PURPOSE: There is a paucity of high-quality evidence concerning mesh choice in open inguinal hernia repair. Using an expertise-based randomized clinical trial design, we aimed to evaluate the postoperative impact of two different mesh types on pain and discomfort, quality of life and sex life. METHODS: In two regional hospitals, male patients with primary inguinal hernia were randomized to one of two groups of surgeons that performed the Lichtenstein operation. One group of surgeons used a heavyweight polypropylene mesh (90 g/m2, Bard™ Flatmesh, Davol) while the second group employed a lightweight mesh (28 g/m2, ULTRAPRO™, Ethicon)...

We report a case of a mid-urethral sling (Advantage Fit™, Boston Scientific Corporation, Marlborough, Massachusetts) freshly removed from its original package. Upon removal from the packaging, the sling was noted to have a deformation in positioning at the midpoint, with curvature opposite the natural curve of the sling in the body. The images show the comparison to a sling with the desired positioning. Mid-urethral slings are commonly made from polypropylene mesh which has memory properties. It is important that manufacturers ensure that any steps in the processing or packaging of slings do not result in changes in the shape of the sling that may have unknown impacts on its clinical outcome...

BACKGROUND: Reversal of an enterostomy results in a high rate of incisional hernia at the ostomy site. Prophylactic mesh reinforcement of the fascial defect is typically not considered due to the contaminated nature of the case. We present the outcomes of a series of prophylactic mesh reinforcements with retromuscular, large-pore polypropylene at the time of enterostomy reversal. METHODS: Retrospective review of all ostomy reversals was performed. All cases with placement of synthetic mesh reinforcement were identified from a prospectively maintained, hernia database...

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...

An indirect inguinal hernia containing the fallopian tube alone is extremely rare in reproductive-aged women without any genital tract anomalies. Despite this rarity, early diagnosis and adequate management is important to prevent strangulation and recurrence. We present a case of an indirect inguinal hernia containing only the fallopian tube in the hernia sac, which was successfully reduced by using a laparoscopic total extraperitoneal approach and repaired with a polypropylene mesh.

Recurrence after ventral hernia repair (VHR) remains a significant complication. We sought to identify the technical aspects of VHR associated with recurrence. Patients who underwent open midline VHR between 2006 and 2013 (n = 261) were retrospectively evaluated. Patients with recurrence (Group 1, n = 48) were compared with those without recurrence (Group 2, n = 213). Smoking, diabetes, and body mass index were not different between groups. More patients in Group 1 underwent clean-contaminated, contaminated, or dirty procedures (43...

Protein adsorption is the first stage of the interaction between prosthetic materials with tissues of the body. They undergo conformational changes depending on the chemical composition and the nanotopography surface. Adsorbed proteins induce adhesion and alter the functional state of migrating cells. Plasma samples from patients were incubated with such matrices as titanium, polypropylene or polyester with fluoropolymer coating meshes. Bound peptides were analyzed by electrophoresis. Qualitative analysis of the peptides extracted from the gel was performed by chromatography-mass spectrometry...

Polypropylene mesh implants are routinely used to repair abdominal wall defects or incisional hernia. However, complications associated with mesh implantation, such as mesh-related infections, can cause serious problems and may require complete surgical removal. Hence, the aim of the present study was the development of a safe and efficient coating to reduce postoperative mesh infections. Biodegradable poly(lactide-co-glycolide acid) microspheres loaded with rifampicin as an antibacterial agent were prepared through single emulsion evaporation method...
