经腹输卵管硅橡胶塞绝育术及其可复性研究

STUDY ON THE TRANSPERITONEAL STERILIZATION OF THE FALLOPIAN TUBE WITH SILICON RUBBER PLUG AND ITS REVERSIBILITY

采用硅橡胶阻断装置,对30只家兔作经腹硅塞堵管术,观察3～24月,绝育成功率100%;对16只绝育成功的家兔作经腹取塞术,2个月内15只家免获子宫妊娠,复孕成功率为93.75%;组织学检查表明该术式可保持输卵管管腔的连贯性,组织损伤轻微,且此种损伤在取塞后可自行修复。作者并于1984年6月起将硅塞堵管术试用于临床,共行人体硅塞堵管术232人,观察时间最长42月,最短12月,绝育失败1人,绝育成功率99.57%,1987年5月以后,对绝育一年以上的妇女8人作了取塞手术,术后1年已有7例获宫内妊娠。此法具有良好的可复性。

A blocking device made of silicon rubber was adopted for tubal blocking by transperitoneal manipulation on 30 domestic rabbits with observation for 3～24 months. 100% of sterilization incidence was obtained. Removal of the plug transperitoneally was carried on 16 of the rabbits with successful sterilization, 15 out of the 16 regained pregnancy within 2 months. Successful rate of recovery of pregnancy counted up to 93.75%. Histological study revealed that the continuity of the tubal lumina was kept by this procedure with very little damage of the tissues, and the damaged tissue would completely recover after the removal of the plug. Thus the reversibility of this procedure was recognized.This blocking procedure with silastic rubber plug was started to apply clinically on 232 women in June of 1984. The longest observation period was 42 months while 12 months being the shortest. One of them failed with the process, thus offering a successful rate of sterilization up to 99.57%. In May of 1987 the plugs were removed from 8 cases with successful sterilization over 1 year: 7 out of them have achieved intrauterine pregnancy within 1 year.
