Microsurgical reversal of female sterilization: the role of tubal length.
A group of 25 women who had undergone tubal sterilization by a variety of techniques underwent microsurgical reanastomosis. The length of tube remaining and the segments of tube involved were carefully noted preoperatively, but were not used as a basis for selection of patients. The only criterion utilized for selecting patients was the presence of fimbriae on at least one side. In all patients, anatomical patency was achieved at surgery. Normal intrauterine pregnancy was directly related to tubal length. Of seven patients who had less than 3 cm of tube, none achieved pregnancy. Of seven patients who had 3 to 4 cm of tube, three achieved a normal intrauterine pregnancy. Among 11 patients who had over 4 cm of tube, all 11 achieved a normal intrauterine pregnancy. No significant difference in pregnancy rate was noted in women who had short segmants of ampulla so long as total tubal length was adequate.
