A report on 387 cases of microsurgical tubal reversals

Objective: To survey what factors influence the pregnancy outcome in an effort to improve the pregnancy rate (PR) after microsurgical reversal of tubal sterilization. Design: Retrospective clinical study. Patient(s): Three hundred eighty-seven patients who had microsurgical tubal reversal between March 1982 and January 1994. Intervention(s): Postoperative pregnancy outcomes were determined by telephone, letters, and direct interviews. Result(s): Pregnancy outcomes were identified in 94.1% of the total patients. The overall PR was 91.6%, of which 3.9% spontaneously aborted and 1.7% were ectopic. The probability that pregnancy occurred within the first 12 months was 0.80. The median interval from tubal reversal to pregnancy was 5.34 months. The pregnancy success rate after reversal of Falope ring sterilization was statistically significantly higher than in the other groups. Patients with reversed tubal length ≥7 cm had a statistically significantly higher PR than those with
