Tensometric characteristics of de-epithelized skin graft and polypropylene mesh implant used in hernioplasty

Abstract

A b s t r A c t -The purpose of the research work was to study the mechanical properties of a de-epithelized skin graft and polypropylene mesh prosthesis used in herniology. Tensometric studies included: tensile strength and bursting strength of suture material. The average value of tensile load of the skin graft is 51,2±4,1 N/cm 2 , of a synthetic implant -19,9±3,4 N/cm 2 . It was noted, however, that the compliance of the skin graft is higher than that of the mesh implant. The average value of the bursting strength of the skin graft by suture material is 20,1±2,7 N/cm 2 . The skin graft, while maintaining anisotropy during tensometric studies, showed the ability of compliance and tensile strength more than 2 times higher, and the bursting strength 1,4 times higher than the polypropylene implant.

Possibilities of Endoportal Infusion Therapy for Intra-Abdominal Surgical Infections Complicated by Acute Intestinal Failure

“…With endoportal infusion therapy (EIT), drugs can be administered long-term and continuously. This continuity of action is crucial in a number of diseases and their complications in abdominal pathologies, especially in peritonitis complicated by intestinal failure syndrome [3][4][5].…”

Immunohistochemical Trends of the Consequences of Mesh and Autoderm Implantation Into the Anterior Abdominal Wall in Rats

“…It is assumed that patient's own tissue will not cause a pronounced local and general inflammatory response. The autograft will sprout with vessels and newly formed connective tissue, while it will maintain its strength and anisotropy properties [4][5][6]. At the same time, there are not enough studies on the features of the inflammatory response to autoderm.…”

“…), with the organization of socio-economic space. The development of recreational activities depends on the level of recreational development of the territory, namely: the level of its natural and socio-cultural preparation, infrastructure improvement, ecological and social protection as a recreational environment[8]. During the recreational development attraction of objects and phenomena of natural, natural-man-made, social origin as recreational resources is being carried out.…”
