LAPAROSCOPY VERSUS LAPAROTOMY FOR OVARIAN CONSERVATIVE SURGERY - A RANDOMIZED TRIAL IN THE RABBIT MODEL

OBJECTIVE: Our purpose was to compare postoperative adhesion formation and reproductive outcome after the same ovarian surgical procedure pe rformed by laparoscopy or laparotomy by means of microsurgical techniq ues. STUDY DESIGN: Twenty-eight New Zealand White female rabbits were randomly assigned to laparotomy or laparoscopy for the same standardiz ed surgical procedure: both ovaries were grasped with atraumatic force ps and longitudinally incised on the antimesenteric side from the cort ex to the hilum with a microelectrode delivering a tissue power densit y of 66,666 W/cm.(2) The rabbits were then mated, and 2 weeks later a second-look laparotomy was performed by a blinded observer for the eva luation of postoperative adhesions, number of corpora lutea in each ov ary, number of embryos in the ipsilateral uterine horn, and nidation i ndex for each side. RESULTS: At second look no statistically significa nt differences were found in postoperative adhesion formation, number of corpora lutea, number of embryos, and nidation index between the la paroscopy and the laparotomy groups. CONCLUSION: Laparoscopy or laparo tomy for ovarian conservative surgery do not appear significantly diff erent in postoperative adhesion formation and reproductive outcome in the rabbit model.
