DISPLACEMENT OF LAPAROSCOPIC CLIPS TO THE HUMAN CYSTIC DUCT - EXPERIMENTS WITH ABSORBABLE AND TITANIUM CLIPS

Kryopreserved specimens of cystic ducts were used for displacement tes ts to investigate the security of different laparoscopic digs. The cys tic duct was fixed, and the transverse placed clips were distracted in axial direction and the forces registered. The median values of the s ix investigated clips ranged between 4.1 N and 11.2 N with a highly si gnificant difference (P < 0.001, Kruskal-Wallis ANOVA). In detail, bot h resorb able clips (polydioxanone, polyglyconate/polyglycol acetate) were superior to the four titanium clips (P < 0.005, Wilcoxon lest). I n addition to the advantage of complete biodegradibility, these data f avour the use of absorbable clips because holding force is better than that of titanium clips.
