现在一般同意显微外科对纠正输卵管不育优于一般的外科手术。此法的基本原则之一是在进行组织分离或切断时止血准确。CO_2激光的主要特点为以最小的损伤不出血地切断组织。故认为它是电刀手术的另种方式。然而近来报导的在输卵管显微外科中应用 CO_2激光引起很大的争议,部分是由于缺乏CO_2激光显微外科与常规显微外科方面的对比研究。作者认为比较 CO_2激光和电刀的输卵管造口术,对恰当地判断其成功率是有意义的。自1977年1月至1981年1月对68名年龄20～38岁不孕病人做了双侧或残留的单侧输卵管造口术。
It is now generally agreed that microsurgery is better than general surgery for correcting tubal infertility. One of the basic principles of this method is to stop bleeding when the tissue is separated or severed. The main feature of CO 2 lasers is cutting the tissue with minimal damage and without bleeding. So that it is another way of electric knife surgery. However, the recently reported use of CO 2 laser in tubal microsurgery has caused considerable controversy, due in part to the lack of comparative studies on CO 2 laser microscopy and conventional microsurgery. The authors concluded that tubal ostomy compared with CO 2 laser and electrosurgical knife is meaningful for proper judgment of success rate. From January 1977 to January 1981, 68 unilateral or residual unilateral tubal ostomy was performed on 68 infertile patients aged 20 to 38 years old.
