Purpose: To compare the use of polypropylene and PTFE meshes in the treatment of incisional hernias made experimentally on Wistar rats. Methods: The experiment used 24 Wistar rats divided into three cohorts: C-A (ressection of a segment of abdominal wall), E-A (ressection and placement of PTFEe mesh), E-B (resection and placement of polypropylene mesh). After 28 days, the mesh and the surroundi...

Described is a "double mesh" technique for performing laparoscopic re-do repairs of inguinal hernias. When doing this procedure, it is virtually impossible to take down the peritoneum due to incorporation of the old mesh. This technique is therefore done by using a simple onlay of polypropylene mesh, covering the hernia defect and ensuring that sufficient staples are placed into the iliopubic t...

Background: Most surgeons are reluctant to place synthetic mesh in contaminated abdominal wall repairs for fear of mesh infection. Biologic meshes are often used in this setting; however, these meshes lack the long-term durability of permanent, synthetic mesh. The authors present a single-center case series illustrating the safety and efficacy of the use of lightweight, large-pore polypropylene...

INTRODUCTION Using mesh or a synthetic prosthesis during the laparoscopic repair of inguinal hernias has been demonstrated to be safe and effective. A new material, porcine small intestinal submucosa (SIS mesh), has been successfully used in canine and rodent animal models with excellent results. This mesh is degradable and resorbable with a marked decrease in the possibility of becoming infect...

OBJECTIVE To compare surgical fixation of polypropylene mesh (PP) and coated polypropylene mesh (PCD) using polypropylene suture and fibrin glue, as for the formation of intraperitoneal adhesions. METHODS A sample of 46 female Wistar rats were randomized into six groups: two control groups, with five rats each, were subjected to one medial incision (MI) and the other to a U-shaped incision (U...

PURPOSE To compare the inflammatory response of three different meshes on abdominal hernia repair in an experimental model of incisional hernia. METHODS Median fascial incision and skin synthesis was performed on 30 Wistar rats. After 21 days, abdominal hernia developed was corrected as follows: 1) No mesh; 2) Polypropylene mesh; and, 3) Ultrapro(r) mesh. After 21 days, the mesh and surroundi...

BACKGROUND The use of prosthetic materials to reinforce the abdominal wall is associated with a low index of recurrence; however, intraperitoneal placement of a foreign body may lead to adhesions. The present investigation was designed to determine adhesion formation with commercially available meshes implanted laparoscopically in rabbits. METHODS Three different meshes were implanted laparos...

Hypothesis / aims of study The use of polypropylene mesh to repair urinary incontinence and vaginal prolapse has decreased the recurrence of these conditions. However, it has also been related to specific complications such as vaginal erosions (1). Nitric oxide (NO) can modulate angiogenesis, vasodilation and fibroblastic reaction (2). We studied the effect of a NO donor (S-nitrosoglutathione G...

PURPOSE To compare the inflammatory reaction and the growing resistance of the abdominal wall with the use of poliglecaprone meshes and polypropylene meshes associated with poliglecaprone in the correction of abdominal defects. METHODS Seventy-seven Wistar rats were divided into three groups: CG (non-operated animals: EG (polypropylene mesh) and UG (polypropylene and poliglecaprone mesh). A m...

INTRODUCTION Prosthetic mesh infection constitutes one of the major complications following hernia repair. Antimicrobial, non-antibiotic biomaterials have the potential to reduce bacterial adhesion to the mesh surface and adjacent tissues while avoiding the development of novel antibiotic resistance. This study assesses the efficacy of presoaking reticular polypropylene meshes in chlorhexidine ...
