The aim of this study is to improve treatment results and SSI prevention by differential usage of the contemporary suture materials and choice of proper suturing technique. To simulate suturing process and compared two suturing techniques, two FE models were developed. Finite-element analysis (FEA) was based on experimental data of contemporary commercial sutures and soft tissue properties. We applied obtained results for abdominal wall closure in rats and compared non-absorbable suture (capron) with absorbable suture (PDS Plus) for chosen technique. Cross-sections were examined by lighting electron microscope. Afterwards, the results of patients’ treatment are also presented. It was shown that running sew was more appropriate for aponeurosis suturing compared to interrupted sew. The optimal parameters of suturing techniques were computed. Single-row running sew by PDS Plus was proved to hold wound edges for 90 days with less inflammatory response compared to other suture in the result of histological analysis. Application of contemporary synthetic absorbable suture materials with antibacterial coating for laparotomic wounds closure and anastomosis decreases local inflammatory reaction and provides the successful tissue regeneration. Application of advanced SSI prophylactics algorithm was shown to decrease risk of post-operative suppurative complications from 14.2 to 1.6 %.
