Surgical procedures are becoming more frequent in the clinical care of reptiles and the procedures for wound closing must provide a fast and efficient healing devoid of complications. Cyanoacrylate (CA) adhesives are an alternative used in mammals but short and intermediate-length chain CA may be toxic to tissues and their tolerance in reptiles has been poorly documented. The objective of this study was to evaluate the histological tolerance of three CA adhesives in experimental soft-skin surgical incisions of Trachemys scripta. Under general anaesthesia, two, 1 cm full-thickness, incisions were induced on the dorsal aspect of each hind limb in twelve turtles. The four wounds of each turtle were randomly closed using octyl-cyanoacrylate (SurgisealVet™), butyl-cyanoacrylate (VetBond™), ethyl-cyanoacrylate (Superglue™) or monofilament absorbable glyconate (Monosyn® 2/0) as control. On days 2, 7, 14 and 21 after the surgical procedure, three turtles were selected at random and biopsies of their four wounds obtained for histopathological study. Clinically, butyl-CA formed visible precipitates but the three CAs were well tolerated; however, most of the wounds suffered dehiscence in contrast to the sutured wounds. Histologically, only ethyl-CA was associated with moderately increased acute inflammation. Healing was slowed by the dehiscence of the wounds that occurred in equal proportion with the three CAs tested. In conclusion, butyl-CA and octil-CA showed good tissue tolerance and could be an alternative to conventional suturing if tension across the wound is limited.
