Effect of Surgical Adhesive on the Uterus of Rabbits Following Occlusion

ABSTRACT

Purpose/Aim of the Study: The present study investigated the effect of surgical adhesives on the uterus of rabbits and the histomorphology alterations following occlusion, to improve the clinical treatment of abnormal fallopian tube with surgical adhesives for in vitro fertilization and embryo transfer (IVF-ET). Materials and Methods: The experimental rabbits received laparotomy and occlusion of the uterus by surgical adhesive adjacent to the two fallopian tubes, while the control rabbits only received laparotomy. The body weight, hysterosalpingography, and histomorphology were measured to evaluate the uterine occlusion at 1 and 6 months after surgery. Results: There was no significant difference in the mortality rate or body weight between the experimental and control groups. In the experimental group, 38 uterine cavities were identified in 19 rabbits, of which 97.37% were occluded, with expanded uterine cavity and tissue oppression at 1 month after surgery. In total, 33 uterine cavities out of the 36 in the control group were occluded, with proliferation of new stratified epithelial cells observed at 6 months after surgery. In the control group, 20 uterine cavities of 10 rabbits were observed to be absent of occlusion at 1 month after surgery, while 18 uterine cavities in the remaining 9 rabbits were also absent of occlusion at 6 months after the surgery. Conclusion: Surgical adhesives are effective in occluding the uterus of rabbits without adverse effects, supporting their potential clinical use to treat the occlusion in abnormal fallopian tubes prior to IVF-ET.
