BACKGROUND: Tissue adhesives may be advantageous over sutures in colonic anastomoses because they do not result in potentially dangerous tight tissue approximation. METHODS: Ninety male Wistar-albino rats were used in the study. Excluding the 10 animals that constituted the control, the rest of the animals were divided in two groups: normal (N) and high-risk (HR). Only resection and anastomosis were done on half of the animals in each group. Octyl-cyanoacrylate was applied on the anastomosis of the other half of the groups. Anastomotic assessment was done at the third and seventh postoperative days. Gross anastomotic healing, mechanical strength, hydroxyproline deposition, and histopathological healing indices were used for the assessment. RESULTS: There was no difference in the third day and the seventh day groups regarding the gross healing parameters and hydroxyproline concentration. Similarly there was no difference between the third day groups in terms of mechanical healing (P = 0.669). However, the mechanical strength of the anastomosis assessed the seventh postoperative day was lower in groups in which octyl-cyanoacrylate was applied (P <0.001). Furthermore, inflammatory reaction, presence of necrosis, peritonitis, and exudate was pronounced in groups in which octyl-cyanoacrylate was applied. CONCLUSIONS: Application of octyl-cyanoacrylate to both normal and high-risk colonic anastomosis does not provide any benefit over conventional suturing at the early phase of the healing. However, octyl-cyanoacrylate seems to be detrimental at the late phase of the healing probably due to the ongoing intense inflammatory reaction.
