BACKGROUND: To study comparatively the healing and the adhesion formation in rats' spleen that were submitted to spleen surgical trauma and sutured with octil-2-cyanoacrylate (DE group) and 25-poliglecaprone thread (CA group). METHODS: Three groups of 10 Wilstar male rats each were used. They were anaesthetized according to the COBEA technique rules and were submitted to xyphoid-pubic laparotomy and the spleen was exposed. A 4mm deep spleen injury at the inferior pole in diaphragmatic face was done with a Metzenbaum scissors. In the CA group the injured was sutured with continuous stitches using 25-poliglecaprone thread; in the DE group octil-2-cyanoacrylate was used; and no suture was done in the CO group (control). After 14 days the rats underwent euthanasia and adhesions were noted in an appropriate protocol. Hematoxilin-eosin and Pycro-sirius stain films were made and readings were done in a double bind way. RESULTS: At DE group less adhesions, less abscess formation and smaller healing reaction of foreign body were seen than the CA group. Both showed equivalent quantity of young (type I) and mature (type III) collagen. CONCLUSION: Octil-2-cyanoacrylate provoked less macroscopic adhesions than 25-poliglecaprone thread and it didn't induce healing reaction of foreign body type, showing effective repair in the traumatic injury of rats' spleen.
