[Relationship between microsurgical tubal reversal and ectopic pregnancy].
OBJECTIVE
To study the correlation between microsurgical tubal reversal after tubal sterilization and ectopic pregnancy.


METHODS
1029 women who underwent microsurgical tubal reversal were followed up. The causes of ectopic pregnancy were analysed and discussed.


RESULTS
960 intrauterine pregnanciess and 12 ectopic pregnancies occurred. The 12 ectopic pregnancies were all tubal ones, among which 2 had intrauterine pregnancies. The rate of ectopic pregnancy in the 1029 women was 1.17%, and in the pregnant cases was 1.23%. The ratio of intrauterine pregnancy to ectopic pregnancy was 1:80. The rates of ectopic pregnancy in the 1st, 2nd year and 2 years later after tubal reversal were not significantly different respectively among the tubal reversal and among the pregnant cases. The rates of ectopic pregnancy in the 1st and 2nd 6 months after tubal reversal were not statistically different. The early tubal hydrapertubation could only increase the chance of ectopic pregnancy. The sterilization method, reversal mode, and interval between sterilization and reversal were not related to the ectopic pegnancy.


CONCLUSIONS
When the lesion in the sterilized position is completely removed, the sutures being through the tubal mucosa and the early tubal hydrapertubation not carried out, the chance of ectopic pregnancy can not be increased after tubal reversal. The contraception 6 months after tubal reversal is not related to ectopic pregnancy.
