Brad Denney, Jorge I de la Torre
Component separation with mesh reinforcement has become the primary modality for complex abdominal wall reconstruction. However, many fundamental questions remain unanswered, such as whether underlay versus overlay mesh placement is superior, and what is the best means of suture fixation technique for mesh placement? This study presents the senior author's technique for onlay biologic mesh placement with multipoint suture fixation in combination with component separation and its subsequent low recurrence rates...

INTRODUCTION: Laparoscopic sacrocolpopexy (LSC) has established itself as a safe method for the management of pelvic organ prolapse (POP). Laparoscopic suturing is a time-consuming intraoperative task during LSC. Self-retaining barbed sutures (SBSs) are known to reduce the operative time in laparoscopic cases. The current study aimed to evaluate the efficacy and safety of SBS during the performance of LSC. MATERIALS AND METHODS: Twenty female patients with symptomatic POP were treated with LSC by an expert surgeon...

A bone's fracture could be produced by an excessive, repetitive, or sudden load. A regular medical practice to heal it is to fix it in two possible ways: external immobilization, using a ferule, or an internal fixation, using a prosthetic device commonly attached to the bone by means of surgical screws. The bone's volume loss due to this drilling modifies its structure either in the presence or absence of a fracture. To observe the bone's surface behavior caused by the drilling effects, a digital holographic interferometer is used to analyze the displacement surface's variations in nonfractured post-mortem porcine femoral bones...

Midurethral slings are used to correct urethral hypermobility in female stress urinary incontinence, defined as the complaint of involuntary urine leakage when the intra-abdominal pressure is increased. Structural and thermal features influence their mechanical properties, which may explain postoperative complications, e.g., erosion, urethral obstruction. We studied the effect of the mesh stiffness on urethral mobility at Valsalva maneuver, under impairment of the supporting structures (levator ani and/or ligaments), by using a numerical model...

Outcome of primary and incisional hernia repair is still affected by clinical complications in terms of recurrences, pain and discomfort. Factors like surgical approach, prosthesis characteristics and method of fixation might influence the outcome. We evaluated in a prospective observational study a cohort population which underwent primary and incisional laparoscopic hernia repair, with the use of a composite mesh in polypropylene fixed with absorbable devices. We focused on assessing the feasibility and safety of these procedures; they were always performed by an experienced laparoscopic surgeon, analyzing data from our patients through the EuraHS registry...
