Reconstruction of fallopian tubes in previously sterilized patients.

Restoration of tubal patency after surgical sterilization in which the luminal continutiy is interrupted requires either uterine implantation of the patent distal segment or resection and end-to-end anastomosis of patent adjacent segments. Although it is logical to assume that after most tubal ligations the intramural segment remains normal and end-to-end anastomosis is possible, both segments should be evaluated and tested prior to the plastic reconstruction. The results of 178 operations collected from the literature and the author's 23 attempts at surgical reversal of previous tubal operations for surgical sterilization were described. The over-all pregnancy rate after resection and end-to-end anastomosis was 39.0%; after uterotubal implantation, it was 19.4%. The latter procedure was performed in 60% of the patients. The small series of reports makes it difficult to evaluate conception rates or to judge the merits of specific reconstructive operative techniques.
