[Influence of tendon surgery training on the quality of the suture].

Injuries of flexor tendons are one of the most common injuries that need surgical treatment at emergency room. Technique and quality of the surgery was performed are two factors of the utmost importance. The aim of the study was to determine influence of basic surgical training on the quality of suture. Research was divided into four surgical sessions which were held each once a week. Sutures were put by three medical students. Material that was used were deep flexor tendons dissected from fresh pig's legs. Sessions 1st, 2nd and 4th were preceded by training done by experienced surgeon. During study 90 modified-Kessler sutures without additional running suture were made. Breaking strength was assesed by tensile machine (INSTRON 4481). Time of each suture was also recorded. Outcomes were analyzed by tests: ANOVA and post-hoc LSD tests. Time significantly dropped by 64% after the first session and was held on the same level. Strength of sutures rises in each session preceded by training. There was statistically significant difference between session 1 (mean 13.58; SD 9.86N) and 2nd (mean 42.69; SD 9.27N) and 3rd (mean 38.42; SD 12.28N) and 4th (mean 57.12; SD 12.78N). Conclusions. Time of procedure significantly dropped after first teaching course and was held on the same level despite further training. Breaking strength rise in every session that was preceded by teaching course.
