Résumé
This study was performed to review and evaluate a series of 1,118 patients who und-erwent microsurgical reanastomosis of previously sterilized fallopian tubes in the 134-month span encompassing January, 1980 to Febrary, 1991 at Seoul National University Hospital. Clinical characteristics of patients, pregnancy rates, and factors influencing the outcome of microsurgical tubal reversal were analyzed. Of 1,118 patients, 633(56.6%) had been sterilized by laparoscopic cautery. Loss of ch- ildren was a leading reason for requesting tubal reversal. The mean interval between tubal sterilization and reversal was 51.9 months. The postoperative tubal length was 6 cm or more in 76.0%. Nine hundred and twenty-two(82.5%) patients were followed up for more than 5 years. Overall pregnancy rate after microsurgical tubal reanastomosis was 54.8%(505 /922) with delivery rate of 71.5%(418/585), and the estimated anatomical success rate was 88.2%(814/922). In 505 pregnant cases, mean age of patients was younger and postoperati- ve tubal length was longer with statistical significance compared with 417 nonpregnant cases. Pregnancy rate was significantly correlated with postoperative tubal length, but not with method and duration of sterilization or operative procedure. These data suggest that only the postoperative tubal length is a factor influencing si- gnificantly pregnancy rate after microsurgical reversal of tubal sterilization.
