Study of two simplified microsurgical techniques for uterine horn anastomosis in rat.
This study compares two simplified techniques, which use only 2 and 4 sutures respectively, with a conventional technique with 8 sutures for fallopian tube anastomosis. Experimentally these techniques were performed on the uterine horns of fifteen female rats. A 100% patency rate was obtained with all three techniques. No difference in the mucosal, muscular and serosal regeneration was observed in the three groups at 10, 20 and 60 days. Two months after surgery, the serosa, muscularis and mucosal layers were completely continuous in all groups. The operating with 2 sutures (5'30" +/- 1'10") was significantly less than with 4 (9'09" +/- 0'55", P < 0.05 ANOVA) and 8 sutures (15'12" +/- 1'41", P < 0.05 ANOVA). A minimum inflammatory reaction to sutures was observed in all three groups at 60 days after surgery. The results suggest that with 2 sutures are all that is needed for tissue repair.
