The uterine horns of 40 New Zealand White female rabbits were resected and anastomosed to compare microsurgical anastomosis of the horns excised with microscissors, with a laser, and with a microelectrode. The rabbits were divided into four groups. In the first group of ten rabbits, 3 cm of tissue was resected by microscissors from each uterine horn; the cut ends were then anastomosed in one layer with 8-0 Vicryl sutures using the operating microscope. In the second group of ten rabbits, 3 cm of tissue was resected by laser from each uterine horn; the cut ends were then anastomosed in one layer with 8-0 Vicryl. In the third group of ten rabbits, 3 cm of tissue was resected by laser from each uterine horn; the cut ends were then anastomosed by "welding" the tissues with the laser. In the fourth group of ten rabbits, 3 cm of tissue was resected by a microelectrode; the cut ends were then anastomosed in one layer with 8-0 Vicryl sutures using loupe magnification. All the rabbits in the first and fourth groups became pregnant, only four became pregnant in the second group, and none became pregnant in the third group. It is concluded that the CO2 laser beam as used in this study has no place in tubal resection and reconstruction.
切除并吻合40只新西兰白兔的子宫角，以比较用显微剪刀、激光和微电极切除子宫角后的显微外科吻合情况。将兔子分为四组。第一组10只兔子，用显微剪刀从每个子宫角切除3厘米组织；然后使用手术显微镜用8-0薇乔缝线将断端单层吻合。第二组10只兔子，用激光从每个子宫角切除3厘米组织；然后用8-0薇乔缝线将断端单层吻合。第三组10只兔子，用激光从每个子宫角切除3厘米组织；然后用激光“焊接”组织进行吻合。第四组10只兔子，用微电极切除3厘米组织；然后使用放大镜放大用8-0薇乔缝线将断端单层吻合。第一组和第四组所有兔子均怀孕，第二组只有4只怀孕，第三组无一怀孕。结论是本研究中使用的二氧化碳激光束在输卵管切除和重建中无应用价值。
