Tissue Adhesive and Wound Healing:  Observation of Wound Healing (Tissue Adhesive vs Sutures) by Microscopy and Microangiography

Reports indicate that cyanoacrylate tissue adhesive offers many advantages when used for repair or hemostasis of injured organs.^1-5 Hatung⁶ reported that comparisons of tensile strength and histology of wounded skin and parenchymal organs revealed that closure with methyl-2-cyanoacrylate or n-butyl cyanoacrylate monomers gave results superior to those obtained by conventional suturing in wounds of parenchymatous organs but not in those of skin. However, no morphological study of wound healing in which tissue adhesive was used has been reported. The purpose of this study was to evaluate healing of wounds repaired with cyanoacrylate in the liver, kidney, and skin, by use of microscopy and microangiography.
