A comparison of microsurgery and laser surgery for ovarian wedge resections.

To evaluate the effect of microsurgery and CO2 laser on postoperative adhesion formation after ovarian wedge resection, 30 New Zealand adult female rabbits were randomly divided into three groups of ten animals each. The control group (n = 10) had ovarian wedge resections using a scalpel with closure of the ovary performed using microsurgery technique. The second group had ovarian wedge resections performed using the CO2 laser coupled to an operating microscope. The third group (n = 10) had multiple small areas of vaporization performed on the ovary using the CO2 laser. Four weeks after the initial surgery the animals were killed and evaluated for intraperitoneal adhesions. No significant differences (P greater than .05) were found between the three groups of animals. This study suggests that the use of laser surgery may not offer a significant reduction in postoperative adhesion formation in comparison with standard microsurgery technique when performing ovarian wedge resections.
