Improving The Effectiveness Of Using Contemporary Materials In Abdominal Surgery Based On Interdisciplinary Approach

Abstract

In recent years, abdominal surgery, associated with operations on abdominal organs, has required that modern devices made from smart materials be used to reduce the incidence of postoperative complications. When performing operations on repairing hernias, surgeons begin to apply various meshes of biopolymers. However, a problem exists of adequately choosing a mesh and implantation procedure depending on the size of defect, its location, and other aspects. Shape memory stents may be utilised during gall bladder operation. Mounting shape memory stents can lead to perforation of the soft tissues. It is now more widespread practice in modern surgery to apply suture materials, utilised during operations on abdominal organs. Finite-element analysis, mechanical testing, and mathematical simulation have been used to solve the above problems, arising when applying stents, sutures, and hernia mesh. Mechanical tests have shown that lightweight mesh of polystyrene macroporous monofilament and reinforced braided polypropylene mesh implants were effective when intra-abdominal pressure was low. It was proved that single-row running sew PDS Plus secures wound edges within 90 days. Biomechanical modelling in combination with experimental data on aponeurosis and mechanical testing of sutures enabled the authors to model and calculate the stress field in the abdominal wall and find optimal suture characteristics. Interdisciplinary studies of the devices made from contemporary materials enable their proper application in medicine to reduce the number of postoperative complications.
