Microsurgical reversal of tubal sterilization: a report on 1,118 cases
1Department of Obstetrics and Gynecology, College of Medicine, Seoul National University, Korea.
Objective:
To review and evaluate a series of patients who underwent microsurgical anastomosis of previously sterilized fallopian tubes.
Design:
Retrospective clinical study.
Setting:
Tertiary care academic center.
Patient(S):
In the 134-month span from January 1980 to February 1991, 1,118 women were evaluated for microsurgical reversal of previous tubal sterilization.
Main Outcome Measure(S):
Clinical characteristics of patients, pregnancy rates (PRs), and factors influencing the outcome.
Result(S):
Of 1,118 patients, 633 (56.6%) had been sterilized by laparoscopic cautery. Loss of children was a leading reason for requesting tubal reversal. The mean interval between tubal sterilization and reversal was 51.9 months. Nine hundred twenty-two (82.5%) patients were followed up for > 5 years. The overall PR after microsurgical tubal anastomosis was 54.8% (505 of 922) with a delivery rate of 72.5% (366 of 505), and the estimated anatomical success rate was 88.2% (814 of 922). There was no statistically significant difference in the PR or in the interval from tubal reversal to conception among the different operative procedure groups. In addition, no statistically significant difference in the PR was observed regardless of the postoperative tubal length. However, the interval from operation to pregnancy decreased significantly as the postoperative tubal length increased. The pregnant patients (n = 505) were younger and had a longer postoperative tube than the nonpregnant patients (n = 417); these differences were statistically significant.
Conclusion(S):
The pregnancy rate after microsurgical reversal of tubal sterilization was not significantly correlated with the method and duration of sterilization, the operative procedure, or the postoperative tubal length.
