Non‐suture technique for rabbit oviduct anastomosis with 2‐octyl cyanoacrylate: A histopathologic and biomechanical analysis

Aim:  The aim of this study was to investigate histological and biomechanical properties of oviduct anastomosis with 2-octyl cyanoacrylate (OCA) in the rabbit. Material and Methods:  Sixty female rabbits were randomly divided equally into three groups: A (control), B (traditional catgut suture), and C (non-suture technique using OCA). After suture or OCA anastomosis, gross examination (adhesion formation) and histopathology (hematoxylin–eosin), ultrastructure (transmission electron microscopy), and biomechanics (bursting pressure) on para-anastomotic site were investigated on oviduct taken at 1 (A1, B1, C1) and 4 (A2, B2, C2) weeks, respectively. Results:  Adhesion score in group B was more severe than that in groups A and C at 1 and 4 weeks. Histopathology showed that acute endosalpingitis in group B was the most intense at 1 week, followed by significantly more tissue stimulation induced by catgut and foreign-body giant cells in group B than in group C at 4 weeks. Ultrastructural damage of ciliated cells was reversed partly (B2) and completely (C2) at 4 weeks. Bursting pressure in C1 was weaker than that in B1, followed by no significant difference at 4 weeks. Conclusion:  Non-suture using OCA for oviduct anastomosis can be accepted as a new-perspective technique.
