections. The aim of the present study was to evaluate the biocompatibility of mesh based on MBC, and determine whether immunological reactions occur due to hypersensitivity to the implants. Forty five Imp:WIST rats were randomly assigned to be implanted with one of three mesh types: simple polypropylene mesh (n = 15), mesh modified by bacterial cellulose only (n = 15) and MBC mesh (n = 15) and evaluated after one and three months following intramuscular implantation...

AIMS AND OBJECTIVES: Polypropylene meshes have been increasingly adopted for correction of pelvic organ prolapse due to its lower recurrence rate when compared to surgeries without meshes. The study of the interaction of these materials with the host tissue may contribute to the development of materials with best biocompatibility and, consequently, less complication rates. MATERIALS AND METHODS: The present study compares the inflammatory reaction of standard-weight (SW) and lightweight (LW) meshes (72 g/m216g/m2 respectively), implanted in the abdomen of 20 adult rats, which were euthanized in four or 30 days...

Ventral hernia is a public health issue and millions of meshes are used to repair abdominal wall defects every year. Polypropylene-based composite meshes represent an important class of materials for intraperitoneal repair, but the meshes generally give rise to infection, seroma, migration, and adhesion, leading to severe consequence or even reoperation. Here, a facile and versatile one-way fabrication of lightweight, highly permeable, and biocompatible composite meshes with superior antiadhesion properties is proposed by modifying polypropylene meshes with well-defined polydopamine nanocoating...

BACKGROUND: Chronic pain after inguinal hernioplasty is the foremost side-effect up to 10-30% of patients. Mesh fixation may influence on the incidence of chronic pain after open anterior mesh repairs. METHODS: Some 625 patients who underwent open anterior mesh repairs were randomized to receive one of the three meshes and fixations: cyanoacrylate glue with low-weight polypropylene mesh (n = 216), non-absorbable sutures with partially absorbable mesh (n = 207) or self-gripping polyesther mesh (n = 202)...

Mesh fixation with the use of adhesives results in an immediate and total surface area adhesion of the mesh, removing the need for penetrating fixation points. The purpose of this study was to evaluate LifeMesh™, a prototype mesh adhesive technology which coats polypropylene mesh. The strength of the interface between mesh and tissue, inflammatory responses, and histology were measured at varying time points in a swine model, and these results were compared with sutures. Twenty Mongrel swine underwent implantation of LifeMesh™ and one piece of bare polypropylene mesh secured with suture (control)...

This paper describes, for the first time, the use of oxidized buckypaper (BP) as a sorbent membrane of a stir-disc solid phase extraction module. The original device, consisting of a BP disc (d = 34 mm) enveloped in a polypropylene mesh pouch, was designed to extract organic micropollutants (OMPs) from environmental water samples in dynamic mode. High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was used to analyze the extracts. Several classes of pesticides and pharmaceuticals were chosen as model compounds to evaluate key parameters affecting the recovery rates...

OBJECTIVE: Polypropylene meshes are one of the most frequently used patches in inguinal hernia repairs. This material was proved to be not completely inert, and may cause inflammatory responses like foreign body reactions. One of the physical results of these inflammatory reactions against the mesh is mesh shrinkage which is responsible for recurrence and pain. In this study, we aimed to investigate the effects of the suture technique on mesh shrinkage. METHODS: 36 animals were used for the study...

OBJECTIVE: Vaginal mesh exposure is the most common complication from mesh use in prolapse and incontinence surgery. Angiogenesis is an essential component of tissue healing, and defective angiogenesis plays a role in chronic wounds. We hypothesized that patients with exposures will have impaired angiogenesis as evidenced by altered tissue vascular endothelial growth factor A (VEGFA) expression and microvessel density. The study objective was to compare angiogenesis in women with vaginal mesh exposures, those with vaginal mesh without exposures, and in women who were mesh-naive...

Male sling for urinary incontinence is usually accompanied by very good results, with a small number of complications,but, when appear, they may be redundant. Voluminous urethral stone developed on suburethral sling as a result of sling erosion into the proximal urethra is an extremely rare complication (following the analysis of cases published on the internet, the authors of this article no longer identified another similar case). We present the case of a patient who presented in our clinic for severe and permanent urinary incontinence, perineal discomfortand pain that was influenced by position...

Here we present a 32-y-old rhesus macaque (Macaca mulatta) with a large recurrent ventral incisional hernia. The initial surgery included midline celiotomy for treatment of endometriosis, in which the animal developed a hernia that was repaired with interposition of mesh. Hernia recurrence at 1 y resulted in a defect measuring 7 × 13 cm, with loss of abdominal domain. Skin breakdown was noted with areas of exposed mesh through the skin with associated acute on chronic infection. Clinically, the animal was lethargic, not eating, and failing to thrive...

Purpose: The use of prosthetic biomaterials for reconstructing and reinforcing the posterior wall of the inguinal canal reduces the incidence of hernia recurrence. Cost, availability of mesh, and perhaps reluctance to adopt a new technique are factors which prevent widespread practice of hernioplasty in low-resource settings. Use of resterilized mesh significantly reduces the cost of hernioplasty and is safe. Patients and Methods: Sheets of 30 cm × 30 cm polypropylene mesh were cut into 16 cm × 8 cm to produce mesh strips which were repackaged into SELFSEAL® (Medical Action Industries Inc...
