OC-056 CLOSURE STRENGTH OF SUTURE TECHNIQUES AND SUTURE MATERIALS

Abstract Aim Small bites closure is being implemented as standard of care (SOC) for laparotomy closure, but no consensus on which suture material to use reached. The aim our study was compare biomechanical properties four different techniques SOC. Materials & Methods Fifty porcine abdominal walls were divided into five groups: 1. SOC (2/0 polydioxanone); 2. interlocking 2/0 polydioxanone; 3. size 0 barbed 4. glycolic acid and trimethylenecarbonate (GATC); 5. suturable polypropylene mesh. small technique used the linea alba in all groups. a supra- infra-umbilical half, resulted 20 specimens per group that pulled apart tensile testing machine. Maximum strength types failure registered. Results highest measured polydioxanone arm (334.8 N ± 157.0) did not reach statistical significance compared other Infra-umbilical endured significantly higher maximum force supra-umbilical (397 vs 271 N, p<0.001). Resorbable GATC failed more often (25% 0%, p = 0.008). Conclusion When using fascial found suture, results similar among Tensile supra-umbilical. Use should be discouraged, this fails often.
