Physico-mechanical features of barrier bicomponent membranes in abdominal surgery.

Abstract

Revelance. Adhesive disease is one of the terrible complications with a pronounced symptom complex of the dysfunctions of the organs of the gastrointestinal tract. The frequency of this pathology in the early postoperative period with operations on the abdominal organs reaches 11% among 19-25% of all complications. Until now, it remains relevant to search for and develop methods and tools of strengthening the seam line and improve the tightness of interintestinal anastomoses. Therefore, the prospects of using the polymers and the development of such a scientific direction as implantology in medical practice are unlimited.
 Purpose. Studying the physico-mechanical features of polymer samples under the experimental conditions in vitro, in a comparative aspect.
 The materials. Bicomponent resorbable film implants based on cellulose polymers.
 The methods. Microphotography of polymeric film implants was taken with a laboratory microscope Levenhuk D320L with an increase of × 80. The thickness of the experimental samples was measured with the electronic micrometer iGaging 0-1 "/0.00005,. Membranes 10 × 10 mm were weighed with the laboratory scales. The volume and density of samples 10 × 10 mm were calculated. Determination of elasticity was carried out by fixing the angle at the moment of the integrity of the sample of the polymeric film implant in the native state.
 The results. It was revealed that an important feature of these implants is their bilateral structure, which ensures its more tight fixation to the damaged area and at the same time sufficient separation with the surrounding tissue. Thus, we selected samples No. 6, No. 1, which can be used for further in vivo studies.
 The conclusion. The use of polymeric implants is possible due to the variety of membranes in their properties and functions, which will affect the necessity and significance of the application of selected samples in experimental and clinical implantology.
