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.
