DISPLACEMENT OF LAPAROSCOPIC CLIPS FROM T HE CYSTIC DUCT

The security of six different laparoscopic clips was investigated usin g 60 kryopreserved specimens of human cystic ducts. After fixation of the cystic duct the cross placed clips were distracted in axial direct ion and the maximum for ces to remove the clip were registered. The me an dislocation-force was 4.6 Newton for titanium clips and 9.3 Newton for absorbable clips with a highly significant difference (p < 0.001, Wilcoxon-test). Additional to the advantage of complete biodegradibili ty these data favour the use of absorbable clips, because of a better hold force compared to titannium clips.
