Studies from University of Louisville Add New Findings in the Area of Polyenes

June 2, 2014

By a News Reporter-Staff News Editor at Robotics & Machine Learning -- Current study results on Polyenes have been published. According to news reporting originating in Louisville, Kentucky, by VerticalNews journalists, research stated, "To evaluate the effect of surgical instruments handling on polypropylene mesh using scanning electron microscopy (SEM). We applied different surgical instruments, including a few robotic ones, to pieces of polypropylene mesh."

The news reporters obtained a quote from the research from the University of Louisville, "SEM was used to evaluate the morphological changes with this intervention. Straight hemostat, laparoscopic atraumatic grasper, laparoscopic needle driver, and robotic instruments (Bipolar forceps, Cadiere forceps, PK dissecting forceps and SutureCut ) were applied to the mesh. SEM images of tool-affected mesh regions in specimens handled by different instruments along with the images of intact mesh were obtained. Average mesh fiber diameters, as well as the average parameters characterizing instrument-affected regions, were measured. There was substantial widening of the fibers in specimens handled by hemostat or a needle holder. An elliptical but much longer and narrower tool marking with more surface roughness was observed inmesh handled by a grasper.A similar to 25-mu m-wide and similar to 200-mu m-long strap was split on one side from the core of the fiber caused by Cadiere . There are morphological changes to polypropylene mesh caused by instrument handling. These changes are different depending on the instrument used. These alterations vary from changes in the surface creating roughness of the fiber, compression of the mesh with narrowing of the fiber in at least one direction or actual splitting or pitting of the fiber."

According to the news reporters, the research concluded: "Since there are no data regarding the effect of these morphological changes to the ultimate functioning of the mesh, surgeons should minimize mesh handling by instruments."
