Sažetak
Changes in pH within tissue, such as the extremely low pH in the stomach, can alter the physical and biomechanical properties of suture materials. In this paper, the influence of pH on the characteristics of two suturing materials used in gastrotomy on an ex vivo model of a pig was compared. In two experimental groups, glycomer 631 and polyglyconate were exposed to hydrochloric acid (HCl) for five days, while in the two control groups, the same two suture materials were not exposed to pH changes. The study was performed on pig stomachs on which the gastrotomy incision was sutured in two layers with glycomer 631 or polyglyconate. After the stomachs were filled with a certain amount of fluid, the pressure values at the dehiscence of the surgical wound of the gastric wall, the number of stitches required to suture the first and second layers of the surgical wound, the location of dehiscence of the sutures of the surgical wound of the gastric wall, and the volume of fluid required to develop dehiscence of sutures were recorded and statistically analysed. Based on the obtained results, it can be concluded that HCl has an effect on loosening surgical wound sutures and in changing their properties. Knowing the influence of HCl on monofilament sutures - glycomer 631 and polyglyconate, allows for better decision-making when choosing a suture material to close surgical wounds of the stomach wall. This study showed that polyglyconate retained its stability longer than glycomer 631 and is therefore more suitable for closing the stomach wall.
