A NEW SELECTION CRITERION FOR FIMBRIECTOMY REVERSAL

Objective: To assess a new criterion for selection of patients who req uest reversal of fimbriectomy sterilization. Design: Prospective study . Setting: Division of reproductive endocrinology and infertility in a n academic center. Patients: Eight patients undergoing reversal of fim briectomy using microsurgical techniques. The prerequisite inclusion c riterion was the presence of more than 50% ampulla as shown at hystero salpingography. This is easily determined, because the isthmic length approximates one half the ampullary length. Results: The cumulative in trauterine 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 greater than or equal to 8 cm and ampullary width of g reater than or equal to 1 cm). By contrast, our new selection criterio n is based upon the more readily determined proportion of ampulla that is available for surgical neostomy.
