Objective:
To assess a new criterion for selection of patients who request reversal of fimbriectomy sterilization.
Design:
Prospective study.
Setting:
Division of reproductive endocrinology and infertility in an academic center.
Patients:
Eight patients undergoing reversal of fimbriectomy using microsurgical techniques. The prerequisite inclusion criterion was the presence of more than 50% ampulla as shown at hysterosalpingography. This is easily determined, because the isthmic length approximates one half the ampullary length.
Results:
The cumulative intrauterine pregnancy rate was 50%. There were no ectopic pregnancies.
Conclusion:
Similar pregnancy rates for reversal of fimbriectomy have been reported based upon different absolute selection criteria (viz., tubal length of > or = 8 cm and ampullary width of > or = 1 cm). By contrast, our new selection criterion is based upon the more readily determined proportion of ampulla that is available for surgical neostomy.
