Adhesion formation and histologic reaction with polydioxanone and polyglactin suture.

A suture material associated with a minimal inflammatory response might be expected to induce less frequent and less severe peritoneal adhesions. A comparison between polydioxanone and polyglactin 910 suture was performed in a rabbit model. Ten sexually mature virgin female New Zealand white rabbits underwent laparotomy and bilateral incisions into the distal uterine cavities. The serosa of the left uterine horn was always reapproximated with polyglactin 910 suture whereas the right uterine horn was repaired with polydioxanone suture. All animals were put to death 28 days later. An adhesion score was given for each uterine horn. Representative sections were obtained for histologic review. Similar histologic responses were found in both groups. No significant difference was noted in adhesion scores between the two sutures. The present study cannot justify the use of one of these sutures over the other with regard to adhesion formation or tissue reaction.
