用显微技术对31例绝育后妇女进行输卵管再通术,术后随访半年以上,26例宫内妊娠,宫内妊娠率为83.9±6.6%,除2例第一胎流产后再次妊娠外,无1例宫外孕发生。本手术应注意操作的无损伤性,对口径不一致的断端作斜面切口,尽可能保护壶腹部的长度和完整性。关腹前腹腔放入漂浮混合液,不放支架,术后早期通水。文中结合本组资料对影响妊娠的有关因素进行观察分析,发现包埋结扎法复孕率较潘氏改良法高,同一种潘改法以峡部、峡与壶近段吻合较好。吻合后输卵管长度一侧在4cm以上无明显差异,若两侧均<5cm,其受孕机会较低。
Thirty-one cases of sterilized women underwent tubal recanalization by microscopy. The follow-up of more than half a year after surgery was performed. Twenty-six intrauterine pregnancies were obtained. The intrauterine pregnancy rate was 83.9 ± 6.6%. Except for the first trimester abortion, No case of ectopic pregnancy occurred. The operation should pay attention to the operation of non-invasive, inconsistent diameter of the stump for bevel incision, as far as possible to protect the ampulla length and integrity. Close the abdominal cavity before adding floating mixture, hold the stent, early after the water. Combined with this group of information on the impact of pregnancy-related factors were observed and analyzed, and found that the rate of pregnancy embedding ligation Pan improved method, the same Pan method to the isthmus, gorge and the proximal section of the better fit. Tubal length after anastomosis at 4cm or more no significant difference, if both sides were <5cm, lower chances of conception.
