Biological tissue adhesive for mesh-application in pigs: an experimental study

Abstract

Background: Tissue damage during herniotomy may attribute to postoperative complications including chronic pain, bleeding and infection. Thus the aim of this study was to evaluate a due and simple operative procedure with intraperitoneal application of mesh with glue in an experimental model prior to use in humans.

Method: Laparoscopic insertion of a mesh was performed in three pigs. The meshes were fixed with a collagen glue. The pigs were sacrificed after 8 weeks and macroscopic and microscopic evaluation of the meshes, were performed.

Results: The intraperitoneal placed meshes did not migrate through the study period, and there was no sign of inflammation in surrounding tissue or adhesions around the meshes.

Conclusions: If these findings can be applied to human inguinal herniotomy, this may lead to significant fewer complications including development of acute and chronic pain, formation of seroma and infection. Furthermore the operation technique is very simple.
