Abstract

OBJECTIVE
The purpose of this study is to evaluate the factors influencing the pregnancy outcomes of microsurgical tubal reanastomosis. Study design: During 64 months from Jan. 1989 to Apr. 1994, 1008 cases of microsurgical tubal reversal were performed and 764 cases of them were followed up and analysed retrospectively for more than 1 year postoperatively.
RESULTS
The overall pregnancy rate was 75.0%, ectopic pregnancy was 2.7%(not involved in overall pregnancy rate) and spontaneous abortion was 4.9%. No statistical differences were found in pregnancy rates according to the method of previous sterilization, the site of tubal reanastomosis and postoperative tubal length. The tubal length did not influence the mean interval from operation to pregnancy and pregnancy rate. But the pregnancy rate decrease was statistically significant at the age of over fourty.
CONCLUSIONS
The age was the only factor influencing the pregnancy outcomes of microsurgical reanastomosis of tubal sterilization.
