The use of polypropylene mesh devices for Pelvic Organ Prolapse (POP) spread rapidly during the last decade, yet our knowledge of the mesh-tissue interaction is far from complete. We aimed to perform a thorough pathological examination of explanted POP meshes and describe findings that may explain mechanisms of complications resulting in product excision. We report a spectrum of important findi...

Background Polypropylene material is widely used in gynecological surgery. There are few reports regarding its carcinogenic potential. There is lack of evidence supporting tumor formation directly attributed to the use of polypropylene material. Case This patient is a 49-year-old woman with a history of stress urinary incontinence which required a MiniArc® Sling who presented with a hard, ten...

Objective: To evaluate surgical handling, prolapse correction and complication rate of polypropylene mesh. Methods: A retrospective review of patients who had pelvic floor repair using polypropylene mesh(PPM) and intra-vaginal sling(IVS), between January 2003 and July 2005. All patients were followed-up for a period of 6weeks to 12months.The effectiveness and complications following PPM inserti...

Background: The tension-free hernioplasty as introduced by Lichtenstein has gained increasing acceptance during the last decade. This study compared two methods of mesh fixation. Material and Methods: Fifty-four patients undergoing sixty repairs were randomized into two groups. In control group polypropylene mesh was secured with 2/0 polypropylene sutures and skin closed with 2/0 polyamide blac...

Intentional degradation by pro-oxidant agents, many of which are metal-based, can result in uncertainty as to the time of biodegradation. Polyacetal (POM) is a thermoplastic polymer commercially classified as an engineering polymer and contains carbon, hydrogen and oxygen. The depolymerization of POM during processing can enhance thermal decomposition. The aim of this study was to investigate t...

OBJECTIVE A retrospective cohort study of 640 male polypropylene production workers in Germany was performed to evaluate the reported association between colorectal cancer and polypropylene. METHOD The follow up period was 1956 to 1990. Expected numbers of cancers were derived from incidence rates adjusted for age and calendar year from the Saarland cancer registry. RESULTS Three colorectal...

The effects of surface treatment of flax fibers featuring vinyltrimethoxy silane (VTMO) and maleic anhydride-polypropylene (MAPP) on the mechanical properties of flax/PP composites were investigated. α-polypropylene (α-PP) and β-polypropylene (β-PP) were used as matrices for measuring the mechanical properties of the flax fiber/polypropylene (flax/PP) composites. Flax/PP composites composed of ...
