ABSTRACT

The results of experimental and clinical studies for the comparative evaluation of implants used in herniology of polytetrafluoroethylene (PTFE) and polyvinylidene fluoride (PVDF) are presented. Experimental investigations conducted on 200 mice, which in the anterior abdominal wall mesh prosthesis implanted. All animals, regardless of the type of implanted prosthesis, deduced from the experiment at 10, 30 th and 60 th day. Histological investigation of the submissions received. The clinical part is based on an analysis of surgical treatment results of postoperative abdominal wall hernia (POGBS) in 121 patients during the period from 2003 to 2011 patients were divided into 2 groups. The control group included 73 patients who were operated during the period 2005-2007, used PTFE graft "Ecoflon", in the main - 48 patients who from 2008 to 2011 the prosthesis was implanted PVDF - "Uniflex" firm "Linteks". In each group, selected patients whom have examined the profile of cytokines. The results of the studies found that both the material cause marked inflammatory reaction with a characteristic stepwise increased levels of proinflammatory and antiinflammatory cytokines, the dynamics of cytokines indicative of a less pronounced local inflammatory reaction to the prosthesis from the PVDF. In the application of the implant "Uniflex" a lower incidence of exudative complications in comparison with that when using the prosthesis "Ecoflon" it is preferable in clinical use.
