The role of laparoscopy in the evaluation of candidates for sterilization reversal.

An algorithm that avoids preliminary laparoscopy for sterilization reversal (SR) candidates with previous Pomeroy, loop, Hulka clip, Irving, and single-burn cautery tubal ligation techniques was used. Anastomosis was attempted only when it could be anticipated that the final length of at least one tube would be 3 cm or more. Of 259 SR candidates evaluated according to the algorithm, 235 had SR procedures. Seven of 185 patients (3.8%) who did not undergo laparoscopy were found to have inoperable tubes at laparotomy. Four of these patients had histories of a prior unilateral salpingectomy. The authors conclude that, given their criteria for proceeding with tubal anastomosis, laparoscopy can be avoided in properly selected SR candidates. The results also indicate that patients with a history of unilateral salpingectomy should undergo preliminary laparoscopy.
