输卵管妊娠手术治疗后再次妊娠的时机探讨

目的 分析有生育要求的输卵管妊娠患者手术后再次妊娠情况,探讨术后指导受孕、提高宫内妊娠率的方法.方法 回顾性分析1999年1月至2004年1月经手术治疗确诊为输卵管妊娠有生育要求的424例患者,追踪生育结局18～72个月.根据生育结局分为重复性异位妊娠组与宫内妊娠组,分析术后两组手术后妊娠间隔时间的频数分布及Life-table曲线分布.结果 (1)177例(41.7%)患者术后宫内妊娠;102例(24.1%)重复性异位妊娠.(2)宫内妊娠48.02%(85/177)发生在术后半年内,75 14%(133/177)在1年内,术后2年累积宫内妊娠率达94.92%(168/177);重复性异位妊娠9.8%(10/102)发生在术后半年内,48.04%(49/102)在术后18个月内,术后2年累积异位妊娠发生率为67.65%(69/102),仍有33.3%发生在手术2年后.结论 输卵管妊娠手术治疗后月经恢复即可安全妊娠,宫内自然受孕半年内增长最快,2年后宫内妊娠机率低下而异位妊娠机率仍较高.建议术后早期计划妊娠,并配以输卵管通液治疗有望提高宫内妊娠机会.

Timing of pregnancy after surgery for tubal pregnancy

Objective To investigate the outcome of pregnancy in women after surgical treatment of tubal pregnancy and measures to improve the rate of successful postoperative pregnancy. Methods A retrospective study was conducted among 424 women who underwent surgical treatment for tubal pregnancy between Jan 1999 and Jan 2004. All patients desiring a second pregnancy were followed up for 18-72 months for the outcome. Cumulative fertility and recurrence curve were compared and calculated by life-table. Results Of the 424 women with tubal pregnancy, 177 (41.7%) had intrauterine pregnancy after the operation, while 102 (24.1%) had recurrent ectopic pregnancy. Among the 177 women with intrauterine pregnancy, 85 (48.02%) became pregnant within 6 months after the operation, 133 (75.14%) within one year, and the cumulative intrauterine pregnancy rate approached 94.92% within 2 years. But among the 102 women with recurrent ectopic pregnancy, only 10 (9.8%) were pregnant within 6 months after the operation, and 49 (48.04%) within 18 months, with a cumulative ectopic pregnancy rate of 67.65%. Conclusion For women receiving surgery for ectopic pregnancy, the chance for intrauterine pregnancy can be the greatest within 6 months after operation and reduced markedly after 2 years, when recurrent ectopic pregnancy can be likely. Early plans for pregnancy and hydrotubation following the surgery may prove beneficial for raising the chances for postoperative intrauterine pregnancy.
