Abstract (124) SUMMARY This study involved 60 sexually mature, healthy, non-pregnant female rabbits weighing 2.5-3 kilograms. Rabbits were housed individually for 2 weeks prior to surgery to be sure that they were not pregnant. The rabbits were randomly divided into 6 equal groups, each containing 10 rabbits with special mark fixed to their ears. In each group different method of cutting or hemostasis was used. Group 1: Cutting was done by the scalpel in the left uterine horn and by unipolar microelectro-cautery in the right horn. Hemostasis was done by unipolar micro-coagulation in both sides. Group 2: Cutting was done by the scalpel in the left uterine horn and by the scissors in the right horn. Hemostasis was done by unipolar micro-coagulation in both sides. (125) Group 3: Cutting was done by the scissors in the left uterine horn and by unipolar micro-electrocautery in the righ horn. Hemostasis was done by unipolar micro-coagulation in both sides. Group 4; Cutting was done by the scissors in both uterine horns. Hemostasis in the right uterine horn was done by bipolar micro-coagulation and in the left horn by unipolar micro-coagulation. Group 5: Cutting was done by the scissors in both uterine horns. Hemostasis was done by unipolar micro-coagula-tion in the right uterine horn and by sutures in the left horn. Group 6: Cutting was done by the scissors in both uterine horns.Hemostasis was done by bipolar micro-coagulation in the right uterine horn and by sutures in left uterine horn. After that, uterine horn reanstomosis was done by single, seromuscular interupted sutures using (126) dexon 6/0, Four weeks later, a second look laparotomy was done to assess adhesions formation, horn patency, and the segments of anastomosis were excised for histopathological examination to assess inflammatory reaction, gaint cell formation, fibrosis, mucosal regeneratiOn and MUSCle diSruption. All data were compared statistically by student ”t”-test. This study showed that: 1-Tubal cutting by unipolar micro-cautery was associated with statistically significant increase (P< 0.05) in muscle disruption, mucosal damage and fibrosis, in comparison to tubal cutting by scissors or the scalpel. 2-There was no statistically significant difference (P> 0.05) regarding adhesion formation, horn patency, inflammatory reaction and foreign body reaction between unipolar micro-cautery, scalpel and scissors. 3-It was no statistically significant difference (P> 0.05) regarding adhesion, horn patency, muscle disruption mucosal damage, inflammatory reaction and foreign body reaction between scalpel and scissors. (121) 4-It was found that, hemostasis by micro-coagula-tion (unipolar or bipolar) was associated with statistically significant reduction (P< 0.05) in adhesion formation, in compare to sutures. 5-There was no statistically significant difference (P> 0.05) regarding fibrosis, horn patency, muscle disruption, mucosal damage and inflam- matory reactions between unipolar, bipolar I 1 I micro-coagulation ancl sutures. |
